Many farmers spend a lot of money in the control of weeds during the long juvenile phase of oil palm. Intercropping is a popular practice employed by farmers to increase productivity of wide alley and overcome weed problem. However, improper intercropping of Elaeis guineensis with other crops has impaired the growth and development of the oil palm due to competition for environmental resources. The study was conducted to investigate the impact of intercropping on the growth of juvenile oil palm for 2 years. The research commenced during the rainy season of 2016 at an established juvenile oil palm plantation in Ala, Akure-North Local Government of Ondo State. Four fruit vegetables were intercropped separately within the alley of the plantation at 1, 2 or 3 m away from the oil palms in a randomized complete block design. Growth parameters of intercropped and non-intercropped juvenile oils were compared. Results of the study revealed that at 16 weeks after intercropping (WAI), the intercropped oil palm recorded better growth performance with higher values of canopy spread, number of frond, number of leaflets and trunk height (218.20, 37.00, 87.48 and 38.17 cm) respectively, than the sole oil palms (214.67, 32.83, 72.89 and 31.67) respectively. There was no significant difference in all the growth parameter examined except canopy height at (P<0.05) level of significance. Juvenile oil palm cultivated in rainforest agroecological zone of Nigeria can be intercropped with fruit vegetables without any deleterious effect when intercropped at minimum of 1 m away from the oil palms.

尼日利亚雨林地带水果蔬菜间作油棕(Elaeis guineensis Jacq。)的生长评估

在油棕树的幼年期,许多农民花了很多钱来控制杂草。间作是农民采用的一种普遍做法,可以提高宽胡同的生产力并克服杂草问题。然而,由于对环境资源的竞争,杜鹃花与其他农作物间作不当已经损害了油棕的生长和发育。进行了这项研究以调查间作对2年间青少年油棕生长的影响。该研究始于2016年的雨季,地点在Ondo州Akure-North地方政府Ala的一个成熟的青少年油棕种植园。在种植园的小巷中,在距油棕树1、2或3 m处分别套种了四种水果蔬菜,采用随机完整块设计。比较了间作和非间作幼油的生长参数。研究结果显示,在套种(WAI)后第16周,套种的油棕表现出更好的生长性能,冠层传播值,叶形数,小叶数和树干高度更高(218.20、37.00、87.48和38.17 cm)分别高于唯一的油棕(214.67、32.83、72.89和31.67)。除了在显着性水平为(P <0.05)的冠层高度外,所有检查的生长参数均无显着差异。在尼日利亚的雨林农业生态区种植的少年油棕,如果与油棕之间的距离至少为1 m,则可以与水果蔬菜一起套种,而不会产生有害影响。研究结果显示,在套种(WAI)后第16周,套种的油棕表现出更好的生长性能,冠层传播值,叶形数,小叶数和树干高度更高(218.20、37.00、87.48和38.17 cm)分别高于唯一的油棕(214.67、32.83、72.89和31.67)。除了在显着性水平为(P <0.05)的冠层高度外,所有检查的生长参数均无显着差异。在尼日利亚的雨林农业生态区种植的幼年油棕,如果与油棕之间的距离至少为1 m,则可以与水果蔬菜一起套种,而不会造成任何有害影响。研究结果显示,在套种(WAI)后第16周,套种的油棕表现出更好的生长性能,冠层传播值,叶形数,小叶数和树干高度更高(218.20、37.00、87.48和38.17 cm)分别高于唯一的油棕(214.67、32.83、72.89和31.67)。除了在显着性水平为(P <0.05)的冠层高度外,所有检查的生长参数均无显着差异。在尼日利亚的雨林农业生态区种植的幼年油棕,如果与油棕之间的距离至少为1 m,则可以与水果蔬菜一起套种,而不会造成任何有害影响。小叶数目和树干高度(分别为218.20、37.00、87.48和38.17厘米),比唯一的油棕(分别为214.67、32.83、72.89和31.67)高。除了在显着性水平为(P <0.05)的冠层高度外,所有检查的生长参数均无显着差异。在尼日利亚的雨林农业生态区种植的幼年油棕,如果与油棕之间的距离至少为1 m,则可以与水果蔬菜一起套种,而不会造成任何有害影响。小叶数目和树干高度(分别为218.20、37.00、87.48和38.17厘米),比唯一的油棕(分别为214.67、32.83、72.89和31.67)高。除了在显着性水平为(P <0.05)的冠层高度外,所有检查的生长参数均无显着差异。在尼日利亚的雨林农业生态区种植的幼年油棕,如果与油棕之间的距离至少为1 m,则可以与水果蔬菜一起套种,而不会造成任何有害影响。
