EFFECT OF SALICYLIC ACID TO MITIGATE SALT STRESS IN CHILLI

Abstract

A pot experiment was conducted in the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, during the period from November 2016 to April 2017. The two factors experiment was laid out in Completely Randomized Design with four replications. Factor A was different levels of salinity induced by sodium ii 0 : 0 ds/m, S :8 d/sm, S 3 :12 ds/m, S :16 ds/m and factor B was different concentration of Salicylic Acid viz. A 0 : 0 mM, A 1 4 : 0.5 mM, A : 1 mM. The experimental results showed that different levels of salinity significantly affects the morphological characters, yield contributing characters and yield of chilli plants. The higher levels of salinity showed greater reduction of growth, development and yield component to control. The highest plant height, branch number/plant, leaf chlorophyll content as measured in SPAD value, leaf area, canopy size, fruit length and breadth/plant, number of flower and fruit/plant and yield 2 and lowest . For treatment combination, the maximum yield/plant 0 A 0 2 whereas the lowest value from S 4 A . Finally, this result suggests that application of salicylic acid can effectively reduce the deleterious effect of salt stress in chilli.
