INTERACTION OF PHOSPHORUS AND MOLYBDENUM IN RELATION TO UPTAKE AND UTILIZATION OF MOLYBDENUM, PHOSPHORUS, ZINC, COPPER AND MANGANESE BY RICE

The effect of P and Mo alone and combined, on the uptake and utilization of Mo, Mn, Zn, Cu and P by rice (cv. IR-579) was studied in the greenhouse at varying levels of Mo (0.25 and 5.0 ppm) and P (0.100 and 200 ppm). Application of P increased the dry matter yield of shoot and root. Combined application of P and Mo increased the dry matter yield of shoot. Application of Mo increased the concentration of Mo and P in shoot. Applied P caused an increase in the concentration of Mo, Zn and P in shoot. Combined application of P and Mo resulted in an increase in concentration and uptake of Mo in shoot.
