Increased arid and semi-arid areas in India with associated shifts during 1971-2004
Climate change is one of the major challenges in 21st century faced by Agriculture in India, more
so in the Semi-Arid Tropics (SAT) of the country. In recent years, natural and anthropogenic factors have
impacted climate ...
Molybdenum status and critical limit in the soil for green gram (Vigna radiata) growing in Madurai and Sivagangai districts of Tamil Nadu, India
A survey was undertaken during 2008 to determine molybdenum (Mo) status of soils and to establish critical
limits in soils of Madurai and Sivagangai districts of Tamil Nadu. A total of 202 surface soil samples were
collected ...
Inter-row tillage for improved soil and water conservation and crop yields on crusted Alfisols
In the semi-arid tropics (SAT), 33% areas are oc- cupied by Alfisols and related soils. In SAT these soils have low structural stability and thereby tend to form seal and crusts at the surface. Due to this a large proportion ...
Diffuse Reflectance Spectroscopic Approach for the Characterization of Soil Aggregate Size Distribution
Assessment of soil structure and soil aggregation remains a challenging task.
Routine methods such as dry- and wet-sieving approaches are generally time
consuming and tedious, which calls for a robust, fast, and ...
Red ferruginous soils of tropical Indian environments: A review of the pedogenic processes and its implications for edaphology
Red ferruginous (RF) soils of tropical Indian environments belong to Entisols, Inceptisols, Alfisols, Mollisols and
Ultisols soil orders. The occurrence of Ultisols alongside acidic Alfisols and Mollisols in both zeolitic ...
Comparative evaluation of protein content in groundnut samples by near infrared reflectance spectroscopy and Skalar colorimetric methods
A lot of research has been done in developing groundnut cultivars with highquality
oil. As a result, methods for routinely determining oil
content and quality have been developed and utilized. However, groundnut is also a ...
Soil test-based nutrient balancing improved crop productivity and rural livelihoods: case study from rainfed semi-arid tropics in Andhra Pradesh, India
Widespread multinutrient deficiencies in the semi-arid tropics (SAT) are among major factors for large gaps between farmers’ current crop yields and potential yields. In this study, we adopted stratified soil sampling ...
Water requirement and use by Jatropha curcas in a semi-arid tropical location
Increasing emphasis on biofuel to meet the growing energy demand while reducing
emissions of greenhouse gases, Jatropha curcas has attracted the attention of researchers,
policy makers and industries as a good candidate ...
Rhizobacterial-plant interactions: Strategies ensuring plant growth promotion under drought and salinity stress
Drought and salinity are major environmental stresses resulting in secondary stresses such as osmotic
and oxidative stress (common to both stresses) as well as ionic stress (during salinity) causing alterations
in ...
Managing soil fertility constraints in market-led shift to high value agriculture for benefiting smallholders in the semi-arid tropics
Low productivity and cultivation of low value crops in
the Indian semi-arid tropics (SAT) is the main cause for
poor farm-based livelihoods. Poverty leading to low risktaking
ability of farmers and production related
constraints ...
