| dc.description.abstract | A field experiment was carried out during the kharif season (June–October) of 2016 at the Research Farm of the Indira Gandhi Agricultural University, Raipur (C.G.), India to study the “Assessment of site specific nutrient management on yield, NPK uptake and nutrient use efficiency of rice in Vertisol”. The experiment was laid out in a Randomized block design with three replications and eight treatments namely i.e. RDF(100:60:40:5 NPK and Zn kg ha-1),SSNM based on nutrient expert (120:60:60:5, NPK&Zn kg ha-1), SSNM based on leaf colour chart (60:60:60:5, NPK& Zn kg ha-1, rest 50% N based on LCC), SSNM-N, SSNM-P, SSNM-K, Control (N0, P0, K0) and Farmer Fertilizer Practices (N80, P40, K0). The results obtained in this study showed that the T2-SSNM based on nutrient expert performed significantly better than the other treatments for yield attributing characters viz. number of tillers 400, number of panicle 350, panicle length 24.30 cm, filled grain per panicle 145, test weight of 1000 seeds of rice 28.8gm, grain yield 50.2q ha-1 and straw yield 82.8q ha-1, nutrients uptake- nitrogen 114.3 kg ha-1 ,Total phosphorus 21.5 kg ha-1 and 185.9 kg ha-1 potassium, nutrient use efficiency of rice (cv. Rajeshwari) recorded for nitrogen 40.4%, phosphorus 21.2% P, potassium 138 % and after harvest of Rice in soil found the available N 196.6 kg ha-1, available P 16.5 kg ha-1, available K 498.3kg ha-1 . The chemical properties of soil viz pH 7.4, Electrical conductivity 0.26 dSm-1, Organic carbon 0.54 g kg-1,available N 196.6 kg ha-1, available P 16.5 kg ha-1, available K 498.3kg ha-1and micronutrient, Zn 0.80mg kg-1was found higher in T2-SSNM on NE and lowest was found under control treatment at harvest of rice.SSNM Treatment based on nutrient expert (NE) recommendations proved superiority over applied different treatments on yield ,nutrients uptake (N,P,K & Zn) involved balance removal as required by rice as well sustaining soil available nutrient status. | en_US |
