Abstract
An experiment was conducted during kharif 2022 and 2023 at the Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, Uttar Pradesh, to study the Effect of Foliar Application of Nano on Soil properties of Rice (Oryza sativa L.) Under Western UP. The investigation was carried out with fourteen treatments viz. Control, RDF (N:P:K-120:60:40 kg ha-1 + 25 kg zinc sulphate), 100% RDF + Nano urea, 100% RDF + Nano potash, 100% RDF + Nano Zn, 100% RDF + Nano urea + Nano potash + Nano Zn, 75% RDF + Nano urea, 75% RDF + Nano potash, 75% RDF + Nano Zn, 75% RDF + Nano urea + Nano potash + Nano Zn, 50% RDF + Nano urea, 50% RDF + Nano potash, 50% RDF + Nano Zn and 50% RDF + Nano urea + Nano potash + Nano Zn. The nano fertilizers were applied at tillering stage (35 DAT). Result revealed that highest soil properties viz., organic matter % (0.48 & 0.52), available nitrogen (225.6 & 228.7 kg ha-1), available phosphorus (19.5 & 20.7 kg ha-1), available potassium (235.6 & 233.8 kg ha-1) and available zinc (0.80 & 0.83 g ha-1) were recorded with application of 100% RDF + Nano urea + Nano potash + Nano Zn spray at tillering stage (35 DAT) respectively, during both the years. The lowest values of these parameters were recorded under control treatment.
