New Delhi: Farmers in India have taken intelligent decisions by shifting of sowing pattern frequently suiting to the climatic condition and requirement of the nation. But such decisions by farmers depends heavily in rainfalls during the Kharif sowing season and cold waves in the winter season. The intensity of these two natural occurrences determines sowing and availability of agriculture crops in India.
Yet the farmers want sustainable crop pattern for their own future planning. Long time continuation of one crop by a group or a region specific farmers help them do proper planning of sowing, plant care, harvesting and selling of their agri output.
According to research done by The International Assessment of Agricultural Science and Technology for Development [IAASTD], an initiative of the United Nations and World Bank, if a solution is to be found for the current crisis in the agriculture sector, the way forward is to encourage small-scale farmlands and sustainable agricultural methods. Even in India, agriculturists like Subhash Palekar have demonstrated that natural and traditional farming methods can help crops flourish.
“Sustainable agriculture help farmers plan their crop pattern, sowing of seed, irrigation and moisture related decisions, harvesting and selling their produce. Better planning would help achieve better domestic realisation and export growth to fetch higher prices. Today, farmers plan their seed sowing depending upon the market condition of the respective output two years ago. A sustainable agriculture would help them plan entire agricultural needs including science and technology well in advance to achieve higher output and double their income as the Prime Minister Narendra Modi envisages to achieve by 2022,” said S Ganesan, Vice President, UPL Ltd.
Sustainable agriculture requires eco-friendly agricultural practices to be used. Special attention to conservation of the environment as well as to crop yield is crucial; hence the use of mechanization, fertilizers, pesticides, etc. had to be controlled.
Experts also said that sustainable agriculture would also help reduce farmers’ suicide automatically with improvement in their loan repayment capacity.
Some of the sustainable agricultural practices are:
Conservation of local land crop varieties over hybrid high yielding varieties.‘ Desi’ (local) variants not only maintain crop diversity but also have useful genetic traits like resistance to disease, pest and droughts as well as nutritive value specific to the area which can benefit future crop improvement programs.
Conservation of water and watershed management. Not all regions get sufficient rainfall for growing crops. Hence rainfall and irrigation management techniques like water harvesting and evapotranspiration are implemented. These help reduce water logging and salinity. Water-shedding helps optimize usage of land, water and crops.
Adopting tillage conservation methods that involve disturbing the top soil level to the bare minimum and leaving crop residues in the soil. This helps maintain the biological activity, organic and nutrient matter of the soil.
Use of natural compost, manure and animal waste, which can revive the fertility and nutrient value of the soil, as well as protect the useful flora and fauna in the soil.
Weed and Pest management is another important sustainable measure. Weeds help control crop diseases and pests, conservation of soil and moisture, and nutrient cycling. Hence in sustainable agriculture, weeds are tolerated and encouraged up to a certain extent.
Another important step introduced is the age-old practice of crop diversification. Crop rotation, mixed cropping and intensive cropping are some of the methods implemented to enhance yield but also reduce the soil erosion.
