dc.description.abstractThe present study was carried out on turmeric var. Palam Pitamber during kharif 2021 at the experimental farm of Department of Soil Science, CSK HPKV Palampur, to determine the nutrients requirement, contribution of nutrients from the soil, FYM and fertilizers in turmeric in an acid Alfisol. The experiment was conducted on pre-established three fertility gradients which was divided into seventy two plots i.e. each gradient into twenty four plots. There were seventy two treatment combinations comprising of N, P, K and FYM. These treatments were formed by different combinations as per the standard procedure of soil test crop response correlation studies (STCR) and having four levels of N (0, 15, 30 and 45 kg N ha-1 ), P (0, 15, 30 and 45 kg P2O5 ha-1 ) and K (0, 30, 60 and 90 kg K2O ha-1 ) and three levels of FYM (0, 10 and 20 t ha-1 ). The soil was Typic Hapludalf, silty clay loam in texture, acidic in reaction (pH 5.47), medium in organic carbon (7.61 g kg-1 ), low in available nitrogen (256 kg ha-1 ), high in available phosphorus (31 kg ha-1 ) and medium in soil available potassium (190 kg ha-1 ). Soil samples (0-15 cm) collected before the sowing of turmeric crop were analyzed for pH, organic carbon and available N, P and K. The rhizome and haulm samples taken at harvest of turmeric were processed and analyzed to calculate nutrients uptake. The results revealed that the rhizome yield ranged from 94.21 to 224.0 q ha-1 , whereas the yield of haulm varied from 10.09 to 25.01 q ha-1 in different treatments. The total uptake of N, P and K ranged from 21.07 to 52.74, 5.84 to 14.45 and 25.70 to 66.94 kg ha-1 by turmeric, respectively. The amount of nutrients required to produce one quintal of rhizome was 0.25 kg nitrogen (N), 0.06 kg phosphorus (P) and 0.31 kg potassium (K). Per cent contribution of nitrogen (N), phosphorus (P) and potassium (K) from soil was 10.04, 27.26 and 15.57, fertilizer was 46.88, 16.33 and 53.14 and FYM was 3.23, 3.01 and 5.28, respectively. Fertilizer prescription equations were developed with the help of basic parameters viz. nutrient requirement, contribution of nutrients from soil, FYM and fertilizers. The ready reckoners were also generated at a different soil test values for different targets yield of the crop.en_US
