Effect of neem coated urea on nutrient availability, yield attributing characters and yield of pearl millet on vertisol

Abstract

A field experiment was carried out during the Kharif season of 2017 at the Pearl Millet Research Scheme, College of Agriculture, Dhule (M.S.) to study the effect of neem coated urea on nutrient availability, yield attributing characters and yield of pearl millet on vertisol. The experiment was laid out in a randomized block design with three replications and eight treatments of neem coated and uncoated urea. The organic carbon content (8.37 g kg-1), available N (188.40 kg ha-1), P (18.10 kg ha-1) and K (490.63 kg ha-1) were observed highest with 100% recommended N through neem coated urea. The maximum available Fe (4.97 mg kg-1), Zn (0.71 mg kg-1) and Cu (0.96 mg kg-1) was noticed under 100% recommended N through neem coated urea, while, the maximum availability of Mn (8.18 mg kg-1) was observed with 100% recommended N through uncoated urea. The significantly maximum plant height (178.33 cm), total number of effective tillers (1.54) and 1000 grain weight (14.10 gm) were recorded in the treatment receiving 75% recommended N through neem coated urea. Significantly higher grain yield (33.11 q ha-1) was recorded in 75% recommended N through neem coated urea followed by 100% recommended N through neem coated urea (32.96 q ha-1).
