REYES-PEREZ, Juan José et al. Use of humates of vermicompost to reduce the effect of salinity on growth and development of basil (Ocimum basilicum L.). Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.6, pp.1375-1387. ISSN 2007-0934.

Plant growth bio-stimulants are natural substances to treat crops as activators of physiological functions, so its application allows a better use of nutrients and represent an appropriate option to address problems of abiotic stress by salinity. The aim of this study was to determine the effect of humates of vermicompost as attenuating of salinity in growth and development of two varieties of basil (Ocimum basilicum L.), one tolerant and one sensitive to salinity, which underwent three NaCl concentrations (0, 50 and 100 mM) and the application of humates of vermicompost with two dilutions (0 and 1/60 v/v) in a completely randomized design with six replications. The work was developed in a greenhouse and stem and root length, fresh and dry biomass of root, stem, leaf and leaf area were measured. The results showed that Napoletano variety in 0 mM NaCl and the dissolution of 1/60 (v/v) humates of vermicompost was the best response in all variables measured, while lower values were for Sweet Genovese in 100 mM NaCl. The differential response between varieties when subjected to different levels of NaCl and application of humates of vermicompost is discussed.
