The treatments consisted of four date of sowing viz., 20 th February (D 1 ), 2 nd March (D 2 ), 12 th March (D 3 ) and 22 nd March (D 4 ) in main plot and four planting geometry practices viz., 40 cm x 20 cm (S 1 ), 40 cm x 25 cm (S 2 ), 45 cm x 20 cm (S 3 ) and 45 cm x 25 cm (S 4 ), in sub- plot with three replications. The results revealed that 2 nd March sowing recorded higher plant height, number of cobs per plant, weight of cob, cob yield and fodder yield which was at par with 12 th March sowing and significantly higher than other sowing dates. Similar effects of these treatments were also observed in respect to N, P, K uptake and economics. Among the different planting geometry, yield of cob without husk and fodder yield, gross return and net return were found to be higher under spacing 45 cm x 20 cm as compared to others. Total N, P and K uptake were also found to be higher under 45 cm x 20 cm spacing than rest of the planting geometry. Planting geometry had non-significant effect on available N,P 2 O 5 and K 2 O status of soil after harvest of the crop. Keywords: Baby corn; planting geometry; dates of sowing; yield; nutrient uptake. 1. INTRODUCTION Baby corn is a high-value crop used as a vegetable that can help poor farmers diversify their agricultural and enhance their income. It is a common ingredient in salads and soups. The waste portion which is not edible such as stem, leaves, fiber etc., can be fed to cattle as green fodder. Baby corn as a cash crop for intensive agro- ecosystems, in which small farmers Original Research Article
