RESPONSE OF 3 SWEET-PEPPER CULTIVARS TO BIOZYME UNDER UNHEATED PLASTIC HOUSE CONDITIONS

Two experiments were carried out in an unheated plastic house to study the response of three pepper (Capsicum annuum L.) cultivars, i.e. 'Blemont', 'Domino' and 'Atol', to Biozyme, applied at 0, 1 and 2 ml l(-1) at flower initiation followed by two sprays at an interval of 21 days. Biozyme is an extract of vegetable origin that contains, in ppm, 32.2 indoleacetic acid (IAA), 32.2 GA(3), 83.2 zeatin, 4900 Fe, 1200 Mn, 3000 B, 3700 Zn, 1400 Mg and 4400 S. Results indicated that 'Blemont' was the best cultivar regarding the number of early and total fruits, weight of total yield, while cv. 'Atol' gave the highest values of early yield, average fruit weight, and ascorbic acid in fruits. Two millilitres of Biozyme gave the best results with regard to height and weight of plants, number and weight of total fruits, and ascorbic acid in fruits. However, the highest average of fruit weight was produced by 1 mi Biozyme. Generally, Biozyme significantly increased early yield compared with untreated plants with no significant differences between the two concentrations used.
