Crop Water Requirement, Water Productivity and Comparative Advantage of Crop Production in Different Regions of Uttar Pradesh, India

Evaluation of Virtual Water and Water Footprint of Crop Production (Case study: Qaleganj County)

To address the optimal use of available water resources, a revisit of water resource allocation and management is needed. Water use and water footprint of every product varies in different geographical areas due to various climate, agricultural operations and water efficiencies. Thus, more productive management schemes are to be developed. The goal of this study is to assess the virtual water a...

Balanced plant nutrition enhances rainfed crop yields and water productivity in Jharkhand and Madhya Pradesh states of India

Two hundred and thirty six soil samples from farmers’ fields in the Gumla and Saraikela districts of Jharkhand, and Jhabua and Mandla districts of Madhya Pradesh were analyzed for soil chemical fertility. Results showed deficiencies of sulphur (43 to 100% of samples), boron (69 to 98%), and zinc (5 to 73%). Majority of the farmers’ fields, except for those in the Saraikela district, fell in the...

Improving water use in crop production.

Globally, agriculture accounts for 80-90% of all freshwater used by humans, and most of that is in crop production. In many areas, this water use is unsustainable; water supplies are also under pressure from other users and are being affected by climate change. Much effort is being made to reduce water use by crops and produce 'more crop per drop'. This paper examines water use by crops, taking...
