Warming temperatures cause temporal changes in growing seasons and prey abundance that drive earlier breeding by birds, especially dietary specialists within homogeneous habitat. Less is known about how generalists respond to climate-associated shifts in growing seasons or prey phenology, which may occur at different rates across land cover types. We studied whether breeding phenology of a gene...
dry drainage could be considered as a natural system which evaporates water from fallow areas to control water table depth and soil salinity in neighboring cropped area. the technique requires the retirement of part of the irrigated land. one of the most notable design criteria for this system is to estimate the ratio of cropped to fallow strip width. a plexiglas physical model with the dimensi...
The objective of the experiment was to develop cropping sequence modules for round year green fodder production feeding 50 dairy cattle under irrigated conditions in North-West Himalayan region. Various were initiated at Research Farm Instructional Livestock Centre, R.S. Pura, FVSc. & A.H., SKUAST-Jammu during 2016 an area 2.5 ha. experimental data collected after fully establishing unit 20...
Time series data on cropping pattern at disaggregated level were analysed and its implications on geospatial drought assessment were demonstrated. An index of Cropping Pattern Dissimilarity (CP-DI) between a pair of years, developed in this study, proved that the cropping pattern of a year has a higher degree of similarity with that of recent past years only and tends to be dissimilar with long...
