A field experiment was conducted at Research Farm of Suresh Gyan Vihar University, Jaipur (Rajasthan) during kharif 2023 on loamy sand soil, which consisted ten treatments viz. control (T₀), Sulphur @ 15 kg ha^-1 (T₁), Sulphur @ 30 kg ha^-1 (T₂), Sulphur @ 15 kg ha^-1 (T₃), Sulphur @ 45 kg ha^-1 (T₄), Sulphur @ 15 kg ha^-1 + Zn @ 0.1% (T₅), Sulphur @ 30 kg ha^-1 + Zn @ 0.1% (T₆), Sulphur @ 45 kg ha^-1 + Zn @ 0.1% (T₇), Sulphur @ 30 kg ha^-1 + Zn @ 0.5% (T₈) and Sulphur @ 45 kg ha^-1 + Zn @ 0.5% (T₉) were laid out in randomized block design with three replication. Variety RC-19 was used for experiment.

Results clearly showed that application of sulphur @ 45 kg ha^-1 + Zn @ 0.5% (T₉)significantly increased plant height, dry matter accumulation, number of branches plant^-1, number of nodules plant^-1, number of pods plant^-1, number of seeds pod^-1, seed, straw and biological yield, of cowpea over control. However, treatment sulphur @ 30 kg ha^-1 + zinc 0.5% (T₈) was remained at par with each other.
