“…The highest values of FWP and NAE as resulted in LD + BC administration indicated a maximized use of water and nitrogen, in both the trial years. These findings agreed with previous investigations, indicating the positive correlation between marketable yield and water and nutrient use efficiencies in processing tomato production [49,63].…”

“…Barrios-Masias et al [49] reported a positive correlation between tomato yield and leaf photosynthetic activity and the same physiological behavior was also reported for other crops like wheat [55]. NBI, calculated as the ratio between chlorophyll and polyphenols leaf contents, is an index of the crop nitrogen status [56].…”

“…The highest marketable yield displayed by LD + BC fertilization can be related to seven main parameters: fruit number per plant, fruit weight, plant height, main stem length, aboveground biomass production, FWP and NAE, according to the results showed by Barrios-Masias and Jackson [49] and, Ronga et al [48], which investigated the main morphological and physiological parameter involved in increasing marketable yield under different environments (California and Italy, respectively).…”

The principal goal of the organic farming system (OFS) is to develop enterprises that are sustainable and harmonious with the environment. Unfortunately, the OFS yields fewer products per land than the non-organic farming system in many agricultural products. The objective of our study was to assess the effects of digestate and biochar fertilizers on yield and fruit quality of processing tomato produced under the OFS. The experiment was carried out in Po Valley, during the 2017 and 2018 growing seasons. Liquid digestate (LD), LD + biochar (LD + BC) and pelleted digestate (PD) were evaluated and compared to biochar (BC) application and unfertilized control. The results showed that plants fertilized with LD + BC recorded the maximum marketable yield (72 t ha−1), followed by BC (67 t ha−1), PD (64 t ha−1) and LD (59 t ha−1); while the lowest production (47 t ha−1) was recorded in unfertilized plants. Over the two cropping seasons, LD + BC, BC, PD, and LD, increased fruit number per plant (+15%), fruit weight (+24%), Brix t ha−1 (+41%) and reduced Bostwick index (−16%), if compared to the untreated control. Considering the overall agronomic performances, digestate and biochar can be useful options for increasing yield and quality of processing tomato production in the OFS. Hence, these fertilizers can be assessed in future research both on other crops and farming systems.

“…Our findings highlighted that the breeding program for processing tomato (the introgression of favorable traits to the harvesting machinery associated with reduced plant height, average fruit weight, and increased marketable yields) [42] did not select against AM fungal symbiosis in processing tomato. These results corroborated those previously reported by De Vita et al [43] for durum wheat.…”

Climate change is increasing drought events and decreasing water availability. Tomato is commonly transplanted to an open field after seedling production in a nursery, requiring large volumes of water. Arbuscular mycorrhizal (AM) fungi help plants cope with drought stress; however, their effects depend on plant genotype and environmental conditions. In this study, we assessed the interactions among different tomato seedling genotypes and two AM fungi, Funneliformis mosseae and Rhizophagus intraradices, under two water regimes, full and reduced. Our results showed that F. mosseae was more effective than R. intraradices in the mitigation of drought stress both in old and modern genotypes. However, seedlings inoculated with R. intraradices recorded the highest values of leaf area. ‘Pearson’ and ‘Everton’ genotypes inoculated with F. mosseae recorded the highest values of root, leaf, and total dry weights under reduced and full irrigation regimes, respectively. In addition, ‘Pearson’ and ‘H3402’ genotypes inoculated with F. mosseae under a reduced irrigation regime displayed high values of water use efficiency. Our results highlight the importance of using AM fungi to mitigate drought stress in nursery production of tomato seedlings. However, the development of ad hoc AM fungal formulations, which consider genotype x AM fungi interactions, is fundamental for achieving the best agronomic performances.

BACKGROUND The total amount of bio‐waste produced annually in the EU by the food and beverage chains is estimated at 37 billion kg. The use of insects for the valorization of by‐products from these value chains may represent a sustainable solution. This study aimed to investigate the by‐products obtained from different food chains and used for the rearing of black soldier fly (BSF) prepupae, and to evaluate the content and profile of the lipid extracted from the prepupae and outline its possible applications. The substrates used in this experiment were: (i) industrial by‐products (brewery spent grains, cows’ milk whey, grape stalks, and tomato peels and seeds) and (ii) by‐products from retailers (bread dough, fish scraps, and spent coffee ground). Fat extracted from prepupae using an adjusted Folch method was used for total lipid content and fatty acid profile. RESULTS The best larval performances were obtained from beer (0.22 gweight per prepupa), tomato (0.19 gweight per prepupa), and cheese (0.14 gweight per prepupa) food‐chain by‐products. The extremely different compositions of the substrates were reflected in the differentiated lipid profile of the BSF prepupae and in the range of ratios between unsaturated and saturated fatty acids, which varied from 0.37 for cows’ milk whey to 1.34 for tomato peels and seeds. CONCLUSION The lipids, proteins, and chitin extracted from prepupae are high‐value bio‐based products that could be used in the feed / food industry or for the development of innovative biomaterials, such as biodiesel. These results suggest that food‐chain by‐products are the best candidates for insect‐bioconversion purposes. © 2020 Society of Chemical Industry
