Abstract

REYES-PEREZ, Juan José et al. Chitosan application increases the emergence, growth and yield of tomato crop (Solanum lycopersicum L.) under greenhouse conditions. Biotecnia [online]. 2020, vol.22, n.3, pp.156-163.  Epub Feb 10, 2021. ISSN 1665-1456.  https://doi.org/10.18633/biotecnia.v22i3.1338.

Current agriculture looks for products that allow the growth and development of crops, as well as increase yields, and also that the active principles are of natural origin, biodegradable and do not cause damage to the environment. The purpose of this research was to evaluate the effect of the application of chitosan at doses of 1, 2 and 3 g L-1 in the emergence, development and performance of the Floradade and Amalia tomato varieties, under greenhouse conditions. The experimental design was a randomized complete block, with a 2 x 3 + 2 factorial arrangement. The results showed that the 2 g L-1 dose was the one with the highest values in the emergence and development of tomato plants, stimulating higher fruiting, fruit weight and higher yield in the Floradade variety. It is concluded that the application of chitosan at doses of 2 g L-1 under our experimental conditions, increased the yields of the tomato crop in the Floradade variety.
