Abstract

Planting dates for a crop is a non-monetary input but plays a significant role in increasing the yield crop. Therefore, identifying genotype-specific planting dates is essential for obtaining the economic yield of tropical sugar beet. From this perspective, a field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University in Bangladesh, from November 2015 to April 2016. Five sugar beet genotypes: Shubhra, Cauvery, EB-0616, EB-0626, and EB-0809 planted on four dates: 10, 20, 30 November, and 10 December. Treatments were laid out in a split-plot design replicated three times. Data revealed that planting on 10 November date, genotype EB-0809 produced the highest tuber yield, which was significantly superior to any other genotype combined with other planting dates. It was found that every ten days delay of planting from 10 November to 30 December reduced the tuber yield by 30, 43, and 55%, respectively. Results confirmed that planting the EB-0809 genotype on 10 November is ideal to obtain the highest tuber yield of tropical sugar beet in Bangladesh.

旧雅鲁藏布江漫滩热带甜菜(Beta vulgaris L.)基因型块茎最高产量的最佳种植日期

作物的种植日期是一种非货币性投入，但在提高作物产量方面发挥着重要作用。因此，确定特定基因型的种植日期对于获得热带甜菜的经济产量至关重要。为此，我们于2015年11月至2016年4月在孟加拉国农业大学农学田间实验室进行了田间试验。5种甜菜基因型:Shubhra、Cauvery、EB-0616、EB-0626和EB-0809，分别在11月10日、20日、30日和12月10日种植。处理被放置在一个分裂的设计重复三次。数据显示，在11月10日种植，EB-0809基因型块茎产量最高，显著优于其他基因型与其他种植日期的组合。结果表明，从11月10日推迟到12月30日，每推迟10天，块茎产量分别下降30%、43%和55%。结果证实，在11月10日种植EB-0809基因型是获得孟加拉国热带甜菜块茎最高产量的理想选择。
