“…], and rice (Oryza sativa L.) in Senegal. Research has shown that the adoption of adequate soil restoration and management practices and the implementation of climate change adaptation strategies can slow and even reverse the degradation of agricultural production systems (Connolly-Boutin & Smit, 2016;Roudier et al, 2011).…”

Pearl millet [Pennisetum glaucum (L.) R. Br.] yields in Senegal are constrained by rainfall variability, persistent drought, and low soil fertility. Mungbean [Vigna radiata (L.) Wilczek], a short-duration and relatively drought-tolerant legume crop, is capable of improving soil fertility and productivity of associated crops. Our study evaluated the effects of pearl millet and mungbean intercropping on crop yields in the semi-arid regions of Senegal. Field experiments were conducted during the 2017 and 2018 growing seasons at Bambey and Nioro sites located within Senegal's west-central and Saloum agricultural regions, respectively. Experimental treatments: monocropped millet (T 1), monocropped mungbean (T 2 , 100%), and 23% (T 3), 43% (T 4), 47% (T 5), 62% (T 6), 125% (T 7), and 164% (T 8) of mungbean intercropped with millet were laid out in a randomized complete block design and replicated four times. In addition to yield, canopy cover and normalized difference vegetation index (NDVI) were measured and yield advantage was assessed with the land equivalent ratio (LER). Combined millet and mungbean seed yields were up to 60 and 85% higher under intercropping systems compared to millet monocropping at Bambey and Nioro, respectively. Similarly, LER was always greater than unity (> 1) under millet-mungbean intercropping compared to millet monocropping. Mean canopy cover estimates and NDVI values increased by up to 60 and 30% in millet-mungbean intercropping over millet grown alone, respectively. These combined yield gains obtained without fertilizer applications suggested that optimizing mungbean density (62-125%) in pearl millet-based systems can increase the combined yields in a low-input and/or high-risk environment in Senegal.

“…Por otro lado, en la dimensión consumo, por sus beneficios nutricionales las legumbres pueden contribuir a la seguridad alimentaria y nutricional (SAN), en especial entre la población más vulnerable, además forman parte de los sistemas alimentarios sostenibles 19 . Los agricultores familiares pueden consumir y comercializar las menestras que producen y emplear los residuos de los cultivos como forraje para los animales o para fertilizar los suelos y hacer que la tierra sea más productiva, disminuyendo el costo de producción 20,21 . Es así que las legumbres promueven la agricultura sostenible y contribuyen al enfrentamiento a los embates del cambio climático 22,23 .…”

“…41. An evaluation of BNF in food grain legumes grown in experimental plots in Africa revealed high levels of symbiotic dependency on N 2 fixation for their N nutrition (Dakora et al 2015). Cowpea could, for example, derive 30-96 % of its N nutrition from symbiosis, soybean 39-87 %, pigeon pea 27-92 %, groundnut 24-67 %, mungbean 66-86 %, chickpea (kabuli) 3-92 % and chickpea (desi) 21-82 % (Dakora et al 2015).…”

Principles of Plant-Microbe Interactions

Biological nitrogen fixation (BNF) is the process of the reduction of dinitrogen from the air to ammonia carried out by a large number of species of free-living and symbiotic microbes called diazotrophs. BNF presents an inexpensive and environmentally sound, sustainable approach to crop production and constitutes one of the most important Plant Growth Promotion (PGP) scenarios. Here I will summarize various aspects of BNF, including the dinitrogen reduction catalysed reaction carried out by "nitrogenase" and the enzymes/genes involved and their regulation, the inherent "oxygen paradox", the identification of diazotrophs, sustainable agricultural uses of BNF, symbiotic plant-diazotroph interactions and endophytic diazotrophs, data from the field, and future prospects in BNF.
