Abstract
Aim: To study the retaliation performances of Sulphur and zinc on growth, yield and yield attributes of cowpea (Vigna unguiculate L.)
Place and Duration of Study A field experiment was carried out during kharif season of 2021 at Crop Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj Uttar Pradesh, India.
Methodology: The Experiment was laid out in Randomized Block Design with Ten treatments which were replicated thrice. with treatment combination of (T1 to T10) T1 20 kg/ha S + 10 kg/ha Zn, T2. 20 kg/ha S + 15 kg/ha Zn, T3. 20 kg/ha S + 20 kg/ ha Zn, T4. 30 kg/ha S + 10 kg/ha Zn, T5. 30 kg/ha S + 15 kg/ha Zn, T6. 30 kg/ha S + 20 kg/ha Zn, T7. 45 kg/ha S + 10 kg/ha Zn, T8. 45 kg/ha S + 15 kg/ha Zn, T9. 45 kg/ha S + 20 kg/ha Zn, T10 Control were used.
Result: Among various sulphur and zinc combinations T9 treatment recorded maximum
Plant height (75.64 cm), plant dry weight (67.90g/plant), number of branches per plant (9.66), harvest index (47.93 %), gain yield (13.67 q/ha), straw yield (15.26 q/ha).
Conclusion: It was determined that the application of Sulphur – 45 kg/ha + Zinc – 20 kg/ha resulted in a higher grain yield (13.67 q/ha), which was significantly superior to the other treatments.
