Influence of Foliar Application of Nitrogen through Urea and Nano Urea on Morphophysiological and Yield in Foxtail Millet (Setaria italica L.)

A field experiment was conducted at College of Agriculture Nagpur, during Kharif 2023 in randomized blocked design (RBD) with PDKV Yashshree (BFTM-82) variety, at Research Farm of Agricultural Botany Section, College of Agriculture Nagpur, with three replications and eight treatments. The results revealed that the best treatment 25 N kg ha-1 + two spray of nano urea @ 4 ml L-1 (T8) applied at tillering and pre-flowering stage was significantly superior as compared to other treatments which shows the highest value in morpho-physiological viz., Plant height (163.00 cm) at 80 DAS, days to 50% flowering (57.00), days to maturity (87.00), RGR (0.095 g-1 dm-2 day-1 ) at 60-80 DAS and CGR (0.82 g-1 cm-2 day-1) at 60-80 DAS and yield parameters viz., No. of panicle hill-1 (4.90), Panicle length (24.37 cm), No. of spikelet panicle-1 (66.07), Grain yield kg plot-1 (1.30),Grain yield kg ha-1 (1421.78),Harvest index (63.50%) of foxtail millet.
