dc.description.abstractUždarame grunte ekologiškai auginamų pomidorų tyrimai atlikti 2014 metais polietilenu dengtame privačiame šiltnamyje (Alytaus mieste). Tyrimui parinkti pomidorų hibridai Loretto H, Buran H, Gualdino H, Rally H, Sparta H, Esmira H, Fuji Pink H. Darbo tikslas – įvertinti ekologiškai auginamų pomidorų derlingumą ir atsparumą grybinėms ligoms nedideliuose šiltnamiuose. Sustratas paruoštas maišant lygiomis dalimis neutralizuotas durpes, kompostą bei šiltnamio žemę. Pridėta organinių trąšų Activit, žuvų miltų, kalio sulfato, kalio magnezijos (N168P52K325Ca204) ir mikroelementų (B, Fe, Mn, Zn, Mo) tirpalo. Vienam pomidorui skiriama 20 litrų grunto, o sodinimo tankis – 2 daigai/m2. Auginama ant vieno stiebo 6 kekės. Augimo ir derėjimo metu kartą per savaitę buvo papildomai tręšiama fermentuotų žolių ištrauka. Pomidorai auginti 40 cm pločio polietileno juostose, mulčiuojant šviežiai pjauta gazonine žole. Papildomai taikytos augalų apsaugos priemonės – vario sulfatas ir pieno, muilo bei jodo mišinys. Tyrimo metu buvo nustatytas vaisių skaičius kekėse, vidutinis vaisių svoris, ankstyvas derlius ir bendras derlingumas išauginus 6 kekes ant vieno augalo. Nustatyta, kad subalansuotame substrate, papildomai tręšiant raugintomis žolėmis ir naudojant augalų apsaugos priemones, pomidorai augo ir vystėsi gerai. Didžiausias ankstyvas derlius gautas hibridų Loretto, Buran ir Rally, o suminis didžiausias derlius − hibridų Rally, Buran ir Esmira. Daugiausiai vaisių kekėse suformavo Loretto, o didžiausius pomidorus išaugino Esmiralt
dc.description.abstractThe investigation of organically grown tomatoes was carried out in 2014 at the private polyethylene greenhouse in Alytus town. Hybrid tomato breeds have been selected for the experiment: Loretto H, Buran H, Gualdino H, Rally H, Sparta H, Esmira H, Fuji Pink H. The aim of the investigation was to assess the fertility of organically grown tomatoes and their resistance to fungal diseases in the small greenhouses. The substrate for the experiment was prepared by mixing the equal parts of peat, compost and soil from the greenhouse. Additionally, substrate was supplemented with organic fertilizers (Activit, fish meal, potassium sulfate, potassium magnesia (N168P52K325Ca204) and micronutrients (B, Fe, Mn, Zn, Mo) solution. The 20 liters of the prepared soil substrate was set up for each one tomato growing and the planting density of two plant seedlings to one square meter have been used. Six bunches were grown on each one single stem of tomato plant. Fertilization with the fermented herbal solution once per week was applied during the growth and fruiting period. Tomatoes were grown in the 40 cm wide plastic strips adding up the fresh cut grass mulch. Additionally, copper sulphate and milk-soap-iodine mixture have been applied as a plant protection means. The number of fruits in the bunch, the average fruit weight, early yield and total yield when plant have had six bunches on each one single stem have been estimated. It was found that tomatoes grew and developed well in the balanced soil substrate when additional fertilization with fermented herbal solution and plant protection means applied. The hybrid varieties Loretto, Buran and Rally have produced the highest early yield and the hybrids Rally, Buran and Esmira − total maximum yield. The Loretto hybrid has formed a highest number of fruits in the bunch and the Esmira hybrid grew the largest tomatoesen
