Increasing use of fertilisers has led to a phenomenal growth in the food grain production over the last four decades. However, the pattern of fertiliser use varies widely from state to state. There is a need for balanced and integrated use of plant nutrients to ensure food security to the population in future.
The increased use of chemical fertilizers in India came with the advent of Green Revolution in the 1960s. Introduction of fertilisers helped greatly to increase the food production in the country in a time when the agricultural sector was failing - as a repercussion to natural disasters. However, the continuum of the large scale usage is raising concerns about judiciousness and efficacy of chemical fertilisers in the present context.
The Indian agricultural scenario is experiencing a series of changes since the green revolution. Here is a brief essay that outlines concepts of how agricultural calculations are undertaken - agricultural productivity and efficiency, crop combination, degree of commercialisation, diffusion of innovation and more, to help comprehend the agricultural scenario with lucidity.
Agriculture credit is a loan or extension of credit provided by a bank for agricultural or allied rural use – one of the most crucial inputs for agricultural development.
With the onslaught of green revolution and now the advent of genetically modified species, traditional seed culture practices are slowly but surely dying-out. India’s vast biodiversity in terms of indigenous agricultural landraces require to be revived to ensure conservation and ultimately food security.
Genetic Modification is a process by which DNA of an organism can be altered to synthesise a new, usually better or more efficient version of the original organism. The breakthrough in science was initiated particularly in the field of agriculture, to improve crop protection through the use of one of the three basic traits: resistance to insect damage; resistance to viral infections; and tolerance towards herbicides. But, like all new technologies, GM crops also pose certain apprehensions and risks, both known and unknown.
The village of Dekheta in Orissa, was selected as a field research base by Central Rice Research Institute (CRRI), Cuttack, in 2008 just before the monsoons. The results were so encouraging that today the women here have organised themselves to create a flood-resistant paddy seed bank with technical help being offered by CRRI.
Apprehensions about climate change continue to rise, despite our limited ability to make precise assessments of its impact. This is partly due to the complexity of chemical and physical processes at various scales, and also due to confounding factors from other changes such as air pollution.
Rice is grown in range of eco-systems under varying climatic and hydrological conditions - from waterlogged, and irrigated to rainfed situations. Based on the levels of productivity, the status of rice across the nation has been classified under five categories, purposing analysis.
