Cowpea Variety

A field experiment was conducted to examine the effect of plant spacing on grain and fodder yield of four cowpeas varieties. Four cowpea varieties i.e. Asetenapa, Asomdwe, Hewale and Videza were sown with three plant spacing i.e. 30 x 15 cm, 45 x 15 cm and 60 x 15 cm at Samboligo in the Bongo District of the Upper East of Ghana.  The experiment was laid in randomized complete block with four replicates in factorial fashion. Cowpea variety and plant spacing significantly influenced grain yield, 1000 seed weight, nodules per plant and plant height. Plant spacing had no significant effect on stem girth, pods per plant, pod length and seed per pods. Variety ‘Hewale’ produced the highest grain yield of 991.3 kg ha-1 while Asetenapa produced the highest fodder yield of 1025.5 kg ha-1. Interactive effect between Asomdwe and 45 x 15 cm had the highest 1000 seed weight (170.6 g) while Asetenapa and 30 x 15 cm produced the highest grain yield (1072.9 kg ha-1). Variety ‘Hewale’ is recommended for commercial grain production while Asetenapa for fodder production. Asetenapa and 30 x 15 cm combination is recommended for commercial grain production.

Forty five hybrids derived from a diallel mating design of ten parents and one standard check PUSA CHARI-121 were evaluated for general and specific combining ability effects and standard heterosis for grain yield/plant, dry fodder yield/plant, days to 50 per cent flowering, plant height, number of leaves/plant, leaf length, leaf breadth and 100- seed weight of Sorghum bicolor. The mean square due to general and specific combining ability was significan for Days to 50% flowering, Days to maturity, Plant height (cm),No of Leaves/plant, Leaf length (cm), Leaf width (cm), seed yield/plant (g), Fodder yield/plant (q/ha) and 100-seed weight (g) for all the characters. Both additive and non additive genetic effects were present in the material under study. However the ratio of σ2gca/ σ2sca suggested that the preponderance of non additive gene action in expression of all the characters under study. Out of the nine parents PUSA CHARI-121, PANT CHARI-4, MP CHARI, PANT CHARI-6 and PANT CHARI-5 identified as good general combiner for grain yield/plant, dry fodder yield/plant and other agronomical traits. The hybrid HC-136 x PANT CHARI-4 and PANT CHARI-4 x PUSA CHARI-121 for grain yield/plant and hybrid MP CHARI x PANT CHARI-6, PANT CHARI-5 x SPV 1616 and HC-136 x PANT CHARI-4 for dry fodder yield/plant exhibited higher magnitude of positive significant specific combining ability effect with highest standard heterosis and per se performance. These hybrids were also found suitable for two or three yield contributing traits. In general, close association between specific combining ability effects and standard heterosis was observed among the best hybrids identified on the basis of specific combining ability effects for grain and dry fodder yield.

Fodder Yield

The scope of increasing the cultivated area under forages is rather limited, because of mounting pressure on need for food and commercial crops, but there is a large demand for green and dry fodder from livestock industry. Hence, fodder production has to be increased per unit area per unit time. By practicing the de-topping in commercial grain maize we can increase the fodder production, quality and it also reduces the deficit of fodder to some extent. Reviews indicated that by de-topping of maize, there may be slight reduction in grain yield of maize but by doing it at right stage/time and at right plant height it gives highest net returns than no de-topped treatments. De-topping at 30 days after silking; removing the top 6 leaves or after physiological maturity; removing all the leaves above the cob or de-topping above 10th internode gives highest fodder yield and net returns with slight or no reduction in grain yield.

A field experiment was conducted comprising two varieties of mungbean, BARI Mung-5 (V1) and BARI Mung-6 (V2), and five levels of phosphorus fertilizer: triple super phosphate [Ca(H<sub>2</sub>PO<sub>4</sub>)] viz. T1 (control), T2 (42.5 kg P ha<sup>−1</sup>), T3 (85 kg P ha<sup>−1</sup>), T4 (127.5 kg P ha<sup>−1</sup>), and T5 (170 kg P ha<sup>−1</sup>). The experiment was organized in a randomized complete block design with three replications. V1 produced the highest number of pods per plant (7.65), whereas the maximum 1,000-seed weight (49 g) was produced by V2. The maximum plant height (30.89 cm), number of branches per plant (8.55), number of leaves per plant (19.05), number of pods per plant (10.25), pod length (8.95 cm), number of seeds per pod (9.11), 1,000-seed weight (48.17 g), and yield (1.05 t ha<sup>−1</sup>) were obtained from the T4 treatment. The interaction of phosphorus levels and varieties had a considerable effect on the growth, yield, and yield attributes of mungbean. The highest number of leaves (20.44) and number of pods (10.39) were obtained from V1 when 127.5 kg P ha<sup>−1</sup> (T4) was applied, whereas the maximum number of seeds per pod (9.25) and maximum pod length (9.09 cm) were obtained when  85 kg P ha<sup>−1</sup> and 42.5 kg P ha<sup>−1</sup>, respectively, were used. The highest number of branches per plant (8.87), 1,000-seed weight (52.83 g), and the maximum seed yield (1.14 t ha<sup>−1</sup>) were achieved from the treatment V2T4 owing to the interactive effect of phosphorus dose and mungbean variety.

Cowpea is an African legume that was introduced to Brazil by Portuguese settlers in the mid-16th century. The productive potential of this crop may fluctuate depending on its environment. The objective of the present study was to select cowpea lines with high grain yield coupled with other traits of agronomic interest, such as good adaptability and stability, by the GYT biplot methodology. Twelve lines were evaluated in the years 2016 and 2017 in the municipality of Bom Jesus de Itabapoana, Brazil, in a randomized-block design with four replicates and two cultivars, which were used as controls. The following variables were evaluated: number of days to flowering, final stand, crop value, lodging, pod weight, pod length, seed number per pod, seed weight per pod, 100-seed weight (100SW), and grain yield. Analysis of variance was performed and GYT biplots were constructed using R software and the ggplot2 package. The GYT biplot graph analysis allowed for the selection of superior cowpea genotypes. In the combinations of traits observed, lines L1, L3, L5, L6, L8, and L9 were superior and cultivar Imponente stood out as one of the controls. The yield combinations GY*CV, GY*NDF, GY*LDG, GY*CV, GY*PW, GY*SNP and GY*P100G were positively correlated with each other but showed negative to highly negative correlations with GY*SWP and GY*TS.

Thirty genotypes of winged bean were grown in five diverse environments in Papua New Guinea in order to estimate the genotypic, environmental and genotype-environmental variance of grain yield and pod number per plant, seed number per pod, 20-seed weight, pod length and shelling percentage. A maximum grain yield of 2200 kg ha-1 was realized. Environmental and genotypic variance contributed 69.9 and 0.3% respectively to the overall variance of grain yield. A significant genotype x environment interaction for grain yield was adequately explained by joint regression analysis. Correlation studies emphasized the importance of testing genotypes in both the highlands and lowlands. Variation in grain yield was largely due to fluctuations in pod number. Grain yield and pod number showed strong negative genetic correlations with seed number per pod, 20-seed weight and pod length.

Cowpea Variety

Many cowpea varieties (Vigna unguiculataL. Walp) have been proposed by research in Mali. None of these varieties were investigated for their symbiotic potential in terms of root nodulation and mycorrhizal infection. An experiment was conducted at Cinzana Research Station, from 2007 to 2009 with an objective to identify a cowpea variety with high symbiotic potential which may improve millet/cowpea cropping global production. Randomized complete block (RCBD) design with a factorial combination of 3 cowpea varieties (IT89KD-374, CZ1-94-23-1, and CZ11-94-5C) and 2 cropping systems (millet/cowpea intercropping and cowpea-millet rotation) was used. On farm test was conducted to evaluate CZ11-94-5C and IT89KD-374 nodulation performance. Cowpea variety CZ11-94-5-C had the highest nodule number and nodule weight. Millet/cowpea alternate rows intercropping (1/1), only, had a significant influence on cowpea root infection rates by mycorrhizae, on the 45th day after emergence. IT89KD-374 gave the best cowpea grain yield (1540 kg ha−1) in sole crop. The highest millet grain yield (1650 kg ha−1) was obtained under CZ11-94-5C-millet rotation. Farmers' fields assessments results confirmed CZ11-94-5C performance on research station. The CZ11-94-5C cowpea variety needs to be more characterized.

Abstract Cowpea (Vigna unguiculata) is an important tropical legume crop contributing significantly to food security in tropical regions. The present study was carried out to determine the extent of genetic variation, to estimate character associations, heritability and genetic advance of 25 quantitative traits in 30 genotypes of cultivated Vigna unguiculata from the western highland region of Cameroon. These quantitative traits were selected among cowpea descriptor lists. For all these traits, the analysis of variance showed significant difference among genotypes, highlighting the existence of important genetic divergence among the studied accessions. The highest phenotypic and genotypic coefficient of variation was observed in grain yield, pod yield and 100 seed weight. Genetic advance of these three characters was also the highest. Broad sense heritability was high in general, with 20 traits out of 25 having heritability values greater than 70%. This high heritability indicates little influence of the environment on these characters in cowpea. The highest heritability was recorded for 100 seed weight (98.15%) and the lowest for shoot weight (41.38%). At 0.05 probability level, grain yield correlated significantly with 21 out of the 24 other quantitative traits. Among others, grain yield correlated positively and significantly with 100 seed weight, number of pods per plant, number of branches per plant, number of nodes per plant, plant height, plant width, pod length, pod width, seed length, seed width and number of seeds per pod. These positive correlations between grain yield and many other traits indicate that a selection program based on any of these traits will result in increasing yield. Cluster analysis using UPGMA method revealed five distinct clusters. Genotypes named KEBCP025, KEB-CP006, KEB-CP098, KEB-CP070, and more importantly KEB-CP054 and KEB-CP004, were grouped in a single cluster and were characterized by a significantly higher grain yield, pod yield, number of pods per plant, number of seed per pod, plant height, pod length and pod width compared to other clusters. Accessions KEB-CP036 and KEB-CP031 produced significantly more important fresh biomass. These genotypes could be used as parents in genetic improvement programs aiming to increase yield and fresh biomass in cowpea.

Three maturity types of maize, Abontem (extra early maturing), Omankwa (early maturing) and Obaatanpa (medium maturing) were evaluated at three different plant densities 66,667 plants ha-1, 100,001 plants ha-1 and 133,334 plants ha-1  to determine the optimum plant density for grain and fodder yield. The experiment was laid   in randomized complete block with four replicates factorial fashion. The maize maturity type had significant influence on all the traits measured. Plant density had significant effect on cob width, grain and fodder yield but no significant influence on plant height, days to 50% anthesis and silking, anthesis and silking interval, cob length and 1000 grain weight. Obaatanpa (medium maturing) was the maize maturity type that produced the highest grain yield (3139 kg ha-1) and fodder yield of (4173 kg ha-1).  Obaatanpa with 133,334 plants ha-1 interaction produced the highest grain and fodder yield with 3186 kg ha-1 and 4240 kg ha-1 respectively. Obaatanpa with 133,334 plants ha-1 would be recommended for commercial grain and fodder production because the high yielding potential as observed in the study.
