Abstract

The present research trial was led during Zaid season of 2021, at crop research farm of Department of Agronomy, SHUATS, Prayagraj (U.P.) with the goal to evaluate the impact of different levels of nitrogen and sulphur on growth and yield of summer groundnut (Arachis hypogaea L.) under Randomized block design comprising of 9 treatments, with 3 different levels of nitrogen along with 3 different levels of sulphur that are replicated thrice. The results revealed that treatment T9 (50 kg/ha N + 40 kg/ha S) has recorded maximum plant height (56.95 cm), number of nodules/plant (48.20), plant dry weight (42.98 g/plant), crop growth rate (7.11 g/m2/plant), relative growth rate (0.005 g/g/day), number of pods/plant (20.60), kernels/pod (2.00), seed index (41.17g), pod yield (2741.00 kg/ha) and haulm yield (4371.00 kg/ha) at the time of harvest and harvest index (36.74%) was recorded highest with T6 (40 kg/ha N + 40 kg/ha S).

Keywords

Groundnut, Nitrogen, Sulphur, Gypsum, Growth and Yield attributes.

Conclusion

On the basis of the present experiment on groundnut crop in zaid season, it is concluded that treatment T9 with the application of 50 kg/ha nitrogen along with 40 kg/ha sulphur has recorded significantly highest plant height, dry weight, pods/plant, pod yield and haulm yield respectively.
