Sowing is the critical step of putting seeds into the soil, ensuring proper spacing and depth for optimal germination and plant growth.

Broadcasting involves scattering seeds evenly over the field by hand, though it may lead to uneven distribution and requires more seeds.

A seed drill sows seeds at the correct depth and covers them with soil, ensuring uniform germination and saving seeds.

Transplanting allows seedlings to grow initially in a protected nursery before being moved to the main field, ensuring stronger plants.

Rice seedlings are first raised in a nursery and then transplanted into puddled fields to ensure proper spacing and better yields.

Manuring enriches the soil with essential nutrients and improves soil structure, water-holding capacity, and microbial activity.

Compost is made from decomposed organic matter like plant residues and kitchen waste, providing natural nutrients to the soil.

Fertilizers are industrially manufactured chemicals that provide specific nutrients like nitrogen, phosphorus, and potassium to plants in concentrated forms.

Irrigation ensures that crops receive adequate moisture for germination, growth, and yield, especially during periods of insufficient rainfall.

The moat or pulley system is an ancient method where a bucket is lowered into a well and pulled up by oxen or humans to lift water.

Drip irrigation saves water by allowing it to drip slowly to the plant roots, minimizing evaporation and wastage.

Weeding is essential to eliminate weeds that hinder crop growth by competing for resources and harboring pests.

Herbicides are chemicals specifically designed to control or destroy unwanted weeds without harming the crop when used correctly.

Crop protection involves various measures to safeguard crops from damage caused by insects, fungi, weeds, and animals throughout their growth.

Insecticides are pesticides specifically formulated to control insect pests that feed on crop plants and reduce yields.

Harvesting is the act of reaping mature crops when they are fully ripe and ready for consumption or processing.

A sickle is a curved hand tool with a sharp blade used by farmers to cut mature crops close to the ground during harvesting.

Threshing involves beating or mechanically separating edible grains from the straw and chaff after harvesting.

Winnowing uses air currents to separate lighter husks and chaff from heavier grains, often done after threshing.

A winnowing basket is a shallow, woven tray used to toss the grain mixture so that wind blows away the lighter chaff.

Proper storage prevents losses due to insects, rodents, fungi, and moisture, ensuring food availability for longer periods.

In rural areas, grains are often stored in gunny bags or traditional mud bins that are lined with straw and kept in dry, ventilated places.

Silos are tall, cylindrical structures that provide controlled conditions for storing large quantities of grains safely for long periods.

Plant breeding involves selecting and crossing plants with desirable characteristics to produce new varieties with higher yield, disease resistance, or better quality.

Through plant breeding, scientists create improved varieties that can resist specific pests or diseases, reducing the need for chemical pesticides.

Crop rotation helps prevent nutrient depletion, reduces pest buildup, and improves soil health by alternating crops with different nutrient requirements.

The Green Revolution introduced high-yielding varieties, chemical fertilizers, and modern irrigation techniques to significantly increase food grain production in India.

Early-maturing varieties shorten the growing period, enabling farmers to grow two or three crops on the same land within a year.

Kalyan Sona was one of the successful high-yielding wheat varieties introduced during the Green Revolution, contributing to increased wheat production.

Canal irrigation is a large-scale system where water is diverted from rivers or reservoirs through a network of canals to agricultural fields.

Fungicides are pesticides that kill or inhibit the growth of fungi that cause diseases like rust, blight, and mildew in crops.

Mixed cropping, such as growing wheat with gram, reduces the risk of crop failure and provides diversity in yield.

Seed treatment protects seeds from soil-borne diseases and pests, while quality selection ensures high germination rates.

Transplanting allows young seedlings to be nurtured in a controlled nursery environment before being moved to the main field.

Sprinkler systems can be used on uneven terrain and sandy soils where flood irrigation would be inefficient due to rapid water loss.

Proper fertilizer management ensures that crops receive the right nutrients at the right growth stages, preventing wastage and environmental harm.

Hoeing involves using a hand tool called a hoe to loosen soil, remove shallow weeds, and improve aeration around crop plants.

Organic manure enhances soil texture, water retention, and beneficial microbial activity, contributing to sustainable soil health.

Healthy seeds are dense and sink in water, while damaged or hollow seeds float and are discarded to ensure better germination.

Crop protection measures safeguard crops from various threats, ensuring higher yields and better quality produce.

Biological pest control uses natural enemies such as ladybirds, which feed on aphids, to control pests without harmful chemicals.

Sun drying reduces the moisture content of grains, preventing the growth of molds and fungi during storage.

Leguminous crops have root nodules with nitrogen-fixing bacteria that enrich the soil with nitrogen, benefiting the subsequent cereal crop.

A seed drill sows seeds at uniform depth and spacing, ensuring even germination, better growth, and efficient use of seeds.

Many vegetables and paddy rice are grown by transplanting because it allows better spacing and stronger establishment.

Drip irrigation uses emitters to release water slowly at the root zone, minimizing evaporation and water wastage.

Weeds compete with crops for water, nutrients, and sunlight; removing them allows the main crop to thrive and produce higher yields.

A combine harvester cuts the crop and separates the grains from the stalks in a single operation, saving time and labor.

Plant breeding aims to create improved crop varieties that produce higher yields, resist diseases, and adapt to different environmental conditions.

Airtight storage prevents entry of pests and protects grains from humidity, which can cause spoilage and reduce storage life.
