Tomato together with pepper is main vegetable crop in Kosovo. Yearly
tomato is planted on around 2.000 ha. Quality preparation of seedling is
important precondition for successful production of tomato. Substrates used
in Kosovo for production of tomato seedlings are different (it is same for
other different vegetables). With the aim to test the effect of feeding
substrate in growth and development of seedlings during different phases
three types of substrates were used: loam (soil mixed with decomposed
organic manure 50:50) - SP1, Peat 100% - SP2, and mixed loam + peat
(50:50) - SP3. These substrates were tested in three tomato hybrids
(Graziella, Big Beef and Amati). Design of experiment was based on case
block system with three repetitions for every treatment (RBDE). Analysis
included: roots fresh weight, root length, seedling height, internodes length,
fresh stalk weight. Regarding roots fresh weight and roots length different
results were achieved for different cultivars. Average general values for all
three cultivars were 8.72 g and for length 22.22 cm. Hybrid Graziella for two
parameters realized average values: maximal value for root fresh weight of
13.90 g (SP2) and root length of 27.83 cm (SP1). Amati achieved lower
values of weight in substrate (SP3) 5.03 g. Graziella achieved lower values
for root length in substrate SP1 18.23 cm. Difference for root fresh weight
and roots length were highly significant at level 0.05 and 0.01, respectively.
Also for seedling height and distance between nodies the results between
substrates were significant at the level 0.05 and 0.01.Rajčica i paprika najvažnije su povrtne kulture na Kosovu. Rajčica se godišnje
uzgaja na oko 2.000 ha. Kvaliteta proizvedenih presadnica važna je predispozicija za
uspješnu proizvodnju rajčice. Supstrati koji se na Kosovu koriste za proizvodnju
presadnica su različiti. U cilju utvrđivanja utjecaja supstrata na rast i razvoj presadnica
rajčice u različitim fazama korištena su tri tipa supstrata: ilovasto tlo SP1 (tlo
pomiješano s razgrađenom organskom tvari 50:50), treset SP 2 i treset pomiješan s
ilovastim tlom SP3 (50:50). Supstrati su testirani na tri hibrida rajčice (Graziella, Big
Bef i Amati). Pokus je postavljen po shemi običnog bloknog rasporeda u tri ponavljanja.
Analizirana je masa svježeg korijena, dužina korijena, dužina presadnice, dužina
internodija i težina svježe stabljike.
Za težinu svježe stabljike i dužinu korijena ostvareni su različiti rezultati kod
različitih hibrida. Prosječna težina svježe stabljike za sva tri hibrida bila je 8,72 g, a
dužina korijena 22,22 cm. Hibrid Graziella je imao najveću masu svježeg korijena 13,90
g u supstratu SP2 i najduži korijen 27,83 cm u supstratu SP1. Hibrid Amati imao je
najnižu masu svježe stabljike u supstratu SP3 a bila je 5,03 g dok je Graziella imala
najmanju dužinu korijena pri uzgoju u supstratu SP1 od svega 18,23 cm. Statistički visoko značajne razlike između supstrata utvrđene su za masu svježeg korijena, njegovu
dužinu kao i dužinu internodij
