Summary

Rice (Oryza sativa L.) cv. IR8 was grown in sand culture with nutrient solutions of normal (40 ppm) nitrogen (N), and 3 times the normal nitrogen (3N) applied in the form of ammonium nitrate in combination with molybdenum as foliar spray at the rates of 0, 15. 30, and 45μg per plant. In both the nitrogen concentration the foliar application of molybdenum increased the mean crop growth rates. Molybdenum application also increased nitrate reductase activity leading to higher concentration of reduced nitrogen in the tissue and thereby creating a concentration gradient for the uptake and assimilation of applied nitrogen. re]19760505
