| Abstract | ||
| Two field experiments were conducted at Sakha Agriculture Research Station in two successive seasons of 2005 and 2006 to evaluate the effect of some organic compounds as a foliar applications (2000 ppm citric acid and 10% methanol) separately or together with adding three nitrogen rates to the soil (30, 45 and 60 kg N fed-1) on rice production and reduction of mineral N-fertilizers. The obtained data generally showed that the addition of such organic compounds with 60 or 45 kg N fed.-1 produced significantly higher yield and yield components. Also data indicated that using these organic compounds with 45 kg N fed.-1 significant increased N, P and K content in rice plants. The percentage of protein content in rice grains increased by using these organic compounds. Using these organic compounds leads to decreased of mineral N-fertilizer applications about 25% thus reducing pollution of the environment. | ||
