Answer:
The introduction of High Yielding Varieties (HYV) of seeds and the increased use of chemical fertilisers and irrigation are known collectively as Green Revolution. It provided the increase in production needed to make India self-sufficient in foodgrains, thus improved the agricultural sector in India. High yielding wheat was first introduced to India in 1968 by American agronomist Norman Borlaug. Borlaug has been hailed as father of Green Revolution, but MS Swaminathan is known as 'Father of Green Revolution in India'.. Thus, Green Revolution is the term used to describe a new strategy of agricultural development introduced in the late 1960s, in India. It brought about significant increase in food production in India.
The main features of Green Revolution in India were as follows
(i) High Yielding Varieties seeds promised to produce much greater amounts of grain on a single plant.
(ii) Use of advanced technology, chemical fertilisers, pesticides and well-developed system of irrigation.
(iii) These steps solved food crisis in India and made India self-sufficient in foodgrains.
(iv) This led to higher income growth and reduced poverty.
(v) This led to commercialisation of agriculture. In many areas, Green Revolution is associated with loss of soil fertility due to increased use of chemical fertilisers. Also, continuous use of groundwater for tubewell irrigation has reduced the water level below the ground.
Cropping patterns
To improve the yield of crops by complete utilization of nutrients and prevent pest control, we should use different cropping patterns which are as follows :
(i) Mixed cropping
It refers to the sowing of two or more different crops together in the same field, e.g., wheat and gram. Wheat crops decrease the fertility of soil on the other hand gram crops support it by fixing atmospheric nitrogen with the help of nitrogen fixing bacteria. By this way of cropping we can save time and labour and improve the fertility of soil. Some of the mixed cropping practices are wheat-mustard, millet + cowpea, cotton + mungbean.
(ii) Intercropping
It is growing of two or more crop simultaneously on the same field in a definite row pattern. It means few rows of one crop and adjoining to that few rows of another crop. By this way of cropping, we may get better yield of both crop e.g., soyabean + maize.
(iii) Crop rotation
If the same crop is grown every year in the same field, then the fertility of the soil decreases. To avoid this situation, we use crop rotation. It stores the fertility of the soil. So crop rotation is the process of growing two or more types of crops alternately in the same field. Based on duration, crop rotation is applied for various crop combination.
Rice bean, oat, barley
are some fodder crops
The sustainable agriculture is the techniques which do not disturb the nature balance.
The sustainable agriculture can be defined as a farming technique which is sustained without hampering land or environment or the condition of the people. It is very profitable, socially supportive and ecologically beneficial.
The sustainable agriculture is the agriculture which is economically balanced, socially responsible and ecologically good. These qualities are very much important for balancing in the nature.
