Effects of different substrate mixtures on yielding potential of the Clery strawberry cultivar grown in high tunnel

Abstract

Effects of different substrate mixtures on more important parameters of generative potential in Clery strawberry cultivar were investigated. Researches were conducted in a high tunnel at the Experimental property of "Zeleni Hit" enterprise in Belgrade, during the period from 2005 to 2006. Planting was done in bags filled with 20 l substrate mixtures. Four plants were planted per a bag. Investigations included: the flowering and ripening time, number of fruitful stalk per tiller, total number of flowers and fruits per tiller, fruit weight and, accordingly, yield per tiller and square meter. Based on the most studied parameters, C, D, B and F substrate mixtures expressed a positive influence on earliness and plant productivity of the Clery strawberry cultivar. Therefore, they can be recommended for commercial strawberry growing as substrate culture in a two year production system.

U ovom radu je ispitivan uticaj sedam različitih supstratnih smeša na fenološke osobine i rodni potencijal sorte jagode Clery. Istraživanja su vršena u visokom tunelu na Demonstraciono-oglednom polju preduzeća "Zeleni Hit" iz Beograda, u periodu 2005-2006. godine. Sadnja je obavljena početkom avgusta 2005. godine u vreće zapremine 20 l supstratne smeše, sa gustinom sklopa od 8 biljaka/m2. Proučavanjem su obuhvaćene važnije biološke osobine sorte jagode Clery: vreme cvetanja i zrenja, kao i pokazatelji rodnog potencijala u funkciji različitih smeša supstrata. Na osnovu dobijenih rezultata, među ispitivanim supstratnim smešama pozitivan uticaj na ranostasnost, produkciju cvetova i plodova, oplodnju, masu ploda i prinos sorte jagode Clery ispoljile su supstratne smeše C, D, B i F, zbog čega se mogu preporučiti za širu primenu u kontejnerskom uzgoju jagode.
