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 ...
Production technologies for enhancing sweet sorghum yields
Adoption of good crop and soil management practices are important for maximum productivity and to make the system sustainable in
the long run. This chapter describes the cultivars and good cultural practices that are to ...
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 ...
CALIBRATING CHLOROPHYLL METER (SPAD-502) READING BY SPECIFIC LEAF AREA FOR ESTIMATING LEAF NITROGEN CONCENTRATION IN SWEET SORGHUM
The chlorophyll meter (SPAD-502) is used to estimate nitrogen status of various crops. However,
the relationship between SPAD readings and leaf nitrogen concentration (LNC) in sweet sorghum
(Sorghum bicolor) has not been ...
Soil Testing as a Tool for On-Farm Fertility Management: Experience from the Semi-arid Zone of India
Rainfed agriculture in the dry regions is affected by water shortages. Our earlier
research showed that the deficiencies not only of major nutrients but also those of sulfur
(S) and micronutrients are holding back the ...
