Abstract

The demand for fig (Ficus carica L.) is growing worldwide, leading to the search for higher crop yield. One of the most promising strategies is the application of plant growth promoter microorganisms (PGPM), which are used as inoculants in plants. Amendments are also used to improve soil conditions, one of the most widely used in agricultural gypsum. The objective of this study was to evaluate the combined application of PGPM (Bacillus subtilis, Bacillus cereus, Pseudomonas fluorescens, and Trichoderma harzianum) with agricultural gypsum (AG) in the soil, through microbiological, nutritional, and physiological analysis in fig plants. The inoculation of PGPM (108 CFU m-2) with AG (calcium 40 kg ha-1) was performed in three treatments: T1: Control, T2: Bacterial consortium, and T. harzianum with AG and T3: T. harzianum with AG under a randomized complete blocks experimental design. The inoculation with T2 and T3 helped improve the photosynthesis variables, fruit number, fruit weight (30.5 %), and yield (T2 38.35 % and T3 41.98 %). Furthermore, the inoculation with T3 helped the resistance to penetration (T3 7.2 lbF-T1 4.6 lbF) and the increase in Brix degrees (T3 22.5-T1 21.9) in the fruits.
