The livestock production system is considered equally sensitive to climate change as that of core agriculture system and at the same time livestock itself is also contributing to the phenomenon. The present paper attempts to analyze the sensitivity of livestock productivity in rainfed regions to climatic variability, significance of climate change with respect to Indian livestock and mitigation...
Groundnut (Arachis hypogaea L.) is an important oilseed crop grown in our country. Majority of crop is under rainfed conditions and as a post rainy season (Rabi) crop in Andhra Pradesh. Several models are available to predict the phenology, growth and yield of groundnut crop. However, no precise models are available to validate the effects of moisture stress on groundnut and their subsequent im...
We assessed the potential profitability of twin-row (TR) planting geometry as a water productivity-enhancing practice and skip-row irrigation (SRI) water-conserving in furrow-irrigated cotton (Gossypium hirsutum L.) soybean (Glycine max L.). Data from agronomic experiments carried on Dundee silt loam soils indicate that, average, TR increases by US$344 ha?1 for all-row irrigated (ARI), $401 SRI...
Farmers have to make decisions adapt climate change and reduce environmental vulnerability. If these are made incorrectly, irreversible changes can take place that threaten environmental, social economic sustainability of agriculture. This study applies a land use model guide regional agricultural planning, with focus on the case south basin Urmia Lake, NW Iran, using data from Landsat images, ...
Rotations and associated management practices in rainfed farming systems of southwest Australia have shifted towards intensified cropping. Survey data from 184 fields spanning 14 Mha were used to document water use efficiency (WUE) water-limited yield potential (WLYP) commercial crops crop sequences identify biophysical variables influencing WUE. WUE achieved wheat was 10.7 kg grain/ha.mm. Usin...
The overarching goal of this research was to develop and demonstrate an automated Cropland Classification Algorithm (ACCA) that will rapidly, routinely, and accurately classify agricultural cropland extent, areas, and characteristics (e.g., irrigated vs. rainfed) over large areas such as a country or a region through combination of multi-sensor remote sensing and secondary data. In this researc...
The quality of grains and flour can be influenced by genetics, crop management, environment. objective this study was to evaluate the technological wheat interaction among genotype, nitrogen (N) fertilization weather conditions in different regions adaptation southern Brazil, aiming support farmers bakery industry sector their decision-making processes. experiment carried out three environments...
water deficit is an important factor limiting crop growth all over the world. in order to evaluate genetic variation, heritability and the interrelationship between agronomic traits, twenty chickpea genotypes were cultivated in two separated randomized complete block experiments with three replications under normal irrigated and rainfed conditions. the experiments were carried out at the agricu...
poor wheat stand establishment is a major cause of yield loss, particularly in rainfed and poorly irrigated environments. seeds of eight wheat cultivars (triticum aestivum l.) including irrigated and rainfed varieties, belonging to three different climates of iran (hamedan as cold, karaj as temperate and sarpolzohab as warm climates) were primed using osmoprimig treatments through use of urea ,...
