Abstract

After green revolution, it becomes a practice in agriculture to get maximum production by using more chemical fertilizers and synthetic agrochemicals irrespective of its impact on soil health and environment. Keeping these facts into consideration, a field experiment was conducted during the kharif season of the year 2021 at Agronomy Instructional Farm, CPCA, SDAU, Sardarkrushinagar. The experiment was laid out in randomized block design with three replications. Thirteen treatments comprises different organic sources viz., T1: 100% RDF through chemical fertilizers (control), T2: 100% RDN through castor cake (CC), T3: 100% RDN through poultry manure (PM), T4: 100% RDN through neem cake (NC), T5: 75% RDN through CC + biofertilizers (NPK), T6: 75% RDN through PM + biofertilizers (NPK), T7: 75% RDN through NC + biofertilizers (NPK), T8: 75% RDN through CC + 5% cow urine, T9: 75% RDN through PM + 5% cow urine, T10: 75% RDN through NC + 5% cow urine, T11: 75% RDN through CC + biofertilizers (NPK) + 5% cow urine, T12: 75% RDN through PM + biofertilizers (NPK) + 5% cow urine and T13: 75% RDN through NC + biofertilizers (NPK) + 5% cow urine. The results revealed that an application of treatment T12 was recorded significantly higher N and P content in seed and stover. Accordingly, an application of same treatment (T12) was recorded significantly higher N, P and K uptake by seed and stover. Therefore, treatment T12 was also recorded maximum available N and P2O5 and organic carbon content in soil at after harvest. Thus, it concludes that the application of 25% reduced level of RDN through poultry manure along with biofertilizers and cow urine spray improves the concentration of nutrients (NPK) in produce of clusterbean and also enhance their post-harvest availability in soil thereby sustained soil fertility (T12).

Conclusion

It can be concluded that the application of 75% RDN through PM + biofertilizers (NPK)+ 5% cow urine spray increase the NPK content and uptake by seed and stover of clusterbean and also enhance their availability in soil as well as sustain soil fertility.
