| dc.description.abstract | A study was conducted to evaluate the fertility status of the soil through Minus One Element Technique (MOET) and Laboratory Method in rice production area in Agusan on Farm 1, Agusan on Farm 2, Agusan on Station, Batang Ligao, ICM Bicol and Tuliw. The study was conducted at Agronomy, Soils and Plant Physiological Division (ASPPD), central Experiment Station, Philippine Rice Research Institute (PhilRice) Maligaya, Science City of Munoz, Nueva Ecija. Results through MOET showed that the rice production area in Agusan on Farm 1, Agusan on Farm 2, Agusan on Station, Batang Ligao, ICM and Tuliw were deficient in nitrogen. Results of the laboratory analysis showed that nitrogen in all areas were medium except for the soil in Batang Ligao which is low (0.113%). However, for the phosphorus all of the area were found to be deficient through MOET except for Batang Ligao, ICM Bicol and Tuliw, which was analyzed in the laboratory to obtain high with 50.34 ppm. On the other hand for the potassium, all of the area were found to be deficient through MOET except for the ICM Bicol, which was analyzed to be medium level with 0.33 cmol/kg. Soil samples from different areas used in the study were analyzed for the pH, total nitrogen, available phosphorus and exchangeable potassium using the laboratory method of analysis. Specific fertilizer rates for the different areas were computed through MOET data based on the nutrient deficiencies. Mathematical model was used to optimize fertilizer recommendation to target 6 t/ha harvest of Philippine rice cultivars. Growth preference of rice through Leaf area Index, Crop Growth Rate and Net Assimilation rate were also used as growth parameters in rice. | |
