Effect of Nano Fertilizers on Growth and Yield of Wheat (Triticum aestivum L.)

A field experiment was conducted at Instructional Farm, College of Agriculture, Jodhpur during two consecutive rabi seasons of 2021-22 and 2022-23. The field experiment was tested in randomized complete block design (RCBD) with fourteen treatments replicated thrice. Results showed that the application of 100% recommended dose of fertilizer (RDF) + seed treatment (ST) with nano DAP and two foliar sprays of nano urea at 35 and 55 days after sowing (DAS) was found the most effective treatment with recorded highest number of tillers (431/m2), length of spike (17.03 cm), number of spikes (414 /m2), number of grains (45.24 /spike), test weight (46.32) and grain yield (4399 kg/ha) on pooled basis. However, this treatment was found statistically at par with treatments of 100 per cent RDF + 2 foliar sprays (FS) of nano urea at 35 and 55 DAS, 100% RDF + FS of nano DAP at 35 DAS, 75% RDF + ST with nano DAP and 2 foliar spray of nano urea at 35 & 55 DAS but significantly superior over other treatments.
