Practices of Crop Production
Exercise No. 1
Site Selection for Crops

Name: Kristine Joy M. Espinoza Section:2-1

PROCEDURE:

1. Evaluate your farm/backyard garden by filling up the second column of Table

1a (Site evaluation sheet) using information obtained through steps 2-4 below.
2. Get the climatic data from the website of PAGASA weather station in your
locality. Summarize the climatic data and write these in the appropriate box
under the column Site Characteristic.
3. Get the data online for soil physical properties. If the data is not available
online, you will do the “Feel and Roll” method to determine the soil texture in
your area. Write these in the appropriate box under the column Site
Characteristic.
4. Based on observation and research, briefly describe the site as to topography,
accessibility, socio-economic condition, and facilities, and other amenities. Write
your description in the appropriate box under the column Site Characteristic.

1. Research on the soil and climatic requirements of the assigned crop plant and
write the information in Table 1b (Soil and climatic requirements of the
assigned crop). Use local references except when these are not available.
Write the references used in the space provided in Table 1b.
2. Each of you will be assigned one of the crops listed below.
a. Ampalaya h. Cassava o. Onion
b. Anthurium i. Cauliflower p. Sugarcane

e. Cabbage l. Garlic s. Taro
f. Cacao m. Mango t. Tobacco
g. Carrot n. Mungbean u. Ubi

3. Based on the information in Table 1a and Table 1b, state whether the crop
plant assigned to you is suited to the area or not. Explain your conclusion. If
there is a need for modifications or improvements in the area, state them.
Write this on the space (Conclusion and Recommendation) provided
below Table 1b.

Conclusion and Recommendation:

By doing this activity, I learned that determining the site description,
especially the climate and soil characteristics are essential in cropping/planting.
It has also something to do in deciding what kind of crops you will cultivate. In
short, the kind of area location is a big factor in planting. Because crops may be
suitable/not suitable in a particular site description (climate, soil, topography,
accessibility….). Because in each crop, there’s a climatic, and soil requirements
that should be acquired for the ideal crops to harvest. Just for example the
carrots, It is not suitable in our site because this is cool season crops, as we can
notice the most plantation of carrots located in high area like in Benguet, Nueva
Vizcaya and other places where it is suitable.
As an Agribusiness student, I recommend to every famers and to everyone
who wants to do planting, that it is really important to become well-informed and
knowledgeable about the crop growing requirements and selecting a good site
for their crops. Attending to seminars and other program is a good idea, to gain
more information that will help in planting. Having adequate knowledge is a key
factor to attain a desirable quality of the chosen crops you want to cultivate.
