UTJECAJ RAZLIČITIH TIPOVA SUPSTRATA NA INTENZITET RASTA PRESADNICA RAZLIČITIH HIBRIDA RAJČICE (Lycopersicon esculentum Mill.)
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
Genetic Variability of some Maize Inbred Lines (Zea mays L.)in Agroecological Conditions of Kosovo
The aim of this study, conducted during the years 2005 (Y1) and 2006 (Y2), was to investigate the variability and appearance of genotype reaction in maize inbred lines. In the investigation were included 10 maize inbred lines obtained from the University of Tirana- Albania, department of Agronomy. The experiment was based on a ranomized complete block design (RCBD) with three replications in the locality of Ferizaj. The variability and genotype reaction was analysed for quantitative parameters for plants as following: Ear height (EH); plant height (PH), ear leaf area (LA) and leaf area index (LAI). The experimental average values μ for investigated parameters were: EH was 60.46 cm, PH (169.88 cm), LA (446.2 cm2) and LAI (3.23 plant m-2) respectively. The inbred lines between them for EH at the first year (Y1) and the second year (Y2) had show the variability 52.59% and 43.16%, respectively. The highest value for EH was shown by inbred L4 (76.10 cm), which differs from the value μ for +25.86%. While the lowest value was recorded at the inbred L5 (44.30 cm) that difference was a reduction of -26.72%. In the Y2 the same values were repeated but with minimal differences. The maize inbred L7 for the Y1 had a greater total plant height (196.5 cm), while for the Y2 was obtained 206.7cm. The minimal average value for PH were shown by the inbred L8 and L2, while the total variability between all inbred lines for PH were Y1 (32.61%) and Y2 (36.55%) respectively. Average values of the two years investigation for ear leaf area (LA) were obtained by inbred L7 (544.1cm2 plant-1), whereas lowest values were showed by maize inbred L10 (356.9cm2plant-1). Variability between inbred lines was 41.95 %. The highest value of LAI was obtained for inbred L7 on coefficient 3.9 plant m2 (Y1) and 4.0plant m-2(Y2) whereas the lowest LAI was realised on maize inbred L10 (2.5 plant m-2) at the Y1, while for the Y2 was obtained at maize inbred L8 (2.6 plant m-2)
Assessment of morphological variability and chemical composition of some local pepper (Capsicum annuum L.) populations on the area of Kosovo
CONTENT OF MINERAL SUBSTANCES BETWEEN THE TWO ONION CULTIVARS
The purpose of two years of work was the determination of some chemical elements in onion (Allium cepa L.) between the two cultivars: Stuttgarter-Netherlands and cultivar of Prizren-Kosovo in different periods of planting and various preservations conditions of bulbs at room temperature and +5(°C).In the first experiment year is planted the seed while in the second year was made the bulb. Is ascertain is a difference between cultivars in the content of minerals substances
Assessment of morphological variability and chemical composition of some local pepper (Capsicum annuum L.) populations on the area of Kosovo
Seven local pepper populations (Capsicum annuum L.) from different geographical regions of Kosovo, were evaluated for morphological traits, chemical composition, and antioxidant contents using standard analytical techniques. All local peppers populations were characterized for different morphological traits from seedling emergence to crop maturity. The total genetic variation for plant height (PH) was 11.72 cm or expressed in relative values was 27.94 %. Average of leaf area (LA) per plant was 2308.38 cm2, while the lowest value for LA was 1136 cm2. Yield per plant ranged from 265 to 691 g plant-1. The acidity level was ranging from 1.44 to 1.61 %, carbohydrates varied greatly from 4.21 to 6.07 %. Vitamin C (as ascorbic acid) content in fresh fruit ranged from 65.544 to 520.51 mg 100g-1 of fresh mass. Minerals were of reasonable levels with Fe (15.31 mg kg-1), Ca (216.71 mg kg-1), Na (406.01 mg kg-1), K (1851 mg kg-1), and Zn (5.74 mg kg-1).</p
