Investigational results of new substrates in pepper nursery plants production

Abstract

Nursery plants were studied on the domestic peat 'Gaj' originating from the Banat village Gaj. Different amounts of mineral fertilizers were added to peat using the formula 20:20:20 + microelements. Thus 5 substrates were prepared: 1) Gaj + 1.25 g of fertilizers; 2) Gaj + 1.85 g of fertilizers; 3) Gaj + 2.5 g of fertilizers; 4) Gaj + 3.12 g of fertilizers and 5) Gaj + 3.75 g of fertilizers (g on 1 l of peat). Peat only (without fertilizers) was used as control. Three nursery plant properties were studied: plant height, number of leaves per plant and plant weight (ground parts). The effect of fertilizers on nursery plants was positive. Substrates with fertilizer amounts 1.85 g and 2.5 g/l of peat were the most effective. Favorable results were also achieved using 1.25 g of fertilizer amounts in the substrate. Therefore, the best substrates are recommendable for use in pepper nursery plant production.

Supstrati su pripremani od treseta 'Gaj' i kompleksnog mineralnog đubriva (20:20:20 + mikroelementi). U treset su unete različite količine đubriva (od 1,25 do 3,75g/l). Ispitan je uticaj supstrata na sledeće osobine rasada: visinu biljke, broj listova po biljci i masu biljke (nadzemni deo). Najbolje rezultate ostvarili su supstrati sa umerenim količinama đubriva (2,50 i 1,85g). Supstrati u koje je dodato 3,12 i 3,75g đubriva nisu pogodovali rasadu paprike (visoka koncentarcija hraniva).
