ABSTRACT
This study was carried out to access the response of castor (Ricinus communis L. Var. DS-30) for varying level of Nitrogen, phosphorus and potassium under arid climatic conditions of Bahawalpur on clay loam soil. This experiment was laid out in randomized complete block design. Data on plant height, branches per plant, capsules per plant, number of seeds per capsule and yield was taken into account at maturity and statistically analyzed. All yield contributing traits showed positive response with increase in fertilizer rate. Maximum yield was found at T6 (NPK @ 40:30:15) and T6 and T7 (NPK @ 40:30:30) showed parity for seed yield. Significant difference was not observed in increase in yield due to the addition of potassium but branches per plant showed substantial difference. Highly significant positive correlation was observed for yield and yield contributing traits.
