DEVELOPMENT OF FERTILIZER PACKAGE FOR MUNGBEAN (Vigna radiata L.)

Abstract

An experiment was conducted at the On Farm Research Division, BARI, Chelopara, Bogra during the period from March to May, 2017 to study „Development of fertilizer package for Mungbean (Vigna radiata L.)‟ using Randomized Completely Block Design with three replications. In this experiment 8 treatments were applied. These treatments were-T1= 100% NPK (21-20-29 NPK Kg/ha), T2= T1+25% N (26.25-20-29 NPK Kg/ha), T3= T1+25% NP (26.25-25-29 NPK Kg/ha), T4= T1+25% NK (26.25-20-36.25 NPK Kg/ha),T5= T1+25% PK (21-25-36.5 NPK Kg/ha), T6=T1+25% NPK (26.25-25-36.25 NPK Kg/ha), T7=75% of T1 (17.75-15-21.75NPK Kg/ha), T8 = Control (Native fertility). Result showed that a significant variation was observed among the treatments in respect of the maximum parameters. Nitrogen, Phosphorus and Potassium showed significant effect on all yield contributing characters as well as the seed yield of mungbean. The highest seed yield (1.53 ton/ha) was recorded at the T6 treatment that is T1+ 25% NPK (26.25-25-36.25 NPK Kg/ha). Treatment T6 offered the highest number of branches per plant, number of leaves per plant, number of pods per plant, pod length, 1000-seed weight, straw yield, and biological yield whereas the lowest value of the same parameters was found in T8 (control) treatment. It was revealed that the treatment T6 was better than that of all other treatments.
