Okra is a commercially important vegetable crop that grows in tropical, subtropical, and warm temperate parts of the world, but its productivity is hindered by a lack of improved cultivars and delayed and erratic seedling emergence in the field. An experiment was conducted to evaluate the effect of seed priming treatments on okra genotypes' seedling emergence and fruit yield. In this experiment, Clemson spineless, Arka Anamika, SOH701, 240,207, and 240,586 okra genotypes were primed with tap water, 50% cow urine, 200 ppm GA, and 0.5% KHPO as treatments, and dry seed of each genotype was used as a control. The experiment was conducted in Dire Dawa by irrigation in a randomized complete block design with three replicates. GenStat software was used to analyse all the data collected in this experiment. Genotype and seed priming treatments significantly affected phenology, growth, fruit yield, and yield-related traits, and their interactions affected the above traits, except for days to seedling emergence and fruit number per plant. Genotype Clemson spineless (5.13 days) and seed primed with GA (4.6 days) had the shortest days to 50% seedling emergence, and genotype 240,586 primed with KHPO produced the highest fruit yield per hectare (37.78 t ha). So, farmers in the study area are advised to use genotype 240,586 with KHPO seed priming to increase fruit yield. However, research conducted at one site should be repeated at multiple sites in order to make recommendations that are relevant to the country.
秋葵是一种具有重要商业价值的蔬菜作物，生长于世界热带、亚热带和暖温带地区，但其产量受到缺乏改良品种以及田间幼苗出土延迟和不整齐的影响。开展了一项实验，以评估种子引发处理对秋葵基因型幼苗出土和果实产量的影响。在该实验中，以自来水、50% 牛尿、200 ppm 赤霉素和 0.5% 磷酸二氢钾作为处理，对克莱姆森无刺、阿尔卡·阿纳米卡、SOH701、240207 和 240586 等秋葵基因型进行引发处理，每个基因型的干种子用作对照。该实验在迪雷达瓦通过灌溉采用随机完全区组设计进行，重复三次。使用 GenStat 软件分析该实验收集的所有数据。基因型和种子引发处理显著影响物候期、生长、果实产量和产量相关性状，它们的相互作用影响上述性状，但不包括幼苗出土天数和单株果实数。基因型克莱姆森无刺（5.13 天）和用赤霉素引发的种子（4.6 天）达到 50% 幼苗出土的天数最短，用磷酸二氢钾引发的基因型 240586 每公顷果实产量最高（37.78 吨/公顷）。因此，建议研究区域的农民使用经磷酸二氢钾种子引发处理的基因型 240586 来提高果实产量。然而，在一个地点进行的研究应在多个地点重复进行，以便提出与该国相关的建议。
