    Sorghum (Sorghum bicolor [L.] Moench) Growth and Yield As Influenced by Weed Infestation, Spacing and Number of Plants/Stand in the Southern Guinea Savanna of Nigeria
    (2015 Beth-Bekka Academic Publishers Ltd, 2015-12-18) Emmanuel O. Imoloame
    Field trials were conducted at the Teaching and Research Farm of the College of Agriculture, Kwara State University, Malete, Nigeria, during the 2012 and 2013 cropping seasons. The aim was to determine the effects of plant spacing and number of plants per stand on weed infestation and yield of sorghum in the southern Guinca savanna of Nigeria. The treatments consisted of three plant spacings at 90 x 60 cm, 75 x 50 cm and 75 x 25 cm, which were allocated to the main plot, while the number of plants per stand, namely: 1 plant, 2 plants 3 plants, 4 plants, 5 plants and 6 plants/stand were allocated to the sub-plots, making a total number of 18 treatments. These treatments were laid out in a split plot arrangement fitted into a randomized complete bock design with three replicates. Parameters measured include weed cover scores, weed dry matter, plant height, 1000-seed weight and grain yield. Results showed that wider plant spacings supported weed infestation that were significantly higher than narrower spacings, though it produced significantly highest grain yield. Number of plants/stand had no significant effect on grain yield. Therefore, spacing at 90 × 60 cm and 1- 6 plants/stand are suitable for the production of higher yields of sorghum in the southern Guinea savanna of Nigeria.

    WEED BIOMASS AND PRODUCTIVITY OF OKRA (ABELMOSCHUS ESCULENTUS (L) MOENCH) AS INFLUENCED BY SPACING AND PENDIMETHALIN-BASED WEED MANAGEMENT
    (University of Belgrade, 2018-09-18) Emmanuel O. Imoloame; Muinat Usman
    Field trials were conducted at the Teaching and Research Farm of the Kwara State University, Malete, Nigeria, to determine the effect of plant spacing and weed control methods on weed infestation, growth and yield of okra during the 2016 and 2017 cropping seasons. The experiment consisted of twelve treatments comprising six weed control methods and two plant spacings. The method of weed control consisted of pre-emergence application of pendimethalin at 1.0 kg a.i. ha-1 , pendimethalin at 2.0 kg a.i. ha-1 , pendimathalin at 1.0 kg a.i. ha-1 + one supplementary hoe weeding (SHW) at 6 weeks after sowing (WAS), two hoe weedings at 3 and 6 weeks after sowing (WAS), weeding at 4 and 8 weeks after sowing (WAS) and a weedy check. The plant spacings were 60cm x 30cm and 60cm x 50cm. These treatments were laid out in a randomized complete block design (RCBD) with split plot arrangements and three replications. Weed control and plant spacing treatments were allocated to the subplots and the main plot respectively. Results showed that a plant spacing of 60cm x 30cm minimized weed infestation and resulted in a higher total number of pods/plot and okra fresh weight, while pendimethalin at 1.0 kg a.i. ha-1 + one supplementary hoe weeding at 6 WAS minimized weed infestation in the plots, and led to the highest total number of pods and yield of okra. This combination also promoted higher economic returns.

    WEED INFESTATION AND PRODUCTIVITY OF MAIZE/SOYBEAN INTERCROP AS INFLUENCED BY CROPPING PATTERNS IN THE SOUTHERN GUINEA SAVANNA OF NIGERIA
    (University of Belgrade, 2018-02-28) Emmanuel O. Imoloame; Kafayat B. Ahmed
    Field experiments were conducted during the 2015 and 2016 cropping seasons at the Teaching and Research (T & R) Farm of the College of Agriculture, Kwara State University, Malete, to determine the effect of cropping patterns on weed infestation, growth and yield of a maize/soybean intercrop in the southern Guinea savanna of Nigeria. The experiments consisted of six treatments as follows: one row of maize alternated with one row of soybean (1:1), one row of maize alternated with two rows of soybean (1:2), two rows of maize alternated with one row of soybean (2:1), two rows of maize alternated with two rows of soybean (2:2), sole maize (1:0) and sole soybean (0:1). The treatments were laid out in a randomized complete block design with three replicates. Data collected were subjected to analysis of variance and means were separated by the least significant difference (LSD) at the 5% level of probability. Results showed that sole soybean consistently suppressed weeds and resulted in a higher yield. Similarly, the 2:1 ratio of maize to soybean did not only reduce weed density, it produced significantly higher yields of maize and lower yield of soybean, and had the higher land equivalent ratio and economic returns followed by sole maize.
