Abstract:
Background and Objective: Improved soil fertility management is an integral part of crop production. Thus, this study was conducted to investigate the effect of integrated vermicompost and blended NPS fertilizer application on soil physicochemical properties and potato tuber yield. Materials and Methods: The treatment levels consisted of 4 rates of blended NPS fertilizers (0, 150, 200 and 250 kg NPS ha–1) and 4 rates of vermicompost (0, 4, 6 and 8 t ha–1) in factorial combination in randomized complete block design with 3 replications. Results: Soil analysis before planting and after harvesting revealed the incorporation of vermicompost and NPS fertilizer increased OC, CEC, available P and K and total N content of the soil. The organic carbon, available P and available K were increased by 8.7, 14.9 and 13.0% over the initial status, respectively. Furthermore, the integrated use of various rates of vermicompost (VC) and low rates of inorganic fertilizer is better than independent use of inorganic fertilizer. The organic carbon, soil pH, available P and K, CEC and exchangeable bases (Na, K, Ca and Mg) increased due to the application of vermicompost. Combined application of 250 kg ha–1 blended NPS fertilizer and 8 t ha–1 vermicompost gave significantly maximum yield for marketable tuber yield (27.4 t ha–1) and total tuber yield (27.9 t ha–1). Conclusion: The finding suggests combined use of 250 kg ha–1 blended NPS fertilizer with 8 t ha–1 vermicompost increased significantly tuber yield and fertility status of the soil. The regression analysis showed at every increase in levels of both factors, there is a corresponding linear increase in tuber yield.
