Abstract
The field experiment on broccoli (Brassica oleracea var. Italica L.) was conducted at Bangladesh Agricultural Research Institute, On-Farm Research Division, Dawlatpur, Khulna during the season 2021-2022 taking five varieties, namely BARI Broccoli-1, Green Crown, Green Giant, Green Carpet, PARATSO to investigate the salt-tolerant varieties for maximizing broccoli yield as well as farmers’ income. The experiment was laid out randomized complete block design with three replications. Among the five varieties the maximum curd diameter (19.00 cm), curd length (16.50 cm) and curd weight (486.67 g) were recorded from V4 (Green Carpet). The yield range of the varieties was 13.65 to 19.46 t ha-1. Variety V4 (Green Carpet) was produced the maximum yield (19.46 t ha-1) followed by V2 (Green Crown) was (18.12 t ha-1). Since the V4 (Green Carpet) and V2 (Green Crown) are suitable for the coastal areas, if this variety is combined with the coastal area cropping pattern then the cropping intensity will increase, which will be beneficial to the farmers economically and meet the nutritional also.
