“…The higher TSS recorded in 'Ventana' grown organically could be due to lower fruit water content (i.e. greater dry matter percentage), as observed in previous studies [34,36]. Furthermore, the higher availability of N in the conventional farming may also explain the lower TSS in berries, as in Cantliffe et al [43], and shows that increasing amounts of N will decrease strawberry fruit TSS.…”

-Introduction. Consumer interest in organic fruit is increasing based on the assumption that these products are healthier, despite a lack of conclusive evidence. Strawberry (Fragaria × ananassa Duch.) is a rich source of antioxidants and an important fruit in the human diet. Materials and methods. The configuration of strawberry fruit quality was analyzed in a factorial approach accounting for the effects of the farming system and postharvest frozen storage. The strawberry cultivars 'Sabrina' and 'Ventana' grown under organic and conventional farming management were stored postharvest at −40• C for 6 months. Fruits obtained under the two farming systems were analyzed fresh after harvest and thawed after frozen storage. Fruit quality was evaluated in terms of physical, chemical and phytochemical properties. Results and discussion. The surface lightness, firmness, lipophilic antioxidant activity, soluble solids, ascorbic acid and ellagic acid contents were significantly higher at harvest than after thawing. Frozen storage increased only hydrophilic antioxidant activity, leaving reducing sugars and total phenols without significant alterations. The color of organic fruits in both cultivars was brighter and more vivid (higher L* and C* values). Farming management did not affect the reducing sugars and ascorbic acid contents for the 'Sabrina' (4.6% and 55.5 mg 100 g −1 FW, respectively) or 'Ventana' (4.0% and 31.2 mg 100 g −1 FW, respectively) cultivars. The organic 'Ventana' strawberry had higher soluble solid content and hydrophilic antioxidant activity, whereas an opposite trend was observed in total phenols and ellagic acid contents for 'Ventana' and 'Sabrina', respectively. Conclusion. The quality of strawberries, in particular the bioactive compounds, varied according to the farming system and postharvest frozen storage. The cultivation factors, including the farming management and cultivar, may significantly interact to affect quality attributes of strawberry fruit.Keywords: Italy / strawberry / Fragaria × ananassa / organic farming / fruit quality / antioxdant activity / ascorbic acid / ellagic acid / phenolics Résumé -Effet du système de culture et de congélation post-récolte sur les attributs de qualité de deux cultivars de fraisier.

“…High moisture in soils facilitated the release of compounds accumulated by soil microbes and motivated microbial activity and growth [30]. High EC may result in nitrogen depletion, nutrient reduction, and decrease in strawberry yield [31–32]. The pH level and EC both declined after treatment for six years.…”

“…On the sixth year, strawberry yields increased by 555.91 kg/ha compared with that without applying soil conditioner (Table 3). This phenomenon was greatly associated with pH changes, because the optimum pH for strawberry growth is 5.5–6.5 [31]. Plant productivity is more sensitive to soil pH and nutrient [53], because it directly influences the uptake of mineral nutrients by the soil microorganism.…”

Rapid fermentation of food waste can be used to prepare soil conditioner. This process consumes less time and is more cost-effective than traditional preparation technology. However, the succession of the soil microbial community structure after long-term application of rapid fermentation-derived soil conditioners remains unclear. Herein, dynamic rapid fermentation (DRF) of food waste was performed to develop a soil conditioner and the successions and diversity of bacterial communities in an organic-matter-impoverished arable soil after six years of application of DRF-derived soil conditioner were investigated. Results showed that the treatment increased soil organic matter (SOM) accumulation and strawberry yield by 5.3 g/kg and 555.91 kg/ha, respectively. Proteobacteria, Actinobacteria, Acidobacteria, and Firmicutes became the dominant phyla, occupying 65.95%–77.52% of the bacterial sequences. Principal component analysis (PCA) results showed that the soil bacterial communities were largely influenced by the treatment. Redundancy analysis (RDA) results showed that the relative abundances of Gemmatimonadetes, Chloroflexi, Verrucomicrobia, Nitrospirae, and Firmicutes were significantly correlated with soil TC, TN, TP, NH4+-N, NO3−-N, OM, and moisture. These communities were all distributed in the soil samples collected in the sixth year of application. Long-term treatment did not enhance the diversity of bacterial species but significantly altered the distribution of major functional bacterial communities in the soils. Application of DRF-derived soil conditioner could improve the soil quality and optimize the microbial community, ultimately enhancing fruit yields.

“…Although studies have shown that all mineral fertilizers (N, P, and K) and water have effects on the yield and quality of strawberries, most of them only focused on either the effect of water [26–28] or the effect of fertilization [29–33]. The combined application of N, P, and K (NPK) fertilizers and water for high yield and good fruit quality is rarely reported [27,31,34]. Thus, the interaction effect among N, P, and K fertilizers and water on the strawberry yield and fruit quality should be investigated.…”

2 21 Abstract 22 Nitrogen (N), phosphorus (P), potassium (K), and water are four crucial factors that have significant effects on strawberry yield 23 and fruit quality. A quadratic regression orthogonal rotation combination experiment that involved 36 treatments with five 24 levels of the four variables (N, P, and K fertilizers and water) was executed to optimize the fertilization and water combination 25 for high yield and quality. SSC/TA ratio (the ratio of soluble solid content to titratable acid) was selected as the index of 26 quality. Results showed that the N fertilizer was the most important factor, followed by water and P fertilizer, and the N 27 fertilizer had a significant effect on yield and SSC/TA ratio. By contrast, the K fertilizer had a significant effect only on yield. 28N×K fertilizer interaction had a significant effect on yield, whereas the other interactions among the four factors had no 29 significant effects on yield and SSC/TA ratio. The effects of the four factors on the yield and SSC/TA ratio were ranked as N 30 fertilizer > water > K fertilizer > P fertilizer and N fertilizer > P fertilizer > water > K fertilizer, respectively. The yield and 31 SSC/TA ratio increased and then decreased when NPK fertilizer and water increased. The optimal fertilizer and water 32 combination was 22.28-24.61 g/plant Ca (NO 3 ) 2 ·4H 2 O, 1.75-2.03 g/plant NaH 2 PO 4 , 12.41-13.91 g/plant K 2 SO 4 , and 12.00-33 13.05 L/plant water for yields of more than 110 g/plant and optimal SSC/TA ratio of 8.5-14. Introduction 35Mineral fertilizers and water have a significant effect on crop yield [1-3]. However, the excessive application of fertilizers may 36 lead to soil and water pollution and become a serious threat to food safety [4,5]. Meanwhile, water scarcity is now a major 37 challenge in China [6]. Therefore, a good management of fertilization and water is increasingly required for agriculture in China. 38Strawberry is one of the most profitable fruit cultivars in China, which ranks first in total strawberry production worldwide 39 with a production of 1,801,865 tons in 2016, followed by United States and Mexico among a total of 79 countries [7]. Thus, large 40 amounts of fertilizers and water are needed for strawberry production in China. Consumers prefer strawberries with a sweet taste 41 [8,9]. The strawberry flavor is strongly correlated with the balance between the soluble solid content (SSC) and titratable acid 42 (TA) in ripe fruits [10,11], which are common quality indexes to assess sweetness and sourness [12]. The ratio of SSC/TA is 43 another effective parameter to determine fruit flavor [13,14]. The higher the SSC/TA ratio, the sweeter the fruit [15]. Therefore, 44 increasing strawberry production and enhancing fruit quality with high SSC/TA ratio and without environment pollution are 45 important goals in the field. 46Nitrogen (N), phosphorus (P), and potassium (K) are primary mineral fertilizers. N is the most limiting nutrient to crop nutrient is essential for photosynthesis [20], and it is requ...
