Irrigation

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: -

A comprehensive set of presentations and papers from the "South Asia Conference on Outstanding Organic Agriculture Techniques" held at Bangalore, Karnataka on 10 and 11 September 2009, and organised by the Organic Farming Association of India (OFAI), National Center of Organic Farming (NCOF) and the Third World Network, Malaysia, covering various aspects of organic, natural and sustainable agriculture, is now available on the India Water Portal.

 The objectives of the study included: i) assessing the application of a common method for measuring irrigation subsidies in order to develop accurate, replicable and reliable subsidy estimates and ii) providing policy advice aimed at improving and standardizing the reporting of data on irrigation subsidies. 

This set of presentations from the conference on Outstanding Organic Agriculture Techniques held during September 2009 at Bangalore deals with the conservation of seeds particularly for small subsistence farmers who are not very well linked with local markets and for whom seed production is still an integral part of farming activity seamlessly merged with the growing of crops and the totality of work and life on a farm.
