    STUDIES ON LEVELS OF PHOSPHORUS AND SULPHUR ON YIELD, QUALITY AND UPTAKE OF NUTRIENTS BY CHICKPEA IN A VERTISOL UNDER IRRIGATION
    (University of Agricultural Sciences Dharwad, 2014-12) ASHOK S. SINDAGI; Dr. N. S. HEBSUR
    A field experiment entitled “Studies on levels of phosphorus and sulphur on yield, quality and uptake of nutrients by chickpea in a Vertisol under irrigation” was conducted at Water Management Research Centre (WMRC) Belavatagi of Dharwad district situated in the northern dry zone (Zone-3) of Karnataka during Rabi 2013-14. The experiment was laid out with RBD with chickpea CV. JG-11 and twelve treatment combinations viz., three levels of phosphorus and two levels of sulphur fertilizers with three replications. The results of field experiment revealed that, application of phosphorus @ 75 kg + sulphur @ 30 kg/ha resulted in the highest plant height (49.04 cm), number of branches (8.60), number of pods per plant (69.40) and nodules count (27.33), dry matter production (58.39 q/ha), grain yield (29.72 q/ha) and crude protein content (24.63 %). However, treatments T10 (P2O5 @ 50 kg + S @ 30 kg/ha) and T11 (P2O5 @ 75 kg + S @ 15 kg/ha) were on par with T12. The highest uptake of N, P, K and S (175.09, 27.77, 121.99, 22.95 kg/ha, respectively) registered with the treatment T12 (P2O5 @ 75 kg + S @ 30 kg/ha). However, treatments T10 and T11 were on par with T12 and were significantly superior over rest of the treatments. The higher available N, P and S values (112.75, 26.12 and 37.79 kg/ha, respectively) were recorded in the treatment receiving P2O5 @ 75 kg + S @ 30 kg/ha (T12). However, treatments T10 and T11 (110.51, 112.00 N kg/ha) T9, T10 and T11 (22.95, 23.35, 25.69 P kg/ha) and T10 (36.14 S kg/ha, respectively) were on par with T12. Application of P2O5 @ 75 kg + S @ 30 kg/ha (T12) recorded the highest gross income (Rs. 92027) and net income (Rs. 68910).
