“…The positive effect of inoculation could be also explained by the fact that these microorganisms are adapted to the pedoclimatic conditions of the environment. In fact, some studies have shown that inoculation can only be effective when the microorganisms are adapted to the environment abiotic conditions (Meddad-Hamza et al, 2010). Our results contrast those of Diatta et al (2013) who did not have a positive impact of inoculation on sesame in the natural environment due to presence of the native microflora.…”

Several studies have clearly demonstrated the scientific and practical use of the symbiotics microorganisms for plants in earth ecosystems. The main goal of this study was to rehabilitate a degraded soil of the sahelian zone of Burkina Faso by using the rhizobia and mycorrhizal symbiosis through the inoculation technique. Native rhizobial strains were isolated from soil samples. These strains were then tested in laboratory and greenhouse conditions for their effects on the nodulation and growth of Vachellia seyal. At the end of these tests three promising strains were selected to form a complex that was used with or without arbuscular mycorrhizal fungus for the inoculation of plants produced in nursery or issued from direct seedling at the field. After 3, 12 and 14 months of cultivation, respectively, the growth parameters of plants such as the height and the collar diameter were measured. In addition, the field survival rate of plantations was evaluated. The results showed that inoculation has improved the growth and survival rate of Vachellia seyal plants in the field. The double inoculation was more effective than the single inoculation. With these promising results, we recommend inoculation of seedlings for a better success of restoration plantings in the Sahel. © 2020 International Formulae Group. All rights reserved.

“…Semelhante ao observado neste trabalho, Meddad-Hamza et al (2010) verificaram que maior taxa de colonização micorrízica em plantas de oliveira (Olea europaea L.) não resultou em maior eficiência na promoção do crescimento vegetal, concluindo que o sucesso da utilização de FMA no processo de aclimatização não depende exclusivamente do percentual de colonização micorrízica, mas da eficiência do fungo. Da mesma forma, Thonar et al (2011) Melo et al 2003), inclusive durante a aclimatização (Yano- Melo et al 1999, Oliveira et al 2010, Oliveira et al 2011.…”

RESUMO O objetivo deste trabalho foi avaliar a eficiência de isolados nativos e exóticos de fungos micorrízicos arbusculares (FMA) na promoção do crescimento de plântulas micropropagadas de Pseudobombax simplicifolium S. Robyns durante a fase de aclimatização. O experimento foi realizado em casa de vegetação em delineamento inteiramente casualizado em três tratamentos de inoculação; Entrophospora etunicata (autóctone), Acaulospora longula (exótico) e um grupo testemunha não inoculado. As plântulas foram aclimatizadas em solo e vermiculita (2:1 v/v) em 10 repetições para cada tratamento totalizando 30 parcelas experimentais. Ao final do experimento, mudas de P. simplicifolium micorrizadas apresentaram melhor desenvolvimento comparado às não inoculadas. Apesar do inóculo com FMA nativo de E. etunicata ter sido mais eficiente em colonizar as plantas, os incrementos na área foliar, biomassa fresca e seca foram similares aos proporcionados pela espécie exótica de FMA (A. longula). Conclui-se que durante a fase de aclimatização, mudas de P. simplicifolium têm o desenvolvimento vegetativo beneficiado pela micorrização, independente da origem dos isolados fúngicos testados nesse estudo.

“…Several benefits of AMF have been reported including improved plant survival and acclimatization, increased growth and nutrient uptake (especially P, Zn, Mn, Mg, Cu, K, and N), increased crop yields (Estaun et al, 2002; Wang et al, 2008; Kapulnik et al, 2010; Ortas, 2010; Kavoo-Mwangi et al, 2013) and improved water use efficiency (WUE; Auge, 2001). These have been reported for plants and crops like olive (Porras-Soriano et al, 2010), banana (Kavoo-Mwangi et al, 2013, 2014), turmeric (Radhika and Rodrigues, 2010) and cassava (Ceballos et al, 2013), and sweet potato (Abdel-Razzak et al, 2013). …”

Combined Application of Biofertilizers and Inorganic Nutrients Improves Sweet Potato Yields

Sweet potato [Ipomoea batatas (L) Lam] yields currently stand at 4.5 t ha−1 on smallholder farms in Uganda, despite the attainable yield (45–48 t ha−1) of NASPOT 11 cultivar comparable to the potential yield (45 t ha−1) in sub-Saharan Africa (SSA). On-farm field experiments were conducted for two seasons in the Mt Elgon High Farmlands and Lake Victoria Crescent agro-ecological zones in Uganda to determine the potential of biofertilizers, specifically arbuscular mycorrhizal fungi (AMF), to increase sweet potato yields (NASPOT 11 cultivar). Two kinds of biofertilizers were compared to different rates of phosphorus (P) fertilizer when applied with or without nitrogen (N) and potassium (K). The sweet potato response to treatments was variable across sites (soil types) and seasons, and significant tuber yield increase (p < 0.05) was promoted by biofertilizer and NPK treatments during the short-rain season in the Ferralsol. Tuber yields ranged from 12.8 to 20.1 t ha−1 in the Rhodic Nitisol (sandy-clay) compared to 7.6 to 14.9 t ha−1 in the Ferralsol (sandy-loam) during the same season. Root colonization was greater in the short-rain season compared to the long-rain season. Biofertilizers combined with N and K realized higher biomass and tuber yield than biofertilizers alone during the short-rain season indicating the need for starter nutrients for hyphal growth and root colonization of AMF. In this study, N0.25PK (34.6 t ha−1) and N0.5PK (32.9 t ha−1) resulted in the highest yield during the long and the short-rain season, respectively, but there was still a yield gap of 11.9 and 13.6 t ha−1 for the cultivar. Therefore, a combination of 90 kg N ha−1 and 100 kg K ha−1 with either 15 or 30 kg P ha−1 can increase sweet potato yield from 4.5 to >30 t ha−1. The results also show that to realize significance of AMF in nutrient depleted soils, starter nutrients should be included.
