EFFECT OF PHOSPHORUS, MOLYBDENUM AND Rhizobium INOCULATION ON GROWTH AND NODULATION OF MUNGBEAN (Pages : 25 - 30)

A pot experiment was conducted during Kharif, 2005 at the Soil Science Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. There were four levels of phosphorus (P) (0, 20, 40, 60 kg/ha) and 2 levels of molybdenum (Mo) (1.0 and 1.5 kg/ha) having a common Rhizobium inoculant, one control with no Rhizobium or fertilization and a Rhizobium inoculation only were applied. The performance of Rhizobium inoculant alone was superior to control in almost all parameters of the crop studied. Rhizobium inoculation along with P and Mo significantly increased the growth of plants, number of nodules, dry matter production as well as grain yield of mungbean significantly compared to uninoculated control. Nodulation (nodule number/plant) was the highest with 20 kg P/ha and 1.0 kg Mo/ha. However, P and Mo application at the rate of 40 kg P/ha and 1.0 kg Mo/ha progressively and significantly increased dry matter content of shoot and root of mungbean. Seed yield/plant was positively correlated with the number of nodules/plant. From this point of view, nodule number/plant with 20 kg P/ha and 1.0 kg Mo/ha, and yield and attributes of mungbean combined application of Rhizobium inoculant with 40 kg P/ha and 1.0 kg Mo/ha was considered to be the balanced and suitable combination of fertilizer nutrients for achieving the maximum output through cultivation of mungbean.
