abstract
A field experiment was conducted on medium black calcareous soil at Junagadh (Gujarat) during rabi season of 2022-23 to study the effect of different levels of nitrogen rates and foliar spray of urea and nano urea on growth, yield and economics of wheat (Triticum aestivum L.). The experiment was laid out in randomized block design with three replications and twelve treatments. The experimental results revealed that significantly higher values of growth parameters viz., plant height, number of total tillers per m row length and dry matter production per plant and yield attributes viz., number of effective tillers per m row length, length of spike, number of spikelets per spike, number of grains per spike, grain weight per spike, 1000-grain weight along with higher grain yield (5841 kg/ha) and straw yield (8273 kg/ha) were recorded with application of 75% RDN + Foliar spray of 0.4% nano urea at 35 and 55 DAS. However, higher net return (₹ 1,22,715/ha) and B:C ratio (4.28) were also realized with the application of 75% RDN + Foliar spray of 0.4% nano urea at 35 and 55 DAS. Based on the results, it could be concluded that higher production and net returns from wheat can be obtained by the application of 75% RDN + Foliar spray of 0.4% nano urea at 35 and 55 DAS.
