Evaluation of Baby Corn Hybrids Productivity and Profitability under Different Fertilizer Doses and Spacings

A field experiment was conducted during kharif season of 2014 at Agricultural Research Station, Banswara (MPUAT), Rajasthan in split-split plot design having two fertilizer doses (150:50:60 and 200:60:80 kg of N: P₂O₅:K₂O ha⁻¹) in main plots and two plant spacing viz. 60×20 cm² and 60×15 cm² in sub plots, while 4 hybrids (Vivek hybrid-27, HM-4, Seed Tech-2524 and HQPM-4) sown in sub-sub plots with three replications. Results revealed that spacing of 60×15 cm² and 200:60:80 kg NPK ha⁻¹ significantly increased the plant height, green fodder yield, green ear yield with husk and without husk of hybrids over 60×20 cm² and 150:50:60 kg NPK ha⁻¹, respectively. Seed Tech-2324 produced significantly maximum green ear yield (121.52 q ha⁻¹) and dehusked cobs weight (20.13 q ha⁻¹) over HM 4 (65.93 and 12.32 q ha⁻¹), Vivek hybrid-27 (83.65 and 15.80 q ha⁻¹) and HQPM-4 (114.73 and 19.22 q ha⁻¹), respectively. The maximum green fodder yield (244 q ha⁻¹) obtained with Vivek hybrid-27 and was significantly 38.64, 22.00 and 8.44% higher than HM 4 (176 q ha⁻¹), Seed Tech 2324 (200 q ha⁻¹) and HQPM-4 (225 q ha⁻¹), respectively. The maximum green ear yield (22 q ha⁻¹) of Seed Tech-2324 and fodder yield (283q ha⁻¹) of Vivek hybrid-27 while, B: C ratio (3.49) of HQPM-4 was found with the interaction of 60×15 cm² and 200:60:80 kg NPK ha⁻¹.
