Abstract:
A field experiments was conducted during the rabi seasons of 2015-16 and 2016-17 in a split-plot design having four tillage practices in main plots and five nutrient sources in subplots with three replications to find out their effects on yield attributes and yield of sweet corn (Zea mays L. Ssp. saccharata). Sweet corn crop grown in soil prepared with one mouldboard ploughing + one pass of cultivator + one pass of rotavator (T₄) recorded significantly the highest yield attributes, green cob yield and green fodder yield over rest of the tillage practices. Combined application of 75% recommended dose of nitrogen (RDN) through chemical fertilizers + 25% RDN through vermicompost (S₃) recorded significantly higher value of yield attributes, green cob yield with sheath and green fodder yield over rest of the nutrient sources. Tillage practice T₄ recorded significantly maximum gross returns of Rs. 356968 and net returns Rs. 238648 /ha than other tillage practices. Nutrient source S₃ earned significantly higher gross returns of Rs. 356518 /ha and net returns of Rs. 233690 /ha.
