“…Given the polygenic nature of grain yield, its value is deemed acceptable for the crop, as it is greatly influenced by the edaphoclimatic conditions of each evaluated environment (Sousa et al 2019). Studies conducted on cowpea by Silva et al (2016) and Araújo et al (2022) have found similar results, with CV values for yield of 24.26% and 25.44%.…”

“…The analysis groups the additive effects of genotypes with the multiplicative interaction effects and subjects them to principal component analysis. The which-won-where biplot is efficient in showing the performance of the best genotypes in their respective environments and can form target mega-environments for the crop (Araújo et al 2022).…”

The objective of this study was to identify cowpea genotypes that fulfill the criteria of high grain yield, adaptability, and stability in the Mato Grosso do Sul (MS) region. Yield data from Value for Cultivation and Use (VCU) trials conducted in the municipalities of Dourados and Aquidauana/MS from March to August 2017 and 2018 were used, totaling four environments. A randomized block design with 14 treatments and four repetitions was adopted. Yield was evaluated by weighing the grains from the usable plot and converting the values to kilogram per hectare. After the analysis of variance, the interaction between genotypes and environments was evaluated by the methodologies of adaptability-stability analysis of Eberhart and Russell, Lin and Binns modified by Carneiro and GGE-Biplot. The genotypes Pingo-de-ouro 1-5-7, Pingo-de-ouro 1-5-5 and Bico-de-ouro 1-5-24 are stable, adaptable and productive for the state according to the complementary use of the methods.

“…Cowpea [Vigna unguiculata (L.) Walp.] is a legume species of great agronomic potential due to its wide adaptability to diverse environmental conditions, low production costs and high nutritional value (Boukar et al 2019, Araújo et al 2022, Raina et al 2023. The crop has been cultivated in more than 100 countries, mainly between 40º N and 30º S latitudes, and it is expected to fulfill dietary requirements under the current changing climate (Gonçalves et al 2016).…”

We investigated the genetic control of the three yield components in cowpea: number of grains per pod, pod length and grain size, in a biparental cross. Genetic parameters were estimated in generations of a cross between two contrasting genitors, using a randomized complete block design with three replications. Narrow-sense heritability estimates varied from 27% to 67%, suggesting that genetic gains can be achieved with selection. Pod length and grain size had the highest heritability values and genetic gains. The number of grains per pod is highly affected by the environment. Dominance was detected for all traits, mainly for pod length. However, additive gene effects accounted for more than 68% of the variation in all traits, which are controlled by at least 10 genes. It is possible to improve the evaluated traits via conventional breeding approaches, although large population sizes will be required in breeding stages.

“…Cowpea (Vigna unguiculata L. Walp) is a foremost legume food grown around the world (Musa et al, 2017) as food for human consumption (Mfeka et al, 2019).The grains are highly valuedfor food, and the fodder and haulm used to feed livestock during the dry season (Lan gyintuo et al, 2003;Mfeka et al,2019). A moderate cheap and willingly available source of pr otein and minerals, and contains high concentrations of iron (Fe) and zinc (Zn) (Belarmino et al, 2013;Rouault, 2015;Araújo et al, 2022). An average ripe seed of cowpea contains 22% protein, 1.4% fat, 59.1% carbohydrate, and 3.7% ash, an energy value of 340 kcal/ 100g (Putul et al, 2021).…”

Plant growth analysis is today studied as it relates to change in capture and efficiency in the use of resources rather than as it relates to relative growth rate in the past. Net assimilation rate (NAR) is the rate of increase in dry matter over unit area of leaf, which represented a measurement of excess of photosynthesis overrespiratory losses of dry matter. Two field experiments were conducted at the Faculty of Agriculture and Agricultural Engineering Research Farm of Abubakar Tafawa Balewa University, Bauchi, North Eastern, Nigeria, between 2006 and 2007 to evaluate the influence of phosphorus (0, 25, 50 kg P/ha) and zinc levels (0, 2.5, 5 kg Zn/ha) on NAR of six cowpea varieties namely: IT90K 277, IT93 455 1, IT89KD 288, IT97K 568 18, IT90K 82 2 and Kanannado. Results obtained showed that NAR was not significantly influenced by P and Zn levels and therefore, 0 kg ha1 SSP and Zn rate produced the highest NAR than higher levels. Neither applications of each of P and Zn at higher levels or their interactions, nor did year or variety were found to have significant effects on NAR; but rather NAR is being determined by number of factors such as nutrient supply, photosynthesis rate, etc and these are never fixed or constant and hence a particular factor e.g., nutrient (P or Zn) cannot dictate NAR alone.
