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

A field experiment was conducted at Hama Research Station, General Commission for Scientific Agriculture Research (GCSAR), during 2016/2017 and 2017/2018 seasons, to compare production, quality and morphological characteristics of monogerm fodder beet variety, i.e. Jamon under four levels of nitrogen fertilizer (20, 80, 120 and 180 pure units of N, urea 46%/ha). The experiment was sown in summer during September. A randomized complete block design (RCBD) was used with three replications. The statistical analysis of both seasons exhibited a significant effect of the nitrogen fertilizer (N) on all of the production traits (shoot yield (ton/ha)) and morphological traits (shoot weight per plant (g), and root length and diameter (cm)). Also, there were no significant differences in quality traits (dry matter in root and shoot (%) and sucrose (%)). The least significant difference test (LDS0.05) showed the possibility of adding 80 pure units of Urea/ha to get the best production, quality and morphological traits.

Key words: Fodder beet, Nitrogen fertilizer, Production traits, Quality traits, Morphological traits.

Abstract

The field experiment was conducted at Al Mray’eyh Research Station, Scientific Agricultural Research Center of Der- Al Zur (NE Syria) during 2009/2010 and 2010/2011 seasons, to study the effect of two methods of irrigation (sprinkler, furrow) and five levels of nitrogen fertilizers (0, 60, 120, 180 and 240), on technological and production traits of three sugar beet varieties, i.e. Dita, Reda, and Nadir in summer time. The experiment was sown in August. A split split plot design was used with four replications. The results exhibited that the addition of 180 pure unit of nitrogen achieved the best technological and production traits. Dita monogerm variety surpassed the other varieties in most of the technological and production characters. It is recommended the sprinkler irrigation, because it increased sucrose percentage (16.2%) and root yield (73.7 ton/ha), as compared with furrow irrigation (15.9%, 67.2 ton/ha) respectively, besides sprinkler irrigation saves water consumption about 20% as compared with furrow irrigation method.
