| dc.description.abstract | A study was conducted to evaluate the soil fertility of the rice production areas under Crop Module 1, UBAP, CLSU using minus one-element technique. The study was conducted at the College of Agriculture, Central Luzon State University. Soil samples from different areas used in this study were collected, air-dried and pulverized. The soil samples were analysed for the pH, nitrogen, phosphorus and potassium using STK. Results of the STK analysis showed that nitrogen were low in all areas while phosphorus is at medium level at LMU 7 (Sawmill A). On the other hand, potassium was found to be deficient at LMU 5 (PAGASA) and LMU 6 (Riles). All areas under Crop Module 1 were found to be acidic. For the mOET experiment, two seedlings of twenty day old NSIC Rc 222 were transplanted per container. The plants were grown for 45 days after transplanting. Starting on the 10th days after transplanting, the growth of the rice plants was observed and at 45 days, the growth of the plants in each pot was compared with that in the complete treatment. Results showed that the rice production areas of LMU 1 (PNR) and LMU 7 (Sawmill A) were deficient in nitrogen, phosphorus, potassium and sulfur. On teh other hand, rice production areas in LMU 2 (marketing), LMU 6 (riles), LMU 5 (PAGASA) and LMU 3 (waiting shed) were deficient in nitrogen, phosphorus and potassium. Results also revealed deficiencies in copper and zinc in LMU 4 (nursery) and LMU 8 (sawmill B). Specific fertilizer recommendations for the different LMU areas based on the nutrient deficiencies were also formulated. | |
