GROWTH AND YIELD RESPONSE OF MUNGBEAN VARIETIES TO VARIOUS POTASSIUM LEVELS
Keywords:growth, K fertilizer, mungbean, yield
Growth and yield response of two mungbean (Mung-06 and NM-92) varieties to different application rates of potassium was evaluated under field condition. Plants were fertilized with five K (00, 50, 75, 100 and 125 kg ha-1) levels. The data obtained from the study indicated that there was significant effect of potassium levels on growth, yield and yield components of both varieties. Compared to Mung-06, the variety NM-92 performed well by displaying maximum seed germination, taller plants with more branches, pods, seeds and biological yield. In addition to the recommended rates of nitrogen and phosphorus, the K applied @ 125 kg ha-1 significantly increased seed germination, plant height, number of branches per plant, number of pods, seed index and biological yield (kg ha-1) as well. The difference between 125 and 100 kg K ha-1 rates for mjority of the growth and yield parameters under study remained non-significant. However, the plants given 75, 50 and 00 kg K ha-1 ranked 3rd, 4th and 5th, respectively for all the recorded yield parameters. It is, therefore, concluded that 100 kg K ha-1 can be the effective rate for achieving economically higher mungbean yield.
