Abstract:
A field experiment was conducted at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, Uttar Pradesh, with a view to compare the production potential under different doses and source of nutrients and also to find out the economic viability of this cultivar for soil quality. The treatments comprised of Control (T₁), NPK- (150:60:40 kg ha^-1) (T₂), 100% NPK + Nano Zn Spray (25 DAT) (T₃), 100% NPK + Bio-stimulant Spray (25 DAT) (T₄), 75% NPK + NPK Consortia (T₅), 75% NPK + NPK spray (25 DAT) (T₆), 75% NPK + NPK Consortia + Nano N spray (25 DAT) (T₇), 75% NPK + NPK Consortia + NPK spray (25 DAT) (T₈), 75% NPK + NPK Consortia + NPK spray (25 DAT) + Bio-stimulant Spray (25 DAT) (T₉), 75% NPK + NPK Consortia + NPK spray (25 DAT) + Bio-stimulant Spray (25 DAT) + Nano Zn spray (25 DAT) (T₁₀), 75% NPK + NPK Consortia + Nano Zn spray (25 DAT) (T₁₁) and 75% NPK + NPK Consortia + Nano N spray (25 DAT) + Nano Zn spray (25 DAT) (T₁₂). Results revealed that treatment T₁₀ (75% NPK + NPK Consortia + NPK spray (25 DAT) + Bio-stimulant Spray (25 DAT) + Nano Zn spray (25 DAT) and T₃ (100% NPK + Nano Zn Spray (25 DAT) exhibited significant influence on yield attributes and yields of rice as compared to the application of 100% NPK alone. The maximum gross return was obtained in T₃ followed by T_10. The highest net return was obtained in T₃ followed by T₁₀, while minimum gross return and net return was obtained in T₁ during both the years. Application of 100% NPK + Nano Zn Spray (25 DAT) (T₃) and 75% NPK + NPK Consortia + NPK spray (25 DAT) + Bio-stimulant Spray (25 DAT) + Nano Zn spray (25 DAT) (T₁₀) recorded higher gross return, net return and B:C ratio due to higher cost of zinc and iron. Higher values of B: C ratio (2.48 & 2.64) was obtained in T₃ during 2021 and 2022.
