“…The biostimulant produced with humic acids and plant growth-promoting bacteria was used with success on short-cycle plants like maize and tomato [15,16], but for perennial plants under field condition, there are many open questions related to the management and proper use of this biostimulant. The objective of this study was to evaluate the best way and application time of the biostimulant produced with the mixture of plant growthpromoting bacteria and humic acids in sugarcane during the cane plant cycle and two consecutives ratoon crops.…”

Background:The use of biostimulants in agriculture has demonstrated great potential but more consistent field results are required for wider farm acceptance. We evaluated different delivering methods for the biostimulant produced with plant growth-promoting bacteria mixed with humic acid-like substances isolated from vermicompost in the commercial sugarcane crop yield during 3 consecutive years.Results: Foliar spray had a better performance than furrow application and the best result was obtained when the biostimulant was applied at 60 days after emergence, thus enhancing 37% of the stem yield when compared to control. In the first and second ratoons, the productivity increases 5 and 24%, respectively. The first ratoon was marked by severe drought stress that hit all the southeastern of Brazil. Moreover, the assay using strip plot design with a large parcel area confirms the promotion of sugarcane yields by biostimulant during two consecutive ratoons increasing 19 and 18% that represent 11 and 13 tons ha −1 more than the control. The use of biostimulant did not change soluble solid content and polarizable sugars in the sugarcane juice obtained from both experiments. Conclusions:The biostimulant formulated with endophytic diazotrophic bacteria and humic acids represents a lowcost technology that increases the sugarcane yield with economic use of fertilizers to enhance crop yield.

“…These have been applied to promote crop production by different bio-fertilization mechanisms, such as biological nitrogen fixation, production of phytohormones, solubilization of insoluble minerals and biocontrol processes that include phytopathogen antagonism and plant-induced resistance [201][202][203][204]. The presence of bio-protective microorganisms against plant pathogens and plant growth promoting microorganisms confers added value on tomato wasted based compost [205].…”

Abstract:The vast and ever-growing amount of agricultural and food wastes has become a major concern throughout the whole world. Therefore, strategies for their processing and value-added reuse are needed to enable a sustainable utilization of feedstocks and reduce the environmental burden. By-products of potato, tomato, cereals and olive arise in significant amounts in European countries and are consequently of high relevance. Due to their composition with various beneficial ingredients, the waste products can be valorized by different techniques leading to economic and environmental advantages. This paper focuses on the waste generation during industrial processing of potato, tomato, cereals and olives within the European Union and reviews state-of-the-art technologies for their valorization. Furthermore, current applications, future perspectives and challenges are discussed.

“…Concerning plant biofortification, it could be defined as producing different staple foods containing in their edible parts higher content of bioavailable minerals (Fe, Cu, Zn, Ca, Se, I, etc. ), and some nutritional compounds such as folate (Olivares et al 2015;Strobbe and van der Straeten 2017), thiamin or vitamin B1 (Goyer 2017), vitamin B6 (Fudge et al 2017), provitamin A (Halilu et al 2016;Giuliano 2017) and vitamin E (Mène-Saffrané and Pellaud 2017). The plant biofortification mainly is used in micronutrient malnutrition or enriching plants with desirable nutrients or against hidden hunger (El-Ramady et al 2016b;Singh et al 2016;de Valença et al 2017;Díaz-Gómez et al 2017).…”

IT is well known that, sustainable agriculture is an important part of sustainable development. This sustainable agriculture should lead to achieve food security and maintain the biodiversity of natural ecosystems. Sustainable agriculture also should have definitely a global perspective. The conservation of both soil and water resources, therefore, is considered an essential prerequisite as well as the efficient use of mineral and organic fertilizers. This could be achieved by improving agro-technology and better understanding of the essential processes in soils. Foliar application of agrochemicals including fertilizers should be improved seeking for the sustainability of agriculture. The present review will focus on the effects of foliar application of nutrients for plant nutrition and its biofortification. Proper timing of foliar application, endo-, exogenous and environmental factors affecting foliar nutrition, influence of mineral fertilizer nutritional quality of staple food crops and finally nano-foliar nutrition as well as postharvest quality of crops will be also highlighted.
