Impact of various organic sources of nitrogen on growth, yield attribbutes and yield of scented rice (Oryza sativa L.) under irrigated conditions of Chhattisgarh plains

Abstract

A field experiment was conducted at Research cum Instructional Farm, IGKV, Raipur during kharif 2014 and 2015 to evaluate the impact of different organic sources of nitrogen on growth yield attributes and yield of scented rice. The six (6) treatments of nitrogen of organic sour viz. 100% N through 1/3 vermicompost+1/3 FYM+1/3 poultry manure at basal (T1), 100% N through vermicompost at basal (T2), 100% N through poultry manure at basal (T3), 100% N through 1/2 poultry manure as basal + 1/2 vermicompost at 30 DAT (T4), 100% N through 1/2 vermicompost as basal+ 1/2 vermicompost at 30 DAT (T5) and Control - No application of any nutrients (T6) were tested in randomized block design with four replications. The growth, yield attributing characters and yield of scented rice was significantly highest noted under treatment 100% N through 1/3 Vermicompost+1/3 FYM+1/3 Poultry manure at basal (T1), which was at par to treatment 100% N through 1/2 poultry manure as basal + 1/2 vermicompost at 30 DAT (T4).
