    EFFECT OF MULCH MATERIALS AND POULTRY MANURE ON WEED CONTROL AND YIELD OF WATERMELON (Citrullus lanatusL.)
    (Department of Agronomy, Nasarawa State University Keffi, 2020-06-06) Ibrahim, Abdullahi Jaji; Olutekunbi, A.O.; Mundi, A.D.
    Field trials were conducted during the dry season of 2016 and 2017 at the Teaching and Research Farm of the Faculty of Agriculture, Nasarawa State University, KeffiShabu-Lafia Campus, to determine the influence of mulch materials and poultry manure on weed control and yield of watermelon (Citrilluslanatus L.). The experiment consisted of polyethylene (PE) plastic mulch plus 10 tons/ha of poultry manure (PM), PE plastic plus 5 tons/ha PM, PE plastic alone, hay mulch plus 10 tons/ha PM, hay mulch plus 5 tons/ha PM, hay mulch alone and no mulch plus 0 tons/ha PM (control). The treatment combinations were laid out in a randomized completely block design (RCBD) with three replications. The most abundant weed species in the field were bush tea, torpedo grass, crabgrass and large purple nutsedge and a change in weed composition was observed between treatments. The results revealed that weed control achieved by PE plastic mulch plus 5 and 10 tons of poultry manure was higher than that of the hay mulch only and the combination of hay mulch and poultry manure. Fruit yield was significantly affected by the use of a PE plastic mulch and hay mulch and poultry manure. Application of PE plastic mulch plus 5 tons/ha PM or PE plastic mulch plus 10 tons/ha PM produced the highest fruit yield of watermelon in the study area. However, the number of fruit per plant and fruit per plot did not differ significantly. The use of PE plastic mulch with application of 5 – 10 t/ha of poultry manure could be utilized for sustainable environmental benefits, improvement in yield and weed control efficacy in watermelon.

    Insecticidal Evaluation of Some Botanical Leaf Powders On Cowpea Beetle Callosobruchus maculatus (F.) On Stored Bambara Groundnut (Vigna subterranea (L.) Verdcourt.
    (Department of Agronomy, Nasarawa State University Keffi, 2012-03-03) Mundi, A.D.; Adamu, R.S.; Ajayi, Folorunso A.; Bamayi, L.J.; Egwurube, E.A.
    Two Laboratory trials were conducted at the Department of Crop Protection, Faculty of Agriculture, Ahmadu Bello University, Samaru-Zaria to evaluate the efficacy of five plants species. Anogeissus leiocarpus Guill. and Per., Antidesma venosum Tull., Maranthes polyandra (Benth.) Prance. Mitragyna inermis (Willd.) Kuntze. and Vitex madiensis Olive., for their leaf powders at two levels of concentrations (5.0 and 10.0 g/100 g seed) as protectant against Callosobruchus maculatus F. infesting stored bambara groundnut. Actellic dust 2% at 2.0 g/100 g seed (treated check) and untreated control were placed alongside with these plant powders to serve as checks. Treated and untreated experiments were infested with adult C. maculatus under prevailing storage conditions. Anogeissus leiocarpus, Antidesma venosum and Mitragyma inermis leaf powders at 10 g/100 g seed recorded over 45% adult C. maculatus mortality at 24 hours of treatment. All the plant leaf powders considerably reduced oviposition of C. maculatus as compared to untreated control. Vitex madiensis leaf powder at 10 g/100 g seeds of Bambara groundnut maintained low F1 –F3 progeny emergence for the 12 weeks of observation while Antidesma venosum and Maranthes polyandra all at higher concentration levels maintained low F1 and F2 progeny emergence for 8 weeks of observation. The leaf powders of Vitex madiensis, Antidesma venosum and Maranthes polyandra seem promising in inhibiting progeny emergence of C. maculatus for 2 months of treatment. The Bambara groundnut seed qualities were not adversely affected by the leaf powdered treatments of the botanicals. These plants have potential insecticidal properties which can further be researched upon to serve as alternatives of synthetic insecticide.
