Effect of zinc and nano urea on growth and yield of pearl millet (Pennisetum glaucum L.)

Abstract

A field experiment was conducted during Kharif season of 2023 at Crop Research Farm Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture Sciences and Technology. To determine “Effect of zinc and nano urea on Growth and yield of Pearl Millet”. The treatments consisted of three different levels of zinc (15 kg/ha, 20 kg/ha, 25 kg/ha) respectively and three different levels of nano urea (2 ml, 3 ml, 4 ml) respectively. The result revealed that treatment 9 (ZnSO4-25 kg/ha + Nano urea-4 ml/l) recorded significantly higher plant height (162.6 cm), plant dry weight (61.39 g), ear head length (29.63 cm), number of grain/earhead (1616), test weight (9.5 g), grain yield (2.96 t/ha) and straw yield (11.96 t/ha). The aforesaid treatment also recorded cost of cultivation (38977.7 INR/ha) gross return (136812.86 INR/ha), net return (97835.16 INR/ha) and B:C ratio (2:5).
