Light, water and healthy soil are three essential natural resources required for agricultural productivity. Industrialization of agriculture has resulted in intensification cropping practices using enormous amounts chemical pesticides fertilizers that damage these resources. Therefore, there is a need to embrace do not depend on greater use meet the growing demand global food requirements. Plants harbor millions microorganisms, which collectively form microbial community known as microbiome. An effective microbiome can offer benefits its host, including plant growth promotion, nutrient efficiency, control pests phytopathogens. an immediate bring functional potential plant-associated innovation into crop production. In addition that, new scientific methodologies track flux through plant, resident surrounding soil, will opportunities design more efficient consortia design. It now increasingly acknowledged diversity inoculum important promoting ability. Not surprisingly, outcomes from such studies have paradigm shift away single, specific microbes holistic approach enhancing productivity restoration health.

Efforts towards overcoming drought stress in crops: Revisiting the mechanisms employed by plant growth-promoting bacteria

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: July 29, 2022

Globally, agriculture is under a lot of pressure due to rising population and corresponding increases in food demand. However, several variables, including improper mechanization, limited arable land, the presence biotic abiotic pressures, continually impact agricultural productivity. Drought notable destructive stress may be most serious challenge confronting sustainable agriculture, resulting significant crop output deficiency. Numerous morphological physiological changes occur plants as result drought stress. Hence, there need create mitigation techniques since these might permanently harm plant. Current methods used reduce effects include use film farming, super-absorbent hydrogels, nanoparticles, biochar, drought-resistant plant cultivars. activities are money labor-intensive, which offer improvement. The plant-growth-promoting bacteria (PGPB) has proven preferred method that offers indirect direct advantages mitigation. PGPB critical biological elements have favorable impacts on plants’ biochemical features, leading improved sugar production, relative water content, leaf number, ascorbic acid levels, photosynthetic pigment quantities. This present review revisited ameliorating detrimental plants, explored mechanism action employed, well major challenges encountered their application for growth development.

Common bean (Phaseolus vulgaris L.) is the most important legume for human consumption worldwide and an source of vegetable protein, minerals, antioxidants, bioactive compounds. The N2-fixation capacity this crop reduces its demand synthetic N fertilizer application to increase yield quality. Fertilization, yield, quality common may be optimised by several other agronomic practices such as irrigation, rhizobia application, sowing density, etc. Taking into consideration, a systematic review integrated with bibliometric analysis that was conducted, based on literature published during 1971–2021. A total 250 publications were found dealing breeding (n = 61), density season 14), irrigation 36), fertilization 27), intercropping 12), soilless culture 5), tillage 7), biostimulant/biofertilizer 21), disease management 15), pest 2) weed 14). leading research production sites Asia South America, whereas from Australian continent, only four papers identified relevant. keyword co-occurrence network analyses revealed main topics addressed in relation scientific related “pod”, “grain”, “growth”, “cultivar” “genotype”, followed “soil”, “nitrogen”, “inoculation”, “rhizobia”, “environment”, “irrigation”.

Application of microbial inoculants significantly enhances crop productivity: A meta‐analysis of studies from 2010 to 2020

Journal of Sustainable Agriculture and Environment, Journal Year: 2022, Volume and Issue: 1(3), P. 216 - 225

Published: Aug. 27, 2022

Abstract Introduction With the rapid development of microbial technology, inoculant is considered as a promising tool in sustainable agricultural systems. Mechanisms by which inoculants improve crop yield include improving plant nutrient availability and alleviating abiotic/biotic stresses (e.g., drought, salt disease). However, field efficacy remains inconsistent, constrains large‐scale adoptions. Identity dominant mechanisms that underpin positive impacts different limited. Thus, comprehensive quantitative assessment known on performance needed to provide guidance for effective tools from both research commercial perspectives. Materials Methods Based 97 peer‐reviewed publications, we conducted meta‐analysis quantify benefits yield, identify key enhanced yield. Results Result showed (i) alleviation was major mechanism (53.95%, n = 53) enhance while accounted 22.25% ( 58) enhancement. (ii) Pseudomonas most enhancing through (63.91%, 15), whereas Enterobacter (27.12%, 5). (iii) Considering together, (49.94%, 21), (27.55%, 13) Bacillus (25.66%, 32) were largest sources combination diazotroph Burkholderia with its legume host had highest effect (by 196.38%). Microbial also nutritional quality mineral contents produce. Conclusion Our analysis provides evidence can productivity be used either alone or reduced amount agrochemicals promote agriculture.

Agricultural sustainability is of foremost importance for maintaining high food production. Irresponsible resource use not only negatively affects agroecology, but also reduces the economic profitability production system. Among different resources, soil one most vital resources agriculture. Soil fertility key to achieve crop productivity. Maintaining and health requires conscious management effort avoid excessive nutrient loss, sustain organic carbon content, minimize contamination. Though chemical fertilizers have successfully improved production, its integration with manures other bioinoculants helps in improving efficiency, improves some extent ameliorates constraints associated fertilizer application.
