Abstract: The study was carried on the Nitrogen management strategies to improve growth and yield of cashew at Regional Horticultural Research and Extension Centre, University of Horticultural Sciences Campus, GKVK, Bengaluru during the years 2016-17, 2017-18 and 2018-19. The factorial randomized complete block design consisting of twelve treatments and three replications to know the comparative efficacy of nitrogenous fertilizers and their levels on growth and yield of cashew. The growth parameters like trunk girth and canopy spread decreased with increase in levels of nitrogen while plant height increased. However, the flowering laterals were maximum and cashew nut yield per plant was higher in100% RDN level. Among the sources, N applied through 25% FYM + 75% urea (8.48 kg plant-1) followed by 100% RDN through Calcium ammonium nitrate (CAN) produced higher yields (8.32 kg plant-1). In interaction of levels and sources, 100% RDN through CAN was found to be superior (8.38 kg plant-1) followed by 100% RDN through vermicompost (8.24 kg plant-1) compared to other sources of combination.
