摘要

对小麦品种的谷物产量和水分利用效率与不同播种环境的关系进行了评估，考虑了连续三年的七个播种日期，即主田的 10 月 22 日、29 日、11 月 5 日、12 日、19 日、26 日和 12 月 3 日，副田的三个品种，即 PBW 725、HD 3086 和 HD 2967。结果表明，与延迟播种相比，10 月 22 日至 11 月 5 日播种的小麦作物具有更好的农业气象指数、产量属性、归一化差异植被指数和更高的水分利用效率，因而粮食产量更高。在印度西北部条件下，小麦品种 PBW 725 和 HD 3086 的冠层温度较低，谷物产量较高，所有产量属性特征和农业气象指数也较高。孟加拉国植物学杂志52(3):701-707，2023 年（9 月）

Grain yield, heat and water use efficiency of wheat cultivars in relation to different sowing environments

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.

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.
