Abstract
Grain yield and water use efficiency of wheat cultivars in relation to different sowing environments were evaluated where seven dates of sowing viz. October 22, 29, November 5, 12, 19, 26 and December 3 in the main plots and three varieties namely PBW 725, HD 3086 and HD 2967 in sub-plots'for three consecutive years were considered. Results revealed that wheat crop sown from October 22 to November 5 had better agrometeorological indices, yield attributes, normalized difference vegetative index and higher water use efficiency resulting in higher grain yield than delayed sowing. Wheat varieties PBW 725 and HD 3086 resulted the lower canopy temperature, higher grain yield along with all the yield attributing characters and agrometeorological indices under Northwestern conditions of India. Bangladesh J. Bot. 52(3): 701-707, 2023 (September)
期刊介绍：
Bangladesh in situated on the north of Bay of Bengal. Climatically it is a humid subtropical country. Most of the land is deltaic plain of two great rivers, the Ganges and the Bhrammaputra and it tributaries. The country has rich diversity of plants. Main crops cultivated are Rice, Jute, Wheat, Maize, Sugarcane, Mustard and different kinds of Lentils. There are a good number of Public and Private Universities and Plant Research Establishments.
Bangladesh Journal of Botany is the official organ of the Bangladesh Botanical Society established in 1972. Since 1972 Bangladesh Journal of Botany is being published regularly. Two issues of the Journal are published, one in June and another in December.
Scientific papers (Full paper and short communication) on any field of Plant Sciences from anywhere in the World are considered for publication in Bangladesh Journal of Botany.
