Modelling Trends in Streamflow and Groundwater Storage in an Agricultural Basin: A Case Study of Himayat Sagar Catchment, India
The most visible signs of hydrologic change in a catchment can be observed from trends in streamflow and groundwater levels. Increasing irrigation and associated groundwater extraction, as well as interception of runoff ...
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 ...
Comparative Evaluation of Inductively Coupled Plasma–Atomic Emission Spectroscopy and Colorimetric Methods for Determining Hot-Water-Extractable Boron in Soils
Boron (B) deficiency frequency is increasing in rainfed systems and hence the need to diagnose the deficiency. Colorimetric methods are still widely used in soil testing laboratories in India for measuring B. Little ...
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 ...
Soil and water management
Soil and water form the basis of all terrestrial life. Their resources vary widely and are affected by natural and anthropogenic
perturbations. Ancient civilizations and cultures emerged and sustained on good soils; and ...
Conservation agriculture for improving water productivity in Vertisols of semi-arid tropics
Large variability and uncertainty of rainfall are the
main limiting factors for crop growth in rainfed agriculture.
Agriculture water management interventions
are considered as suitable adoption strategy to enhance
crop ...
