abstract
A field experiment was conducted at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, Uttar Pradesh in Kharif 2022 & 2023 with a view to compare the profitability through the application of nutrients through different sources, doses and mode of application in Rice. The experiment comprised of 12 treatments and 3 replications analysed in Randomised Block Design. Treatments comprised of T₁ (Control), T₂ (100% NPK), T₃ (100% NPK + Zn 5 kg ha^-1), T₄ (100% NPK + Bio stimulants), T₅ (75% NPK + Bio stimulants), T₆ (100% NPK + Nano Zn spray at 40 DAT), T7 (100% NPK Consortia), T₈ (75% NPK + NPK Consortia), T₉ (75% NPK+ Nano N spray at 40 DAT), T₁₀ (75% NPK+ Nano N spray at 40 DAT+ Nano Zn spray at 40 DAT), T₁₁ (75% NPK+ NPK (18:18:18) 0.5% spray at 40 DAT +Bio-stimulants) and T₁₂ (75% NPK+ Zn 5 kg ha^-1 + Bio-stimulants + Nano N + Nano Zn spray at 40 DAT). Paddy variety Pusa Basmati 1637 was grown during both the years (2022 and 2023) of experimental study. Application of nutrients through different sources, doses and mode of appliication had significant influence on yield of rice during both the years of experimental study. Results revealed that signiicantly highest value of Gross returns (ha^-1) were obtained in T₁₂. In case of Net returns maximum value was obtained in T₁₂ and was found to be statistically at par with T₁₁ and T₇. The highest B.C. Ratio was recorded in T₁₂ which was at par with T₇.
