Effects of production method and substrate on yield and quality of lettuce (Lactuca sativa L.)
2004
Balalic, I.
A study has been conducted in order to investigate the effects of different production methods (without mulching, mulching with black PE, mulching with black PE and canvas), locations of production (plastic house, open field) and substrates on the head weight and quality traits in the lettuce variety 'Histor'. Seedlings were grown on a domestic substrate and Klasmann Deilman substrate. The experimental design was split-plot with three replications. The experiment was carried out during two growing seasons (2002 and 2003). Head weight and quality traits were analyzed. The nutritive value of lettuce was also evaluated. The production method, location of production and location/production method interaction had significant effects on head weight. The mean value for head weight was highest when lettuce was grown from seedlings on the Klasmann substrate, mulched with black PE and canvas. The quality traits (dry matter content, concentrations of N, P, K, Ca, Mg, Fe, Zn, C vitamin and nitrates) depended on substrate, production method, location of production and the interaction location/production method. Based on the results of this thesis, it is recommended to grow lettuce from seedlings produced on Klasmann substrate in the open field and mulched with black PE.
