Abstract: A field experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad, (Uttar Pradesh) during kharif season of 2015 and 2016 to study “Effect of nitrogen levels, row ratio and row direction on growth, yield and economics of baby corn (Zea mays L.) Intercropped with pigeon pea (Cajanus cajan L.). The experiment was laid out in Randomised Block Design with 18 treatments and three controls viz. sole pigeon pea, pigeon pea in paired row and sole baby corn each replicated thrice. The pooled results of two year experiment at 60 DAS revealed that treatment T₇ (75% RDN to pigeon pea +100% RDN to baby corn in 1:1 row ratio +East-West row direction) gave maximum values for plant height (157.0cm), dry weight (71.38 g/plant), stem diameter (2.41cm), number of cobs /plant (2.67), length of cobs with husk (16.63cm), length of cobs without husk (8.65cm), weight of cob with husk (25.87 g) and weight of cobs without husk (8.87 g) followed by treatment T₅ (100% RDN to both crops in 1;1 row ratio +East-West row direction) which was found to be at par to treatment T₇ in all attributes mentioned above. However, baby corn yield and green fodder yield was recorded maximum in treatment T₁₆ (Pigeon pea +baby corn in 2:2 row ratio +75% RDN to pigeon pea +100% RDN to baby corn +East-West row direction) as 1.27 t/ha and 22.18 t /ha respectively and followed by treatment T₁₄ (pigeon pea +baby corn in 2:2 row ratio +100% RDN to both the crops +East-West row direction) which was found to be at par to treatment T₁₆. With respect to economics of baby corn production, maximum gross return, net return and BC ratio were computed in treatment T₁₆ which registered values as ₹135960.00, ₹108150.00 and 3.88 respectively.
