USE OF SOME ORGANIC MATERIALS AS A FOLIAR APPLICATIONS IN RICE PRODUCTION AND REDUCTION OF MINERAL N-FERTILIZERS
Soil, Water and Environmental Res. Inst., Agric. Res. Center, Giza, Egypt.
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.
