Abstract
A field experiment was conducted on groundnut during Zaid (summer) season of 2023 at Crop Research Farm Department of Agronomy. The experiment was laid out in a Randomized Block Design with 10 treatments and replicated thrice. The treatment consisted of 3 levels of sulphur (30,40 and 50 kg/ha) and 3 levels of seaweed (Kappaphycus alvarezii) extract spray (5,10 and 15%) along with recommended doses of nitrogen, phosphorus and potash and a control (20-40-20 N-P-K/ha). Application of Sulphur 50 kg/ha along seaweed (Kappaphycus alvarezii) extract spray 10% (treatment 8) recorded maximum plant dry weight (36.17 gm), pod per plant (27.93), seed index (39.90 gm), kernel yield (2.36 t/ha) and B:C (1.90).
