Improving quality seeds and seedling growth for organic and conventional tomato production

Abstract

The world is a growing tendency for reduced application of chemicals and increasing use biological resources in order to protect the environment. In agricultural production in general, ar­ in the seed production and the tendency is reduced by the application of chemical agents ar their treatment on the seeds. In this study were investigated by two different varieties of toma (Rio Grande and Saint Pierre) and were treated with the following treatments: 1. Zink (Zn - 0.5% • Boron (B- 0.025%), 3. Coveron (Glomus mosseae, Glomus intraradices and Trichoderma atroviride Mix - Coveron (Glomus mosseae, Glomus intraradices and Trichoderma atroviride) + Zink (Zn - 0.5 + Boron (B - 0.025%), 5. Untreated control. After a treatment on the seeds and in the hot bed determined energies and total germination, in conformance with the Regulations on the Qua of seeds of agricultural plants (Official Gazette of Yugoslavia 47/87). Also determined and seedl" vigor (the primary root length and shoot length). In cultivar Saint Pierre determined an increase 21% germination In the embodiment of the treatment of seed Coveron, compared to the cont The largest increase in germination of 6%of it was found in the cultivar RioGrande in a variant v. Mix, compared to the control.When it comes to the totalgermination in the cultivar Saint Pierre la est increase over the control of 13% was observed in the variant with thetreatment of the seed t::. Mix. In cultivar Rio Grande largest increase seed germination of 7% have been found in the var;: with thetreatment mix, and Zn included, in comparison to the control.In cultivar Saint Pierre largt" effect on the increase in shoot length of 3.2 cm or 60.4%, determined on the embodiment to • application B, a variant in relation to control. In cultivar RioGrande largest increase in shoot Ieng 1.0 cm or 14.3%, was found in the variant with the treatment mix, as compared to the control. increase in the lengthof theprimary rootmost influenced by the treatment of the seed withCover'" included in bothcultivars. in Saint Pierre of 1.2 cm or 28.6%, respective ly, in the cultivar RioGrande cm or 30.0%. We couldsay that almost all treatments showed improvements in certain paramet which were followed in relation to the control,and may findusein the treatment of tomato seeds• both organic and conventional production. The work was realized within the projectsTR31057 and TR31018, Ministry of Education, Sciel"' and Technological Development of Republic of Serbia.
