Rainfed Agriculture

 Stating that modern agriculture increases production cost, the author observes that productivity of the same crop was higher in pre-British times than what it is now with modern agriculture techniques.

As these old agricultural techniques have not been scientifically researched there is a lot of scepticism which also results in them not being promoted. The paper lists out agricultural techniques, which result in sustainable high yields and are accepted by the scientific community.

The following article is based on a field experiment in International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), where low cost farming systems that involve use of biological inputs obtained from the field is compared with conventional farming.

Further, the authors offer suggestions for future demonstration and verification experiments, to study the virtues of organic  farming.

Two of the four systems are low-cost farming methods which are based on traditional and scientific knowledge on using crop residues, farm-waste, compost, Gliricidia lopping, bacterial inoculants, and herbal extracts as nutrients to nourish the soil, and as biopesticides to manage pests.

The third system is conventional agriculture which is the "control" and receives chemical input as suggested by research institutions depending on crop type. The fourth is a combination of the  first three.

This  brings together the results of formal research on SRI in a number of countries (Part I) and also reports on initiatives by government agencies, NGOs, universities, or the private sector, bringing knowledge of SRI to farmers in a wide range of agroecological circumstances (Part II). It has six articles and nine technical reports from Afghanistan, China, the Gambia, Kenya, India, Indonesia, Iraq, Mali,  Pakistan, Panama, and Thailand as well as several review articles.

The System of Rice Intensification (SRI), developed in Madagascar almost 30 years ago, modifies certain practices for managing plants, soil, water, and nutrients with the effect of raising the productivity of the land, labor, and capital devoted to rice production. Certain production inputs are reduced—seeds, inorganic fertilizer, water, and fuel where water is pumped—with increased yield as a result.

Here the yields of crops grown by low-cost inputs including plant biomass are compared with chemical fertiliser-induced production.

The study was conducted over 1999-2004, and the findings conclude that the yields of low intensive biological farming are as good, if not better than chemical fertiliser intensive farming.

A summary of major recommendations of Working Group are as follows: -
