    Abstract: The increasing demand of food causes an excessive exploitation of agricultural lands, often inducing phenomena of soil sickness accompanied by the development of soilborne diseases. The use of residual biomasses together with inorganic fertilizers can be considered a good agricultural practice for controlling the inoculum density of soilborne phytopathogens since soil conditioners can release inorganic nitrogen, polyphenols and fatty acids that, especially in vitro, have demonstrated various degree of suppressiveness against such pathogens. Further, soil organic amendments can also modify the population of soil culturable bacteria and fungi that, in turn, can affect the soilborne diseases in several ways. With this study, the authors aim to evaluate the impact of the synergistic application of different biomasses and inorganic fertilizers on the soil inoculum density of Verticillium dahliae and Phytophthora spp . during two potato cycles under open-field conditions. The biomasses used for the fertilization of the potato crop were olive pomace residues (OPR), composts from municipal solid wastes (CMW), spent mushroom compost (SMC), and livestock manure-based compost (BRX). Results The inoculum density of Verticillium dahliae appeared inhibited by BRX due to its low C/N ratio that caused a quicker release of inorganic nitrogen with respect to the others soil conditioners. In contrast, OPR was conducive to the aforementioned soilborne pathogen since that biomass was characterized by a very high percentage of unsaturated fatty acids that, rather, stimulate the inoculum density of V. dahliae . Finally, polyphenols did not influence the same pathogen because they apparently turned into no toxic compounds very quickly. The inoculum density of Phytophthora spp . was reduced equally by all the biomasses used in combination with the inorganic fertilizers, regardless of their composition and quantity, mainly because of the development of general microbial suppression. Therefore, the chemical characteristics of the soil conditioners apparently did not affect the inoculum density of Phytophthora spp. Conclusions The results of this work underline the behavioral diversity of the different pathogens towards the different means adopted. Phytophthora spp. are sensitive to any kind of biomasses combined with inorganic fertilizers while the inoculum density of Verticillium dahliae should be reduced using soil conditioners characterized by low C/N ratio and low quantity of unsaturated fatty acids.

    Abstract: The increasing food demand encourages the overuse of agricultural lands and natural resources that often is not economic, social, and environmentally sustainable. This overuse can lead to the soil sickness, which causes the decline of the soil fertility through the development of soil‐borne diseases, the depletion of nutrients, and the loss of soil organic matter. Addition of residual biomasses is a good agricultural practice for improving soil properties and enhancing crop production, in the framework of a sustainable development. The study is performed in a 2 years field experiment using olive pomace residues (OPR), composts from municipal solid wastes (CMW), spent mushroom compost (SMC), and livestock manures based compost (BRX) for the fertilization of the potato crop. The aim of the study is to test the impact of different biomasses available in Apulia region, Italy, on soil fertility and potato growth. The application of BRX shows the highest potato yield in both seasons while OPR, CMW, and SMC significantly increases soil total nitrogen and organic carbon compared to BRX and un‐amended plots (CON). All treatments, except SMC, reduce the soil exchangeable K content, therefore, the application of BRX, OPR, and CMW should include the use of K based fertilizer to balance the high crop demand of K. Finally, SMC appears the best compromise for managing soil fertility and obtaining high potato yield.

    Abstract: In order to assess the effects of green synthesized nanoparticles (GNPs) of Zn and Fe oxides on plant growth traits, photosynthetic capacity and nutritional quality of red radish (cv. Champion), two open field experiments were organised based on RCBD with four replicates. Treatments included: chicken manure, foliar application of ZnO + FeO (GNPs at a rate of 60 and 50 ppm, respectively), chicken manure plus ZnO + FeO (GNPs). This study revealed that growth and yield of radish plants significantly increased by ZnO + FeO nanoparticles application. The maximum vegetative growth, leaf pigments and root quality (diameter and weight) were recorded in plants treated with ZnO + FeO (GNPs) alone or in combination with chicken manure. Furthermore, the combined application of chicken manure with ZnO and FeO significantly improved the concentration of anthocyanins, phenols, tannins, flavonoids, crude protein and carbohydrates contents in radish root than single treatment. Similar trends were noted in photosynthesis rate, water use efficiency and values of Zn and Fe contents. In addition, health risk index for Zn and Fe were less than 1, which indicated to red radish plants supplied with ZnO and FeO GNPs were free of risks on human health. It was concluded that combination between chicken manure and ZnO + FeO GNPs can be considered as appropriate strategy for improving yield and nutritional status of red radish.
