Abstract
A field experiment was conducted during the winter months (October-February) of 2022-23 at the Instructionalcum Research Farm of Assam Agricultural University, Jorhat to assess the effect of different irrigation scheduling practices along with nano urea on growth and productivity of rabi maize.The experiment was laid out in split-plot design with four distinct irrigation schedules and three varied nitrogen management practices under main plot and sub plot treatments.Results revealed that relatively all growth parameters, yield attributing characters, cob, kernel and stover yield were higher under irrigation at grand growth period, tasseling and grain filling stages being statistically at par with irrigation at 0.8 IW/CPE ratio.Contrarily, 50% recommended doses of nitrogen (RDN) through urea as basal + 6 ml/litre nano urea at knee high and tasseling stage being at par with 50% RDN through urea as basal + 4 ml/litre nano urea at knee high and tasseling stage recorded significantly highest cob, kernel and stover yield over recommended doses of fertilizers (RDF) + water spray at knee high and tasseling stage.Interaction effect was observed for kernel weight/cob, kernel and stover yield.However, lowest growth, yield parameters and yield were observed under rainfed and 0.6 IW/CPE of irrigation scheduling.
