AB  - Lettuce (Lactuca sativa L.) is one of the most popular leafy vegetables used in human nutrition. Owing to its nutrient and mineral content, and high concentrations of vitamins and fibers, lettuce is considered as beneficial for human health. The short growing season makes lettuce convenient for growth in hydroponic systems. This paper aimed to study the effects of different mineral fertilizers on development and chlorophyll content in lettuce cultivated in controlled hydroponic systems. The research was carried out during January-February 2024 at the Institute for Vegetable Crops Smederevska Palanka, Serbia. The commercial lettuce cultivar ''Jukebox'' was cultivated for 30 days in a peat substrate, in a hydroponic system with artificial illumination. For lighting, light-emitting diodes (LEDs) were used. Plants were illuminated with multispectral white light (350-700 nm) at the temperature of 23 ± 2ºC and photoperiod of 8/16h (day/night). The experiment was set up in three replicates. The treatments were: Commercial fertilizer (CHF) intended for hydroponic production and soluble mineral fertilizer (SMF), applied in two different EC rates (1.5 and 2.5 mS/cm). For the first 15 days, the experiment was watered every day for 15 minutes, later watering was done twice a day for 15 minutes at intervals of ten hours. After 30 days of cultivation in a hydroponic system, growth parameters (fresh plant mass, above ground biomass and number of leaves) and chlorophyll content were measured. The CHF treatment significantly (p≤0.01) increased the mass of the plant (13.94g) comparing to SMF treatment (9.79g) The values of leaf chlorophyll content was significantly higher on the CHF treatment (26.43 SPAD) comparing to SMF treatment (22.18 SPAD) on the lower level of probability (p≤0.05). Nevertheless, the differences in mass and chlorophyll content indicate that the nutrients in CHF are better used compared to the SMF treatment especially at the 1.5 mS/cm EC level.

AB  - U cilju proučavanja efikasnosti bioloških preparata u zaštiti paprika od prouzrokovačabakteriozne pegavosti lišća (Xanthomonas euvesicatoria), tokom leta 2023. godine, postavljenje ogled u stakleniku Instituta za povrtarstvo u Smederevskoj Palanci. Proučavana jeefikasnost komercijalno dostupnih bioloških preparate Serenade ASO, Erwix, Bakterije,Ekstrasol i Bacillomix. Kao standard korišćen je preparat na bazi bakar-hidroksida (Everest).Proučavanja su obavljena na sorti paprike Paraćinka. Preparati su primenjeni u sledećimkoncentracijama: Serenade ASO (4%), Erwix (2%), Bakterije (1,5%), Ekstrasol (1%),Bacillomix (1%) i Everest (0,5%). Eksperimentalni dizajn ogleda je potpuno slučajan plan u triponavljanja sa sledećim tretmanima: (a) biljke tretirane pojedinačnim preparatima i nakondva sata inokulisane suspenzijom bakterija; (b) biljke tretirane samo suspenzijom bakterija(pozitivna kontrola); (v) biljke tretirane vodom (negativna kontrola). Inokulacija je vršena ufenofazi 8-9 listova ručnom prskalicom sojem bakterije X. euvesicatoria KFB 1 (10ˉ8 cfu/mol).Nakon tretmana, biljke su pokrivene plastičnim kesama, radi održavanja visoke vlažnosti utrajanju 48 časova. Prvi simptomi su uočeni 10 dana nakon inokulacije, a efikasnost preparataocenjena je 3 nedelje posle inokulacije. Indeks oboljenja izračunat je preko površinenekrotičnih pega na lišću, pomoću Horsfall-Barratt skale, a efikasnost proučavanih baktericidaizračunata je korišćenjem Abbott-ove jednačine. Za statističku obradu korišćena je metodaanalize varijanse, a za pojedinačna poređenja tretmana korišćeni su Dunnett-ov i Duncan-ovtest. Intenzitet zaraze u kontroli je iznosio 53%. Na osnovu dobijenih rezultata zaključuje seda je najefikasniji bio preparat na bazi bakar-hidroksida (96%), dok su biološki preparatiispoljili slabiji stepen efikasnosti: Serenade ASO (71%), Bakterije (61%), Ekstrasol (61%),Erwix (55%), Bacillomix (54%). Među biološkim preparatima nije bilo statistički značajnerazlike dok je standardni tretman ispoljio značajno višu efikasnost. Treba naglasiti da jeeksperiment izveden u stakleniku bez klimatizacije pri visokim spoljnim temperaturama, što je moglo nepovoljno uticati na efikasnost preparata baziranih na biološkim agensima. Stoga jeu cilju poboljšanja efikasnosti ovih preparata, prilikom narednih ogleda, neophodnoobezbediti kontrolisane uslove, a takođe treba proučiti i različito vreme primene, kao iintegraciju sa drugim merama zaštite.
