This study was conducted during the rainy season of 2017 within the alleys of juvenile oil palms that were 2-year-old at the oil palm plantation located in Ala, Akure-North Local Government, Ondo State. Tomato accessions (NGB 01665 and NG/AA/SEP/09/053) were intercropped at 1, 2 and 3 m from the juvenile oil palm within the alley in a randomized complete block design. The results showed that tomato (NGB 01665 and NG/AA/SEP/09/053) planted at 3 m from the juvenile oil palm performed better than those at other planting distances in terms of growth and yield attributes with number of fruit; fruit weight and yield per hectare of 39.50, 2265.8 g and 3.74 ton/ha respectively. However, the control (sole) recorded the best yield but was not significantly different from those planted at 3 m from the juvenile oil palm. Varietal advantage was recorded by tomato (NGB 01665) with higher number of fruits, fruit weight and yield per hectare (26.94, 1834 g and 3.158 ton/ha) respectively. Intercropping advantage was not recorded for any of the intercropping distance regimes during the trial (when the juvenile oil palms were 2-year-old), with LER values less than unity.

尼日利亚热带雨林区少年油棕-番茄间作中两种番茄对三种距离模式的生理响应

这项研究是在2017年的雨季期间，在位于Ondo State Akure-North Local Government Ala的油棕种植园的2岁幼小油棕小巷内进行的。番茄种（NGB 01665和NG / AA / SEP / 09/053）在胡同内的幼虫油棕处分别以1个，2个和3 m的空间套种。结果表明，在距幼油棕3 m处种植的番茄（NGB 01665和NG / AA / SEP / 09/053）在生长和产量以及果实数量方面，表现优于其他种植距离。果实重量和每公顷产量分别为39.50、2265.8 g和3.74吨/公顷。但是，对照（单一）的单产最高，但与距幼油棕3 m处的对照无明显差异。番茄（NGB 01665）记录了品种优势，其果实数量，单果重和每公顷产量分别更高（26.94、1834 g和3.158吨/公顷）。在试验期间（当少年油棕为2岁时），没有任何套间距离方案记录套间优势，而LER值小于1。
