Effect of Liquid Nanourea Application on Yield, Post-harvest Plant and Soil Nutrient Status in Finger Millet (Eleusine coracana L.) Production

Abstract

A field experiment was conducted at department of Agronomy, PAJANCOA & RI, Karaikal, during Kharif 2021.The experiment carried out in Randomized Block Design (RBD) with eleven treatments replicated thrice. The results proved that combined application of conventional urea and liquid nano urea significantly influenced most of yield parameters of finger millet. Among different treatments, application of 50 % RDN as conventional urea + RD with LNU showed maximum Yield parameters. Experimental results also revealed that 50 % RDN as conventional urea + RD with LNU recorded higher grain yield of 1783 kg ha-1 which was 56.8 and 127.3 per cent increased yield over100% RDN as conventional urea and absolute control. Maximum straw yield (9146 kg ha-1) was observed in100% RDN as conventional urea. The treatment also proved the uptake of nitrogen and potassium increased by 23.8 and39.61per cent, respectively over100 % RDN as conventional urea and 79.8 and 107 per cent, respectively over absolute control. Application of liquid nano urea improved the nitrogen use efficiency by 20 per cent compared to conventional fertilization. An overview of the study revealed that 50%RDN as conventional urea +RD with LNU@1000 ml ha-1saved 50per cent of conventional urea and significantly improved the yield of finger millet.
