Impact of N-nano fertilizer on yield attributes, economic and quality of pearl millet (Pennisetum glaucum L) under rainfed condition

Abstract

A field experiment was conducted during Kharif season of 2021 at Agronomy Section, College of Agriculture, Latur (Maharashtra) to study the impact of n-nano fertilizer on yield attributes, economic and quality of pearl millet (Pennisetum glaucum L) under rainfed condition. The experiment was laid out in Randomized Block Design. The results showed that the application of 75% RDN through urea as soil application + 25% RDN through 1 spray of nano- urea @ 45 DAS (T5) recorded significantly highest yield attributes, seed yield (3967 kg ha-1) and test weight (20.77 g) over all the treatments except 75% RDN through urea soil application + 25% RDN through 1 spray of @ 45 DAS (T8) and 50% RDN through as soil application + 50% RDN through 2 sprays of nano-urea @ 30,45 DAS (T4). The highest gross monetary return GMR (85291 ₹ ha-1), net monetary return NMR (53825 ₹ ha-1) and B:C ratio (2.71) was observed with the 75% RDN through urea as soil application + 25% RDN through 1 spray of nano- urea @ 45 DAS. Among the different treatments that application of urea through soil and application of nano urea through spray may increase both quantitative and qualitative yield of pearl millet.
