Effect of Nano Urea and Zinc on Growth and Yield of Kharif Maize

A field experiment was conducted with the objective to evaluate the Effect of Nano Urea and zinc on growth and yield of Kharif maize during kharif (Monsoon) season of 2023 at Crop Research Farm Department of Agronomy. The treatments consisted of 3 levels of Nano urea (3,4,5 ml/l) and 3 level Zinc (0.3 %,0.5 %,0.7 %) along with recommended doses of nitrogen and potash and a control (120-60-40kg N-P-K/ha). The experiment was laid out in a Randomized Block Design with 10 treatments and replication thrice. Application of Nano urea at 4ml/l at 0.5% Zinc (Treatment 5) recorded highest plant height (226.71cm), no. of leaves (14.18), dry weight (104.67 g) and crop growth rate (5.926 g/m2/day), yield attributes and yield viz ., No. of cobs/plant (1.33), No. of grains / row (23.56), No. of rows / cob (13.900),seed index (23.10 g), grain yield (6.05 t/ha) and stover yield (8.99 t/ha ) compared to control.
