Yields and protein content of two cowpea varieties grown under different production practices in Limpopo province, South Africa

Evaluating the freezing impact on the proximate composition of immature cowpea (Vigna unguiculata L.) pods: classical versus spectroscopic approaches

“…Moreover, the limited data available in the literature concerning the nutritional composition of cowpea pods are referred to the contents of two varieties grown under different farming systems in South Africa, which displayed protein values ranging between 179.0 and 251.0 g kg −1 DW. 23 Hence, even though the protein content observed in the present work was quite similar to the concentration found for cowpea seeds in other previous studies (174.0-303.0 g kg −1 DW), 24 -28 the values presently retrieved for the pods still surpassed those previously reported, reinforcing the relevance of the season, agro-environmental conditions and cultivar on protein content. 23 In addition to preharvest factors, the protein concentration in cowpea pods is also affected by the storage conditions, undergoing a severe decrease due to freezing.…”

“…23 Hence, even though the protein content observed in the present work was quite similar to the concentration found for cowpea seeds in other previous studies (174.0-303.0 g kg −1 DW), 24 -28 the values presently retrieved for the pods still surpassed those previously reported, reinforcing the relevance of the season, agro-environmental conditions and cultivar on protein content. 23 In addition to preharvest factors, the protein concentration in cowpea pods is also affected by the storage conditions, undergoing a severe decrease due to freezing. Hence cowpea pods undergoing 6 and 9 months of storage at −18 ∘ C exhibited a decrease in their protein content by 12.9 and 18.5% on average respectively ( Fig.…”

“…The concentration of CP in fresh pods was in the range 295.0–356.0 g kg −1 dry weight (DW), indicating plant variation concerning this nutritional feature, depending on both the characteristics of the plant under consideration and the specific growing conditions. Moreover, the limited data available in the literature concerning the nutritional composition of cowpea pods are referred to the contents of two varieties grown under different farming systems in South Africa, which displayed protein values ranging between 179.0 and 251.0 g kg −1 DW . Hence, even though the protein content observed in the present work was quite similar to the concentration found for cowpea seeds in other previous studies (174.0–303.0 g kg −1 DW), the values presently retrieved for the pods still surpassed those previously reported, reinforcing the relevance of the season, agro‐environmental conditions and cultivar on protein content …”

Influence of Biofertilizers on Protein, Moisture and Ash Content in Relation to Swelling Property, Water Absorption Capacity, Mineral Elements, Total Phenolic Level of Stevia (<i>Stevia rebaudiana</i> Bert.) Plant Grown under Acidic Soil Zone of South India

“…The higher percent protein content of green pods of Pan 311 variety of cowpea in 2005/06 was due to its early maturity status and better nutrients uptake ability including nitrogen (Sebetha et al, 2010). The earlier studies were reported that % protein in SR aboutmaturity status and better nutrients uptake ability especially nitrogen with applied biofertilizers in combinations.…”

Growth and yield parameters of three cowpea (Vigna unguiculata L. Walp) lines as affected by planting date and zinc application rate

“…Cowpea (Vigna unguiculata L. Walp) is a significant grain and fodder pulse grown around the world. 1,2 It serves as a dual purpose grain legume crop, providing food for human consumption and fodder for livestock. 3 This crop is successful in most regions because of its ability to survive in low fertile soils 4 , and withstand alkaline soils 5 .…”
