Nowadays one of the main challenges in agriculture is to increase crop yield and quality in a sustainable way. Organic farming system (OFS) is considered more eco-friendly than the conventional farming system (CFS). However, cash crops showed a reduced yield when cultivated in OFS, and among them processing tomato reported the highest yield gap between OFS and CFS. Therefore, the objective of this study was to investigate, both in greenhouse and field experiments, the combined effects of a cherry rootstock, genotype ‘Tomito’, and the applications of different microbial biostimulants (single species and consortia). The agronomic performance of a commercial processing tomato genotype, ‘H3402’, was assessed in order to increase fruit yield and quality in sustainable farming systems. In greenhouse experiment, the use of ‘Tomito’ as rootstock highlighted both the highest plant height (35 cm) and leaf chlorophyll content (25.20), while plants inoculated with A. brasiliensis showed the highest number of flowers (4.5). In field experiment, the combined use of grafting and microbial biostimulants increased marketable (on average 2.3 kg plant–1) and total yields (on average 2.5 kg plant–1) in comparison with the genotype ‘H3402’. All the investigated treatments reduced the number of fruits affected by blossom-end rot (on average –4.7 fruits plant–1), and A. brasiliensis also improved the fruit solid soluble content, recording values of 6.23 °Brix and 3.54 of Brix t ha–1.

生物刺激素和樱桃砧木提高了可持续农业系统中番茄果实的产量和质量

如今，农业面临的主要挑战之一是以可持续的方式提高作物产量和质量。有机耕作系统 (OFS) 被认为比传统耕作系统 (CFS) 更环保。然而，经济作物在 OFS 中种植时产量下降，其中加工番茄报告 OFS 和 CFS 之间的产量差距最大。因此，本研究的目的是在温室和田间试验中研究樱桃砧木、基因型“Tomito”以及不同微生物生物刺激素（单一物种和联合体）的应用的综合影响。评估了商业加工番茄基因型“H3402”的农艺性能，以提高可持续农业系统中的果实产量和质量。在温室实验中，使用'Tomito' 作为砧木突出了最高的植物高度（35 厘米）和叶叶绿素含量（25.20），而接种巴西木虱的植物表现出最高的花数（4.5）。在田间试验中，与基因型“H3402”相比，嫁接和微生物生物刺激素的结合使用增加了适销性（平均 2.3 kg 植物-1）和总产量（平均 2.5 kg 植物-1）。所有调查的处理都减少了受花期腐烂影响的果实数量（平均为 –4.7 个果实植物 –1），A. brasiliensis 还提高了果实固溶物含量，记录值分别为 6.23 °Brix 和 3.54 Brix t ha –1. 与基因型“H3402”相比，嫁接和微生物生物刺激素的结合使用增加了适销性（平均 2.3 kg 植物-1）和总产量（平均 2.5 kg 植物-1）。所有研究的处理都减少了受花期腐烂影响的果实数量（平均为 –4.7 个果实植物 –1），A. brasiliensis 还提高了果实固溶物含量，记录值为 6.23 °Brix 和 3.54 Brix t ha –1. 与基因型“H3402”相比，嫁接和微生物生物刺激素的结合使用增加了适销性（平均 2.3 kg 植物-1）和总产量（平均 2.5 kg 植物-1）。所有研究的处理都减少了受花期腐烂影响的果实数量（平均为 –4.7 个果实植物 –1），A. brasiliensis 还提高了果实固溶物含量，记录值为 6.23 °Brix 和 3.54 Brix t ha –1.
