Abstract

The crop protection with colorful knits and Nonwoven Textile has been much used, for improvement of the efficiency of cultivation and minimizing pesticide application. Thus, this study aimed to verify the effect of the type of protection of plants or fruits of two tomato hybrids, conducted in a protected environment, with and without application of insecticides in the experimental area of UNESP - Campus of Ilha Solteira. The following parameters were evaluated: height; average diameter of the stem; average rates of absolute growth and productivity of total commercial and bored fruits. The experimental design was a Randomized Block Design (RBD), with treatments arranged in a split plot in a 4x2x2 factorial scheme, with four types of protection, two types of application of insecticides and two hybrids. The results were subjected to analysis of variance (F test) and the effects of treatments were compared by Tukey test at 5% probability, leading to the following conclusions: the application of insecticides did not affect the growth of plants; the greenhouse protected with Blue Chromatinet 30% gave higher plant height; hybrid Saladete had better adaptation to growing conditions; greenhouses having no side protection showed greater total productivity, however with higher losses due to the disposal of unmarketable fruits; the greenhouse protected by Nonwowen Textile gave the lowest productivity of bored fruit in the treatments with and without application of insecticides; the hybrid Saladete proved to be better adapted to growing conditions showing greater business productivity and lower yields of bored fruit.
