The study was conducted at PhilRice-Isabela during the 2009 wet season, it aimed to determine whether there would be a significant effects to yield if PalayCheck recommendations on seed use, plant spacing and nutrient management are altered. Good seeds and certified seeds of PSB Rc82 were used as test variety. Results showed the combination of 25 x 25 cm plant spacing, certified seeds, and farmer's practice (104-14-14 NPK/ha) got the highest grain yield (7.76 t/ha). The same combination except that good seeds were used instead of certified seeds, yielded 6.65 g/ha. However, there was no significant effect of nutrient management in terms of yield and yield components. Use of good seeds instead of certified seeds did not have significant effect on the yield and yield components. On the other hand, altering the plant spacing had significant effect to yield and yield components. Further evaluation and analysis are needed to determine the best combination of nutrient management, seed quality, and plant spacing for optimum yield.
