Application of Inorganic Fertilizers and The Seedling Number on Growth and Production of Rice (Oryza sativa L.)

The investigation was carried out to determine effect of various doses of inorganic fertilizers and the paddy seedlings number on growth and production (Oryza sativa L.) Three kinds of fertilizer doses are 150-60-67.5 kg/ha, 250-75-75 kg/ha and 350-90-82.5 kg/ha and the number of seeds per planting hole is 20, 25 and 30. This is the experimental research with using split plot design and nine combination treatment. The main plot is the inorganic fertilizers with three level doses, and the sub-plot is some seeds per planting hole. The result shows that the best dose of inorganic fertilizer is 350-90-82.5 kg/ha which rice growth result are plant height 108,95 cm, 35,30 productive panicles and length of panicles is 27.03 cm. Rice production is 7.69 ton/ha. The best number of the seedling is 25 seeds per planting hole with growth result are plant height 109.52 cm, 35,48 productive panicles and length of panicles is 26.65 cm. Rice production is 7.72 ton/ha.
