Seed germination, growth, flowering and yields of kiwano (Cucumis metuliferus E. Meyer Ex. Naudin) were examined in eastern Slavonia during 2021 growing season. The objective of this study was to determine agro-morphological diversity within kiwano growing under different weed management practices and sowing time. The experiment was arranged as a 3 x 3 factorial design with three replications. Factors included three weed management options (wheat straw mulch, cultivation and un-weeded control) and three planting dates (early, mid and late May). Atypical summer weed community that develops during experiment dominated with bristly foxtail (Setaria verticilata (L.) P. Beauv.) and redroot pigweed (Amaranthus retroflexus L.) while the others were with lower relative density and frequency per unit area and with the lower impact on the crop. Weed control was very effective compared to weedy check. However, sowing date appears as a critical factor in kiwano production, influencing not only emergence, growth and flowering, but also fruit number and size. This study concluded that mid sowing time and cultivation as a weed control measure has a highest agronomic potential for a kiwano production following by mid and early sowing time with mulch as a weed control measure.

Meyer Ex. Naudin). Cilj istraživanja bio je utvrditi agromorfološke razlike pri proizvodnji kivana uzgajanog s razlicitim sustavima kontrole korova te razlicitim rokovima sjetve. Pokus je postavljem kao 3 x 3 faktorski plan s tri ponavljanja. Faktori su ukljucivali tri varijante suzbijanja korova (primjena slame kao malca, kultivacija i kontrolna zakorovljena varijanta) te tri roka sjetve (rani, srednji i kasni). Tijekom pokusa se razvila tipicna zajednica ljetnih korova u kojoj su dominirali pršljenasti muhar (Setaria verticilata (L.) P. Beauv.) i oštrodlakavi šcir (Amaranthus retroflexus L.), dok su ostali korovi bili niske relativne gustoce i frekvencije po jedinici površine i slabog utjecaja na uzgajane biljke. Tretmani suzbijanja korova bili su vrlo ucinkoviti u usporedbi sa zakorovljenom kontrolom. Medutim, vrijeme sjetve pokazalo se kao kritican faktor u proizvodnji kivana, i imalo je utjecaja ne samo na nicanje, rast i cvatnju, vec i na broj i velicinu plodova. Zakljucno, srednji rok sjetve i kultivacija kao mjera suzbijanja korova pokazali su najveci agronomski potencijal za proizvodnju kivana, a slijede srednji i rani rok sjetve uz primjenu malca za suzbijanje korova.
