“…Cowpea (Vigna unguiculata L.) is the most important component of tropical agricultural systems due to its capability to recover marginal lands through nitrogen fixation and as a cover crop (Kebede & Bekeko, 2020). It is considered promiscuous in its association with root nodule-dwelling bacteria, so-called rhizobia.…”

Enumeration of the native rhizobia population is important to determine the abundance of rhizobia in the soil and the achievement of inoculation. In Ethiopia, limited information is available on the population abundance of cowpea nodulating rhizobia. This study aimed to evaluate the population abundance of rhizobia nodulating cowpea and their relation with cropping history and soil properties in cowpea producing areas of Ethiopia. The abundance of rhizobia existing in the soils was assessed by the most probable number technique. The study revealed that the population abundance of rhizobia nodulating cowpea is high, ranging from 3.1 × 10 4 to 1.0 × 10 7 rhizobia cells g −1 of soil, and the population varied at each location. Besides, there was no statistically significant correlation between soil physicochemical properties and the rhizobial population. All the investigated soils had been cropped with cowpea in monoculture (sole cowpea), intercropping (mostly with sorghum and maize) and crop rotation for many years. Thus, the higher rhizobia population observed in this study is associated with the season factor and cropping history of the areas. In general, the soils of cowpea production areas in Ethiopia harbor adequate levels of rhizobia capable of nodulating cowpea, which are passable to provide satisfactory nitrogen fixation and nodulation.

“…It is not surprising therefore that global production of this important staple crop increased from 1 million tonnes in 1971 to 7 million tonnes in 2014, and the yield (kilogram per hectare) increased from 237 to 614 in the same period [1]. The dry grain yields [4] of genetically improved cultivars are the highest in the USA (1790 kg•ha −1 average) and China (1038 kg•ha −1 ), but the lowest in the Sub-Sahara Africa (299 kg•ha −1 ). South Asians, Caribbeans, Latin Americans, and Sub-Saharan Africans consume [1] more cowpeas (33g per capita per day) than Europeans (7g per capita per day).…”

Several potentially practical biochemical processes in plant systems still remain hidden, especially the NADH-glutamate dehydrogenase (GDH) synthesis of nongenetic code-based RNA that optimizes crop nutritious yield by degrading superfluous genetic code-based RNA. In continued characterization of the biochemistry of cowpea grain yield, GDH was purified by electrophoresis from seeds of cowpea treated with solutions of stoichiometric mixes of mineral salts. The GDH was made to synthesize RNAs in the amination (α-KG/NADH/

“…It is considered less sensitive to B deficiency compared to grain legumes [21]. Cowpea (Vigna sinensis L.), a major grain legume with significant nutritive value (i.e., rich in energy, protein and minerals) is grown on 14.5 M ha of agricultural farmlands around the world, yielding 6.2 M metric tons [22][23][24]. B fertilization improved the yield of many crop plants such as Oryza sativa L. [25], Triticum aestivum L. [26], Brassica oleracea L. [27], Vigna unguiculata L. [28], and Zea mays L. [29].…”

Assessing Yield Response and Relationship of Soil Boron Fractions with Its Accumulation in Sorghum and Cowpea under Boron Fertilization in Different Soil Series

Boron (B) is an essential micronutrient in the growth of reproductive plant parts. Its deficiency and/or toxicity are widespread in arid and semi-arid soils with low clay contents. This study was planned to determine the response of sorghum (Sorghum bicolor L., non-leguminous crop) and cowpea (Vigna sinensis L., leguminous crop) to boron (0, 2, 4, and 16 µg g−1) on four distinct soil series from Punjab, Pakistan i.e., Udic Haplustalf (Pindorian region), Typic Torrifluvent (Shahdra region), Halic Camborthid (Khurianwala region), and Udic Haplustalf (Gujranwala region). Overall, there was a significant difference (p < 0.05) in yield between the sorghum (3.8 to 5.5 g pot−1 of 5 kg dry soil) and cowpea (0.2 to 3.2 g pot−1 of 5 kg dry soil) in response to B application. The highest yield was observed in both sorghum and cowpea either in control or at 2 µg g−1 B application in all four soils. Cowpea showed the same yield trend in all four soils (i.e., an increase in yield at 2 µg g−1 B application, followed by a significant decrease at the higher B levels). In contrast, sorghum exhibited greater variability of response on different soils; Udic Haplustalf (Pindorian region) produced the greatest yield at low levels of B application. However, Halic Camborthid produced its lowest yield at that level. Boron concentration in shoots increased with the levels of B application, particularly in sorghum. In cowpea, the plant growth was extremely retarded—and most of the plants died at higher levels of B application even if a lower concentration of B was measured within the shoot. Hot water-extractable B was the most available fraction for cowpea (R2 = 0.96), whereas the easily exchangeable B was most available for sorghum (R2 = 0.90). Overall, these results have implications for micronutrient uptake for both leguminous and non-leguminous crops.
