| Abstract: | The investigation was carried out to explore the possibilities of using a slowly soluble form of micronutrients for production of greenhouse tomatoes Lycopersicon esculentum Mill. Experiments were carried out in the greenhouse using the variety Tropic. The effects of different rates of different coarse frits mixed in various media were studied. These treatments were studied on a two crop system with the plants being grown from August to December for the fall crop, and from January to June for the spring crop. The parameters statistically analyzed were: the number of #1 fruit, the size of #2 fruit (ounces), the number of culls, the pounds of #1 fruit per plant, pounds of #2 fruit per plant, and pounds of culls per plant. From these fata the marketable fruit and total yield were derived. None of these parameters showed statistical significance for any treatment in the fall crop 1974. However, the spring crop 1975 showed statistical significance for several parameters between half the treatments. Tissue analyses were also made on the spring crop 1975. There was no statistical difference between the controls for the various media which received a complete nutrient solution. The spring crop 1975 offers evidence that coarse fritted trace elements may be used to supply micronutrients, except boron, with no significant difference in total yield from a soluble source of micronutrients. |
