ZULUETA-RODRIGUEZ, R. et al. Effects of co-inoculation of Bacillus subtilis and Rhizoglomus intraradices in tomato production (Solanum lycopersicum L.) in a semi-hydroponic system.

The use of rhizobacteria and arbuscular mycorrhizal fungi is a promising technique to implement in semi-hydroponic systems. In this study, the application of Bacillus subtilis (Bs) and Rhizoglomus intraradices (Ri) were used to assess its effect on the growth, production and quality of two hybrids of tomato (‘Caporal’ and ‘SV8579TE’) in a semi-hydroponic growing system. An experimental randomized block design with 25 replications and four treatments (T) for each hybrid was used: T1: (Control, T), T2: (Bs), T3: (Ri) and T4: (Bs+Ri). The parameters evaluated were: seedling height, stem diameter, number of bunches, number of fruits, green index, fruit quality and total production. The data were processed using analysis of variance and Fisher’s Protected LSD test, with a significance level of 5 %. The results showed that simple inoculation of Bs and Ri stimulated growth and fruiting indicators in both hybrids, but a superior response was found in the presence of co-inoculation, with significant increases in total production. The use of B. subtilis and R. intraradices can improve the production of tomato in a semi-hydroponic system.
