    GROWTH AND DEVELOPMENT OF GOMPHRENA CELOSIOIDES MART UNDER SCREEN HOUSE CONDITIONS IN ILORIN, SOUTHERN GUINEA SAVANNA ZONE OF NIGERIA
    (Agrosearch, 2013-12) Takim, F. O.,; Olawoyin, O.K; Olanrewaju., W.A
    The pattern of growth of Gomphrena celosioides Mart (Amaranthaceae), a weed in mown grass and lawn commonly used in southern Nigeria for treatment of skin infections and as abortifacient was evaluated in Ilorin (Lat. 8o 29'N & 8o 30'N; Long. 4o 30'E & 4o 32'E), southern Guinea savanna of Nigeria between 2010 and 2012. Seedlings and soil samples to a depth of 15cm were collected from different locations and enumerated for 15 weeks. G. celosioides seedling had a prolific growth rate, producing many leaves, sparsely branching and excessive flowers within a short period after emergence. The estimated seeds of G. celosioides in soil seedbank were about 885 seeds/m2. The growing shoot increased in length as a function of plant age with a mean absolute growth rate of 0.13 g plant-1 day-1, mean RGR of 0.07 g g-1 day-1. This result will be valuable in aiding the prediction of G. celosioides infestations in agricultural fields and provide a valuable input in timing of its control.
