Comparisons of fruit and seed yield among species of the family Cucurbitaceae grown on the vertisol

Abstract

In this paper was compared average fruit and seed yields of different varieties grown on the vertisol belonging to five species of the family Cucurbitaceae (melon, watermelon, summer squash, winter squash, butternut squah) based on the two-year data (2010 and 2011). Five genotypes of melon (Sezam, Cerovaca, Galia, Charentais, Ananas), five genotypes of watermelon (Crimson sweet, Top gun, Greybelle, Fantasy, Rosa), five genotypes of summer squash (Ezra, Opal, Beogradska, Fina, Romanesco), three genotypes of winter squash (Sedef, Domaća bela, Plovdivska siva) and two genotypes of butternut squash (Nektar, L2706) were used. The experiment was set up in Smederevska Palanka. After the production of seedlings in the greenhouse of the Institute for vegetable crops, plants were transfered and planted in the open field. Two characteristics were observed: fruit yield per hectare and seed yield per hectare. The main objective of this study was to identify the genotypes which could be recommended for the production on vertisol. Very significant differences of fruit and seed yield per hectare were found between the genotypes and years for melon, watermelon, summer squash and winter squash. The highest average fruit yield was recorded for genotypes: Cerovaca (melon), Fantasy (watermelon), Fina (summer squash), Plovdivska siva (winter squash) and L2706 (butternut squash).

Poređenje prosečnih prinosa ploda i semena razlicitih sorti gajenih na zemljištu tipa smonice u okviru pet vrsta iz familije Cucurbitaceae (dinje, lubenice, tikvice, tikve i muskatne tikvice) je izvršeno na osnovu podataka dvogodišnjeg ogleda (2010 i 2011). Korišćeno je 5 genotipova dinje (Sezam, Cerovaca, Galia, Charentais, Ananas), 5 genotipova lubenice (Crimson sweet, Top gun, Greybelle, Fantasy, Rosa), 5 genotipova tikvice (Ezra, Opal, Beogradska, Fina, Romanesco), 3 genotipa tikve (Sedef, Domaća bela, Plovdivska siva) i 2 genotipa muskatne tikvice (Nektar, L2706). Ogled je postavljen u Smederevskoj Palanci. Nakon proizvodnje rasada u staklenoj bašti Instituta za povrtarstvo izvršeno je rasađivanja biljaka na otvoreno polje. Posmatrane su dve osobine: prinos ploda po hektaru i prinos semena po hektaru. Osnovni cilj rada je bio da se odrede genotipovi koji bi mogli da se preporuče za gajenje na zemljištu tipa smonica. Utvrđene su veoma značajne razlike prinosa ploda i semena po hektaru između posmatranih genotipova i godina kod dinje, lubenice, tikvice i tikve. Najveći prosečni prinos ploda zabeležen je kod genotipova Cerovaca (dinja), Fantasy (lubenica), Fina (tikvica), Plovdivska siva (tikva) i L2706 (muskatna tikvica).
