Response of nitrogen, Sulphur and foliar application of zinc on yield and quality of greengram (Vigna radiata L.)

Abstract

The field experiment was conducted during kharif season of 2015 at Crop Research Farm SHUATS, Allahabad & the experiment consisted of two levels of nitrogen viz., 15, 25 kg ha–1, three levels of Sulphur viz., 0, 20, 40 kg ha–1 and two levels of 0.1% zinc spray at pre-flowering and pod initiation stage which laid out in Randomized Block Design (RBD) & replicated thrice. Application of 25 kg N ha–1 + 40 kg S ha–1 + 0.1% zinc (Pre flowering and Pod initiation) significantly increased yield & quality parameters viz, Maximum number of pods plant–1 (30.33), Test weight (41.68 g), Seed yield (8.89 q ha-1), Stover yield (27.10 q ha–1). Similarly application of 25 kg N ha–1 + 40 kg S ha–1 0.1% zinc (Pre flowering and Pod initiation) recorded maximum harvest index (24.73 %), Protein content (24.83 %), Gross return (₹ 44092.0 ha–1), Net return (₹ 24739.0 ha–1) and B:C ratio (2.30) while lowest gross return (₹ 29083.0 ha–1), net return (Rs 11109.0 ha–1) and B:C ratio (1.61) was obtained in treatment T1 (control) respectively.
