BIOSTIMULANTS IMPLEMENTATION IN STRAWBERY PRODUCTION

Uspješan uzgoj jagode (Fragaria L.) podrazumijeva pravovremene agrotehničke i pomotehničke zahvate u nasadu. Podizanje kvalitete proizvodnje jagoda može se postićiupotrebom ekoloških gnojiva i dopuštenih biostimulatora koji utječu na rast i razvoj biljaka. Cilj ovoga rada bio je primijeniti ekološki prihvatljiva sredstva (organsko gnojivo i biostimulatore) u različitim varijantama pri uzgoju jagoda sorte Clery te utvrditi njihov učinak na kvalitetu sadnica i prinos jagoda. Prinos jagoda utvrđen je mjerenjem mase i broja jagoda tijekom plodonošenja u četiri ponavljanja, a na kraju vegetacije je utvrđena duljina nadzemnog dijela, duljina korijena te ukupna duljina biljke kao i masa nadzemnog dijela, masa korijena u svježem stanju i ukupna masa biljke, a zatim broj listova i broj vriježa. Dobivene vrijednosti ukazuju na pozitivan utjecaj biostimulatora na sva mjerena svojstva.Successful cultivation of strawberries (Fragaria L.) requires real agrotechnical and auxiliary works in the orchard. Quality strawberry production can be achieved by applying organic fertilizers and permitted biostimulants for plant growth and development. The aim of this study was to apply ecologically permitted agents (organic fertilizer and biostimulants) in different variants in the cultivation of strawberry cultivar Clery, and to determine their effect on seedling quality and strawberry yield. Strawberry yield was determined by measuring the weight and number of strawberries during fruiting in four replications, at the end of vegetation the length of the aboveground part, the length of the roots, the total length of the plant as well as the mass of the aboveground part, the mass of fresh roots and the total leaves and number of strawberry stalks. The obtained values and results indicate a positive effect of biostimulants on all measured properties
