Effect of Foliar Application of Nano-urea on Yield Attributes and Yield of Pearl Millet (Pennisetum glaucum L.)

Abstract

To evaluate the effect of different doses of Nano-urea on yield attributes and yield of pearl millet a field experiment was conducted at Eastern Block Farm of Tamil Nadu Agricultural University, Coimbatore during the Summer of 2022. This field experiment was laid out in Randomized Block Design (RBD) with ten treatments and three replications. In this experiment different doses of Nano-urea were applied along with the Recommended Dose of Nitrogen (RDN) as per the Crop Production Guide, 2020 of TNAU, Coimbatore. The study revealed that yield of pearl millet was significantly differed with treatments imposed. Among these treatments, application of 50% RDN as basal + 0.5% Nano-urea foliar spray @ panicle initiation and booting stage recorded a significantly higher number of productive tillers plant-1 (3.79), earhead length (26.82 cm), earhead girth (7.9 cm), number of grains earhead-1 (2,462), test weight (15.64 g), grain yield (3,314 kg ha-1) and stover yield (5,136 kg ha-1). Which was at par with treatment 50% RDN as basal + 25% RDN @ panicle initiation + 25% RDN @ booting stage (T10).

Effect of Soil and Foliar Applications on Growth and Productivity of Pearl Millet (Pennisetum glaucum L.)

“…The lowest grain yield was recorded under 100 percent RDF +Nano-DAP (T1-22.46 q ha -1 ) (Table 1). The increased yield was due to the higher accumulation of photosynthates which were transferred to the economic parts of pearl millet Arya et al [15]. The similar increase in yield was noted in little millet due to the application of Nano-Urea Chavan et al [16].…”

“…The lowest stover yield of 65.11 q ha -1 was recorded under 100 percent RDF +Nano-DAP (T1). The Nano-Urea was easily absorbed and rapidly translocated which caused the higher photosynthetic rate and higher dry matter production which leads to increased stover yield Arya et al [15]. The increased stover yield was due to the efficient nitrogen utilization in finger millet Samanta et al [17].…”

Growth and Yield of Rice (Oryza sativa L.) as Influenced by Irrigation Methods and Nano Fertilizers

“…This led to higher accumulation of biomass thus resulted in higher crop growth rate. Arya (2022) and Chavan (2019) reported higher crop growth rate with foliar spray of nano fertilizers. Crop growth rate was minimum (78.4 and 44.1 kg ha -1 day -1 ) with absolute control plot (S 7 ) at all stages.…”

Effect of Nitrogen Management on Growth and Yield of Pearl Millet (Pennisetum glaucum L.)

“…Nitrogen encourages quick leaf and stem development, which raises production and quality" [2]. "The most common commercial nitrogen fertiliser used to boost agricultural yield is urea" [3].…”
