Effect of sulfur and zinc nutrition on growth and yield of green gram (Vigna radiata L.)

Abstract

The field experiment was conducted at Research Farm of Agricultural Research Sub Station, Gonera, Kotputli during Kharif seasons of 2020 and 2021. The experiment comprising of 10th treatments combinations of zinc and sulphur nutrition was laid out in randomized block design and replicated thrice. Both the years results showed that the application of T4 - RDF + S@20kg ha-1 + Zn@5 kg ha-1significantly increased yield attributes like number of branches per plant, plant height, number of pods per plant, number of seeds per pod, effective nodules per plant and significantly higher seed (817 kg ha-1 and 933 kg ha-1) and straw (1215 kg ha-1 and 1324 kg ha-1) yield as compared to other treatments. However, treatment T4 (RDF + S@20kg ha-1 + Zn@5 kg ha-1) remained statistical at par with treatment T10 (RDF + mixed fertilizer of S + Zn @ 20 kg ha-1 + Foliar spray of 0.5% Zn) significantly increased seed and straw yield of green gram over rest of the treatments. The maximum net return (Rs. 28688 and 34071 per ha) and B: C ratio (1.50 and 1.56) were recorded under the treatment of T4 (RDF + S@20kg ha-1 + Zn@5 kg ha-1) as compared to other treatments.
