SALT STRESS MITIGATION BY SEED PRIMING IN FABA BEAN (Vicia faba L.)

Abstract

A pot experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from October 2017 to April 2018. The experiment consisted of two factors: Factor A: Different level of saline in soil with NaCl solution such as, S : Control (0 mM NaCl), S 2 : 40 mM NaCl, S 3 : 80 mM NaCl, S 4 1 : 120 mM NaCl and Factor B: Different type of seed priming , viz. P 1 : Non primed , P 2 : Hydroprimed and P : Ascorbic acid priming (100 mg/L). The experiment was laid out in completely randomized design with 3 replications. Salinity level and different type of seed priming showed significant variation with most of the parameters. In case of salinity the total pod weight per plant was recorded highest (90.19 g) from S

while the lowest from S (17.34 g). For priming total pod weight per plant was recorded highest (66.29 g) from P 4 3 while the lowest from P (37.99 g). For combined effect total pod weight per plant was recorded highest (107.09 g) from P 3 S 1 while the lowest from P 2 S 4 1 (16.41 g). So, the use of ascorbic acid priming (100 mg/L) in lowest level of salinity S (0 mM NaCl) was the best for growth and yield of faba bean. 1 3 1
