“…Similar results regarding www.nature.com/scientificreports www.nature.com/scientificreports/ PGPM application was also reported by Adesemoye et al 11 that the growth and yield of tomato grown in a greenhouse with 75% fertilizer plus PGPM were statistically equivalent to those obtained using full fertilizer rates without PGPM. Moreover, some reports showed that bio-organic fertilizers could replace 23-52% of N fertilizer without any loss of yield 24 , which also indicating the potential role of bio-organic fertilizer in reducing the amount of chemical fertilizer load to soil. Whereas, few previously reported evidences regarding the influence of PGPM or its bio-fertilizer application on crop quality could be found 8,11 .…”

the extensive use of chemical fertilizers poses serious collateral problems such as environmental pollution, pest resistance development and food safety decline. Researches focused on applying plant-beneficial microorganisms to partially replace chemical fertilizer use is increasing due to the requirement of sustainable agriculture development. Thus to investigate the possibility of a plantbeneficial Trichoderma strain and its bio-organic fertilizer product in saving chemical fertilizer application and in improving crop quality, a field trial and continuous pot experiments were carried out with tomato. Four treatments were set up: a reduced application of chemical fertilizer (75% of the conventional application) plus Trichoderma-enriched bio-organic fertilizer (BF), organic fertilizer (OF) or Trichoderma spore suspension (SS), with using the 100% rate of the conventional chemical fertilizer as the control (CF). The results showed that the total soluble sugar, Vitamin C and nitrate accumulations were, respectively, +up to 24%, +up to 57% and-up to 62% in the tomatoes of the BF treatment compared to those of the control (CF). And both of the pot and field trials revealed that reduced rates of chemical fertilizer plus bio-organic fertilizer produced tomato yields equivalent to those obtained using the 100% of the chemical fertilizer. However, application with the inoculant alone (SS) or combined with the organic fertilizer alone (OF) would lead to a yield decreases of 6-38% and 9-35% over the control. Since the increased abundance of soil microflora and the enhanced soil fertility frequently showed positive linear correlations especially in the BF-treated soils, we conclude that the efficacy of this bioorganic fertilizer for maintaining a stable tomato yield and improving tomato quality may be due to the improved soil microbial activity. Thus, the results suggest that the Trichoderma bio-organic fertilizer could be employed in combination with the appropriate rates of chemical fertilizers to get maximum benefits regarding yield, quality and fertilizer savings.

“…Seeking a new type of fertilizer could be one solution. Rose et al (2014) reported that the biofertilizer containing plant growth promoting microorganisms could replace between 23 and 52 % of nitrogen (N) fertilizer without loss of yield. Ali et al (2014) also reported that Anabaena azollae in combination with urea and silicate fertilization decreased the total seasonal CH 4 flux by 12 % and increased rice grain yield by 10.6 %.…”

Direct-seeded rice is a promising option because it saves water and labor, and it increases productivity. Nonetheless, few studies have evaluated the transition from traditionally transplanted rice to direct-seeded rice. Here we compared yield, water productivity, and greenhouse gas emissions of dry direct-seeded rice, wet direct-seeded rice, and transplanted rice in Central China in 2014 and 2015. We grew four rice cultivars: Huanghuazhan, LvdaoQ7, Yangliangyou6, and Yliangyou1. We measured grain yield, yield components, water consumption, water productivity, and greenhouse gas emissions. Our results show that the grain yield of wet direct-seeded rice was 10.8 % higher than that of transplanted rice, when averaged across cultivars and both years. Grain yield of dry direct-seeded rice and transplanted rice was similar. Water productivity of dry direct-seeded rice was 11.6 % higher than that of transplanted rice. Water productivity of wet direct-seeded rice was 13.4 % higher than that of transplanted rice. Global warming potential was 76.2 % lower for dry direct-seeded rice and 60.4 % lower for wet direct-seeded rice than for transplanted rice. Wet direct-seeded rice was found to be more susceptible to lodging than dry direct-seeded rice and transplanted rice. Overall, wet direct-seeded rice is the best system for Central China due to higher grain yield and water productivity and lower global warming potential. Dry directseeded rice may also be suitable for some regions where water is scarce for soil puddling during land preparation.

Resumen L a utilización de bioinoculantes e insumos naturales es una alternativa viable en la producción de cultivos. El propósito del estudio consistió en comparar el 100 % de fertilización convencional (100N-40P-00K, testigo) con el efecto de gallinaza, la inoculación del hongo micorrícico arbuscular (HMA) Rhizophagus intraradices (micorriza INIFAP) y 50 % de fertilización química, independientes o en combinación sobre variables de planta, macollo y rendimiento de repollo (Brassica oleracea var capitata, cv. 'Copenhagen Market'). En semillero se comparó la emergencia de plántulas crecidas en sustrato con y sin HMA. En campo se evaluó clorofila, diámetro de planta, diámetro y peso de macollo y rendimiento. Además, el beneficio-costo (b/c) fue estimado para cada tratamiento. La inoculación micorrícica incrementó significativamente en 19 % la emergencia de plántulas en comparación con las no inoculadas. El crecimiento y rendimiento mostraron diferencias no significativas entre los tratamientos. Los resultados indicaron la factibilidad de restringir 50 % o sustituir la fertilización sintética convencional mediante el uso de gallinaza y micorriza arbuscular en la producción de repollo. El tratamiento más rentable (b/c= 4.7) fue el de inoculación micorrícica en almácigo y la adición del 50 % de la fertilización química (50N-20P-00K). AbstractT he use of microbial inoculants and natural resources is a viable alternative in crop production. The purpose of the present study was to compare 100 % of conventional synthetic fertilization (100N-40P-00K, control) with the effect of chicken manure, inoculation with arbuscular mycorrhizal fungi (AMF) Rhizophagus intraradices (mycorrhiza INIFAP) and 50 % of chemical fertilization alone or in combination on plant attributes, cabbage (Brassica oleracea var capitata, cv. Copenhagen Market) heads and yield. In nursery, comparison of seedlings emergence was performed taking into account both types of seeds inoculated or not with AMF. In field, comparison of chlorophyll index, diameter of plant, diameter and weight of cabbage heads and yield were performed taking into account the different treatments. In addition, the benefit-cost of production was estimated for each treatment. Inoculation with AMF increased significantly by 19 % the emergence of seedlings in comparison with seedlings without AMF. Plant growth and yield showed no significant differences among treatments. Results showed the feasibility of restricting 50 % or replacing conventional synthetic fertilization by chicken manure and arbuscular mycorrhizal fungi in the production of cabbage. The best benefit-cost (b/c=4.7) corresponds to the inoculation with mycorrhizal fungi in seedbed and the addition of 50 % of chemical fertilizer (50N-20P-00K).
