Soybean Productivity and Nutritional Quality as Influenced by Graded Phosphorus and Molybdenum Fertilization under Typic Hapludalfs

The present investigation was aimed to evaluate graded P (0, 30, 60 and 90 kg ha^-1) and Mo (0,1 and 2 kg ha^-1) levels through 12 treatment combinations on the yield, nutrient uptake and quality of soybean. The highest grain yield, NPK and Mo uptake was with highest application rates of both the tested nutrients. The protein content and protein yield also recorded remarkable improvements with the same treatments. The conjoint application of 90 and 2 kg ha^-1 P and Mo exhibited a significant impact on number of pods per plant^-1 and Mo uptake by grain. The study concluded that higher soybean yield with enhanced quality under prevailing acidic soil conditions, marked by P fixation and Mo deficiency can be achieved by applying these nutrients at their peak tested rates.
