Abstract
An experiment was conducted at Student’s “Instructional farm of Acharya Narendra Deva University of Agriculture and Technology Kumarganj, Ayodhya (U.P.) during rabi season 2019-2020. The experiment was laid out in split plot design (SPD) with three replications using the wheat variety HD- 2967. The treatments comprised of four levels of irrigation viz. 0.6 IW/CPE ratio (I1), 0.8 IW/CPE ratio (I2), 1.0 IW/CPE ratio (I3), 1.2 IW/CPE ratio (I4), and three nitrogen sources viz. 100% (RDF) through urea (N1), 50% RDF + 50% FYM (N2), 50% RDF + 50% poultry manure (N3).The build-up in organic carbon was found with the application of moisture regime at 1.2 IW/CPE and the minimum was received with the moisture regime at 0.6 IW/CPE during the investigation. The increment level of available nitrogen, phosphorus, potassium and zinc were found with the increasing level of moisture regime. The maximum was found with the application of moisture regime at 1.2 IW/CPE and the minimum was received with the moisture regime at 0.6 IW/CPE during the investigation. Moisture regimes 1.2 IW/CPE ratio was found best for viz., pH , EC and organic carbon, Available Nitrogen, Phosphorus , Potassium & Zinc and among the Nitrogen level, application of 50% N from urea + 50% N from Poultry manure (N3) was found suitable for soil fertility status followed by 50% N from urea +50% N from FYM (N2)
Keywords: Wheat, moisture regime, nitrogen sources, soil fertility
