Abstract


Abstract: A field investigation was undertaken to assess “Influence of ghanajeevamrutha and liquid organic manures on soil fertility and productivity of chickpea in vertisol” in medium deep black soils at College of Agriculture, Vijayapura. The experiment was laid out under Randomized Complete Block design (RCBD) with 3 replications, 13 treatments which include different levels of ghanjeevarmrutha application equivalent to recommended dose of phosphorus alone and in combination with cow urine, jeevamrutha and vermiwash. The results showed that application of ghanajeevamrutha @ 100 % of P nutrient requirement (10 t ha-1) + jeevamrutha @ 10 % twice foliar sprays first at flowering stage and second after 15 days, recorded significantly higher organic carbon content (5.27 g kg-1), available N (307.33 kg ha-1), P (29.62 kg ha-1), K (446.33 kg ha-1) and S (22.93 kg ha-1) at harvest stage, higher grain yield (1576 kg ha-1), haulm yield (1852 kg ha-1) and also substantially higher dehydrogenase activity (7.20 and 6.64 µg TPF g-1 soil day-1 , pod filling stage and harvesting stage, respectively) and phosphatase activity (14.56 and 13.78 µg PNP g-1 soil hr-1, at pod filling stage and harvesting stage, respectively), gross returns (`95466 ha-1), net returns (`63291 ha-1) and BC ratio (2.97 ).
