Abstrakt
Antud bakalaureusetöö eesmärgiks oli uurida leheväetiste mõju aedmaasika sortide
‘Sonata’ ja ‘Elianny’ saagile ja vilja massile. Leheväetuskatse viidi läbi Lõuna-Eestis teise
aasta maasikaistandikus. Leheväetise variandis anti väetist viis korda, kontrollvariandis
pritsiti lehtedele samal ajal vett. Mõlemaid variante väetati ja kasteti ka
tilkkastmissüsteemi kaudu. Tulemustest selgus, et leheväetis mõjutas erinevate sortide
saaki erinevalt- mõju sordile ‘Elianny’ oli suurem kui mõju sordile ‘Sonata’. ‘Elianny’
lehtedes esines vasepuudus ja ‘Sonata’ lehtedes oli kaltsiumi-, tsingi- ja
magneesiumipuudus sõltumata leheväetise kasutamisest. Leheväetiste kasutamine ei
suurendanud antud katses statistiliselt oluliselt vilja massi. Leheväetiste kasutamine
suurendas `Elianny` puhul statistiliselt oluliselt turustatavat saaki. `Sonata` puhul oli
leheväetistega variandis märgata küll tendentsi saagitõusule, kuid statistiliselt olulist
erinevust võrreldes kontrollvariandiga ei olnud. Leheväetiste kasutamine oli antud katses
siiski majanduslikult tasuv mõlema sordi puhul.
This bachelor's thesis has been drawn up to investigate the effect of foliar fertilizers on the yield and fruit weight of the strawberry cultivars 'Sonata' and 'Elianny'. The foliar fertilization experiment was conducted in Southern Estonia in second year strawberry plantation. Foliar fertilization was used five times while control treatment was sprayed with water on the leaves at the same time. Both treatments were fertilized and irrigated also with a dripping system. The results showed that foliar fertilizers affected the yield of different cultivars differently - the effect on 'Elianny' was greater than the effect on 'Sonata'. 'Elianny' leaves showed a lack of copper, and 'Sonata' had a lack of calcium, zinc and magnesium, regardless of the use of foliar fertilizers. The use of foliar fertilizers did not significantly increase the weight of the fruit in this experiment. The use of foliar fertilizers resulted in a statistically significant increase in marketable yields for 'Elianny'. In the case of `Sonata' foliar fertilization treatment showed a tendency to increase yield, but there was no statistically significant difference compared to the control. However, the use of foliar fertilizers in this experiment was economically viable for both cultivars.
