Izvleček
V nalogi smo proučevali vpliv različnih substratov in rastnih razmer za čim boljšo uspešnost gojenja kalic (mikro-zelenjave). Uporabili smo dva rastlinska materiala – grah in ohrovt, ki smo ju posejali v vermikulit, 2 cm kameno volno, 4 cm kameno volno in šoto. Po tri pladnje vsakega medija smo položili na okenske police severne (senčne) in južne (sončne) lege okna na katedri za sadjarstvo, vinogradništvo in vrtnarstvo, oddelka za agronomijo Biotehniške fakultete v Ljubljani. Tekom rasti smo kalice opazovali in zapisali fenotipske spremembe. Dvakrat dnevno so bile kalice orošene, substrati pa zaliti, da smo dosegali optimalno vlažnost substrata. Petnajsti dan po setvi so bile kalice ohrovta pripravljene za rez, sedemnajsti dan pa kalice graha. Vsako ponovitev smo stehtali, prešteli količino semen/zrn oziroma zraslih rastlinic. Desetim naključnim poganjkom smo izmerili višino, vsebnost klorofila in topno suho snov (°Brix). Kalicam smo ob rezi stehtali maso pridelka, odvzeli del za določitev mase suhega vzorca, pogledali prekoreninjenost medija, izmerili višino kalic (pri grahu tudi dolžino vitic). Z meritvami smo ugotovili, da je najugodnejša rast za kalice v šotnem substratu, najmanj pa v 2 cm kameni volni. Za bolj optimalno stran neba se je izkazala severna, torej senčna stran. Tekom raziskave so se pojavile pozitivne in negativne lastnosti določenega substrata.

Naslov:Comparison of different media and conditions for growing microgreens
Izvleček:
The influence of various substrates and conditions for growing microgreens was evaluated in order to establish optimal protocols for this type of culture. Two vegetables were tested - peas and kale and their seeds were sown in vermiculite, 2 cm thick rock-wool, 4 cm thick rock-wool and peat. Two locations for growing microgreens were proposed: north exposed windowsill (shady spot) and south exposed windowsill (sunny spot). Three trays of each medium and each vegetable type were placed on the windowsills at the Chair of Fruit growing, Viticulture and Vegetable growing, Department of Agronomy, Biotechnical Faculty in Ljubljana. Phenotypic changes were recorded during the growth. Microgreens were sprayed twice a day and at the same time substrates were watered in order to achieve optimal moisture content. On the fifteenth day after the sowing kale sprouts were ready for cutting. Pea microgreens were harvest-ready on the seventeenth day after sowing. Each repetition was weighed and the number of seeds or grown plants was counted. The height, chlorophyll content and soluble dry matter (° Brix) of 10 random shoots of each vegetable type was recorded. The weight of the entire crop per repetition was recorded, samples were taken to determine dry mass and root development was determined. Moreover, the height of kale microgreens and the length of pea tendrils were recorded. The results indicate that peat is the best substrate for growing microgreens. On the other hand, 2 cm thick rock-wool yielded least favorable results. North-exposed windowsill was superior to south-exposed windowsill. Positive and negative properties of tested substrates were determined in the study.
