EFFECT OF SALINITY ON GROWTH AND YIELD OF SUMMER MUNGBEAN

Abstract

The experiment effect of salinity on growth and yield of summer mungbean was conducted at the Agronomy Research Farm of Sher-e-Bangla Agricultural University (SAU), Dhaka during the period from August to November 2013. The experiment consisted of two factors: Factor A: mungbean crop 3 varieties like V1: BARI Mung-6, V2: BINA Mung-5, V3: Local variety (Sonamung) and Factor B: salinity 5 levels eg. T0: 0 dS m-1 (control), T1: 2 dS m-1, T2: 4 dS m-1, T3: 6 dS m-1 and T4: 8 dS m-1. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. In case of variety, the tallest plant (45.33 cm), the highest number of pods plant-1 (16.09), the highest number of seeds pod-1 (8.03) and the highest seed yield plant-1 (6.65 g) was recorded from V1, while those of the lowest (41.40 cm 14.18 cm, 6.69 and 4.34 g, respectively) were found from V3. For levels of salinity, the tallest plant (47.45 cm), the highest number of pods plant-1 (17.56), the highest number of seeds pod-1 (8.38) and the highest seed yield plant-1 (7.56 g) were found from T0, while the parameter4s were recorded as lowest values (36.72 cm, 10.78, 5.70 and 2.62 g, respectively) in T4 treatment. Due to the interaction effect of mungbean varieties and levels of salinity, the tallest plant (51.38 cm), the highest number of pods plant-1 (19.56), the highest number of seeds pod-1 (9.56) and the highest seed yield plant-1 (9.76 g) were found from V1T0, while the parameter4s were recorded as lowest values (34.92 cm, 11.22, 5.43 and 2.62 g, respectively) in V3T4 treatment combination.
