EFFECT OF SALICYLIC ACID AND CaSO4 ON MORPHOLOGICAL CHARACTERS AND YIELD OF MUNGBEAN

Abstract

The experiment was conducted at the research plot of the department of Agricultural Botany of Sher-e-Bangla Agricultural University, Dhaka during the period from February 2017 to June 2017 to effect of salicylic acid and CaSO on morphophysiology growth and yield of mungbean. In this experiment, the treatment consisted of two mungbean varieties viz. V 1

= BARI mung 4, V = = BARI mung 6 and four different concentration of Salicylic acid (SA) and CaSO

viz. T 0 =control, T 1 =5 mMole CaSO4, T 2 =Salicylic acid 0.5 mMole, T =Salicylic acid 0.5mMole + 5 mMole CaSO4. The experiment was laid out in a two factors randomized complete block design (RCBD) design having three replications. Results showed that a significant variation was observed among the treatments in respect of majority of the observed parameters. The collected data were statistically analyzed for evaluation of the treatment effect. Variety and salicylic acid and CaSO had significant influence on growth, yield and yield components of mungbean. The tallest plant (60.40 cm) was obtained from BARI Mung-6 with Salicylic acid 0.5milimole + 5 mMole CaSO4. The highest number of leaves plant -1 4 (14.33), pod length (9.52 cm), number of pods plant -1 (30.07), number of seeds pod -1 (13.53), thousand seed weight (73.17 g) was obtained from BARI Mung-6 with Salicylic acid 0.5milimole + 5 mMole CaSO4. The lowest number of leaves plant -1 (9.13), pod length (6.25 cm), number of pods plant (22.60), number of seeds pod -1 (11.53), thousand seed weight (36.91 g) was obtained from BARI Mung-4 with control treatment. The highest seed yield ha -1 (1.93 ton) was obtained from BARI Mung-6 with Salicylic acid 0.5milimole + 5 mMole CaSO4 treatment combinations while the lowest seed yield (1.26 ton) was recorded from BARI Mung-4 with control treatment combination. The most of the parameters gave the best performance which was achieved from BARI Mung-6. Again, Salicylic acid 0.5milimole + 5 mMole CaSO4 showed the best performance regarding most of the yield and yield contributing parameters. In case of combined effect, BARI Mung-6 and Salicylic acid 0.5milimole + 5 mMole CaSO4 gave the best result considering yield and yield contributing parameters.
