Effect of different organic sources of nitrogen on concentration and uptake of nutrients in scented rice (Oryza sativa L.)

Abstract

A field experiment was conducted at Research cum Instructional Farm, IGKV, Raipur during kharif 2014 and 2015 to study the effect of different organic sources of nitrogen on concentration and uptake of nutrients in scented rice. The six (6) treatments of nitrogen of organic sources viz. 100% N through 1/3 vermicompost+1/3 FYM+1/3 poultry manure at basal (N1), 100% N through vermicompost at basal (N2), 100% N through poultry manure at basal (N3), 100% N through 1/2 poultry manure as basal + 1/2 vermicompost at 30 DAT (N4), 100% N through 1/2 vermicompost as basal+ 1/2 vermicompost at 30 DAT (N5) and Control - No application of any nutrients (N6) were tested in randomized block design with four replications. The grain, straw and total nitrogen, phosphorus and potassium uptake by scented rice were significantly highest noted under treatment 100% N through 1/3 Vermicompost+1/3 FYM+1/3 poultry manure at basal (N1), which was at par to treatment 100% N through 1/2 poultry manure as basal + 1/2 vermicompost at 30 DAT (N4).
