Abstract: The present study allowed to characterize at agro-morphological level, eight (08) traditional cowpea accessions from Benin and Ghana in order to identify the best performing ones. The test was installed in a Randomized Complete Block (RCB) design with four (04) repetitions in a station in Savè in Center-Benin. The parameters studied are the date of flowering and maturation, the numbers of stems and leaflets per plant, the height of plants, the port of the stem, the lengths of pods and petiole, the weights of pods, tops, seeds and of 100 seeds, the seed yield, the colors of flowers, pods and seeds, the shapes of leaflets and of seeds, the size and the appearance of seeds. Xlsat version 2018.6 software was used for multi-component analysis to categorize accessions by their significant variables. SAS 9.2 software was used for the analysis of variance and the comparison of the means of variables. The number of branches, the length of the petiole, the height of the plants, the number of leaves, the length of the pods, the weights of the pods and of the tops had a positive influence on the cowpea seeds yield. The accessions were classified into three groups. The first group is made up of three (03) high-performance accessions, Nketewade, Mung bean lens and Songotra, with a short cycle of 61 to 62 days and a high yield of between 1050 kg/ha and 1300 kg/ha. The second group is that of the Djetoko and black eye bean accessions of long-cycle from 80 to 88 days, with a yield of between 620 kg/ha and 800 kg/ha. The third group is made up of false Cassoulet, Ennepa and Nsroma accessions with a short cycle of 62 to 65 days and a low yield of between 175 kg/ha and 230 kg/ha. Multilocal tests and genetic molecular characterization must be considered for a good valuation of these cowpea accessions.

Abstract: This study was conducted to test the agglutinating properties of leaf crude extracts of selected plants on human A-B-O blood group. The experimental plants used were as follows: kasapi-sapi (Ageratum conyzoides L.), Vicks (Origanum vulgare L.), Sabi (Chenopodium ambrosioides L.), Dunggaw (Bryophylum pinnata L.). The blood types of the 90 blood donors were pre-determined using the commercially available anti-sera A and B. Each blood samples were tested with the four plant leaf crude extracts for the agglutination reaction and were examined under the microscope. Presence of agglutination of red blood cells was marked as positive and absence of such reaction was marked as negative. The result had shown that kasapi-sapi (A. conyzoides L.) and Sabi (C. ambrosioides L.) did not cause agglutination of red blood cells in any of the human blood types. Dunggaw (B. pinnata L.) and Vicks (O. vulgare L.) leaf crude extracts did cause agglutination of the red blood cells from the donors, but, not to a specific blood type. Thus, none of the experimental plants could serve as a substitute for commercially produced anti-sera but could serve as first aid during emergency cases to stop excessive bleeding.

Abstract: Shallot (Allium cepa var. ascalonicum Backer) is an important vegetable crop cultivated by smallholder farmers for consumption and income generation in Ethiopia. However, scarcity of high yielding varieties as well as lack of superior planting material seriously constrains productivity of the crop. Research project was initiated aiming at studying adaption of true seed shallot for yield and components. A series of experiments were conducted using the randomized complete block design to identify the appropriate variety for production of bulb yield. The combined analysis of variance results for marketable bulb yield (kg/plot), unmarketable bulb yield (kg/ha), total bulb yield (kg/plot) and total bulb yield (t/ha). The results showed that the mean squares for main factors of genotype and year as well as interaction of genotypes x year were significant for marketable bulb yield (kg/plot). The overall marketable yield range of the shallot varieties was from 256.56- 171.49qtha-1 and the average number of splits per plants ranged from 8- 4.72. Improved Minjar shallot variety showed its superiority in marketable bulb yield (kg/plot), total bulb yield (kg/plot) and total bulb yield (t/ha) yields as compared to other varieties. Therefore, as there was no significant yield advantage between these varieties from true seed study area, so the experiment could be repeated across locations to come up with good conclusion for recommendation.
