Effect of Organic Source of Nitrogen on Growth, Yield and Economics of Baby Corn

Abstract

The experiment was conducted during rabi season of 2016-17 at Agronomy Organic Farm, College of Agriculture, Pune and experiment layout was randomized block design with twelve treatments and three replications. The treatments consisted of 6 different organic manures, i.e. FYM, vermicompost, poultry manure, seed cake, castor seed cake and cotton seed cake and their combinations. Growth characters like plant height (176.67 cm), leaf area plant-1 (87.33dm2), dry matter plant-1 (452.13 g), days to silk initiation (77.33) were significantly the very best recorded in 100% RDN through poultry manure. The yield and yield attributing characters that are cob yield, green fodder yield, number of baby cobs plant-1, length (with husk and without husk), weight (with husk and without husk) and girth (with husk and without husk) of baby corn were maximum with the applying of 100% RDN through poultry manure. Among various treatments maximum gross (3, 41,667 Rs. ha-1) and net monetary returns (2, 55,397 Rs. ha-1) were obtained by application of 100% RDN through poultry manure. The utmost benefit-cost ratio (3.96) was recorded with the applying of 100% RDN through poultry manure, whereas, minimum B: C ratio (1.50) was registered in absolute control.
