Effect of integrated rainwater-management practices on soil properties and productivity of groundnut (Arachis hypogaea) in arid and semi-arid regions of Andhra Pradesh

A field experiment was conducted during the rainy season (kharif) of 2017 and 2018 at Agricultural Research Station Acharya N.G. Ranga University, Ananthapuramu, Andhra Pradesh, to study effect integrated rainwater-management practices on soil properties groundnut (Arachis hypogaea L.) productivity. The laid out in a randomized block design with 9 3 replications. Results indicated that, application shales @ 300 t/ha as surface mulch combined 2 supplemental irrigations 10 mm each when dryspell days occurs after 50% flowering treatment (T7 ) increased porosity, water holding capacity, infiltration rate by 17.8, 41.2 24.6%, respectively, bulk density reduced 5.0% compared dryland (T1 ). Similarly, same enhanced pod yield 39.68% control (T1). Thus, proved best practice improve increase productivity under arid semi-arid regions Pradesh.
