The soil in the experimental plot was sandy loam texture, almost neutral in soil reaction (pH 7.1), low in organic carbon (0.36%), available N (171.48 kg/ha), available P (15.2 kg/ ha) and available K (232.5 kg/ha). The experiment was arranged in a Randomized Block Design with nine treatments each replicated three times based on a one-year experiment with different levels of Phosphorous and Potassium. The results showed that application of 70 kg/ha Phosphorous + 25 kg/ha Potassium was recorded significantly Plant height (162.73 cm), No. of leaves/plant (13.26), Plant dry weight (108.06 g/plant), Cobs/Plant (1.34), Length of Cob/plant (19.29 cm), Girth of Cob/plant (7.64 cm), Cob weight with husk (65.09 g), cob weight without husk (23.63 g), cob yield with husk (15.14 t/ha), Cob yield without husk (5.16 t/ha) as compared to other treatments. Keywords: Baby corn; growth; phosphorous; potassium; yield. 1. INTRODUCTION “Baby corn is a young ear of corn peeled to finger length from the female inflorescence, harvested within 2-3 days after silk emergence but before fertilization, and is crunchy and sweet. We can say that a stalk with unpollinated silk is baby corn. Baby corn cobs of light yellow color Original Research Article
