dc.description.abstractA field experiment entitled “Performance of baby corn as influenced by inter crop and nitrogen management” was conducted on a sandy clay loam soil of the Agricultural College Farm, Bapatla, during kharif, 2013 under irrigated conditions. Five intercrops treatments C1: Sole baby corn, C2: Sole Baby corn in paired rows, C3: Baby corn in paired rows + Soybean, C4: Baby corn in paired rows + Blackgram, C5: Baby corn in paired rows + Greengram allotted for Factor – A, while three levels of nitrogen (N1= 100 % RDN, N2= 75% RDN and N3= 125% RDN ) allotted to Factor-B. The experiment was conducted in a Randomized Block Design with factorial concept and replicated thrice. Among the intercroppings, baby corn in paired row + greengram (C5) recorded significantly more plant height (167.3 cm) and dry matter (11599 kg ha-1) accumulation over the sole baby corn. Application of 125% RDN recorded significantly more plant height (168.4 cm) and dry matter (12222 kg ha-1) accumulation compared to that of 100% RDN and 75% RDN throughout the crop growth period. Among the intercroppings, baby corn in paired row + greengram (C5) recorded significantly more yield attributing characters like ear length (13.93 cm), cob weight (62.5 g), ear weight (20.9 g), over the sole baby corn. Yield attributing characters like ear length (14.50 cm), cob weight (61.6 g), ear weight (21.2 g) were significantly superior with the application of 125% RDN when compared to 100 % RDN and 75% RDN. Among intercrop adjustments, baby corn in paired rows + greengram (C5) recorded significantly higher cob (17048 kg ha-1) and ear yield (5597 kg ha-1) over sole baby corn. Significant increase in baby corn yield and fodder yield was noticed with increasing level of nitrogen. Higher cob (17369 kg ha-1) and ear yield (6064 kg ha-1) were obtained with the application of 125% RDN over 100% and 75% RDN. The highest green fodder yield (58.8 t ha-1) was obtained with baby corn in paired rows + greengram (C5) but, it was on a par with baby corn in paired rows + black gram (C4). Application of 125% RDN recorded the maximum green fodder yield (59.9 t ha-1) which was significantly superior to 100% RDN as well as 75% RDN treatments. Significantly the higher nitrogen uptake (192.5 kg ha-1) was recorded with baby corn paired rows + greengram (C5) system whereas the maximum nitrogen uptake (207.8 kg ha-1) recorded was with the application of 125% RDN at all the stages of crop growth. The highest gross returns (Rs. 224880 ha-1), net returns (Rs. 195651 ha-1) and returns per rupee investment (6.69), were obtained under baby corn in paired rows + greengram (C5) at all the levels of nitrogen.en_US
