The present investigation was carried out to study gene action and pattern of inheritance of different traits in cowpea. Two different F3 segregating generation of crosses viz., VBN-1 × RC-19 and KBC-9 × PGCP-6 were studied during summer 2021 using augmented random block design at College of Agriculture, Kalaburagi. Data were recorded on 10 different quantitative traits. Transgressive segregants with values exceeding the better parent were observed in both the F2:3 populations for seed yield. In both the populations, negative skewness was observed for days to initiation of flowering, days to physiological maturity and number of pods/plant whereas test weight exhibited positive skewness suggesting a mild and intense selection would be sufficient to gain maximum genetic-gain in negatively and positively skewed traits, respectively. In both the F2:3 populations, positive kurtosis was observed for number of branches / plant, test weight and dry matter content/plant indicating that these traits are governed by fewer numbers of genes.

The study investigated the phenotypic and genotypic coefficient of variation (PCV and GCV) and heritability estimates for various agronomic and nutritional traits in cowpea (Vigna unguiculata). The analysis aimed to identify traits with optimum variability and heritability, as well as to explore the potential presence of additive genetic variance in specific characteristics. The results revealed that the number of secondary branches, plant height, and leaf length exhibited high estimates of both PCV and GCV, indicating the presence of ample variability for these particular attributes within the population. Additionally, the heritability and genetic advance for the number of secondary branches, plant height, dry fodder yield, leaf length, number of primary branches, leaf width, fresh leaf weight (g), green fodder yield, and fresh stem weight (g) were found to be significant, indicating that these traits were predominantly governed by additive gene action. The findings of this study hold significant implications for future breeding programs and genetic improvement strategies. The identified high heritability and genetic advance for the aforementioned traits suggest that these characteristics can be effectively manipulated through selective breeding to develop improved and high-yielding plant varieties.

The existence of genetic variability within a population is a fundamental requirement for promoting the effectiveness of any breeding operation. The study was carried out at Dr. RPCAU's research farm located in Pusa Samastipur, Bihar, during the kharif season of 2019-20. The objective was to assess the genetic variability among 23 cowpea genotypes (22 genotypes from various locations in the country and 1 check genotype). The study employed a randomised block design, consisting of three replications and a total of fifteen characters were recorded during the study. The analysis of variance (ANOVA) revealed statistically significant mean sum of squares (MSS) values attributed to genotype for all recorded variables, suggesting the existence of a substantial amount of diversity across the cowpea genotypes utilised in the study. In general, the recorded values for the Phenotypic Coefficient of Variation were found to be higher than those for the Genotypic Coefficient of Variation. The study observed high heritability estimates and high genetic advance for various traits, including plant height, number of leaves per plant, stem thickness, leaf-to-stem ratio, dry matter percentage, leaf fresh weight per plant, dry weight of stem per plant, seed yield per plant, and dry matter yield per plant. These findings suggest that the influence of the environment on these phenotypes is minimal. One of the key conclusions drawn from the study is that the direct selection of these traits can be employed to enhance fodder characteristics in cowpea.

Cowpea leaves are lost annually due to infestation and spoilage when being transported to clients and the losses at the local markets are brought on by inadequate postharvest handling procedures and market glut, particularly during peak seasons. High moisture content from the cowpea leaves at harvest stage may contribute to increased spoilage hence lowering quantity and quality. The choice of appropriate harvesting stage and drying method can help to reduce this problem. The aim of this study was to determine the best harvesting stage and efficient drying method that would maintain high leaf nutrient composition. Cowpeas variety M66 was used for the research and the treatments included three harvesting stages (21, 35 and 49 days after sowing [DAS]), three drying methods (open sun, solar dryer and oven. Data was collected on iron, calcium, crude fibre, beta carotene, protein and moisture content. The data was subjected for variance using Statistical Analysis System 9.2 edition and significantly different means separated using least significant difference at 5%. The results indicated significant (p<0.05) differences in moisture, calcium, proteins, beta carotene and crude fibre content in both trials. Harvest stage and drying method did not significantly (p<0.05) influence the iron content. Oven and solar drying methods showed better nutrient and mineral retention in the three harvesting stages when compared to the open sun drying method.

This study conducted in Kerala, evaluated the role of conservation tillage (zero tillage (ZT), minimum tillage (MT), and conventional tillage (CT)) with five treatment combination of potassium (12 kg/ha, 20 kg/ha, 40 kg/ha) and magnesium sulphate (60 kg/ha and 80 kg/ha) on total DMP, physiology and grain yield of the test variety Anaswara (cowpea). In pot culture study, application of K: MgSO4, 10:80 kg/ha resulted in highest total chlorophyll content. While higher chlorophyll a content was obtained with the levels 20:60 kg/ha, and highest total DMP was recorded with the application at 40:100 kg/ha. Different levels of K and MgSO4 nutrition positively influenced 100 seed weight and grain yield, while there found no significant difference on chlorophyll b content, days to flowering, and grains/pod with any of the treatments imposed. Higher values for test weight and grain yield were recorded with K: MgSO4 40:60 kg/ha. In field experiment, tillage practices failed to produce notable difference in chlorophyll a, chlorophyll b, total chlorophyll contents, chlorophyll a/b ratio, grains per pod and test weight. Early flowering (45 DAS) and highest total DMP up to 75 DAS were recorded under CT. ZT produced highest LAI, while highest grain yield was noted under MT practice (734.5 kg/ha). Nutrient treatments failed to produce significant differences in chlorophyll b and chlorophyll a/b ratio. However, application at 40:80 kg/ha produced highest LAI, and higher content of chlorophyll a and total chlorophyll content (1.34 mg/g). K:MgSO4 applied at 40:60 kg/ha recorded highest grain yield. LAI was recorded highest under ZT with K:MgSO4 at 40:80 kg/ha. MT + K:MgSO4 at 40:60 kg/ha reported highest chlorophyll a/b ratio (4.71). K: MgSO4 applied at 40:60 kg/ha produced highest grain yield (806 kg/ha). In interactions, MT + K: MgSO4 at 40:60 kg/ha registered highest grain yield (914.8 kg/ha). Overall, in terms of grain yield, the test crop responded well to MT with application of K: MgSO4 at 40:60 kg/ha.

The current study evaluated the impact of intercropping Cowpea and Moong bean on Maize yield and its constituent parts. Nine different treatments were used in the experiment viz., (T1) sole Maize, (T2) sole Cowpea, (T3) sole Moong bean, (T4) Maize + Cowpea (1:1), (T5) Maize + Cowpea (1:2), (T6) Maize + Cowpea (1:3), (T7) Maize + Moong bean (1:1), (T8) Maize + Moong bean (1:2) and, (T9) Maize + Moong bean (2:1) in a randomized block design with three replications in Kharif season. The findings showed that intercropped plants had greater potential and produced higher values for the majority of the studied criteria, including plant height, chlorophyll meter reading (SPAD) number of cobs plant-1, number of rows cob-1, number of grains row-1, 100-grain weight, and straw and grain yields Intercrop’s seed yields were less in intercropped treatments than sole Maize. (T5) Maize + Cowpea (1:2) was best treatment having highest yield (5915.83 kg ha-1), maximum LER (1.8) and MEY (kg ha-1) (11663.36). This clearly demonstrated the advantages of intercropping Maize with legumes. This is because the leguminous crops can provide additional nutrients to the Maize crop through biological nitrogen fixation (BNF). Additionally legumes can improve the declined soil productivity by enhancing the overall soil conditions like chemical, biological, and physical. The increased availability of nitrogen and enhancement in soil physical, chemical and biological properties can improve Maize growth, leading to higher yield. Additionally it boosts soil conservation by providing more ground cover than mono-cropping.

Background: Vitamin C is a water-soluble vitamin widely distributed in nature, mostly rich in fresh fruits and green leafy vegetables. The amount of Vitamin C in a given food depends on soil condition, climate in their area of growth, storage condition after harvest, and methods of preparation. Much amount of Vitamin C in vegetables is lost during cooking and there are still limited information on the impact of different cooking methods on the vitamin C content in leafy vegetable like cowpea vegetable (Vigna unguiculata). It is upon this background that this study aimed to determine the concentration of Vitamin C in cowpea vegetable when cooked using different cooking methods. Methodology: Vitamin C concentration in a solution of cowpea vegetable cooked by different cooking methods (boiling, steaming and microwave methods) was determined by a redox titration using iodine in the presence of starch indicator. This was conducted at Busitema University, Faculty of Science and Education, Biology Laboratory in Uganda. Results: The study revealed that cooking cowpea vegetable using microwave yields the highest concentration of vitamin C (154.8 mg/L), followed by steaming (142.9 mg/L) and boiling yielding the least concentration of vitamin C (130.4 mg/L). Conclusion: The concentration of vitamin C obtained by the three methods of cooking cowpea vegetable has shown that microwaving method of cooking yields the highest concentration of vitamin C followed by steaming method and finally boiling. Further studies should be done to explain the variation of vitamin C concentration in cowpea vegetable when cooked using the above cooking methods. Similar studies should be conducted on other leafy vegetables which are potential sources of Vitamin C.

Abstract Starch samples from eight legumes cultivars instar of one variety of Vigna unguiculata L. (Cowpea), one variety of Vigna subterrenea V. (Bambara groundnut) and six varieties of Phaseolus vulgaris L. (Common bean), grown in Cameroon were isolated, and their physicochemical and pasting properties were evaluated. The objectives of the study were to investigate the starch properties and processing characteristics of different bean varieties, and to establish the basic foundation of improving the functionality of beans and their starch grown in the region. The result revealed significant differences amongst the properties of the starches. The swelling power of the legume starch isolates put them in the category of highly restricted-swelling starch. This characteristic is desirable for the manufacture of value-added products such as noodles and composite blends with cereals. The pasting properties were determined using a rapid visco analyzer, and various legumes bean starches exhibited different pasting profiles. The high breakdown viscosity (BV) was founded for Cowpea and Bambara groundnut and confirmed their low. ability to resist heat and shear stress when compared to Common bean varieties studies. The factors which influence the pasting characteristics resulting to decrease in peak viscosity (PV), trough viscosity (TV) and final viscosity (FV) of starch are attributed to the interaction of starch with the protein, fat, etc. which depended to their variety.
Resumo Foram isoladas amostras de amido de oito cultivares de leguminosas ínstar de uma variedade de Vigna unguiculata L. (feijão caupi), uma variedade de Vigna subterrenea V. (amendoim Bambara) e seis variedades de Phaseolus vulgaris L. (feijão comum), cultivadas nos Camarões, e suas propriedades físico-químicas e de pasta foram avaliadas. Os objetivos do estudo foram investigar as propriedades do amido e as características de processamento de diferentes variedades de feijão e estabelecer as bases básicas para melhorar a funcionalidade do feijão e do amido cultivado na região. O resultado revelou diferenças significativas entre as propriedades dos amidos. O poder de inchamento dos isolados de amido de leguminosas os coloca na categoria de amido com inchamento altamente restrito. Esta característica é desejável para o fabrico de produtos de valor acrescentado, tais como macarrão e misturas compósitas com cereais. As propriedades de pasta foram determinadas usando um analisador rápido de visco, e vários amidos de feijão leguminosos exibiram diferentes perfis de pasta. A alta BV foi fundada para o amendoim Cowpea e Bambara e confirmou sua baixa. capacidade de resistir ao calor e tensão de cisalhamento quando comparado com estudos de variedades de feijão. Os fatores que influenciam as características colantes resultantes da diminuição do pico de viscosidade (PV), da viscosidade mínima (TV) e da viscosidade final (FV) do amido são atribuídos à interação do amido com a proteína, gordura, etc., que dependem da sua variedade.

ABSTRACT: This study evaluated the variability and characterizedthe spatial dependence between some soil attributes in the Eastern Cariri microregion of Paraíba,and analyzed the spatial correlations in order to identify the interactions between such attributes in cowpea bean(Vigna unguiculata L. Walp)production. Harvest data of the agricultural years of 2000-2017 in the Eastern Cariri microregion of Paraíba were analyzed. Parameters of the fitted models wereestimated using the Maximum Likelihood method and the performance of the models was evaluated based on coefficients of determination(R2), maximum log-likelihood function, and Schwarz's Bayesian information criterion (BIC). Correlation and spatial autocorrelation between the cowpea productivity and agrometeorological elements was detected through the spatial analysis, using techniques such as the Moran's index I. The study showed that, according to the performance indicators used, the spatial error model offered better results in relation to the classical multiple regression models and the self-regressive spatial models, indicating that the inclusion of spatial dependence in the models improves the estimate of productivity of cowpea in the microregion of Cariri Oriental da Paraíba.
