Approximately 7,600 wheat plots were surveyed and geo-tagged in the 2017-18 winter or rabi season in Bihar and eastern Uttar Pradesh (UP) in India to capture farmers’ wheat production practices at the landscape level. A two-stage cluster sampling method, based on Census data and electoral rolls, was used to identify 210 wheat farmers in each of 40 districts. The survey, implemented in Open Data Kit (ODK), recorded 226 variables covering major crop production factors such as previous crop, residue management, crop establishment method, variety and seed sources, nutrient management, irrigation management, weed flora and their management, harvesting method and farmer reported yield. Crop cuts were also made in 10% of fields. Data were very carefully checked with enumerators. These data should be very useful for technology targeting, yield prediction and other spatial analyses.

Abstract

In this rising of the world because of more interest of normally accessible growing materials for the need of modification of development material. Concrete is of growing importance than any other building material on the planet. Because of the increase in population, the volume and kind of waste materials in the globe is increasing every day. As a result, many more non-perishable materials are available in the environment. The DC waste materials have extended due to disposal extremity in the world and thereby contributing to the environmental problems. Demolition is a term that is used to describe the act of demolishing anything. Construction waste materials have indeed been disposed of in concrete safely and cost-effectively. The use of DC waste materials as a partial replacement for fine aggregates in the creation of ecologically friendly concrete is proposed in this study.
