Obična heljda (Fagopyrum esculentum Moench) posljednjih godina privukla je veliku pozornost zbog visoke prehrambene vrijednosti i ljekovitih svojstava. Ova kultura ima dugu povijest uzgoja u sjeverozapadnoj Hrvatskoj, a posebno je interesantna u sustavu ekološkog uzgoja. Posljednjih godina raste interes za proizvodnjom i konzumiranjem heljde, no problem predstavlja nedostatak odgovarajućeg sjemenskog materijala. Naime na sortnoj listi Republike Hrvatske nema niti jedne upisane sorte heljde, te se sadašnja proizvodnja temelji uglavnom na sjemenu tradicijskih kultivara (lokalnih populacija) te na uvozu stranih (uglavnom slovenskih) sorata od strane vlasnika OPG-ova. Cilj ovog rada je informirati stručnu javnost o utjecaju načina proizvodnje i roka sjetve na morfološka i agronomska svojstva tradicijskog kultivara heljde Varaždinska. Na osnovu rezultata ovog istraživanja nije utvrđena značajna razlika tradicijskog kultivara u odnosu na strane sorte ni u jednom od mjerenih morfoloških (visina biljke, broj grana po biljci i broj cvatova po biljci) i agronomskih (masa zrna po biljci i masa 1000 zrna) svojstava. Način proizvodnje (konvencionalni, ekološki) također nije značajno utjecao na prosječne vrijednosti mjerenih morfoloških i agronomskih svojstava, iako je utvrđena veća vrijednost morfoloških svojstava u ekološkoj proizvodnji.; Due to its high nutritional value and medicinal properties buckwheat (Fagopyrum esculentum Moench) has attracted increasing attention in recent years. This crop has a long history of cultivation in northwestern Croatia. There is special interest in growing buckwheat in organic cropping system. In recent years, interest on the production and consumption of buckwheat is growing, but the problem is the lack of appropriate seed material. Not a single variety of buckwheat is registered on the variety list of the Republic of Croatia, and the current production is based mainly on seeds of traditional cultivars (local populations) and on the import of foreign (mostly Slovenian) varieties by family farm owners. The aim of this paper is to inform the professional public about the impact of cropping systems and sowing dates on the morphological and agronomic traits of the traditional buckwheat cultivar Varaždinska. Based on the results of this research, no significant difference was found between the traditional cultivar in relation to foreign varieties in any of the measured morphological (plant height, number of branches per plant and number of inflorescences per plant) and agronomic (grain weight per plant and 1000 grain weight) traits. The cropping systems (conventional, organic) also did not significantly affect the average values of the measured morphological and agronomic traits, although a higher value of morphological traits in organic cropping system was found.
