Abstract

Tomato (Lycopersicum esculentum Mill.) Is a horticultural commodity. Tomato production is influenced by various factors including seed quality. Low quality seeds are old seeds or seeds that have passed the threshold of the planting period, so that they cannot adapt well to their cultivation environment. One effort to overcome the deterioration of the quality of old seeds is to utilize a magnetic field. Magnetic fields can have a positive influence on plants. In this study the study of the influence of exposure to magnetic fields with different magnetic field strengths on old seeds. This research was conducted using a completely randomized design (CRD) with one factor, namely the treatment of magnetic field exposure for 7 minutes 48 seconds with 3 levels of treatment namely 0.1 mT, 0.2 mT and 0.3 mT. This study uses two controls, namely positive control (new seed), and negative control (old seed). Both controls were not given magnetic field treatment. The generative growth parameters observed were chlorophyll content, carbohydrate content, fruit formation speed. Data were analyzed in various ways (anara) and if there were significant differences between treatments, they were further tested with Tukey’s at α = 5%. The results of this study indicate that the magnetic field strength can improve metabolism in old seeds so as to produce plants whose generative growth is better than control. The best magnetic field strength to improve old seed metabolism is 0.2 mT. Keyword: growth, magnetic fields, old seeds, tomatoes.
