“…The lower nodule per plant for local variety interaction with row spacing in compare with nasir and goberesha interaction with all tested row spacing might be from nature of the variety. Also Kouyate et al. (2012) reported, variety can affect nodule number.…”

This study evaluated the effect of row spacing on growth, yield and yield components of common bean varieties at Jimma. The objectives of the study were (i) to evaluate the best performed common bean variety (ii) to determine the optimum row spacing for different common bean varieties under the test environment. The experiment was laid out in randomized complete block design (RCBD) in factorial arrangement with three replications. A combination of three common bean Varieties (Nasir, Goberesha and Local Asendabo) and row spacing at four levels (30, 40, 50, 60cm) were used as experimental treatments. Leaf number was significantly varied between the varieties; whereas row spacing significantly influence leaf area index. The main effect of row spacing and the interaction effect did not show significant influence on both. Hundred seed weight and number of seed per pod were varied between the varieties and row spacing. Hundred seed weight was increased with row spacing. Pod number per plant, nodule number per plant, grain yield and harvest index was significantly affected row spacing, variety and their interactions. Grain yields increased with plant population assuming a parabolic curve to the plant density of both determinate varieties at 40cm row spacing. The highest yield for variety-Nasir and variety-Goberesha were observed at40 cm row spacing; whereas the highest yield for the local variety was recorded at 50 cm row spacing.

“…Among the genotypes, LT yielded more dry biomass and this could help farmers to improve the soil fertility status if selected to be used in rotation systems at both sites. Rotation of crops increases the production of biomass necessary to the improvement of the low level of soil organic matter (Zoumana, Tatiana, Inamoud & Marc, 2012).…”

Nitrogen is a major plant nutrient which is most limiting in the soil due to soil losses of mineral nitrogen (N) form. To ensure availability of nitrogen in the soil, the study was conducted to screen four cowpea genotypes for Biological Nitrogen Fixation (BNF) and their contribution to maize yield in maize- cowpea rotation. The cowpea genotypes used were mutants LT11-3-3-12 (LT) and BB14-16-2-2 (BB) and their parental varieties Lutembwe (LTPRT) and Bubebe (BBPRT) respectively. Trials were established at two sites (Chisamba and Batoka) of different soil types. The Randomized Complete Block Design (RCBD) with three replications was used. Labelled 15N urea was applied at 20kgNha-1 on the four cowpea genotypes during 2015/16 growing season. Cowpea plant parts were dried and milled for 15N isotopic analysis. The data collected included Nitrogen content and atom % 15N excess in the fixing cowpea genotypes and non-nitrogen fixing pearl millet to determine total nitrogen derived from the atmosphere (TNdfa) and total nitrogen (TN) in plant parts which were further used to compute Biological Nitrogen Fixation (BNF). The results showed that BNF by cowpea genotypes at Chisamba was 63.9 kg ha-1 and was significantly (P<0.001) more than BNF of 6.6 kgha-1 at Batoka. The LT mutant fixed significantly (P<0.001) higher nitrogen of 86.1 kgha-1 and 16.5kg ha-1 at Chisamba and Batoka respectively than other genotypes. However, both BB and LT mutants significantly fixed more nitrogen than their parents and have demonstrated to increase maize grain yields up-to 12 tha-1 in the maize – cowpea rotation.

“…Higher number of leaves under monocropping and rotational cowpea may have been attributed to fertility of soil (Pereira vaz Ferreirra et al, 2015) that led to increase in growth of cowpea (Abraha, 2013). The production of more leaves under monocropping and rotational cowpea means higher light interception and more photo-assimilate production (Babaji et al, 2011;Kouyate et al, 2012). Blade et al (1992) reported that cowpea growth was severely depressed by competition with other plants.…”

Cowpea is a multi-purpose nitrogen fixing crop that can be grown as a vegetable, grain legume and a fodder. The objectives of this study were to investigate the growth response of cowpea to different cropping systems at different locations and determine nitrogen fertilization on cowpea growth and soil organic carbon content. Three cropping systems were used, namely, maize-cowpea rotation, cowpea monocropping and maize-cowpea intercropping at three locations (Potchefstroom, Taung, and Rustenburg) in South Africa during 2011/12 and 2012/13 planting seasons. Nitrogen fertilizer was applied at two rates where no application was the control at all locations and application according to soil analysis recommendation for maize requirement was applied at each location. The variables measured for cowpea growth were days to 100% flowering and physiological maturity, number of leaves and nodules per cowpea plant. Soil organic carbon was determined for each treatment. The results showed that, maize-cowpea rotation and monocropping reached days to 100% flowering and maturity significantly earlier compared to intercropping. Cowpea planted at Potchefstroom and Rustenburg reached days to 100% flowering and physiological maturity significantly earlier than cowpea planted at Taung. Cowpea planted at Taung had significantly higher number of nodules per plant than cowpea planted at Potchefstroom and Rustenburg. There was also a positive correlation between soil organic carbon and cowpea growth. It is concluded that the positive effect of cowpea in agronomic systems is enhanced by the correct cropping system, although it is affected by location.
