A STUDY OF CROP HUSBANDRY IN LAKHAOTI COMMAND

Abstract

A study of crop husbandry in Lakhaoti Command was undertaken during Kharif season 1991 with the principal objectives. - To record crop husbandry practices under different irrigation sources in the command. - To conduct irrigability, drainability and soil climatic surveys. - To assess the biomass productivity using weather parameters - To assess the dry matter production potential of the crops, and - To analyse the water related yield constraints of the crops in the command area. Principal crops of the kharif season of the command area were maize, sorghum (fodder), Pigeon-Pea (Arhar) and sugarcane. These crops were taken for studies, irrigated by four different sources of irrigation. The irrigation sources were, government tube wells, private tube wells, a combination of government and private tube wells, and canals, Three government tube well commands and three minor canal commands were selected for studies. Soil samplings from six soil profiles, one from each commands were taken fro every 30 cm depth upto 1.80 m soil depth to analyse the soils physical and chemical properties. Field experiments were conducted for studying the hydraulic conductivity, field capacity and infiltration characteristics in each commands. Permanent wilting point for each command soil was determined in laboutatory, subjecting the soil samples for 15 bar pressure with the help of, pressure membrane apparatus. On analysis it was found, that sbils,in all commands are uniform.
