Effect of different organic nitrogen sources on growth and yield of wheat (Triticum aestivum L.)

Abstract

The experiment was conducted during rabi season of 2016-17 at Agronomy Organic Farm, College of Agriculture, Pune and laid out in randomized block design with eight treatments and three replications. The treatments consisted of 4 different organic manures i.e. FYM, vermicompost, poultry manure and neem seed cake and their combinitions. Growth characters like plant height (78.51 cm), number of tillers m-1 row length (122.50), dry matter plant-1 (16.31 g) and number of spikes m-2 (410) were significantly highest recorded in 100% RDN through vermicompost. The yield and yield attributing characters like grain yield and straw yield, length of spike, number of spikelets spike-1, number of grain spike­-1, grain weight spike­-1 and test weight were maximum with application of 100% RDN through vermicompost.
