The results of chemical analysis for four new genotypes of flat-leaf parsley developed at the Centre for Vegetable Crops, Smederevska Palanka (Serbia) were shown in this paper. The chemical analysis ...of new line of flat-leaf parsley PPL-1 performed during the three-year period showed that the percentage of the dry matter content was higher by 8% than the standard cultivar Domaci Liscar. The content of minerals and sugar in the leaf of the new line was increased by 9% and 6%, respectively in relation to the standard cultivar. The line PPL-1 forms a thin, forked root and has a very dense rosette with over 50 leaves on medium compact stems. All observed genotypes had greater content of dry matter, sugar and minerals in leaf, than standard. The aim of this study was to test the quality of new flat-leaf parsley lines in order to develop new cultivars.

During 2004 in the Centre for Vegetable Crops in Smederevska Palanka, Serbia, the influence of substrate on growth, development, dry matter content, N, P2O5, K2O in the tomato seedling was studied. ...Mixtures of disinfected compost of peat of domestic and foreign origin substrates and zeolites enriched with easy available nutrition elements and natural biostimulators (humates) were used. The seedling was produced in containers by applying the speedling method. The early tomato variety Balkan F1 was grown. The obtained results showed significant differences of studied substrates and especially of a mixture of peat and fertilized zeolites. In phase of seedling, plants formed a great number of permanent leaves on these substrates. Plants had a greater weight of root, stalk, and leaves. Plants buttoned earlier and flowered.
The influence of zeoplant (fertilizer produced of natural zeolite) on earliness and the total yield of tomato has been investigated. The mixture of compost and zeoplant in producing transplants has ...influenced the increasing of early, medium early and total yield of tomato. Growing transplants in the mixture of compost 75 and zeoplant 25 with early, medium early and total yield have been accomplished. Plants that have been grown in the mixture of compost 80 and zeoplant 20 have been early.
This study, and similar studies performed on other vegetable test crops, is aimed at the production of high quality substrate for vegetable production. The base for the preparation of these ...substrates is Pester peat, which is, by the rank of its physical-chemical qualities, classified in the highest quality group in the world. In addition to peat, for the experimental production of substrates, altogethert forty-five, we applied sheep manure, CaC03, zeolite and a complex mineral fertilizer 15:15:15, in various combinations and quantities. To be able to determine whether the degree of peat mineralization affects the quality of pepper seedling production, we produced the substrates in which the peat component is composed only of mineralised peat, semi-mineralized and non-mineralized peat. Based on the test results, it was concluded that the substrate quality was not affected by the ratio of the mineral and organic peat in it, but the quantity of the added sheep manure and mineral fertilizers. The effect of added quantities of ground limestone and zeolite did not affect the habit of pepper seedlings, which does not mean that the higher quantities of these materials would not have a positive effect. We shall test it in our future experiment.
During 2005 and 2006 in the Center for Vegetable Crops in Smederevska Palanka, Serbia, the impact of various substrates on growth, development and buttoning of tomato and pepper seedling was ...researched. The mixture of disinfected compost (produced in the Center for Vegetable Crops - Smederevska Palanka, Serbia), domestic peat (Dalashum from Tutin, Serbia), vermicompost (lubrihumus from Sremska Mitrovica, Serbia) and Zeoplant (enriched zeolite, produced by mine Nemetali - Vranjska Banja, Serbia) have been researched. The substrates and mixtures have been compared to foreign substrates. The seedlings was produced in styropore containers. Tomato variety Balkan F1 and pepper Zupska Rana were the material in this research. The results showed the significant differences of researched substrates, especially substrate mixture and enriched zeolite. Plants in these substrates were higher, formed more permanent leaves, buttoned earlier. Plants in substrate mixtures with zeolite had larger root, stalk and leaf mass.
