Effect of nano urea on growth, yield attributes and yield of summer pearl millet [Pennisetum glaucum (L.) R. Br.] under real time nitrogen management

A field experiment was carried out under medium black calcareous soil during summer seasons of 2022 and 2023 at the Pearl Millet Research Station, Junagadh Agricultural University, Jamnagar, Gujarat, India, with effect of nano urea on growth, yield and economics of summer pearl millet under real time nitrogen management The results of experiment indicated that overall growth of the crop viz., plant height, number of total tillers per plant, dry matter per plant at 60 DAS and at harvest, physiological parameters viz., CGR at different stages, SPAD value at 45 DAS and leaf chlorophyll content, yield attributes and yield viz., number of effective tillers per plant, earhead length, earhead girth, grain yield, fodder yield and earhead weight of pearl millet were significantly higher with the application of 40 kg N/ha as basal + 40 kg N/ha through urea at 25-30 DAS + two foliar sprays of nano urea 0.4% when LCC ≤ 4 in comparison to other treatments.
