An assessment of crop water productivity in the Indus and Ganges river basins: Current status and scope for improvement – A research report by IWMI

IWMI ReportThis paper by the International Water Management Institute (IWMI) presents a new approach for analysis of water productivity (WP) of rice and wheat in the Indus and the Ganges river basins, South Asia, based on the integration of readily available remote sensing, national crop productivity and land use statistics and weather data. Understanding crop water productivity over large river basins has significant implications for sustainable basin development planning.  

Three major steps are involved in producing crop water productivity maps: (1) crop dominance map, (2) yield estimates, and (3) water consumption (evapotranspiration (ET)) estimates. The crop dominance map is synthesized from the relevant, and publically available, land use/land cover (LULC) maps with ground truth data. National statistics on crop area and yields are collected, and the yields are interpolated to grid level (500 meters (m) x 500 m) using Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) maps.

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

Comparing soil properties of farmers’ fields growing rice through SRI and conventional methods - A research paper

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

Organic farming and food security - A model for India - A paper by Society for Organic Agriculture Movement

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.Read More

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.

Interpolation of groundwater levels using kriging in Sagar district – A research report by National Institute of Hydrology

In this report, an application of kriging technique is presented for interpolation of groundwater levels in Sagar district of Madhya Pradesh. Groundwater management is important to meet the increasing demand for domestic, agricultural and industrial use. Various management measures need to know the spatial and temporal behavior of groundwater. Most of the groundwater models require the inputs to be available on a grid pattern. However in the field, these parameters are generally measured at random points. However, interpolation of parameters at the grid nodes is a prerequisite for using this data in groundwater modeling.Read More

Spectral response of rice plant canopy – A research report by National Institute of Hydrology

The study was conducted with the objective of establishing the relationship between spectral reflectance of rice canopy and crop growth. Significant relationship was developed between spectral indices and growth period. The coefficient of correlation between crop growth period and spectral reflectance ranged from 0.41 to 0.97 for the plant growth stages and canopy reflectance in single band and ratio spectra.Read More
