Low External Input Sustainable Agriculture (LEISA)

Interventions that make agriculture sustainably high-yielding, eco-friendly and empower small-holder farmers - A research paper (2009)

This paper discusses agricultural techniques that rely on non-chemical methods  that enhance crop productivity. 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.Read More

Comparing conventional and organic farming crop production systems - Inputs, minimal treatments and data needs - A research paper

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.

The researchers here discuss the experiences gained from this experiment and those gathered from organic farmers. Further, the authors offer suggestions for future demonstration and verification experiments, to study the virtues of organic  farming.Read More

Lessons from non-chemical input treatments based on scientific and traditional knowledge in a long-term farming experiment - A research paper

This paper reports on a field experiment conducted at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in Patancheru, where four crop-husbandry systems were studied.

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.Read More

Evaluation of crop production systems based on locally available biological inputs - A research paper (2006)

This paper, part of a larger book 'Biological approaches to sustainable soil systems', reports the results of a field experiment, conducted in Patancheru, Andhra Pradesh, where 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.Read More
