Research Papers

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.

This paper was presented at the first National Symposium on System of Rice Intensification (SRI) – Present Status and Future Prospects held in 2006.  The parameters include thirteen soil properties which included six related to cultureable microorganisms, three root-related parameters and yield.

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 paper in the Indian Journal of Traditional Knowledge aims to describe indigenous pest management (IPM) practices being followed by farmers of Bageshwar district of Uttarakhand and their belief behind following them.With those practices, farmers would manage pests effectively without deteriorating environment. These practices could be very important if incorporated into integrated pest management research to enrich the research process and make it more relevant for the farmers. 

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.

This study by National Environmental Engineering Research Institute published in Current Science was carried out to identify Pteris vitta and test its hyper-accumulating properties. The plant is commonly known as the Ladder brake fern or Chinese brake fern plant in India, and had been reported elsewhere as an arsenic hyper-accumulator.

.The remediation of arsenic and chromium contaminated soil and water has become an important environmental issue. It is in this context that the discovery of hyper-accumulator plant species, which have the unusual ability of accumulating metals such as arsenic (As), chromium (Cr), zinc (Zn), nickel (Ni) and copper (Cu) to very high concentrations, has further boosted technologies based on this property.

This is the first report of characterization of arsenic accumulation in an Indian ecotype (plant), which also shows chromium hyperaccumulation in addition to arsenic. Intact plantlets were grown in 20 per cent Hoagland solution amended with up to 200 mg arsenic or chromium medium. Plants absorbed and accumulated a significant amount of arsenic and chromium in their biomass with high bio-enrichment factor. Arsenic and chromium tolerance by spores and gametophytes under in-vitro was also assessed.

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.

 Plasmid-encoding Carbapenemase-resistant Metallo-B-Lactamase (PCM or NDM-1) is an enzyme that makes bacteria resistant, not only to a broad range of antibiotics such as carbapenems and other β-lactam, but also to multiple other antibiotic classes, leaving very few treatment options available, when a person gets infected with such bacteria.

After 3 decades of relentless fighting for rehabilitation, 113 tribal families displaced by Sardar Sarovar Dam on the River Narmada in India’s Madhya Pradesh have finally had their demand fulfilled. The families have received land on which they can now build their homes again. Rakesh says that the development has raised the hopes of thousands of others like him who are still awaiting resettlement.

This paper discusses the need to shift from chemical intensive agriculture to organic farming. The authors in their vision for a chemical-free agriculture also stress that organic agriculture is a way to achieve food security.

The authors begin with the current crisis in Indian agriculture. Stating that though the Green Revolution made India self-sufficient in food production in the shortest time it also resulted in a host of problems. The indiscriminate use of fertilizers, insecticides, fungicides and herbicides has created problems of decline in the soil fertility, pollution of water resources, and chemical contamination of food grains, amongst the many similar issues now linked to the Green Revolution.
