Sustainable use of natural resources for crop intensification and betterlivelihoods in the rainfed semi-arid tropics of Central India
tIn Indian semi-arid tropics (SAT) in general and central part i.e. Madhya Pradesh state specifically; thereare large yield gaps in most of the rainfed crops between current farmers’ yields and achievable ones.Soil fertility ...
Role of crop competition in managing weeds in rice, wheat, and maize in India: A review
In India, the three staple food crops viz., rice, wheat, and maize, contribute more than four-fifths of the
total food grain production. Among the several factors limiting their productivity, weeds account for
about 40%. ...
Long term effect of conservation agriculture in maize rotations on total organic carbon, physical and biological properties of a sandy loam soil in north-western Indo- Gangetic Plains
Maize-based crop rotations are advocated as alternate to rice-based systems in South Asia due to better suitability for diverse ecologies, higher yields with less water use and more palatable maize fodder compared to rice, ...
Selection of Hyperspectral Narrowbands (HNBs) and Composition of Hyperspectral Twoband Vegetation Indices (HVIs) for Biophysical Characterization and Discrimination of Crop Types Using Field Re ectance and Hyperion/EO-1 Data
The overarching goal of this study was to establish
optimal hyperspectral vegetation indices (HVIs) and hyperspectral
narrowbands (HNBs) that best characterize, classify, model,
and map the world’s main agricultural crops. ...
Individual and combined effects of transient drought and heat stress on carbon assimilation and seed filling in chickpea
High temperatures and decreased rainfall are detrimental to yield in chickpea (Cicer arietinum L.), particularly
during grain filling. This study aimed to (i) assess the individual and combined effects of drought and heat ...
Need to strengthen analytical support in agricultural research
The need for analytical support in agricultural
research has long been recognized,
especially in the context of soil
fertility evaluation and nutrient management,
and crop quality assessment and
monitoring for selecting ...
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 ...
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 ...
Biological nitrification inhibition in sorghum: the role of sorgoleone production
Background and aims Nitrification and denitrification
are the two most important processes that contribute to
greenhouse gas emission and inefficient use of nitrogen.
Suppressing soil nitrification through the release of ...
