Influence of container cell capacity on the properties of marigold seedlings

Abstract

Container seedling production being intensive has a number of advantages and is used in both vegetable and flower production. The 'speedling system' i.e. the system of polystyrene and polypropilene containers with pots of different volumes for substrate and seed sowing is known to be the most rational and practical container production system. The researches were conducted during 2007 in the greenhouse of the Faculty of Agriculture in Belgrade. The seedlings of marigold were grown in containers with different cell sizes (7,3; 20; 33; 80 cm3). The following parameters of seedling quality were analyzed: plant height, number of lateral branch, plant mass and root weight. The most favorable marigold seedling quality was obtained in the largest sized containers cells 80 cm3.

Kontejnerska proizvodnja rasada kao intenzivni način proizvodnje rasada ima niz prednosti u odnosu na klasičnu, i svoju primenu je odavno pronašla u povrtarskoj i cvećarskoj proizvodnji. Od svih kontejnerskih sistema proizvodnje, najracionalniji i najpraktičniji se pokazao 'speedling sistem', odnosno sistem polistirenskih i polipropilenskih kontejnera sa ćelijama različite zapremine u koje se stavlja supstrat i vrši setva. Istraživanja su sprovedena tokom 2008. godine u stakleniku Poljoprivrednog fakulteta u Beogradu. Rasad kadifice je proizveden u kontejnerima sa različitim zapreminama ćelija (7,3; 20; 33; 80 cm3). Analizirani su parametri kvaliteta rasada: visina biljke, broj bočnih grana, masa biljke i masa korena. Najbolji kvalitet rasada kadifice dobijen je proizvodnjom u kontejnerima sa najvećom zapreminom ćelije od 80 cm3.
