Development of Fertilizer Prescription Targeted Yield-Equation for Carrot Crop Based on Soil Test Values

A field experiment was conducted on red soils (Kandic paleustalfs) of Zonal Agricultural Research Station, GKVK, Bangalore during kharif 2008-09 to develop a targeted yield equation for carrot crop. After developing three levels of fertility gradient with respect to available NPK in soil, the main e...

After developing three levels of fertility gradient with respect to available NPK in soil, the main experiment was conducted by taking carrot as a test crop. Initial soil data, carrot root yield and NPK uptake by carrot crop were used for obtaining four important basic parameters, viz., nutrients required to produce a quintal of carrot roots (NR%), contribution of nutrients from fertilizers (CF%), contribution of nutrients from soil (CS%) and contribution of nutrients from organic matter (%C-OM).
