“…But with shorter period of association with early maize cultivar, the legumes had some time to compensate for growth and flowering. Similar findings were reported by Santalla et al (1994) for bush bean in Spain, by Kamara et al (2011b) for cowpea in Sudan savanna of Nigeria and by Ewansiha et al (2014b) for cowpea in northern Guinea savanna of Nigeria. In addition, land equivalent ratio showed that intercropping advantage was higher when legumes were intercropped with early maturing maize cultivar than with late maturing maize cultivar.…”

Intercropping is a way to intensify agricultural land use. Cowpea is an important crop in the traditional farming systems in northern Nigeria because it serves to provide food and feed. Although lablab has potential to function in these ways, it remains an underutilized crop because among other factors, there is dearth of information on its incorporation into the system by way of intercropping it with the major cereal crops. A field trial was conducted at Samaru (11º 11'N, 07º 38'E, 686 m asl) in northern Guinea savannah of Nigeria, to evaluate the relative yield and yield components of dual-purpose lablab and cowpea cultivars when gown sole and when intercropped with maize of contrasting maturities. The experiment was laid out in a split-plot design with four replications. The experiment consisted of early maize maturing cultivar (TZE COMP. 5 W) and a late maize maturing cultivar (TZL COMP. 1 SYN). Cropping system (intercropping and sole cropping) was assigned to the main plot and crop cultivar (lablab: ILRI 4612, NAPRI 2 and cowpea: IT89KD-288, IT99K-241-2) was assigned to subplots. Results showed that intercropping cowpea or lablab into early maturing maize cultivar was more productive than intercropping into late maturing maize cultivar for number of pods ( -1 ), meaning that both legumes have potential in providing food and feed with lablab producing more fodder and cowpea more grain. Land equivalent ratio showed that intercropping advantage was higher when lablab and cowpea were intercropped with early maturing maize cultivar (1.34, 1.24) than with late maturing maize cultivar (1.10, 1.15). It is recommended that for higher lablab or cowpea/maize productivity in an intercrop, farmers should intercrop dual-purpose cultivars of these crops with maize of earlier maturities.

“…Performance of cowpea intercropped with cereals is dependent on the growth habit of the cowpea crop. Indeterminate cowpea varieties with spreading growth habit normally performed better than the erect cowpea varieties because they are tolerant to shade (Ewansiha et al, 2014a). Ecological studies carried out by Terao et al (1997) showed that at least 40% of incident light is necessary to grow healthy cowpea plants.…”

“…3). The success of intercropping systems depends much on the interactions between the adapted crop cultivars that form the component crops, available management practices which include plant population and planting date of component crops, and the environmental conditions (Lithourgidis et al, 2011;Ewansiha et al, 2014aEwansiha et al, ,b, 2015a. The practice of a given plant configuration or intercropping system is related to one or more cultural practices.…”

“…In a same row intercropping system trial that involved adapted and improved cultivars of cowpea and maize in the northern Guinea savannah (NGS) of Nigeria, indeterminate cowpea cultivar intercepted more light and produced higher fodder and grain yields compared to semi-determinate and erect cowpea (Ewansiha et al, 2014a). Light interception and fodder and grain production by cowpea was higher when intercropped with extra early and early maize cultivars than with late-maturing cultivar.…”

“…Tamilselvam and Das (1994) studied correlation in cowpea and reported that seed yield per plant was positively correlated with number of branches and pods per plant. Ewansiha et al (2015) reported marked and positive correlation between grain yield and number of branches, number of peduncles, number of pods and fodder yield in cowpea varieties. Based on these findings, breeding for higher number of branches, peduncles, pods or fodder yield will lead to higher yields.…”

The introduction and use of appropriate cowpea varieties in south-south Nigeria may contribute to increased food security, especially in the context of the changing climate and desert encroachment in the country. In the context of evaluating diverse cowpea varieties for the changing environment, the present study involved the evaluation of 94 varieties of cowpea in 2013 and 2014 at Benin City in the rainforest of south-south Nigeria to identify varieties with the potential to contribute to grain or forage production and those with the potential for dual-purpose/multiple use. Grain yields of 0.5-2.0 t ha -1 and biomass (fodder) of 0.9-4.4 t ha -1 were obtained. Thirty-seven varieties that may contribute to grain production, 20 varieties that may contribute to biomass production and 13 varieties with potential for both grain and biomass production were identified. The observed potential to contribute to grain production, feed for livestock and crop residues for soil nitrogen improvement suggests cowpea may be a desirable option for use in mitigating the effect of climate change in the context of shift in crops and animals that can be produced in an environment that is changing.
