“…For instance, calculating the leaf size as LA over leaf number, Black eye bean leaf size exceeded that of the small leaf producing variety-White wonderer trailing by 39%. In agreement with this result, Pereira et al (2019), Peksen et al (2005) and Bisikiwa et al (2014) reported a difference in leaf growth among cowpea varieties including leaf number and area. The improved LAI observed for the Black eye bean variety could be associated with its higher LA and the strong positive (r ¼ 0.99, p ¼ 0.001) correlation between LA and LAI (Table 5).…”

Supplying nitrogen to crops through selecting high N fixing legumes and effective inoculant is one of the key strategies to improve crop productivity. However, studies related to the effect of Bradyrhizobial inoculation on leaf growth, its functioning in relation to photosynthesis, and transpiration efficiency (WUE) of cowpea [ Vigna unguiculata (L.) Walp] varieties in the tropics were inadequate. A two-year field experiment was conducted at three sites to evaluate the effect of inoculation on leaf growth, gas exchanges and photosynthetic efficiency of cowpea varieties. The study treatments were composed of four varieties, Keti (IT99K-1122), TVU, Black eye bean, and White wonderer trailing and three levels of inoculation (non-inoculated or inoculated with Bradyrhizobium strains CP-24 or CP-37). Gas exchange was measured on live plants at 67–77 days after sowing, between 8:00 to 11:00 a.m. and 14:00 to 16:00 p.m. Leaf growth parameters (leaf number and leaf area) were measured by destructive sampling, and the yield data was determined by harvesting plants in the three central rows at physiological maturity. Variety TVU performed best in terms of leaf number, photosynthesis rate, and WUE. Whereas, Black eye bean revealed superior performances for leaf area, leaf area index, and stomatal conductance compared with the rest two varieties. The effect of inoculation was significant with 14.0, 23.8, 13.7, and 11.0% advantage in leaf area, leaf area index, net photosynthesis, and WUE, respectively. Moreover, the performance of cowpea of the 2018 cropping season showed a relative advantage over 2019 in terms of leaf number, leaf area, leaf area index, net photosynthesis, and stomatal conductance. Therefore, inoculating cowpea varieties with effective Bradyrhizobium strain can be a viable alternative to enhance growth, gas exchange, photosynthetic efficiency, and grain yield.

“…Similar findings were reported by Sharawy and El-Fiky (2002), Dhanassekar and Pandev (2005), Sheela and Gopalan (2006) in cowpea genotypes for NLP, LA, leaf/stem ratio and leaf crude protein content. Analyzing local cowpea genotypes in Turkey, Peksen et al (2005) observed in contrast that there was no statistically difference in terms of leaf area.…”

Aims: Cowpea's use as leafy vegetable has been widely neglected in research. The present study was aimed at finding out the nature and magnitude of genetic variability in dual-purpose cowpea for leaf yield and quality attributes. Place and Duration of Study: Ngaoundéré University (Cameroon), from 2008 to 2009. Study design and Methodology: Fourteen pure lines and ten F 1 hybrids derived from a 5 x 5 half-diallel cross were grown in Randomized Complete Block Design (RCBD) with three replications to assess the genetic mechanism of leaf yield index (LYI), leaf area (LA), leaves per plant (NLP), leaf protein (LN) and phosphorus (LP) content.Results: Analysis of variance indicated significant differences (p<0.01) among genotypes for all traits. Moderate to high heritability in broad-sense (0.49-0.90) was recorded for the characters indicating major role of genetic variance in the expression of these polygenic traits. Diallel analysis showed significance (p<0.05) of the effects of general combining ability (GCA), specific combining ability (SCA), the involvement of additive and dominance genes. These genes were asymmetrically distributed among the parental genotypes. Dominant genes had an overall positive effect for leaves per plant, leaf yield index and phosphorus content while high protein content and surface area appeared to be associated

“…The leaf area was determined according to Erkut et al [24] using this formula: SF = 0.67* (L1*W1) + (L2*W2) + (L3*W3), where SF = leaf area; L1 = length of leaf blade 1; L2 = length of leaf blade 2; L3 = length of leaf blade 3; W1 = maximum width of leaf blade 1; W2 = maximum leaf blade width 2 and W3 = maximum leaf blade width 3. Maximum leaflet width (W) (at the widest point perpendicular to the midrib) and length (L) (from lamina tip to the point of petiole intersection along them).…”

“…Taking into account the nutritional importance of this plant, it is, therefore, necessary to solve the fertility problem of Adamawa soils, to improve the P. vulgaris productivity. Adamawa farmers most often use chemical fertilizers for common bean cultivation [6][7][8][9]. However, the use of chemical fertilizers presents an immediate beneficial effect on crop growth and provides an immediate solution to solve fertility problems, but their high cost and unavailability make them almost inaccessible to small farmers.…”

Aims: Amendment of ferralitic soils of Ngaoundere (Cameroon) by rock materials, so-called petrofertilizer, can be a promising solution to improve their fertility and thus enhance crop yield. Study Design: In the present study, the influence of pyroclastic powder on the growth of the common bean (Phaseolus vulgaris L.) was assessed. Place and Duration of Study: Department of Biological Sciences. The sowing was done on June 13, 2017 until 2 septembre. Methodology: An experimental design with four (04) different treatments was implemented: 0 g per pot (0% of pyroclastic: the control), 150 g per pot (10% of pyroclastic: P10 Treatment), 300 g per pot (20% of pyroclastic: P20 Treatment) and 450 g per pot (30% of pyroclastic: P30 Treatment). The pyroclastic powder was applied at three different (03) stages: sowing, germination, and flowering stage. All the treatments were irrigated with 250 ml of water once every 3 days during the growing stage. Results: Growth parameters, seed yield, and seeds nutritional values were measured. Results revealed that seeds yield from the treated pot using 30% of pyroclastic powder is 4.2 times greater than that of the control. Globally, pyroclastic powder improved the nutritional values of common bean seeds compared to the Control. Fertilizing the soils at the sowing stage significantly (p<0.05) improves the values of the studied growth parameters. The protein content of seeds from treatment at the sowing stage was 1.05 and 1.11 times greater than that from treatment at germination and flowering stages. Conclusion: The application of 30% of pyroclastic powder at the sowing stage is recommended for the cultivation of the common bean in the Adamawa (Cameroon).
