Nutrient Uptake and Physico : Chemical Properties of Soil Influenced by Organic and Inorganic Packages in Rice

Abstract

Field Study on Nutrient uptake and Physico – chemical properties of soil influenced by organic and inorganic packages in rice was carried out at Research Cum Instructional Farm IGKV., Raipur (C.G.) during kharif 2010 and 2011. The soil of experimental field was ‘Inceptisols’ (Matasi), which was low in nitrogen, medium in available phosphorus and potassium. The experiment was laid out in randomized block design with three replication. The treatments consisted of Basmati type rice variety viz. Kasturi Comprising organic, inorganic and integrated nutrient management. Treatment T1 (50% RDF + 50% N (CDM), T2 (100% N((1/3 rd each CDM +NC+CCR) T3 (100% N (1/3 rd each CDM + NC + CCR) + Green manure in rice), T4 100% N (1/3 rd each CDM + NC + CCR) +Deep summer ploughing), T5 (50% N(CDM)+RP+PSB+Azos.), T6 (100%N(1/3 rd each CDM+NC+CCR) + Azos.+ PSB) and T7 (100% RDF).among different nutrient management practiceshigher nutrient uptake in grain and straw were observed under treatment T7(100% RDF).followed by T1 (50% RDF + 50% N (CDM) an INM treatment.whereas water uptake was exceeding in100% N applied through 1/3 rd each CDM + NC + CCR + Green manure in rice. Bulk density, pH and EC were also exceeds in T7, except T6 (100% N CDM + NC + CCR + Azos + PSB) which has higher OC.
