Abundance and Diversity Index of Weeds in Oil Palm and Vegetable Intercropping in Rainforest Zone of Nigeria
Ayodele Samuel Oluwatobi and Kehinde Stephen Olorunmaiye
Universitas Sebelas Maret
The problem of severe weed infestation often arises during the early phases of establishment of oil palm field due to the spacing requirement and growth habit of young oil palm plantation until later years when the canopy closes. This study was conducted at Ala, Akure-North Local Government Area, Ondo State, Nigeria, to investigate the composition of weed species and their distribution in fruit vegetable-juvenile oil palm intercrop. The fallow alleys within the immature oil palm were intercropped with 2 accessions of tomato (NGB 01665 and NG/AA/SEP/09/053) and eggplant (NGB 01737). The sampling of the weed species was carried out with a quadrat (0.25 m2). Weed species parameters and the Diversity Index (D) were quantitatively analyzed. The results revealed that members of Asteraceae and Poaceae gave the highest weed species at 3 and 6 weeks after intercropping (WAI) (17.857% and 19.04%) respectively. A total of 23 and 16 were found at 3 and 6 WAI, while the least diversity index of 0.734 was recorded in the immature oil palm/tomato (NGB 01665) plot at 6 WAI. Farmers should be persuaded to simultaneously intercrop fruit vegetables within the alley of juvenile oil palm, particularly at the earlier years prior to closure of the oil palm canopy.

Growth assessment of juvenile oil palm (Elaeis guineensis Jacq.) intercropped with fruit vegetables in a rainforest zone of Nigeria

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 the juvenile oils were assessed. Results revealed that at 16 weeks after intercropping (WAI), the intercropped oil palm recorded better growth performance with higher 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 cm) respectively. There were no significant difference in all the growth parameters examined except canopy height (p < 0.05). 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.

Abstract The present study characterizes seed-related traits, phytochemical, physiochemical parameters and fatty acid profile of shea (Vitellaria paradoxa) seeds collected from the Kosubosu, Fufu and Sare areas of Kwara State, Nigeria to determine the effects of microclimate on seed morphology, biochemical and oil constituents. Seed morphological data were analyzed for variability. Seed oil was extracted for phytochemical constituents, physicochemical properties, and fatty acid profiling by gas chromatography equipped with mass spectrometry (GC/MS). Results showed intra and inter-locational variations in seed characters. Most fruits had 1–2 seeds. Seeds were predominantly brown and very few were dark brown. Phytochemicals and physicochemical parameters of the seed oil varied with place of collection. Alkaloid, saponin, tannin and phytate contents ranged between 0.79–0.84, 1.20–1.26, 1.48–1.56 and 0.15–0.18 mg g−1 respectively. The density of the oil was less than that of water, acid value ranged from 10.58–13.56 mg KOH g−1 and iodine values were between 36.63 to 40.32 g I2 (100 g)–1. Saponification values lie between 160.39 and 184.14 mg KOH g−1; and free fatty acid was within 5.32–6.81 %. Peroxide, ɑ-tocopherol, total phenol and oxalate values as well as viscosity of the oil also varied; however, refractive index was similar. Ethyl oleate and octadecanoic acids were present and most abundance in all the locations, while glycidol stearate was only found in Fufu samples with three other fatty acids. Five fatty acids were present in Kosubosu, while Sare had only two. The results obtained in the present study indicate that shea oil could be used for medicinal, nutritional and industrial purposes. Since seed characters, phytochemical, physicochemical and fatty acid compositions varied with the microclimate, environmental and micro-ecological conditions should be considered when collecting seeds for oil utilization.

A field experiment was conducted at the botanical garden of the University of Ilorin to determine the effects of weed density and distance on the growth and yield of two varieties of okra (NHAe-40 days and Kirikoi). The experiment was a complete randomized block design with eleven treatments and three replicates. The treatment details include T0 = No weed, T1 = One weed per plant T2= Two weeds per plant, T3 = Three weeds per plant, T4 = Four weeds per plant, T5 = Five weeds per plant, T6 = Six weeds per plant, T7 = Seven weeds per plant, T8 = Eight weeds per plant, T9 = Nine weeds per plant and T10 = Ten weeds per plant. Data were collected on plant height, number of leaves, stem girth, shoot Fresh and dry weight as well as yield parameters was carried out at the end of the experiment. The result depicts a significant decrease in the vegetative growth and yield parameters with increasing weed density in both varieties. Irrespective of the weed distance, all yield parameters decreased significantly with increasing number of co-habiting weeds except for plant co-habited with one weed at 20 cm and 30 cm weed distance which was significantly the same with the control in both varieties. The result is an indication that absence of weed or early control of weed should be done at the early weeks of growth before the onset of flowering if maximum production is expected.
