Abstract

From 2009 year in Serbian agricultural legislative and practice introduced new type of fertilizers, so called other fertilizers and special products. This new type of fertilizers comprise, for example, phytohormones, amino acids and plant extracts. But, because the comprehensive surveys of influence of this new type of fertilizers on horticultural plants is still lacking in Serbia, we established trials. In those trials we investigated influence of 10 different fertilizers of this type on harvest and components of harvest in apple and tomato. The results of those trials discussed in context of physiological function of active ingredients of those fertilizers.

Od skora je ozvaničena u našoj poljoprivrednoj praksi upotreba tzv. drugih đubriva i specijalnih proizvoda, u koje spadaju i biljni hormoni, aminokiseline i biljni ekstrakti. Pošto još uvek u našoj praksi nema sistematskih i uporednih istraživanja dejstva ovih agrohemikalija na hortikulturne useve, postavljen je ogled u kome je ispitivano dejstvo 10 različitih đubriva ovog tipa na prinos i komponente prinosa jabuke i paradajza. Dobijeni rezultati komentarisani su obzirom na fiziološku funkciju jedinjenja, koja čine ovaj tip đubriva.
