Wheat Cultivation in Tangail District of Bangladesh

A survey on 20 farmers’ wheat fields was conducted at 8 villages in Tangail District, Bangladesh in 1987-88 dry season. All of the surveyed fields were under rain-fed conditions. Information on cultural practices was collected using predesigned questionnaires. Observations on plant density and nutritions, and grain yield and yield components were also made at different growth stages. Farmers’ average rates of seeding and applied potassium fertilizer conformed to the recommended ones, but those of applied nitrogen and phosphorus fertilizers were about 60 and 80%, respectively, of the recommended doses. Grain yield varied from 0.83 to 2.34 t/ha and was correlated with numbers of tillers and ears per m2 at the flowering and maturity stages, respectively. Multiple regression analysis for the grain yield indicates that higher plant density did not always increase the grain yield but that the combination of optimum plant density and more tillers per plant could attain higher grain yield in the surveyed fields in Tangail District
