Response of Zinc and Panchagavya on Growth and Yield of Sweet Corn (Zea mays L. saccharata)

A field experiment was conducted during Zaid summer season of 2023 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj. The experiment was laid out in Randomized Block Design (RBD) with 10 treatment and replicated thrice. The results showed significantly increase in growth parameter with application of zinc (25 kg/ha) and panchagavya (3 sprays of 3%) recorded the highest plant height (166.55 cm), dry weight (69.59 g/plant) at 80 DAS. Whereas number of cobs per plant (2.00 g), number of rows per cobs (15.50 g), number of grains per cobs (28.93 g), cob yield (5.24 t/ha) were recorded at harvest. Treatment combination with zinc 25 kg/ha and panchagavya 3 sprays of 3% produced highest gross returns (Rs 2,19,560/ha), net return (Rs 1,61,952.45/ha), and benefit cost ratio (2.81) which was significantly superior to other treatments.
