Growth mean an increase in dry mass or dry mass of plant as a measure of its growth. The relationship between dry mass gains and time used as basic parameters in growth analysis concept. Relative growth, the increase in weight per unit of original weight over a time interval. Leaf area ratio, ratio of leaf area to plant dry weight. Net assimilation rate, the rate of increase in dry weight per unit leaf area. Temperature and light affected the dynamic of growth. The experiment was conducted using hydroponic system to growth analysis of lettuce in dry and rainy planting seasons. More chlorophyll content and magnesium up taken were found in rainy than dry season. Light intensity influence growth analysis. More grade of relative growth rate, leaf area ratio and net assimilation rate were found in rainy than dry season. Dry mass productivity of lettuce leaf in rainy more effective and efficient than dry season.
Key words: growth, lettuce, seasons
