Abstract
Although resistance to both biotic and abiotic factors has been included as a selection criterion in plant breeding programs for years, environmentally friendly microbial products may offer a viable alternative as they are able to contribute to crop resistance to the undesirable effects of climate change.
In the present study, we have analyzed the performance of Solanum lycopersicum L., an important crop of great agronomic interest and widespread worldwide, under water stress by supplying different microbial products to the crop.
The project was carried out using bacteria from the Biomar collection with the development of work at CTAEX. In this sense, the aim was to assess the effect of 8 different bacterial strains on plant size, development parameters and productivity in processing tomato under different water regimes.
For this purpose, a field trial was conducted, evaluating whether the plants showed the beneficial properties transmitted.
In this research, the following parameters were evaluated: the health status of the plant, plant cover on the soil (%), chlorophyll (SPAD), nutritional status through foliar analysis, crop yield and brix degrees under 3 different water conditions: Control irrigation (100%) with 5,500 m3 ha-1 Crop evapotranspiration (ETC needs), 75% (25% reduction compared to the control) and 50% (50% reduction compared to the control). Within the yield parameters, tomatoes were evaluated according to their size (<40 mm, 40-60 mm, >60 mm), maturity stage (overripe, ripe, and green) and health status.
After analyzing the results, we have been able to verify the effect of different bacterial treatments on parameters such as net yield (kg ha-1), giving higher values in all the water regimes compared to the control treatment, which translates into a greater benefit for the producer, with higher yields on the one hand and lower water consumption on the other.
