Abstract:
A field experiment was conducted at Farm of Agronomy section, College of Agriculture, Latur (Maharashtra) during kharif season of 2021 to study the “Effect of foliar application of nano N fertilizer on growth and yield of sorghum (Sorghum bicolor L)”. The experiment was laid out in Randomized Block Design with nine treatments and was replicated thrice viz., T1 - Control, T2 - 75% RDN with commercial urea in 2 equal splits - At sowing & 30 DAS, T3 - Foliar spray of 75% RDN with nano urea in 2 equal splits - 20 & 40 DAS, T4 - Foliar spray of 75% RDN with nano urea in 3 equal splits - 15, 30 & 45 DAS, T5 - 100% RDN with commercial urea in 2 equal splits - At sowing & 30 DAS, T6 - Foliar spray of 100% RDN with nano urea in 2 equal splits - 20 & 40 DAS, T7 - Foliar spray of 100% RDN with nano urea in 3 equal splits - 15, 30 & 45 DAS, T8 - Foliar spray of 125% RDN with nano urea in 2 equal splits - 20 & 40 DAS, T9 - Foliar spray of 125% RDN with nano urea in 3 equal splits - 15, 30 & 45 DAS. The results of the study revealed that higher growth attributes, yield attributes, grain yield (2730 kg ha-1) and stalk yield (6152 kg ha-1) was found in the treatment of 100% RDN with commercial urea in 2 equal splits - At sowing & 30 DAS (T5). It was followed by foliar spray of 125% RDN with nano urea in 3 equal splits - 15, 30 & 45 DAS (T9), foliar spray of 125% RDN with nano urea in 2 equal splits - 20 & 40 DAS (T8) and foliar spray of 100% RDN with nano urea in 3 equal splits - 15, 30 & 45 DAS (T7) and also found significantly superior over rest of the treatments.
