Growth behaviour, plant vitality, nutrient content, yield production and carotenoid pigments in tomato cultivars, E-6203, UC-973 and VFN-8 was compared with the common adopted cultivars, peto 86 and Super Marmond. Cultivars response (growth and yield) to environmental local conditions did differ. Cultivar VFN-8 gave growth and yield than other tested cultivars. Cultivars treated with Alar gave an increase in early yield, total yield and yield components (Fruit number and fruit and fruit weight). External application of Alar to seedlings caused an appreciable increase in dry weight and vitality (chlorophyll retention test and cytokinin activity) as compared with the check. Seedlings treated with Alar contained more N, P, K and Mg than untreated control. Alar, also altered carotenoid pigments and soluble solids in tomato fruits. Tomato cultivars tested varied in their degree of response to Alar.
