Effect of Sulphur and Zinc on Growth and Yield of Baby Corn (Zea mays L.)

Abstract

A field study was conducted at Crop Research Farm Department of Agronomy SHUATS Prayagraj, (U.P). During zaid season 2023 with the objective of influence of sulphur and zinc on growth and yield of baby corn .Data on growth and yield components of the crop were recorded.The experiment was laid out in Randomized Block Design with 10 treatments and replicated thrice The Treatments consisted of 3 levels of Sulphur (15, 30, 45 kg/ha) and zinc (10, 20, 30 kg/ha) With Baby corn var SYNGENTA (G-5414). The results reported that the application of Sulphur 45 kg/ha along zinc 30 kg/ha recorded maximum plant height (108.7cm), Maximum plant dry weight (49.08 g/plant), Number of cobs per plant (2.07), cob yield with husk (10.06 t/ha), cob yield without husk (3.91 t/ha), green fodder yield (28.43 t/ha). Maximum gross return (92,087.17 INR/ha), net return (61,352 INR/ha) and B:C ratio (2.00) were recorded in (treatment-9) that is with 45 kg of Sulphur+30 kg Zinc. With application sulphur and zinc morphological characters increased which might be attributed to a stronger role of zinc in cell division, cell expansion, and enlargement which ultimately lead to the improved vegetative growth. The interaction effect between sulphur and Zinc was found significant in respect of green and dry matter yield.
