Effect of different residue management practices and nitrogen levels on growth, yield and economics of soybean [Glycine max (L.) Merrill]

A field experiment was carried out at Ludhiana during kharif season of 2009 to evaluate the effect of residue management practices and nitrogen levels on growth, yield and economics of soybean using rotavator. No residue level showed superiority in terms of growth, development and yield and yield attributing characters. N50+N50 FYM gave comparably better results in relation to growth, development and ultimately higher yield and yield attributing characters. From economic point of view, RF under crop residue management practices and N100 in case of nitrogen levels gave highest profit with B : C ratio of 1.73 and 1.66, respectively.
