Abstract

Cilj istraživanja bio je utvrditi utjecaj biostimulatora Actiwave, Humistar i Phylgreen na
mineralni sastav i prinos tržnih i udio netržnih plodova rajčice u hidroponskom uzgoju.
Dvofaktorijalni pokus proveden je 2019. godine na pokušalištu Zavoda za
povrćarstvo, Agronomskog fakulteta. Postavljen je po metodi slučajnog bloknog
rasporeda u tri ponavljanja. U pokusu su testirana dva rana hibridna kultivara rajčice:
'Alamina' i 'Vasanta' u četiri tretmana: kontrola (K), Actiwave (A), Humistar (H) i
Phylgreen (P). U odnosu na kontrolu pozitivan utjecaj biostimulatora na tržni prinos
ploda ostvaren je samo kod kultivara 'Alamina'. Najveći prinos tržnih plodova od
13,83 kg/biljci ostvaren je kod biljaka tretiranih Phylgreenom, zatim Humistarom dok
su kontrola (10,75 kg/biljci) i Actiwave (10,62 kg/biljci) ostvarile značajno manji
prinos. Sva tri biostimulatora, u svim terminima berbe, u oba kultivara, imala su
pozitivan utjecaj na akumulaciju većine makro i mikroelemenata u plodu rajčice, osim
magnezija i bakra. Značajno veći sadržaj N, P i Mg, a manji sadržaj Ca utvrđen je
kod kultivara 'Vasanta' u odnosu na kultivar 'Alamina', dok je sadržaj kalija bio
značajno veći samo u drugom uzorkovanju. Slična situacija je i s mikroelementima,
veći sadržaj Zn, Mn i Cu utvrđen je u svim uzorkovanjima, a Fe u prvom uzorkovanju
kod kultivara 'Vasanta' u odnosu na kultivar 'Alamina'.

Abstract (english)

The purpose of the research was to determine the effect of Actiwave, Humistar and
Phylgreen biostimulants on the mineral composition and yield of marketable and
share of nonmarketable tomato fruits grown in hydroponic system. A two-factorial
experiment was conducted in 2019 at the experimental field of the Department of
Vegetable Crops, Faculty of Agriculture. It was set up according to the random block
design in three replications. In the experiment, two early hybrid tomato cultivars were
tested: 'Alamina' and 'Vasanta' in four treatments: control (K), Actiwave (A), Humistar
(H) and Phylgreen (P). In relation to the control, the positive impact of the
biostimulants on the marketable fruit yield was achieved only in the 'Alamina' cultivar.
The highest yield of marketable fruits of 13.83 kg/plant was achieved in plants treated
with Phylgreen, followed by Humistar, while the control (10.75 kg/plant) and Actiwave
(10.62 kg/plant) achieved a significantly lower yield. All three biostimulants, in all
harvest times, in both cultivars, had a positive impact on the accumulation of most
macro and microelements in the tomato fruit, except for Mg and Cu. A significantly
higher content of N, P and Mg, and a lower content of Ca was found in the 'Vasanta'
cultivar compared to 'Alamina' cultivar, while the potassium content was significantly
higher only in the second sampling. The situation is similar with microelements, a
higher content of Zn, Mn and Cu was determined in all samplings, and Fe in the first
sampling in the 'Vasanta' cultivar compared to 'Alamina' cultivar.
