Bell pepper (Capsicum annuum L. var. grossum Sendt.) production is often constrained by prevailing sub-optimal temperature conditions. The treatments that enhance earliness and extend availability period may substantially increase value of the crop. This two-year study (2010-11 and 2011-12) was conducted to investigate the comparative effect of two growing environments (open field vs. polyhouse), three planting dates (15 October, 30 October, and 15 November), and four mulch treatments (black polythene, clear polythene, paddy straw, and no-mulch) on growth and yield of bell pepper. The highest fruit number, fruit weight, early yield, marketable yield, and total yield were obtained when the crop was planted in the polyhouse on 30 October under black polythene mulch. Thus, the use of polyhouse and black plastic mulch, when combined with appropriate planting date, improves early and total yields of bell pepper in areas where the production is constrained by sub-optimal temperature conditions.
