Scoping the potential uses of beneficial microorganisms for increasing productivity in cotton cropping systems

Abstract

a b s t r a c tThere is a growing body of evidence that demonstrates the potential of various microbes to enhance plant productivity and yield in cropping systems. Realizing the potential of beneficial microbes requires an understanding of the role of microbes in growth promotion, particularly in terms of fertilization and disease control, the underlying mechanisms and the challenges in application and commercialization of plant growth-promoting (PGP) microbes. This review focuses specifically on the use of PGP microbes in the cotton industry and summarizes the commercial bioinoculant products currently available for cotton; highlighting factors that must be considered for future development of PGP microbial products for the cotton industry. Given the paucity of information on beneficial microbes for cotton production systems in comparison to those for other cropping systems (e.g. legumes and grains), a snapshot of the current research is critical in light of the increased interest in cotton inoculants, mainly in developing countries such as India, and the overall increased interest in PGP applications as part of promoting sustainable agriculture.

The interdisciplinary nature of <i>SOIL</i>

“…The rhizosphere is rich with microorganisms (Cardon and Whitbeck, 2007) and nutrients, and exhibits a gradient in oxygen concentrations. Plant-growth-promoting rhizospheric (PGPR) microbes contribute to biofertilization, biocontrol, and phytostimulation (reviewed by MartinezViveros et al, 2010;Pereg and McMillan, 2015). The sustainability of crop production systems is a key issue for ensuring global food security.…”

Isolation and selection of plant growth-promoting bacteria associated with sugarcane

“…Many of these mutualistic organisms can act as biofertilizers, increasing the efficiency of nutrient absorption by the plant and producing substances that promote growth. It is estimated that biofertilizers could reduce the use of common fertilizers by 50 % with no yield losses (Pereg & McMillan 2015, Suman et al 2016, in addition to increasing tolerance to abiotic and biotic stresses by promoting biological control (Babalola 2010). In general, microorganisms involved in optimizing plant growth are denominated plant 1.…”

Predicting parameters of degradation succession processes of Tibetan <i>Kobresia</i> grasslands

“…Therefore, the vegetation cover plays a fundamental role in the soil development and soil erosion (Cerdà, 2002;Keesstra et al, 2014), and soil degradation (Ziadat and Taimeh, 2013), and also in the geomorphological (Nanko et al, 2015) and hydrological behavior of the Earth system (Keesstra, 2007;Gabarrón-Galeote et al, 2013) and their interactions with the biota (Araújo et al, 2014;Bochet et al, 2015). At the same time, plants can shape soil microenvironments through living roots (Bardgett, 2002;Puente et al, 2004;Cerdà, 2002;Dai et al, 2013;Keesstra et al, 2014;Shang et al, 2014;Keesstra, 2014;Gabarrón-Galeote et al, 2013) and affect microbial function (Wang et al, 2015;Pereg and McMillan, 2015). In contrast to vegetation, the soil system provides an important carrier for growth of plants and microorganisms.…”
