A field experiment was conducted at the experimental field of Horticulture Department, Sylhet Agricultural University, Sylhet, Bangladesh to find out the suitability of protective structures for sweet pepper (var. BARI mistimorich-1) production during winter season of 2013-2014. Four protective structures viz., polytunnel, polytunnel + net, only net and open field (control) were evaluated for sweet pepper production during winter season under Sylhet condition. Different parameters like plant height, leaf plant-1, fruit diameter, number of fruit plant-1, fruit yield plant-1, individual fruit weight, fruit yield t ha-1 were significantly different among treatments. The highest number of fruits plant-1 was counted from the plants grown under only net structure (13.67) while other treatments were statistically similar. The heaviest individual fruit was observed from the plants of polytunnel + net at each of the harvesting date. Under polytunnel + net protection system had the highest individual fruit weight at 1st, 2nd, 3rd and 4th harvest were 117.00 g, 144.10 g, 148.10 g and 77.0 g, respectively which were closely followed by only net protection system. The sweet pepper from polytunnel + net had the highest fruit diameter (6.13 cm) among the all protective structures. The highest sweet pepper fruit yield (0.82 kg plant-1) from only net which followed by polytunnel + net (0.77 kg plant-1). Benefit cost ratio revealed that production of sweet pepper under protected condition was much profitable than that of open field condition.
