Chapter A
Season of planting
July to December.
Planting material
Use plantable size grafts propagated through approach, soft wood or epicotyl grafting.
Field preparation
Dig pits of 1 m x 1 m x 1 m in size. Fill in with topsoil mixed with 10 kg of FYM.
Planting
Plant the grafts at the centre of the pits with ball of earth intact and keep the graft
union 15 cm above the ground level. Stake and water the plants immediately after planting.
Spacing
Adopt any one of the following spacings depending on requirements.
1. Under conventional system of planting: 7x7m or 10x10 m
2. High Density Planting : 5 m x 5 m (400 plants / ha)
3. Ultra High Density Planting: 3 x 2 m
4. Double hedge row system : Adopt a spacing of 5 m x 5 m within double rows
and 10 m between sucessive double rows (266 plants / ha)
Irrigation
Regular watering till establishment. For cultivation under irrigated conditions,
adopt drip system of irrigation.
Intercropping
Short duration crops like legumes, vegetables, groundnut etc. can be raised during
pre- bearing age.

Fertigation schedule for UHDP Mango (to be applied at weekly interval)
Canopy management
Remove rootstock sprouts and low lying branches nearer to ground to facilitate easy
cultural operations. Remove overlapping, intercrossing, diseased, dried and weak branches in
old trees to get good sunlight and aeration. Carry out judicious pruning of the internal
branches during August – September, once in three years. Do not allow flowering upto three
years by removing the inflorescences as and when they appear. Retain two healthy shoots
by trimming away the weak shoots among the crowded terminal shoots during August-
September annually. Prune back 20 cm of annual growth of the terminals immediately after
harvest.
Growth regulators
Spray NAA @ 20 ppm at flowering to increase the fruit set and retention. During
February 0.5% Urea (5 g / lit.) or 1% Potassium nitrate (10 g / lit.) may be sprayed to induce
flowering, if trees do not flower by that time. Spray 2% KNO3 at mustard size to increase fruit
size and retention of fruits. Spray 2 % sulphate of potash at pea stage and 15 days after to
improve yield and quality.
During off year Paclobutrazol @ 0.75 g a.i. per metre of canopy radius in full bearing
tree during first fortnight of September to get maximum number of fruits and yield.

Aftercultivation
Garden Land
Give spade digging at bi-monthly intervals and earth up. Prune the suckers at monthly
intervals. The dry and diseased leaves are removed and burnt to control the spread of leaf
9
spot diseases. Male flowers may be removed a week after opening of last hand. The plants at
flowering may be propped. Cover the peduncle with flag leaf to prevent stalk end rot. Cover
the bunches with banana leaves to avoid sun scald.
Wet land
Form trenches in between alternate rows and cross trenches at every 5th row. The
trenches are periodically deepened and the soil is spread over the bed. Surface diggings may
be given at bi-monthly intervals and desuckering at monthly intervals. Remove the male flower
a week after opening of last hand. Prop plants at or prior to flowering. Cover the peduncle with
flag leaf and the bunch with leaves to avoid sun scald. For ratoon crops, in respect of
Poovan, Monthan and Rasthali, allow the follower at flowering of the mother plant and remove
the other suckers at harvest.
Perennial banana
Give surface digging with spade once in two months. Give one deep digging with
spade during January – February. Other operations as in garden land.
Hill banana
Give four forkings in January, April, July and October. Remove outer sheaths to keep
the corm inside the soil and ward-off borer. Maintain two bearing plants and two followers per
clump along the contour.
Growth regulators
To improve the grade of bunches, 2,4-D at 25 ppm (25 mg / l.) may be sprayed in
Poovan and CO 1 banana after the last hand has opened. This will also help to remove
seediness in Poovan variety. Spray CCC 1000 ppm at 4th and 6th month after planting.
Spray Plantozyme @ 2ml / l at 6th and 8th month after planting to get higher yield.
Micronutrients
Spray micronutrients viz., ZnSO4 (0.5%), FeSO4 (1.0%), CuSO4 (0.2%) and
H3BO3 (0.2%) at 3rd, 5th and 7th MAP to increase yield and quality of banana. Apply 25 kg
ZnSO4 basally.
Bunch cover
Use transparent recyclable polyethylene sleeves with 2% (during cool season) and 4%
(during summer season) ventilation to cover the bunches immediately after opening of the last
hand
Intercropping
Leguminous vegetables, beetroot, elephant foot yam and sunnhemp. Avoid growing
cucurbitaceous vegetables.
Special Practices
Mulching with 100µm degradable polythene sheet immediately after planting conserves soil
moisture and also suppresses weed growth. Surface digging and earthing up of soil at bi-monthly
intervals facilitates better root system. Desuckering should be done at monthly intervals. Removal
of dried leaves at periodical intervals reduces the disease spread. At the time of bunch
emergence, prop the plants using bamboo or casuarina poles. After the completion of female
phase, remove the male bud for better fruit development. After opening of the last hand, withered
styles and perianth to be removed to avoid finger tip disease.
Bunch thinning i.e., removal of one to two small bottom hands from the bunch (keeping only 7 to 8
hands) facilitates uniform bunch development and this practice is recommended for export
purpose. Cover the peduncle with flag leaf to prevent main stalk end rot. Cover the bunch with
degradable polythene sleeves (2 - 4 % ventilation) or with white colour non-woven UV stabilized
10
polypropylene sleeves to avoid sunscald and to produce quality bunch. After harvesting, the
pseudostem should be cut leaving a stump of about 0.6m height to nourish the developing
daughter sucker.
Plant protection
Pests
Rhizome weevil Apply or sprinkle carbofuran 3G 33g/sucker at the time of
planting.
Pseudostem borer Remove dried leaves periodically and keep the plantation clean.
Remove the side suckers up to eighth month and destroy.
Do not dump infested materials in the manure pit. Infested trees
should be uprooted, chopped into pieces and burnt.
Trap and kill adult weevils by chopping pseudostem chopped
into small pieces.
Banana aphid Apply any one of the following insecticides
Carbofuran 3G @166g /plant
Dimethoate 30EC 1.0 ml/l.
Methyl demeton 25 EC 2.0ml/l.
Bunchy-top The Banana Aphid, Pentalonia nigronervosa is the vector of
Bunchy-top virus disease.
The spray may be directed towards the crown and pseudostem
base upto ground level at 21 days interval at least thrice.
To prevent the disease,
i) Use virus-free suckers
ii) Paring and pralinage: Pare the corm and sprinkle 40 g of
carbofuran 3 G over the corm (Before sprinkling, corm should
be dipped in mud slurry).
iii) Destroy virus affected plants.
Thrips Spray dimethoate 30 EC 1.0ml/l.
Lace wing bugs: Spray any of the following insecticides
Dimethoate 30 EC 1.0ml/l.
Methyl demeton 25 EC 1.0ml/l.
Quinalphos 25EC 4.0ml/l.
Nematode
Pre-treat the suckers with 40 g of carbofuran 3G. If pre-treatment is not done, apply 40
g of carbofuran around each plant one month after planting (refer selection and pretreatment
for alternative technology). Then grow sunnhemp after 45th day and incorporate one month
later. Press mud application @ 15 t per ha one month after planting and neem cake 1.5 t per
ha one month after planting. Intercrop with marigold @ 4:1 ratio. Apply Pseudomonas
fluorescens (Pf1) liquid formulation @ 4 lit/ha @ 2nd , 4th and 6th month after planting through
drip system to manage panama wilt and nematode complex.
11
Diseases
Selection and pre-treatment of suckers
Select sword suckers of 1.5 to 2.0 kg weight, free from diseases and nematodes. Trim
the roots and decayed portion of the corm, cut the pseudostem leaving 20 cm from the
corm and grade the suckers to size. To avoid wilt disease, infected portions of the
corm may be pared, dipped for 5 minutes in carbendazim 0.1% solution (1 g in 1 l of
water) solution for Rasthali, Monthan, Neyvannan, Virupakshi and other wilt
susceptible varieties.
Pralinage with 40 g of carbofuran 3 CG granules per sucker (dip the corm in slurry
solution of 4 parts clay plus 5 parts water and sprinkle carbofuran to control
nematodes).
Sow sunnhemp on 45th day; incorporate it after about a month. This operation reduces
nematode build up.
Bunchy-top
Use virus-free suckers for planting
The banana aphid, Pentalonia nigronervosa is the vector of bunchy-top virus disease
Destroy virus affected plants by inserting a gelatin capsule containing 200 mg 2,4 - D
into the corm 7 cm deep using capsule applicator or inject 5 ml 2,4 - D solution (125
gm/lit of water) into the pseudostem by using the injection gun. The plant collapses and
topples in 3 – 5 days
Apply carbofuran 3G @ 166 g /plant or spray dimethoate 30EC @ 1 ml/l or methyl
demeton 25 EC @ 2 ml/l to control vector
The spray may be directed towards crown and pseudostem base upto ground level at
21 days interval at least thrice.

3. Acid Lime: Citrus aurantifolia (Christm) Swingle; Rutaceae
Varieties: PKM 1, VRM 1 Tahithi lime, Balaji (Tenali), Vikram, Rasraj, NRCC -7, NRCC -8 ,
Phule Sharbathi
Soil and Climate: Areas with dry climate and moderate rainfall (<750 mm) are best suited.
Deep well drained medium black, loamy or alluvial soils rich in organic matter and devoid of
calcium carbonate are good. The optimum pH is 6.5 -7.0
Propagation: Budded plants on Rough lemon or Rangpur lime rootstocks are good. Since
seeds are highly polyembryonic and seedlings are true to type, propagation by seeds is also
recommended. Layering is adopted for VRM 1 Tahithi lime.
Irrigation: Young plants need regular watering during post-monsoon period at an interval of
8-10 days and at 5-7 days during summer months. Water is applied around the periphery of
the tree in a ring and basin system (double ring) so that tree trunk should not come in direct
contact with water. Avoid water stagnation. Adopt drip system for new plantations.
Manures and Fertilizers per plant: ‘N‘ to be applied in two doses during March and
October.FYM, P2O5 and K2O are to be applied in October. Pseudomonas @ 20 g and VAM
@ 200 g per plant may be added along with FYM application.

N 200 g 100 g 600 g
P 100 g 25 g 200 g
K 100 g 40 g 300 g
After cultivation: Remove branches of main stem up to 45 cm from ground level. Periodical
removal of dried twigs along with one inch length of basal green wood and destroying them
by
burning should be done. Spray Zinc sulphate @ 0.5% (500 g /100 lit of water) thrice in a
year (March, July and October) after the emergence of new flushes.
The basins should be mulched with dry leaf waste or paddy husk with about 10 cm thickness
so as to arrest weed growth and also to conserve soil moisture, thereby improving the fruit
quality.
Intercropping: Legumes and vegetable crops can be raised during pre-bearing age.
Harvest: Starts bearing from 3 - 4 years after planting. The tree flowers and produces fruits
almost all the year round, but there are three major flushes in June-July (Mrig Bahar),
September-October (Hast Bahar) and January – February (Ambi Bahar). Fruits of
September-October flowering (Hast Bahar) harvested during summer months are most
remunerative. The fruits mature in 5-6 months after flowering and are harvested when the
14
colour just starts changing. Peak harvesting period is July-September and November-
January.
Post harvest handling
Harvested fruits are graded according to size and colour and packed in bamboo baskets or
wooden crates lined with green foliage. Treating the fruits with 4% wax emulsion followed by
pre-packing in 200 gauge polythene bags with 1 % ventilation improves the shelf life for
more than 10 days.

4. Sweet Orange (Citrus sinensis (L) Osbeck) ; Rutaceae
Varieties : Sathugudi, Batavian, Mosambi, Malta blood red, Cutter Valencia.
Planting material
Budded plants (Rootstock: Rangpur lime is the best, now rough lemon is also
preferred).
Preparation of field
Dig pits at 75 cm x 75 cm x 75 cm in size at 7 x 7 m spacing. Fill up the pits with top
soil and 10 kg of FYM. Plant the budded plants in the centre of the pits and stake it. Plants
should be trained during first 3 years to have a well distributed frame work at 45 cm height
on a single trunk.
Irrigation
Immediately after planting, irrigate copiously and continued once in 10 days. Irrigations
should be regular during fruit development. Avoid water stagnation near the plant. Water
should never come in direct contact with the trunk of the tree; for this reason, double ring or
check bund method is best suited for this crop. Drip irrigation is advisable in saving of
irrigation water. Stopping irrigation 1 or 2 months prior to flowering is beneficial
After cultivation
No regular pruning except removing dead, diseased and over crowding branches after
harvesting of the fruit. The basins should be mulched with dry leaf waste or paddy husk with
about 10 cm thickness so as to arrest weed growth and also to conserve soil moisture,
thereby improving the fruit quality.
Intercropping: Legumes and vegetable crops can be raised during pre-bearing age.
Harvest: Starts bearing from 5th year after planting. Sweet orange takes 9-12 months for
maturity. Being non-climacteric fruits should be harvested only after full maturity.
Yield: 30 t / ha.
17
Pest : Sweet Orange
Spacing : 6x6m, pit size 75x75x75 cm. Planting during May – June and Sep – Oct.
Manures and Fertilizers: Apply twice in a year during June and October.
For Palani Hills
Apply 700:375:600 g / tree NPK along with AM fungi (Glomus fasiculatus) @ 1 kg / tree.
Manures are to be applied in the basin 70 cm away from the trunk and incorporated. Apply
micronutrients as suggested for sweet orange. Apply agricultural lime or Dolomite at 4 kg /
tree during January – February once in 2 – 3 years. This should not be combined with other
chemical fertilizers.
18
After cultivation: Remove water shoots, rootstock sprouts, dead and diseased shoots.
Remove laterals of the main stem up to 45 cm from ground level. Basins should be provided for
each tree with gradient slope.

Soil and Climate
Grapes prefer dry humid condition for better growth and yield. Areas within the
temperature range of 15 to 40oC and rainfall lies between 500 and 900 mm are suitable for
this crop. Rain should not coincide with vine growth after pruning and bunch ripening phase.
Cloudy weather with high relative humidity, fog and low temperature are not suitable for
flowering and fruit set. This results in build up of fungal diseases which ultimately leads to
loss in yield.
Well-drained rich loamy soil with a pH of 6.5 - 7.0 with low water table with EC less than
1.0 is congenial for its cultivation. The soil depth should be atleast 1 m for proper root
development and vine establishment. The rootstocks viz., Dogridge and 110 R can be used to
overcome the high soil pH, drought and salinity in irrigation water with EC upto 8 m.mhos
cm2. The day time temperature ranging from 20oC to 35oC is optimum for proper vine growth
and establishment.
20
January - February. The rootstock after planting in the soil requires regular irrigation at
periodical interval in its field capacity. In light textured soils, the rootstocks should be irrigated
daily. There is no fertilizer requirement upto one month after planting since the roots are not
active and require some time for settling. The rootstock plant once settled in the soil should
be allowed to grow as such till 50 days from the planting time. The number of shoots sprouted
from each plant helps in increasing the root density. These plants are cut back from the base.
One month after sprouting, the plants should be retained with 2-3 healthy disease free and
vigorous shoots. These shoots are tied with bamboo or casuarina poles with the help of korai
fibre or jute thread. On 5-6 months old grown up rootstocks, in situ grafting is done with the
scion sticks with 2-3 healthy buds of 15-25 cm length. The in situ grafting can be performed
during June to September. The rootstocks are decapitated at 1.5 feet height from the ground
level before grafting. At the time of grafting, temperature of 32-35OC and high relative
humidity of 80 per cent in the atmosphere and rootstocks with high sap flow are preferred for
getting high graft take. Simple wedge grating is the best method for in situ grating for getting
maximum success for the establishment of grapes vines. Whereas the best time for planting
the own rooted cuttings is June-July.
Spacing
Spacing interval of 4 x 2 m for commercial grape varieties and 3 x 2 m for Muscat
Hamburg.
Irrigation
Irrigate immediately after planting and on the 3rd day and then once in a week. Withheld
irrigation 15 days before pruning and also 15 days before harvest.

Training
Once new shoots are started from the scion portion after grafting or from the own
rooted cuttings, train the shoots straight by tying them to bamboo sticks or casuarina poles.
The girth of the graft union tend to increase during the graft growth, during this time the
polythene strips have to be removed to avoid the girdling damage or constriction over the main
stem. For getting uniformity in growth of grapevines by giving recut at 3rd node position above
the graft joint. Immediately after the recut, faster sprouting will be noticed and this needs
proper management for the cordon development by adopting ‗‘Halt and Go‘‘ method. The
growth is nipped of one feet below the level of pandal or ‗‘Y‘‘ trellis and then trained to form
trunk, primary and secondary arm (cordon) of the grapevine. In this method, the newly growing
shoots are cut at 6-7 leaf stage when the growth attains 8-9 leaf. The vines are trained with
single stem upto pandal with a stalk on tipping at 2 m height. The main arms are developed and
trained on opposite directions. On further tipping, secondary and tertiary arms are developed
for spreading all over pandal.
21
Pruning
In general, four bud level of pruning for Pachadraksha, Bangalore Blue, Anab- e-Shahi,
Dil Kush and Arka hybrids, five bud level for Red Globe, five to seven bud level for Muscat
Hamburg and two bud level for Sharad Seedless, Thompson Seedless and its clones (After
sub cane formation at 7 t h node) may be adopted. Before pruning, the pruning severity
and bud level can be determined by bud forecasting technique. Canes of weak and immature
nature should be pruned back to one or two buds to induce vegetative growth.
Pruning Season
Summer crop: Pruning in December - January and harvesting during April - May.
Winter crop: Pruning in May-June and harvesting during August - September
Double pruning for double cropping in Muscat Hamburg (Panneer)
For getting high yield with quality fruits, adoption of double pruning and double
cropping system is the best for Muscat Hamburg (Panneer). The first pruning for getting
summer crop can be practiced during December - January and harvesting is made during in
April - May. The second pruning can be practised during May-June and harvesting during
August - September. The vines are allowed for 2-3 months period of rest after harvesting till
December. Apart from Muscat Hamburg, the varieties like Anab-e-Shahi, Clone A-18/3,
Manjari Medika and H-516 are also highly suitable for adoption of double pruning for double
cropping.

Special viticultural practices
Shoot thinning
There will be lot of new shoots of more than 100 at faster rate after pruning from the
buds of vines. More number of shoots will result in overcrowding which compete for nutrients
and water and prone for pest and disease incidence with poor productivity. For growing the
seedless varieties for export, less than 0.75 shoot, domestic market purpose 1 shoot and for
Muscat Hamburg (Panneer) 2 shoots per square feet area should be retained. Shoot thinning
should be practised at 4-5 leaf stage.
Tipping
Tipping is practised by the retention of 9-11 leaves above the last cluster and tying of
clusters in the pandal after the fruit set for berry development and maturity in the bunches.
Further tendrils are also removed.
Nipping
Nipping is practised by removing the emerged shoots from axillary buds and terminal
growth at 12th to 15th bud position from the base.
Nematodes
Apply 60 g of carbofuran 3G or 20g of per vine a week before pruning and the plots are
irrigated profusely. The soil should not be disturbed for at least 15 days. Thereafter normal
manuring may be done. Application of neem cake @ 200g/vine also can be administered to
control nematodes. Alternatively, application of Pseudomonas fluorescens formulation in talc
containing 15 x 108 colony forming units/g @ 100g/vine 30 cm away from base of the vine at
least 15cm depth at the time of pruning.
Diseases
Powdery mildew
Spray wettable sulphur @ 0.3% or dust sulphur @ 6 -12 kg/ha in the morning or
azoxystrobin @ 150 a.i./ha (600 ml/ha) at 30 days after pruning five times at 10 days

added till there is no deposit in the knife.
Quality improvement in Muscat Hamburg
To get uniform ripening in Muscat, spray the bunches with 0.2% Potassium chloride
(2 g /l) at 20th day after berry set, followed by another spray on 40th day. Dip the clusters of
Thompson seedless and other seedless varieties at calyptra fall stage with 25 ppm GA (25
mg / l) and repeat again at pepper stage to increase the size of berries.
Retention of 9 leaves above the last cluster with the foliar application of 10 ppm GA 3
when the berries at parrot green stage and 0.5 ppm of homobrassinolide was found to be the
best for high yield and quality.
Foliar application of chelated EDTA calcium @ 0.2 % combined with boric acid @ 0.1
% during early berry development was highly effective for getting high yield and for reducing
berry cracking.
Quality improvement in seedless grapes varieties
Extensive use of various plant growth hormones in seedless commercial grapes
varieties is very common for enhancing the yield land quality. But one should be very careful
about the stage of use and the concentration of these hormones. Gibberellic acid (GA 3)
application reduces number of flowers and also results in elongation of berries and bunches.
Plant growth regulators like Brassinolide, Benzyl Amino Purine (6-BAP) and CPPU increase
the size of berries. The schedule and the concentration of different hormones for balanced
crop, quality bunches and berries in seedless grape varieties
Days after pruning Stage of bunch Hormone Concentration

Use of GA3 during cloudy weather should be avoided. This results in excess flower
dropping and reduces the fruit set. Likewise GA3 should not be used during full bloom stage to
fruit set period. To ensure better results for GA3 on berry size and elongation, may be applied
by spraying or dipping bunches.

Crop Regulation - Bahar Treatment
There are three distinct flowering seasons with corresponding harvesting periods-rainy,
winter and spring. It is desirable to take only one crop in a year.
In South India the rainy season crop is preferred even though it is of poor quality, since the
price is high at this time.
Guava is a current season bearer. Inducing flowering or bahar treatment in guava includes
management practices like withholding of water, irrigation, fertilization and use of growth
regulators in association with pruning technique.

Papain extraction
Papain has several industrial uses, the important one being in brewing industries.
It is used as ―meat tenderiser‖ and in textile and leather ―sanforization‖ processes and
drugs.The method of extraction of papain from papaya fruits is simple. The latex should be
tapped from immature papaya fruits. Select 75 to 90 days old fruits. On the selected fruit, give
incisions (cut) with a razor blade or stainless steel knife. The cuts should be given from stalk to
tip of the fruit. The depth of the cut should not be more than 0.3 cm. Four such cuts are
given spaced equally on the fruit surface. Tap the latex early in the morning and complete the
tapping before 10.00 A.M. Repeat the tapping four times on the same fruit at an interval of
three days. The cut should be given on the fruit surface in places not covered by previous cuts.
The latex collected from all the plants in a day should be pooled, shade dried in an aluminium
pan or tray and passed through a 50 mesh sieve to remove all foreign matter. In large
34
plantations, vacuum driers can be adopted with advantage. Papain produced by artificial
heating will have better colour and high quality. Add Potassium meta-bi-sulphite (KMS) at
0.5 % for better colour and keeping quality.
The latex should be dried very rapidly at temperatures of 50 to 55oC. Stop drying
when the dried product comes off as flakes having a porous texture. Powder the dried papain
by means of wooden mallets or in electrically operated granulators and sieve the powder
through 10 mesh sieve. Pack the powder in polythene bags in convenient quantities and
seal them. Put the sealed bags in a tin container and seal it after evacuating air. Exposure
to air deteriorates the quality of papain and vacuum sealing is therefore necessary. For large
scale manufacture of papain, vacuum sealing machine and a granulator will be useful.The
green papaya fruits after extraction of papain can be used for pectin manufacture and ―tuity
fruity‖ or they can be allowed to ripen and made into other products. The CO 2, CO 5 and
CO 8 varieties of papaya released by Tamil Nadu Agricultural University, Coimbatore are
ideal for papain production.
Yield
The yield of crude papain is as follows: CO 2: 600 kg / ha, CO 5 & CO 8: 800 kg / ha.
Seed Technology
Germination improvement
Store the seeds in airtight containers. Soak t h e seeds in 100 ppm GA3 for 16

the year, which may not be desirable commercially. To avoid this trees are given bahar
treatment. In this treatment, the irrigation is withheld two months prior to the bahar followed by
light earthing up in the basin. This facilitates the shedding of leaves. The trees are then
medium pruned 40-45 days after withholding irrigation. The recommended doses of fertilizers
are applied immediately after pruning and irrigation is resumed. This leads to profuse flowering
and fruiting. The fruits are ready for harvest 4-5 months after flowering.
In tropical condition, there are three flowering seasons, viz., January-February (ambia
