Influence of organic and inorganic nutrient management on growth and yield of baby corn (Zea mays L.) under high density planting system

Abstract

The field experiment was conducted at Central Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, (U.P.) during Zaid-2020. The soil of experimental site was sandy loam in texture, nearly neutral in soil reaction (pH 7.3), EC (dS m-1), available N (kg ha-1), available P (kg ha-1) and available K (kg ha-1). The experiment was laid out in Randomized Block Design and having ten treatment consisted of Different sources of Nitrogen levels 100% Nitrogen through urea (N1), 75% Nitrogen through Urea + 25% Nitrogen through FYM (N2), 50% Nitrogen through Urea +50% Nitrogen through FYM (N3) and different row spacing 25 cm x 15 cm (S1), 35 cm x 15 cm (S2) and 45 cm x 15 cm (S3) which are replicated thrice and effect was observed on G-5414 variety of Baby corn. The result shown application of 50% Nitrogen through Urea + 50% Nitrogen through FYM +45 x 15 cm significantly maximum plant height (186.5 cm), application of 50% Nitrogen through Urea + 50% Nitrogen through FYM +35 x 15 cm, Dry Weight (106.08 g), CGR (0.0107 g m-2/day) in application of 50% Nitrogen through Urea + 50% Nitrogen through FYM +25 x 15 cm, RGR (0.135 g g-1day-1) was found maximum value of application of 50% Nitrogen through Urea + 50% Nitrogen through FYM +25 x 15 cm and Number of cobs/plant (1.67), Cobs Length of with husk (44.41 cm) and without husk (22.31 cm), Weight of cobs yield (t/ha) with husk (239.1 kg/ha) and without husk (46.9 kg/ha), Stover yield (22.53 t/ha), 50% Nitrogen through Urea + 50% Nitrogen through FYM +35 x 15 cm. Gross return (INR 4,03,710), Net return (INR 2,86,306), and B:C ratio (3.4) was recorded in N3S3 - 50% Nitrogen through Urea + 50% Nitrogen through FYM + 35 x 15cm.
