Fertilizer effects on the container production of tomato seedlings

Abstract

In these researches the plan is to look at the effect of different fertilizers on the quality of tomato seedlings made for open field production (cv. roker). Tomato nursery were grown in containers with 104 openings and saved during the seeding period with three types of fertilizes with: fitofert kristal, fitofert humisuper and slavol. They were used with different percentages, and the time of use was after sowing, with the appearance of first leaf that continued during those seven days from sprouting until the end of the seedling period. The following parameters were determined: plant height (cm), number of leaves per plant, stem thickness (mm) and the weight of the plants’ above-ground parts (g). With all of the tested parameters the best results were made with continuous usage of fertilizers. In the container production of tomato seedlings, where the seedlings was being produced in small volume of substrates in short period of time, usage of mineral fertilizers gives overall better results than organic-mineral and microbiological.
