Effect of Row Spacing and Nitrogen Sources on Growth, Yield and Economics of Babycorn (Zea mays L.)

Abstract

The greater challenges of the 21st century is affordably meeting nutritious food demand for a world population which were expected to surpass 9.6 billion people at middle of the century and at the same time sustaining a quality and quantity of a natural resources and biodiversity. Coming to the reality a need of urgent attention for technological innovations in a sector of food production ultimately leading for “greater protein and energy production per unit of resource input”. Therefore, a field experimented was conducted at Chamelti Agriculture Farm, MS Swaminathan School of Agriculture, Shoolini University of Biotechnology and Management Sciences, Solan during kharif season of 2022 to study the effect of row spacing and nitrogen sources on growth, yield and economics of babycorn. The results reveals that significantly higher growth and yield attributing characters were observed with wider spacing of (R3) 60 cm and (N4) nano urea. However, higher yield and economic returns were significantly higher with row spacing of (R2) 45 cm along with (N4) nano urea. On the basis of B: C ratio, row spacing of (R2) 45 cm along with (N4) nano urea was found to be remunerative for baby corn under Mid hills of Himachal Pradesh.
