An experiment was conducted with Phalaris aquatica L. cv. Sirolan under hydroponic conditions in the glasshouse at constant temperature of 25 degrees C and natural sunlight. Plants were grown in double pot system with four sulfur and three molybdenum levels along with all the major- and micro-nutrient elements. There was increase in growth, nitrate-reductase activity and contents of most of the nutrient elements at all levels of sulfur and 1.68 micrograms/L molybdenum. Molybdenum at 3.36 micrograms/L level inhibited growth and nitrate-reductase activity and decreased concentration of nutrient elements in plant. The inhibitory effect of higher level of molybdenum is perhaps mediated through its role in the nitrate-reductase.
