Abstract

The field experiment was conducted at the General Commission for Scientific Agriculture Research (GCSAR), Homs Research Center during 2017/2018 and 2018/2019 seasons, to compare production and quality traits of five monogerm fodder beet varieties, i.e. Caribou, Varians, SV Four 16, Tarine and Lipari. The experiment was sown in winter (mid of February and mid Mars). A split plot design was used, with three replicates. The results showed the superiority of mid-February sowing date  to get higher values of production traits (root and shoot yields) for all studied varieties. While sowing fodder beet in mid-Mars is better if the purpose was to reserve the crop as dry forage and give it later for the animals, because this date gave higher dry matter. The results also showed that the monogerm variety Lipari was the best for most of the production and quality traits as compared with the other varieties.  The study recommend growing fodder beet in mid-February to mid-Mars under Homs conditions, but after conducting a complementary researches concerns the other agricultural treatments as, lifting time, plant spacing,  rate of fertilizer and applications …etc, and also to test more monogerm and multigerm new varieties from different sources.

Key words: Fodder beet, Sowing date, Production traits, Quality traits, Varieties.

Abstract

The experiment was conducted to study the effect of sowing the carrot (Daucus carota. Var. Nantes) on three dates (24/9, 8/10 and 23/10) and two densities: high (80) plants/m2 and low (40) plants/m2 under the conditions of Hama governorate, according to the split design. The early sowing showed a significant superiority over the other dates in all the studied traits (germination; maturity; length of leaves; length, diameter and weight of root; number of leaves per plant; fresh plant weight, and marketable productivity). The low density was significantly higher in the number of leaves per plant; length, diameter and weight of root, and fresh plant weight, while the opposite was noticed in terms of the length of the leaves and the marketable productivity. While the speed of germination and maturity were not affected with the plant density. In terms of the interaction between the date and the density, the plants that were sown on the first date at low density achieved the highest germination velocity; maturity; length, diameter and weight of root; number of leaves per plant and fresh plant weight (10 days, 118 days, 23.1 cm, 31.33 mm, 136 g, 15 leaves/plant, 158 g/plant, respectively), while the highest leaf length and marketable productivity (28 cm, 5.71 kg/m2 respectively) were achieved at the first date and high density.
