1. Agriculture is the predominant user (75-80%) of the available freshwater resource in many parts of the world. At present most of the water used to grow crops is derived from rainfed soil moisture, with non-irrigated agriculture accounting for some 60% of production in developing countries. Although irrigation provides only 10% of agricultural water use and covers just around 20% of the cropl...

Water is one of the very important inputs necessary for production food crops hence, security and rural livelihoods are essentially linked to accessibility water. Eighty percent world’s global agricultural land area under rain-fed; this contributes 58% staple foods. In Sub-Sahara Africa (SSA), reliance on rain-fed agriculture high with 97% moisture needs fulfilled mainly by water stored i...

With uncertainty in future irrigation water availability and regulations on nutrient application amounts, experimentally determined effects of “controllable” management strategies such as nitrogen (N), water, and their combination on crop water productivity (CWP, also known as crop water use efficiency) and actual evapotranspiration (ETa) are essential. The effects of various N application rate...

Rainfed lowland rice ecosystem is affected not only by water deficit but also by excess water leading from partial to complete submergence. Although the rice plant is well adapted to aquatic environment, it is unable to survive if completely submerged in water for several weeks. Damage to rice plants due to excess water has been advocated to occur during submergence and also on entry of oxygen ...

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...

Rice is the most important human food crop in world, directly feeding more people than any other crop. Tunga Bhadra Project (TBP) command area called as bowl of Karnataka. The study was conducted Shivamogga district Karnataka, India during 2020-21 mainly for economic analysis cost and returns rainfed paddy. A purposive sampling technique used selection area, Two taluks (Shikaripura Soraba) were...
