EFFECT OF SALINITY AT REPRODUCTIVE STAGE IN RICE

A pot experiment was conducted with two rice cultivars viz, Pokkali (salt tolerant) and BRRI dhan 29 (salt sensitive) at the grill house in the Department of Crop Botany, Bangladesh Agricultural University (BAU), Mymensingh. The experiment was conducted to investigate the effect of two salt concentrations, 0 and 200 mM on reproductive growth of two rice cultiver. The experiment was laid out in Completely Randomized Design (CRD) with six replicates. From the investigation it was observed that growth in terms of yield declined due to reductions in panicle length, primary branch no., secondary branch no., filled grain no., thousand seed weight, chlorophyll content, tiller number, filled grain and increase unfilled grain etc.
