摘要
在本尚古尔-古木兹州阿索萨地区的土土上，研究了播种率和行距对油菜产量和产量构成的影响。三个水平的种子率(5、10和15 kg hm -1)与三行间距(15、20、25 cm)和另外一块以25 kg hm -1撒播tef种子作为标准对照，共10个处理。他们被放置在一个阶乘RCBD中，有三个重复。试验地点记录了施用处理对tef籽粒产量的显著影响。每公顷施用种子10公斤，行间距25厘米，籽粒产量最高(1216.8 kg hm -1)。籽粒产量从973.8 kg ha-1显著提高到1216.8 kg ha-1，播种量从25 kg ha-1下降到10 kg ha-1，这是由于分蘖体有足够的空间而导致的。在研究区，10 kg种子每公顷、25 cm间距是获得最佳籽粒产量的较适宜措施。
Influence of Seed Rate and Row Spacing on Growth and Yield of Tef ( Eragrostis tef) Production at Assosa, Benishangul-Gumuz Regional State, Western Ethiopia
The effects of seed rate and row spacing on yield and yield components of tef (Eragrostis tef) were studied on the Nitisols of Assosa, Benishangul-Gumuz Regional State. Three levels of seed rate (5, 10 and 15 kg ha-1) factorially combined with three rows spaces (15, 20, 25 cm) and an additional plot of broadcast of tef seed at 25 kg ha-1 as a standard check making a total of 10 treatments. They were laid out in a factorial RCBD with three replications. Significant influence on the grain yield of tef due to treatment application was recorded on trial locations. The maximum grain yield (1216.8 kg ha-1) was obtained from application of 10 kg seed per hectare and 25 cm spacing between rows. Grain yield highly significantly increased from 973.8 to 1216.8 kg ha-1 with decrease in the seed rate from the broadcast 25 to 10 kg ha-1 due to the fact that tef tillers, as there is enough space. 10 kg seed ha-1 with 25 cm spacing would be more suitable practices for attaining optimum grain yield for tef at the study area.
