| dc.description.abstract | Application of the nitrogen fertilizers and its availability is an important factor influencing the normal growth and development of the plant and it also influences on the soil properties. So, a field experiment was conducted during Khariff 2011, to study the impact of nitrogen management practices on soil properties, growth and yield of rice. The soil properties were studied by measuring the soil pH, EC, OC, available N, P, K, S, Zn, exchangeable Ca and Mg along with the enzymes activity. The growth and yield were studied by measuring agronomic and yield parameters of rice. Additionally economics of the different management practices was also studied. These nitrogen management practices includes UAS (B) package, STCR approach of nutrient management and other approach in combination with the green leaf manures and different levels of inorganic fertilizers. It was found that the treatment receiving nutrients based on STCR approach and UAS (B) was efficient in improving the soil physico-chemical properties and enzyme activity and it was on par with treatment received 50% N (inorganic) + 25% N (green Leaf) + 25% N (FYM). The yields were significantly greater in STCR and UAS (B) package compare to treatment with 100% (Inorganic) and other treatments. Lower B: C ratio obtained in only organic manure treatment and higher B: C ratio recorded in UAS (B) treatment. | en_US |
