 I. INTRODUCTION

In recent years, more people are looking for special types of rice that offer health benefits

and unique flavors. This trend gives local farmers and businesses a great chance to provide

different kinds of rice that meet these needs. Our proposal focuses on starting a farm in Brgy.

Rizal, Science City of Muñoz, Nueva Ecija, where we will grow special-purpose rice—CLS2

variety that not only tastes great but also has added nutritional value.

By taking advantage of the area's rich soil and good weather, we plan to produce

high-quality rice that appeals to health-conscious consumers and food lovers. Our goal is to use

sustainable farming practices and modern techniques to make our rice stand out in the market.

This proposal outlines our plan for growing and producing special-purpose rice, including

the steps we will take, the facilities we will use, and the resources we will need. Through

partnerships and smart marketing, we hope to support the local economy while encouraging

healthier eating choices among our customers.

 II. PLANT/FARM DESCRIPTION AND LOCATION

 IV. PRODUCTION PROCESS

A. Seed Quality

Seed quality is vital for producing special-purpose rice, affecting germination rates, crop

health, and yields. High-quality seeds should have a germination rate of at least 85%, be free

from impurities, and be uniform in size and weight. They must also be disease-free and stored at

moisture levels of 12-14% to prevent fungal growth. Quality seeds lead to better yields, uniform

crops, and lower costs, while also improving resistance to diseases and pests. To maintain high

seed quality, it’s important to source from certified suppliers, conduct regular germination tests,

and store seeds properly. Prioritizing seed quality enhances the overall productivity of rice

production

B. Crop Calendar

Using a crop calendar allows better planning of all farm activities and the cost of

production. A cropping calendar is a schedule of the rice growing season from the fallow period

and land preparation, to crop establishment and maintenance, to harvest and storage.
 C. Land Preparation

It is a crucial step for the soil to undergo in land preparation as it helps to aerate the soil,

improve the roots availability of oxygen. Proper land preparation helps eliminate weeds that

compete with rice plants for nutrients, sunlight, and water that are vital in achieving higher

yields. A well-prepared land improves water drainage, which is important for rice cultivation,

especially in both wet and dry seasons.

A. Steps in Land Preparation

The following tasks are the process needed for Land Preparation:

● Cleaning and Weeding In this operation, it is the removal of weeds,

debris, and crop residues to prepare the field.

● Pre–irrigation This process will be taken 2 days before

plowing.

● Plowing (Primary Tillage) A plowing method turns over the soil to a

depth of 15-20 cm to break up compacted

layers and incorporate organic matter.

● Harrowing (Secondary Tillage) To achieve a uniform soil surface, suitable for

rice seedlings, a disk or tine harrow will be

used.

● Furrowing This technique is used to create furrows in the

rice field that allows for better placement of

 fertilizers and nutrients, ensuring they are

evenly distributed and accessible.

Effective land preparation sets the foundation for successful rice cultivation, especially

for specialized varieties. Ensuring each step is carefully executed results in better yields and

high-quality produce.

This figure shows the process of Land Preparation:

Figure 2. Land Preparation Process

D. Planting

Rice cultivation is an essential food crop that meets the global food demands and ensures

food security given that the Nueva Ecija is the Rice Granary of the Philippines due to it being the

largest supply of rice grains. Before planting, a need for careful planning must be considered.

Rice crops can be either direct seeded or transplanted. In direct seeding, seeds are sown directly

in the field. While in transplanting, seedlings are first raised in seed beds before they are planted
in the field. When choosing the suitable planting method, the locality, type of soil, rice

ecosystem, and availability of inputs and labor, should be considered. Choosing when to plant is

crucial to establishing the crop in the field. Timely planting into a well prepared seedbed will

help produce a fast growing, uniform crop that will have higher yields and better competition

against weeds and other pests. The best time to plant depends on locality, variety, weather, water

availability, and the best harvest time. Planting at the same time (or within a 2 week window) as

the neighboring fields can help to minimize insect, disease, bird, and rat pressure on individual

fields. Direct seeding requires 60−80 kg of seeds per ha, while transplanting only requires 40 kg

per ha, at 2 plants per hill.

Different methods of Planting Rice

The following the most typical approaches in growing rice:

● Wet growing: Rice traditionally grows in flooded areas, or paddies. First, water (several

inches deep) is poured into the paddies until the plants are submerged, and then, before

harvesting, it is drained from the rice growing plantation.

● Dry growing: The crop grows in fields that are not flooded. This method is good for

growing paddy crops in regions with reduced rainfall or a lack of water supplies.

● Upland growing: Is well-suited for areas, such as hills or mountains, where the

topography does not permit flooding. Terrace farming allows for growing crops on slopes

causing minimal soil erosion.

● Aerobic (aeroponic) growing: Is employed in places where water is scarce or flooding is

not an option. The crop grows in soil that drains effectively and is only watered sparingly

when needed.
● System of Rice Intensification (SRI): This type of rice growing prioritizes plant density,

soil condition, and irrigation to boost yields. It calls for planting seedlings at a younger

age, with more space between them, and with less water than conventional approaches

imply.

● Aquaponics, or rice-fish growing: Is a technique for cultivation that combines wet

growing with fish farming. In flooded areas, fish are farmed alongside crops, and their

feces serve as fertilizer.

E. Water management

Rice is not only the staple food, but also constitutes the major economic activity

and a key source of employment and income for the rural population. Water is the single

most important component for sustainable rice production, especially in the traditional

rice growing areas of the Region. Reduced investments in irrigation infrastructure,

increased competition for water and large water withdrawals from underground water

lower the sustainability of rice production.

There are several approaches to water management in rice production, including:

● Alternate wetting and drying (AWD): A method of irrigation that can reduce water

consumption

● Raised-bed system: Rice is grown on raised beds that are well-drained and not

continuously flooded

● Direct seeded rice (DSR): Can make more effective use of early season rainfall and save

irrigation water for the dry season

● Drip irrigation: Can save water without reducing grain yield

 ● Intermittent dry spells: Strategic periods of drought can promote plant water use

efficiency

● Bunds: Should be well compacted and at least 20 cm high to avoid overflowing during

heavy rainfall

● Field channels: Can control the flow of water to and from the field

● Leveling: Can avoid ponding, or raised patches

F. Soil fertility

Many crop issues stem from poor nutrient management and imbalances in the soil. For

planting the CLS2 variety in a 5-hectare area, it’s crucial to manage soil fertility effectively.

Implementing Site-Specific Nutrient Management (SSNM) will allow us to optimize fertilizer

use and achieve higher yields. By adopting Site-Specific Nutrient Management, and applying

efficient fertilizer use, the CLS2 crop variety could lead to increased yields and higher profits.

The following are the steps to be conducted in the field:

➢ Soil testing - Testing the soil is crucial to assess the current nutrient profile of the

specific variety CLS2.

➢ Fertilizer application - By supplementing additional fertilizers this will ensure

that the rice gets all the nutrients it requires at critical growth stages.

Following these steps will help ensure the successful growth and productivity of the CLS2 rice

crop on the 5-hectare plot.

G. Weed management
 Effective weed management is essential for the successful cultivation of special purpose

rice (CLS2) variety that is being planted on a 5-hectare plot. Weeds compete with rice plants for

vital resources like nutrients, water, and sunlight, leading to reduced yields and increased

production costs. If not properly managed, weeds can reoccur, presenting a significant challenge

for rice farmers. A strategic approach is necessary to eliminate these factors that hinder crop

yields and global food production.

Weed management remains a significant hurdle for crop producers, particularly rice farmers, as

once fields are infested, control costs can escalate. Implementing a plan of action for weed

control is crucial in rice cultivation.

Weed Control Activities:

➢ Manual Weeding: This involves physically removing weedy rice to prevent future

infestations.

➢ Land Preparation: Evenly spreading rice straw during land preparation helps to

eliminate weedy rice seeds on the soil surface.

➢ Final Tillage and Land Leveling: Ensuring an even water depth during final tillage and

land leveling helps limit the germination and emergence of weedy rice seedlings.

These practices are vital for managing weeds effectively and ensuring the optimal growth and

productivity of the CLS2 special purpose rice variety.

H. Pests and diseases

a. Pest and Disease Management

This approach is crucial for the success of our CLS2 special purpose rice.

Diseases caused by fungi, bacteria and viruses can significantly reduce yields and
 income. Globally, over 20 species of insects damage rice crops. A best approach

to control these insect pests is the application of Integrated Pest Management

(IPM).

Figure. IPM Strategies

➢ Inspection: Regular field inspections help detect early signs of pests and diseases.

By spotting issues early, we can take immediate action to prevent its damage.

➢ Identification: This strategy allows us to choose the most effective and targeted

management practices, minimizing unnecessary interventions.

➢ Monitoring: Keeping a constant monitoring over the rice field provides essential

data on pest populations and disease development. This information is crucial for

recognizing patterns and planning timely interventions.

➢ Action: Utilizing the data from inspection, identification, and monitoring, we can

deploy suitable control strategies. These might include cultural practices,

biological controls, mechanical methods, or specific chemical applications.

 ➢ Evaluation: After implementing the control measures, it's crucial to assess their

effectiveness. This process aids in upgrading our future pest and disease

management strategies, ensuring our approach remains efficient and sustainable.

I. Harvesting

Harvesting is the process of collecting the mature rice crop from the field.

Paddy harvesting activities include reaping, stacking, handling, threshing, cleaning, and

hauling. These can be done individually or a combine harvester can be used to perform

the operations simultaneously. It is important to apply good harvesting methods to be able

to maximize grain yield, and minimize grain damage and quality deterioration.

Harvesting rice consists of the basic operations which can be done in individual steps or

in combination using a combine harvester.

➢ Reaping: Reaping is a critical step in the CLRICE2 production process, as it

directly impacts the quality, yield, and efficiency of the final product. By

harvesting the crop at the optimal maturity stage, growers can maximize the

concentration of active ingredients, ensuring the effectiveness of the subsequent

extraction process. Timely reaping also prevents losses due to factors like adverse

weather conditions, pests, and diseases. Additionally, efficient harvesting

techniques minimize damage to the plant material, preserving its integrity for

optimal extraction. In essence, reaping sets the foundation for successful

CLRICE2 production by providing high-quality raw material for the subsequent

processing steps.
➢ Threshing: Threshing is a crucial step in the CLRICE2 production process, as it

separates the grain from the husk and straw. This separation is essential for

several reasons. Firstly, it prevents the grain from deteriorating due to moisture

and fungal growth, which can occur when the grain remains in the husk.

Secondly, threshing allows for efficient drying of the grain, reducing the risk of

spoilage. Thirdly, it facilitates the cleaning process, removing impurities like dirt

and debris that can affect the quality of the final product. By ensuring proper grain

separation and preparation, threshing contributes to the production of high-quality

CLRICE2.

➢ Cleaning: Cleanliness is paramount in the CLRICE2 production process, as it

directly impacts the quality, efficiency, and safety of the final product. A clean

production environment minimizes the risk of contamination, ensuring that the

synthesized materials remain pure and free from impurities. This purity is

essential for the accurate and reliable performance of the CLRICE2 system.

Additionally, a clean workspace reduces the likelihood of equipment malfunctions

and breakdowns, leading to increased productivity and reduced downtime. By

maintaining strict cleanliness standards, the production process can be optimized,

resulting in higher yields and lower costs. Ultimately, a clean environment fosters

a safer workplace for employees, protecting them from potential hazards

associated with chemical substances and equipment.

➢ Hauling: The transportation of raw materials and finished products, is a critical

component of the CLRICE2 production process. It ensures the timely and

efficient movement of essential materials between various stages of production,

from the initial sourcing of raw materials to the final delivery of the finished

product. Effective hauling optimizes production schedules, minimizes downtime,

and prevents bottlenecks in the manufacturing process. It also plays a crucial role

in maintaining the quality of raw materials and finished products by safeguarding

them during transportation. Additionally, efficient hauling contributes to cost

reduction by minimizing transportation expenses and reducing lead times. In

essence, hauling is the backbone of the CLRICE2 production process, enabling

seamless operations and contributing to the overall success of the manufacturing

enterprise.

➢ Field Drying: Field drying is a crucial step in the CLRICE2 production process,

as it significantly impacts the quality and storability of the harvested rice. By

exposing the harvested rice to sunlight and wind, field drying reduces the

moisture content of the grains, preventing mold growth, insect infestations, and

other forms of deterioration. This process also helps to harden the grain, making it

more resistant to breakage during subsequent handling and milling. Additionally,

field drying can improve the milling yield and the overall quality of the milled

rice, resulting in a superior product. While modern drying techniques exist, field

drying remains a cost-effective and environmentally friendly method, particularly

for small-scale farmers.

➢ Stacking/Piling: Stacking or piling plays a crucial role in the CLRICE2

production process, particularly in the drying and storage phases. By stacking the

rice, a larger surface area is exposed to air, facilitating efficient moisture

evaporation and accelerating the drying process. This minimizes the risk of

spoilage and ensures the rice reaches optimal moisture content. Additionally,

stacking allows for efficient storage in warehouses, maximizing space utilization

and optimizing inventory management. Proper stacking techniques also help

maintain the quality of the rice by preventing damage and contamination. In

essence, stacking is a vital step in the CLRICE2 production process that

contributes to product quality, efficiency, and overall productivity.

➢ Bagging: Bagging plays a crucial role in the CLRICE2 production process,

offering several significant benefits. Firstly, it acts as a protective barrier,

shielding the rice grains from external contaminants, pests, and adverse weather

conditions. This ensures the quality and integrity of the harvested rice. Secondly,

bagging facilitates efficient handling, storage, and transportation of the rice. It

prevents spillage, damage, and contamination during these processes.

Additionally, bagging helps maintain the moisture content of the rice, optimizing

its storage life and preventing spoilage. By preserving the quality and quantity of

the harvested rice, bagging contributes to the overall success of the CLRICE2

production process.
J. Drying - Drying reduces grain moisture content to a safe level for storage. It is the most

critical operation after harvesting a rice crop. When rice is harvested, it will contain up to

25% moisture. High moisture level during storage can lead to grain discoloration,

encourage development of molds, and increase the likelihood of attack from pests. It can

also decrease the germination rate of the rice seed. It is important to dry rice grain as soon

as possible after harvesting— ideally within 24 hours. Delays in drying, incomplete

drying or ineffective drying will reduce grain quality and result in losses. Paddy drying

methods include traditional and mechanical systems with varying technological

complexity and capacities for either farm or commercial level.

Traditional Drying System - Traditional drying systems are still practiced in many areas

because of its low cost and ease of management.

➢ Sun drying: Spreading grains under the sun, on mats and pavements

○ Mat drying - used in small to medium-scale drying where threshed grain are

placed on mats, nets, or canvas

 ○ Pavement drying - often used in large-scale drying for grain collectors and

millers, where grains are laid on pavements specifically made for drying

➢ Field drying and stacking: A method for pre-drying hand-harvested crops before

threshing where farmers cut rice panicles in the field and stacked them in small

piles on top of the crop stubble

Mechanical Drying System: In this system, mechanical dryers are used to remove water

from wet grains by forcing either ambient air or heated air through the grain bulk.

➢ Heated air drying: Employs high temperatures for rapid drying. The drying process is

terminated when the desired final moisture content is reached. It uses the following types

of dryer:

● Batch dryer - can be used by farmers, contractors, and small rice mills

● Re-circulating batch dryer - can be used by commercial rice mills and

cooperatives

● Continuous flow dryer - not very common, but used by some larger billing

enterprises that handle large volumes of wet paddy

➢ Low-temperature drying or in-store drying: Controls the relative humidity rather than

the temperature of the drying air so that all grain layers in the deep bed reach equilibrium

moisture content. This can be done using the

● In/store dryer - produces very high quality grains but requires long drying

time, i.e., four days to two weeks

➢ Solar drying: Latest drying technology that is able to simulate sun drying even during

rainy conditions. This is done through:

● Solar bubble dryer - can be locally-built and used by smallholder farmers

➢ Grain cooling: Cools the grain to safe storage conditions instead of drying it, allowing

grains to be conserved for longer periods

K. Storage - The purpose of any grain storage facility is to provide safe storage conditions

for the grain in order to prevent grain loss caused by adverse weather, moisture, rodents,

birds, insects and microorganisms like fungi. In general, it is recommended that rice for

food purposes be stored in paddy form rather than milled rice as the husk provides some

protection against insects and helps prevent quality deterioration. However, when rice can

be stored as brown rice, 20% less storage capacity will be needed. Brown rice is rice

grain with its hulls removed but not polished. Under tropical conditions brown rice has a

very short shelf life, approximately two weeks. Rice storage facilities take many forms

depending on the quantity of grain to be stored, the purpose of storage, and the location

of the store.
Storage systems can be through bag, bulk, or hermetic containers.

➢ Bag storage:Grain is stored in 40−80 kg bags made from either jute or woven

plastic

➢ Bulk storage: Grain is stored in bulk at the farm or at commercial collection

houses

➢ Hermetic storage: Grain is stored in an airtight container so that that moisture

content of the stored grain will remain the same as when it was sealed. These

storages can extend germination life of seeds, control insect grain pests, and

improve headrice recovery. Examples include:

● IRRI Superbag - available to farmers and processors at low cost

● Cocoon - commercially available

● Other locally available containers - useful in rural settings, where local containers

can be easily converted into hermetic storage systems

 L. Milling and processing - Milling is a crucial step in post-production of rice. The basic

objective of a rice milling system is to remove the husk and the bran layers, and produce

an edible, white rice kernel that is sufficiently milled and free of impurities. Depending

on the requirements of the customer, the rice should have a minimum number of broken

kernels.

A rice milling system can be a simple one or two step process, or a multi stage process.

➢ One step milling: Husk and bran removal are done in one pass

➢ Two step process: Removing husk and removing bran are done separately

➢ Multistage milling: Can be done in the village or local consumption or

commercially for marketing rice; rice undergoes a number of different processing

steps, such as:

 1. Pre-cleaning

2. Dehusking or dehulling

3. Paddy separation

4. Whitening or polishing

5. Grading and separation of white rice

6. Mixing

7. Mist polishing

8. Weighing of rice

M. By Product - The main by-products of rice are rice straw, rice husk or hull, and rice bran.

➢ Rice straw: Produced when harvesting paddy. Straw comes from what is left on

the plant after it is harvested and the grains are threshed.

➢ Rice husks or hullsare: Generated during the first stage of rice milling, when

rough rice or paddy rice is husked.

 ➢ Rice bran: Produced during the second stage in milling, the whitening or

polishing process, when the bran layer is removed from the brown rice kernel.

N. Rice varieties

➢ CLRICE 1: The white aromatic rice variety has slender grain, a maturity period

of 112-119 days, plant height of 107-114 cm, and grain yield of 2-5 tons per ha,

depending on location and crop management. It has a relatively high milling

potential of 64.51%.

➢ CLRICE 2: Pigmented and aromatic rice that has higher yield potential (3-5

tons/ha) and milling recovery (60.67%)

➢ CLRICE 3: Pigmented and aromatic rice that have yield potential of (2-4

tons/ha; and 52%).

V. Waste Disposal System

Rice, a staple food for billions worldwide, is inextricably linked to human civilization.

However, its cultivation and processing generate significant amounts of waste, primarily in the

form of rice husk, straw, and bran. The mismanagement of these byproducts poses a serious

threat to the environment and public health, necessitating the implementation of robust rice waste

disposal management systems. It is crucial for individuals, businesses, and policymakers to

embrace sustainable practices in rice production and rice waste management. By doing so, we

can minimize environmental pollution, reduce economic losses, and contribute to a more robust

and efficient agricultural sector. Let us recognise the untapped potential of rice waste and work

together towards a future where every grain of rice is valued, and no resource goes to waste.

Rice husk: The protective outer layer of the rice kernel, has been regarded as a waste product for

a very long time. However, they can be a great fuel for bioenergy production due to their high

cellulose and lignin content. Ingenious methods, such as processing rice husks into biofuels or

biomass pellets, have been devised by scientists to tap into the husks’ energy potential. We may

lessen our reliance on nonrenewable fossil fuels and cut down on greenhouse gas emissions if we

convert rice husks into renewable energy sources.

Rice bran: The outer layer of the rice grain is typically removed during the milling process.

However, it contains a wealth of valuable compounds, including antioxidants, vitamins, and

essential fatty acids. Scientists have developed methods to extract these beneficial components

from rice bran, turning it into a sought-after ingredient in the pharmaceutical and cosmetic

industries. Rice bran oil, with its nutritional properties, is gaining recognition, while rice bran
extracts are used in skin care products for their skin-enhancing benefits.

Rice straw: The stalks left behind after the rice grains are harvested, are traditionally burned or

discarded. However, forward-thinking innovators are finding ways to utilize rice straw for

sustainable packaging materials. By transforming rice straws into biodegradable alternatives of

plastic, we can significantly reduce the environmental impact of packaging. Additionally, rice

straw can be used as animal feed or converted into organic fertilizers, providing agricultural

benefits and closing the loop in rice production.
