Abstract:

Studies on Soil Test Crop Response (STCR) based on Integrated Plant Nutrition System (IPNS) were conducted under fertigation using soluble fertilizers on Alfisols of GKVK, Bengaluru, during kharif2017 to develop fertilizer prescription equations through IPNS using soluble fertilizers under fertigation for the desired yield targets of cabbage (Var. Unnati). Four important basic parameters viz., nutrient requirement (NR), contribution of nutrients from the soil (%CS), fertilizer (%CF) and organic matter (%C-OM) were computed using field experimental data. Making use of these basic parameters, fertilizer prescription equations were developed for NPK alone (Inorganics) and IPNS for the desired yield targets of cabbage for a range of soil test values. The percent reduction in NPK fertilizers under IPNS also increased with increasing soil fertility levels with reference to NPK. This could be achieved by integrated use of sheep manure with NPK through soluble fertilizers. In comparison to soil testing laboratory (STL) method, STCR dose of fertilizer application through fertigation using soluble fertilizers was found to be superior for precise and efficient use of fertilizer nutrients in soil fertility maintenance by sustaining high productivity.
