Turmeric Yield, Soil Properties, Nutrient Uptake and Nutrient Use Efficiency as Affected Under Irrigation Scheduling and Nutrient Sources at Aeric Haplaquept

Alteration of management practices of irrigation and nutrients are the important to enhance the production of crop through better utilization of applied input. On this view, the aim of experiment was identified the best irrigation regimeIrrigation regimes and nutrient supplementNutrient supplements sources for improve rhizome yield, soil fertility and nutrients use efficiency. This study was consisted four levels of moisture regimes and three combinations of nutrient sources. Results showed that the rhizome yield of turmeric was significantly recorded higher than 0.9 irrigation water (IW): cumulative pan evaporation (CPE) ratio. Whereas, integrated nutrient sources i.e., 50% 50% recommended dose of fertilizerFertilizer (RDF) + 50% through organic sources [25% farm yard manure (FYM) + 25% vermicompost] was significantly improved rhizome yield. At the end of experiment, primary nutrient content, electrical conductivity (EC) and organic carbon (OC) in post harvest soil were significantly enhanced through application of irrigation at 0.9 IW/CPE and 50% RDF + 50% organic source. The nutrient content and its uptake in rhizome were observed higher under irrigation at 0.9 IW: CPE, integrated nutrient sources (50% chemical fertilizerFertilizer + 50% organic sources) and interaction of both as compared to other irrigation regimesIrrigation regimes and nutrient sources, respectively. Interaction of 0.9 IW: CPE and integrated nutrient sources (50% inorganic fertilizerInorganic fertilizers + 50% organic manure) were significantly improved partial factor productivity (PFP) of applied nutrients over other irrigation methods and nutrient sources. This study concluded that the application of irrigation on the crop’s water requirement and adoption of integrated nutrient management (INM) may have benefits in terms of rhizome yield and plantTurmeric yield nutrition due to better fertility status of soil.
