Agriculture and agricultural seasons

From daily life

The roti on your plate began as a wheat seed sown in a field months ago. Rain, soil and the farmer's work together made it grow.

Simple definition

We get food from plants. Crops grown from June to October are kharif (खरीप) crops, and crops grown from October to March are rabi (रब्बी) crops.

Rule 1: Agricultural seasons — Grains are sown in fields and fruit trees are planted in orchards. About 60% of our country's land is used for agriculture. In the kharif season (June to October) crops get water mainly from rain. In the rabi season (October to March) water comes from rain soaked into the soil, the retreating monsoon and dew. Crops grown from March to June are summer crops.

In the figure : In the figure kharif is June to October, rabi is October to March, and summer crops grow from March to June.

  • Easy : Easy: Kharif crops are sown with the rains in June.
  • Medium : Medium: The kharif season lasts 5 months (June to October).
  • Exam-type : Exam: The rabi season lasts 6 months (October to March).

Rule 2: Good harvest and farming then and now — A good harvest gives a good income. Fertile land, good seeds and fertilizers, and water are essential. In traditional farming oxen did the ploughing, a huge leather bag called mot pulled by oxen drew water from the well, and the farmer's family harvested and threshed. Now farmers use machines.

  • Easy : Easy: Oxen ploughed the fields earlier.
  • Medium : Medium: A mot drew water from the well.
  • Exam-type : Exam: Now machines do many farm jobs.
Remember

Kharif: June–October. Rabi: October–March. Summer: March–June.

Common mistake

Mixing up kharif and rabi. Kharif starts with the rains.

Improved seeds and modern irrigation

From daily life

Grandfather saved some grain from each harvest as seeds for the next year. Today scientists give farmers special seeds that give more grain.

Simple definition

Improved seeds (सुधारित बियाणे) give a higher yield. Drip irrigation (ठिबक सिंचन) and sprinkle irrigation (तुषार सिंचन) save water.

Rule 1: Improved seeds — Earlier, seeds from one harvest were kept for the next season, but their yield was not high. Today, research has produced improved seeds for crops like jowar, rice, groundnut and wheat. They give a higher yield, resist pests, some ripen sooner and some give a good yield even with little water.

  • Easy : Easy: Improved seeds give more grain.
  • Medium : Medium: Some improved seeds ripen in a shorter time.
  • Exam-type : Exam: Some improved seeds give a high yield with little water.

Rule 2: Saving water — Farmers use water from rivers, lakes and wells along with rain. Dams and bunds store more water and raise the groundwater level. Much canal water is lost by evaporation and seepage, so modern methods are used. In drip irrigation, pipes with holes drip water only near the plants. In sprinkle irrigation, sprinklers spray water over the plants. Both save a lot of water.

Drip irrigation: pipes with holes drip water at the roots. Sprinkle irrigation: a sprinkler sprays water on plantsTwo ways to save waterDrip irrigation🚰Pipes withholes💧Water dripsat the rootsSprinkle irrigation🚿Sprinkler🌦️Spray fallson plants

In the figure : In the figure both methods give water only where it is needed, so a lot of water is saved.

  • Easy : Easy: Drip irrigation uses pipes with holes.
  • Medium : Medium: Sprinklers spray water on the plants.
  • Exam-type : Exam: Canals lose water by evaporation and seepage, so drip or sprinkle methods are better.
Remember

Improved seeds = more yield. Drip and sprinkle = save water.

Common mistake

Mixing up drip and sprinkle. Drip = drops near roots; sprinkle = spray from above.

Fertilizers, organic farming and protection of crops

From daily life

If you eat the same sweet every day, you get bored. The soil also gets tired if the same crop is grown again and again, so farmers must feed the soil.

Simple definition

Fertilizers (खते) add nutrients to the soil. Natural fertilizers are called manures (शेणखत इ.). Chemical fertilizers are mixtures of chemicals.

Rule 1: Fertilizers — Growing the same crop again and again lowers soil fertility, so fertilizers are added. Natural fertilizers (manures) come from green waste and animal dung. Chemical fertilizers are mixtures of chemical substances in specific proportions. Too much chemical fertilizer makes chemicals pile up in the soil and lowers its fertility.

Natural manure from green waste and dung; chemical fertilizer is a chemical mixture and too much of it harms the soilTwo kinds of fertilizerNatural (manure)🍂Green waste🐄Animal dungChemical🧪Chemical mixture⚠️Too much harmsthe soil

In the figure : In the figure natural fertilizers are manures; chemical fertilizers must not be overused.

  • Easy : Easy: Manure is a natural fertilizer.
  • Medium : Medium: Overusing chemical fertilizers lowers fertility.
  • Exam-type : Exam: Repeating the same crop lowers soil fertility.

Rule 2: Too much water, pests and organic farming — Overwatering makes land saline and fallow (क्षारयुक्त आणि पडीक), especially near dams and river banks, and restoring it is costly and slow. Insecticides and pesticides are sprayed, or chemicals are rubbed on seeds before sowing, to fight diseases and pests. Organic farming (सेंद्रिय शेती) uses natural materials such as plant and animal manure, fish and bone meal, animal excreta and decomposed remains. It keeps nutrients in the soil, and its organic pesticides do not harm those who eat the produce.

Plant and animal waste becomes manure, which makes the soil rich and gives safe foodOrganic farming♻️Plant and animalwaste🪱Turns intomanure🌱Healthy,rich soil🥗Safe foodto eat

In the figure : In the figure in organic farming the soil is fed with natural materials and the food stays safe to eat.

  • Easy : Easy: Organic farming uses natural manure.
  • Medium : Medium: Overwatering makes land saline.
  • Exam-type : Exam: Organic pesticides do not harm those who eat the produce.
Remember

Manure = natural fertilizer. Do not overuse chemical fertilizers or water.

Common mistake

Thinking more fertilizer always means more crop. Too much damages the soil.

Food storage

From daily life

Your mother keeps rice in a closed steel drum with a few neem leaves. She does this so that insects and moisture cannot spoil the grain.

Simple definition

Food storage (अन्नसाठवण) keeps grain safe for later use. Storage places must be dry and airy.

Rule 1: Storing grain — Grain is dried well in the sun, filled in sacks and stocked at home or in warehouses. Mice, rats and insects can spoil it, and in a closed damp place it catches fungus. So chemicals are sprayed at the storage place, neem leaves are mixed with the grain, and the store is kept dry and airy.

In the figure : In the figure dry grain with neem leaves in a dry, airy place stays safe from rats, insects and fungus.

  • Easy : Easy: Dry the grain in the sun first.
  • Medium : Medium: Neem leaves keep insects away.
  • Exam-type : Exam: Damp closed places give fungus to grain.

Rule 2: Storage in nature and warehouses — Ants, bees (honey in a honeycomb) and squirrels (seeds) store food. Onions and garlic (bulbs) and potatoes and ginger (tubers) store food in their stems, and radishes, sweet potatoes and beetroots store it in their roots. Extra foodgrain is kept in huge warehouses, to be used when floods, drought, a cyclone or hailstorm hit production, or when an earthquake displaces people.

Green Revolution and food security

From daily life

Before the 1960s India often needed to import grain. Today India grows enough to feed its people and even sells extra grain to other countries. This change is called the Green Revolution.

Simple definition

The Green Revolution (हरितक्रांती) was the huge rise in foodgrain production, brought about by scientists, science-spreading workers and farmers working together.

Rule 1: The Green Revolution — Our country is self-reliant in foodgrains and can export surplus grain. The tremendous increase in production came during the Green Revolution. The credit for the research on wheat and rice seeds goes to Dr M. S. Swaminathan. Earlier, after the Bengal famine of 1943 and the shortages of the early 1960s, India had depended on imported grain. Later, new high-yield seeds raised wheat production sharply.

Scientists and farmers work together, better seeds give more production, and surplus grain can be exportedThe Green Revolution🧑‍🔬Scientists andfarmers worktogether🌾Better wheatand rice seeds📈Productionrises a lot🚢Surplus graincan be exported

In the figure : In the figure the Green Revolution made our country self-reliant in foodgrains.

  • Easy : Easy: India can export surplus grain.
  • Medium : Medium: Dr Swaminathan worked on wheat and rice seeds.
  • Exam-type : Exam: The Green Revolution raised foodgrain production greatly.

Rule 2: Food security — Many countries have Food Security laws so that every person gets enough food. Our country made its Food Security Law in 2013, which helps fight malnutrition, starvation and deaths from hunger. A Fair Price shop shows the rationing (public distribution) system. Agricultural assistance centres, agricultural schools and exhibitions by Agricultural Produce Marketing Committees give farmers information on technology, irrigation, improved seeds, fertilizers, pesticides and weather forecasts.

  • Easy : Easy: The Food Security Law was made in 2013.
  • Medium : Medium: A Fair Price shop sells grain at a fair price under rationing.
  • Exam-type : Exam: Food security fights hunger, malnutrition and starvation.
Remember

Green Revolution: Dr M. S. Swaminathan, wheat and rice. Food Security Law: 2013.

Common mistake

Mixing up the Green Revolution with the Food Security Law. One increased production; the other ensures every person gets food.
