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 zinc enriched and organic sources and also to find out the economic viability of this cultivar for soil quality. The treatments comprised of Control (T₁), 100% NPK (T₂), 100% NPK + Zn @ 5.0 Kg ha^-1 (T₃), 100% NPK + FYM @ 5.0 t ha^-1 (T₄), 100% NPK + FYM @ 5.0 t ha^-1 enriched with Zn @ 0.1% (T₅), 100% NPK + V.C @ 1.5 t ha^-1 (T₆), 100% NPK + V.C. @ 1.5 t ha^-1 enriched with Zn @ 0.33% (T₇) and 100% NPK + Zn @ 2.5 Kg ha^-1 application twice at basal and max. tillering stage (T₈). Results revealed that treatment T₇ (100% NPK + V.C. @ 1.5 t ha^-1 enriched with Zn @ 0.33%) and T₈ (100% NPK + Zn @ 2.5 Kg ha^-1 application twice at basal and max. tillering stage) exhibited significant influence on yield attributes and yields of wheat as compared to the application of 100% NPK alone. The maximum gross return was obtained in T₈ followed by T_7. The highest net return was obtained in T₈ followed by T₇ and T₅, while minimum gross return and net return was obtained in T₁ during both the years. Application of 100% NPK + Zn @ 2.5 Kg ha^-1 application twice at basal and max. tillering stage (T₈) and 100% NPK + V.C. @ 1.5 t ha^-1 enriched with Zn @ 0.33% (T₇) recorded higher gross return, net return and B:C ratio due to higher cost of zinc and vermicompost. Higher values of B: C ratio (2.77 & 2.85) was obtained in T₈ during 2019-20 and 2020-21.
