Influences of amino acid chelate foliar fertilizer on growth and seed quality of hybrid tomato seeds

Abstract

The objective of this study was to test the application of amino acid chelate foliar fertilizers on the changes of growth, yield and quality of tomato seeds. The treatments consisted of two levels (FCB and FZP) of fertilizer formulas with two levels of concentrations (2 ml/l and 3 ml/l) weekly at vegetative stage and after flowering. The experiment was conducted at three production areas at Amphur Muang in Khon Kaen. Seed quality laboratory at seed processing plant, Faculty of Agriculture Department, Khon Kaen University and analysis the nutrient in various parts of the plant at Department of Soil Science, Faculty of Agricultural Technology, King Mongkut’s Institute of Technology Ladkrabang. Experiment in 2010 for a period of 10 months.There were not significant differences among treatments for plant height, number of fruits,seeds per fruitand 1,000-Seed weight.However, weekly application seemed to give higher yield than control treatment.And found that the number of the Blossum end rod per plant of a group that received fertilizer, Amino chelate fertilizer formula every 2 concentrationreduced than that of the original fertilizer formula. Weekly application of foliar fertilizers resulted in greater seed germination of more than 90%. Plant analysis indicated that most of the nutrients were accumulated in the plants and small amount of nutrients were trans-located to seeds especially for calcium and boron. Applications of both fertilizer formulas had positivecorrelations with seed weight, especiallythe only elements Cu, B andFe.Germination under laboratory conditions and greenhouse conditions, both before and after storage in control and ambient condition,indicating that the application of amino acid chelate foliar fertilizers could improve seed quality. Also found that the amount of bottom end rot of the tomato decreased when the leaves for fertilizer elements, especially P, K, Ca, Mn, Cu, Zn and B.
