| dc.description.abstract | This study investigate the effects of different fertilizer management strategies on carbon stock, selected soil physicochemical properties and on growth performance and economics of lowland hybrid rice. The experiment was laid out in Randomized Complete Block Design consisted of five treatments; T1 - Control, T2 RRIF (15-38-58 N-P2O5-K2O kg/ha), T3 - RRIF (120-60-60 N-P2O5-K2O kg/ha), T4 - RROF (32.65 tons/ha of compost) and T5 - 50% RRIF (75.5-19-20 N-P2O5-K2O kg/ha) + 50% RROF (16.33 tons/ha of compost) with three replications. Soil sample before fertilizer application and after harvesting were analysed to determine selected soil physio-chemical properties. The results indicated that application of organic fertilizer improved the soil carbon stock, organic matter, pH, available phosphorus and exchangeable potassium. On the other hand, using inorganic fertilizers along significantly increase olant height and tiller dynamics of lowland hybrid rice. Grain yield was also increased with the used of inorganic fertilizers but is comparable with the application of compost together with inorganic fertilizer. Among the fertilizer treatments, using inorganic fertilizers alone at different rates gave the highest net income and return over expenses. | |
