ORGANIC-BIOLOGICAL AND CONVENTIONAL TOMATO GROWEN (Lycopersicon lycopersicum Mill) IN A GREENHOUSE
Abstract
The aim of this research was to determine the possibility of tomato production in the organic-biological conditions and to compare it with the conventional tomato production. The research lasted for three years. Each type of organic manure and organic substrates used as the preparation of the organic-biological production underwent many agrochemical and microbiological analyses. There were no significant plant diseases or pests during the entire course of organic-biological tomato production. Duration of organic-biological production from the day of planting till picking time was shorter than for the conventional production. Moreover, the Monroe hybrid had heavier mean fruit weight, whereas both hybrids had approximately the same mean fruit number per plant. Regular monitoring and control of all technological parameters which are the most influential in greenhouse conditions for organic-biological tomato production provided satisfying qualitative and quantitative tomato yield for further market demands. Statistical data analysis was conducted through three way covariance analysis (ABC) with three repetitions for each trial. The trial revealed statistically justified difference for the studied hybrid types (P<0,05) throughout the three years' period (P<0,01). The differences between the crop production were not statistically significant (P<0,05), whereas interaction of hybrids and crop production was statistically very significant (P<0,01). Interaction of the studied factors has not been statistically justified (P<0,05).
