Trichoderma harzianum as a growth promoting agent in hydroponic culture of tomato (Solanum lycopersicum)

Abstract

Tomato, due to its nutritional characteristics, is considered as a food of great commercial interest throughout the world. The importance of the crop has generated several studies that seek to increase its production through the application of biofertilizers based on beneficial microorganisms. Hydroponic cultivation is a method that allows plant production without the need to use the soil as a source of nutrients, or as a physical support. Some advantages of hydroponic systems are: there is no competition for nutrients, the roots develop in better growing conditions, minimal loss of water, no issues with weeds, reduction in the application of agrochemicals and the system adjusts to non-traditional production areas. With this technique it is possible to obtain vegetables of excellent quality and health. The objective of this work was to evaluate the growth promoting capacity of Trichoderma harzianum ITEM 3636 in hydroponic tomato cultures.
