    Opis:
    Experiments to determine the effect of seed size, watering interval and defoliation on growth and dry matter attributes of seedlings of shea butter tree were conducted at Makurdi, Nigeria, from July 2010 to April, 2012. In the first experiment, treatments were made up of three seed size categories described as small (5-10g), medium (11-15g) and large (16-20g) and three watering intervals of 3, 6 and 9 days. In the second experiment, treatments comprised three watering intervals of 3, 6 and 9 days and three levels of defoliation – 0, 50 and 100%. In both experiments, factorial combinations of the treatments were laid out in completely randomized design (CRD) and replicated three times. Results of analysis of variance showed that in the first experiment seed size significantly influenced root length with the medium and large seeds producing seedlings with comparatively longer roots than the small seeds. The most frequently watered seedlings (3 and 6 days) produced more leaves than those watered less frequently (9 days). Seed size influenced dry weight of root and total (whole plant) dry weight with the medium and large seeds recording significantly higher values than the small seeds. Watering interval however did not significantly influence any of the other traits. Seed weight exerted significant influence on amount of dry matter partitioned to the stem and the root. More dry matter was partitioned to the stem by the small seeds. Conversely, medium and large seeds allocated more dry matter to the root than to the stem. In the second experiment, defoliation level only influenced total fresh weight, dry weight of root and total dry weight in favour of plants with half their leaves removed. None of the traits examined were significantly influenced by watering regime. Interaction between defoliation level and watering regime significantly influenced total fresh weight, dry weight of root and total dry weight. Generally seed size had more influence on seedling characters than watering interval. Seedlings also demonstrated remarkable ability to overcome effects of defoliation.

    Opis:
    A survey on the utilization potentials of Moringa oleifera in Nigeria was conducted in 2011. The survey involved 14 states (including the Federal Capital Territory) across the five agroecological zones. The 14 States were Borno, Kano, Adamawa, Kebbi, Kaduna, Niger, Nassarawa, Abuja (F.C.T), Kogi, Benue, Kwara, Oyo, Enugu and Anambra. A semi-structured questionnaire and field visits were adopted in this study while a multistage random sampling technique was used in selecting the respondents. The survey found more than 25 local names of Moringa oleifera in Nigeria. Widespread utilization of Moringa as food was observed with its use as vegetable in soup, as salad or herbal tea having particularly high scores. There was low awareness of Moringa oleifera as a domestic cleansing agent although about 30% of respondents used it in domestic water clarification. The species has high ethno-medicinal value, addressing close to 20 conditions including typhoid and malaria fever (78.7%), ear infection (71.8%), eye infection (66.9%), lowering of blood sugar (diabetes mellitus) (65.2%) and blood pressure (64.7%). It is evident that this important species is still underutilized in Nigeria and more efforts are required for a fuller exploitation of its rich potentials.

    Opis:
    A field experiment was conducted from July to October, in years 2014 and 2015 at the Research Farm, University of Agriculture, Makurdi, Nigeria, to evaluate the yield response of maize-sesame intercrop as influenced by planting densities of sesame and varieties of sesame, as well as to assess the yield advantages of the intercropping system. The factorial (3 x 3) combinations of the treatments were randomly arranged in a split-plot design, with four replications. The varieties of sesame (Ex Sudan, SN 603 and E-8) into maize constituted the main plots, while the planting densities of sesame (66,666, 88,888 and 133,333 plants ha-1 equivalent) into maize were assigned to the subplots. Results of study showed that intercropping maize with sesame variety ‘Ex Sudan’ produced the highest grain yield for maize and highest seed yield of 0.45 t ha-1 and 0.33 t ha-1 respectively, in years 2014 and 2015 for sesame. Sesame sown into maize at the density of 66,666 plants ha-1 produced the highest maize yield of 3.6 t ha-1 and 3.8 t ha-1 respectively, in years 2014 and 2015 and highest sesame yields in both years. Intercropping sesame variety ‘Ex Sudan’ into maize at the density of 66,666 plants ha-1 also gave the highest total intercrop yields, highest land equivalent coefficient (LEC) values, highest land equivalent ratio (LER) values of 1.83 and 1.80, highest percentage (%) land saved, lowest competitive ratio and lowest aggressivity. The implication of study showed that it is most advantageous having both crops in intercrop when sesame variety ‘Ex Sudan’ was sown into maize at the density of 66,666 plants ha-1. This should therefore be recommended for Makurdi location, Nigeria.
