Growth and Yield of Different Rice Varieties in Coastal Saline Soil

Abstract

A field experiment was carried out in a slightly to moderately coastal saline soil of the Khulna district. The area is mostly under monocropped practices having cropping intensity of >114%. Topsoil, river and ground water salinity in these area range from 1.7-2.6, 0.25-0.39 and 1.4-3.2 dS/m during July to December respectively. Soil and tidal riv er water salinity doesn’t severely affect the growth and yield of both HYV and local rice varieties in this period. BR-23 performed better growth and yield than BR-30 and local varieties. The degree of yield performance were BR-23>BR-30>Jutabalam>Kachra when the other relevant parameters remained constant
