“…Ageratum conizoides, Borreria ocymoides and Mariscus alternifolius were found to be predominant. This agrees with earlier study by Yakubu et al (2006) and Karaye et al (2007) who reported that several weeds and crops are site specific, while others will flourish over a broad array of habitat.…”

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.

The spacing pattern and growth habit of juvenile oil palm during the early stages of field establishment have often led to serious weed problem until canopy closure at subsequent years.This study was carried out during the rainy season of 2016 to evaluate the weed species composition and diversity of an intercrop between 2-year-old oil palm tree and two fruit vegetables at an oil palm plantation in Ala, Akure-North Local Government, Ondo state, Nigeria. Two accessions of tomato (NGB 01665 and NG/AA/SEP/09/053) and eggplant (NGB 01737) were intercropped within the alley of immature oil palm. Weed sampling was carried out using 0.25 m 2 quadrat within each experimental plot. Quantitative analysis of weed species parameters and Simpson's Diversity Index were evaluated. The result revealed that 28, 21 and 20 weed species were found across all the plots at 3, 6 weeks after intercropping (WAI), and after harvesting respectively. Members of Asteraceae produced the highest weed species at 3 WAI (17.857%); Poaceae recorded the highest weed species at 6 WAI and after harvesting (19.048% and 20%) respectively. A total of 23, 16 and 15 broadleaves were found at 3 and 6 WAI, and after harvesting. In all the juvenile oil palm/vegetable intercrops evaluated, the control plot recorded the highest weed species richness at 6 WAI, when compared to other intercropping regimes. The control and juvenile oil palm/tomato (NGB 01665) intercrop plot recorded the highest and lowest Simpson's Indices of Diversity at 6 WAI (0.877 and 0.734) respectively.

Knowledge of distribution, density, and abundance of weed in a place is a prerequisite for its proper management. Parthenium hazard is a national agenda in Malaysia, and Kedah is the worst infested state in the country. Despite it, the distribution and abundance of the weed is not systematically documented. Periodical weed surveys were conducted at Kuala Muda, Kedah, during March and September 2015 to identify infested locations, to determine density, abundance, and severity of infestation, and to do mapping of weed distribution of the area. Geographic locations were recorded using a GPS. Weed density was measured following the list count quadrat method. e mapping of weed infestation was done by the ArcGIS software using data of GPS and weed density. Different letters were used to indicate the severity of infestation. Results indicated that in Kuala Muda, sixteen sites are infested having average weed density of 10.6 weeds/m 2 . e highest density was noted at Kg. Kongsi 6 (24.3 plants/m 2 ). e relative density was highest at Semeling (27.25%) followed by Kg. Kongsi 6 (23.14%). e average severity of infestation was viewed as the medium. Parthenium abundance and relative density increased by 18.0% and 27%, respectively, in the second survey conducted. e intervention of concerned authority to tackle the weed problem using integrated weed management approach is emphasized.
