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.

Abstract

This study was carried out at Deir- El Hager Research Station, Damascus countryside, General Commission for Scientific Agricultural Research, Syria, during 2012 to estimate the microbial content in the milk of Shami Camels, and determine its quality and possible risks resulting from drinking milk as it is. Twenty-eight milk samples were collected from seven camels that seem to be apparently healthy. Laboratories tests were conducted in order to determine the PH of milk at fridge temperature (5 ± 2 °C), and room temperature (20 ±2 °C) for consecutive four days. The average of body cells number by microscopic method were estimated. It was found that there are limited changes in PH degree during storage period whether it is in fridge or in a room conditions. The minimum value of PH in fridge was 5.2 and the maximum value was 6.4. While minimum value of PH was 5.2 in room condition, and the maximum value was 6.2. T-test for double samples, showed that T value was 1.337, which means that there were no significant differences. The average of body cells in the samples that gave negative results using California Test accounted (2.2× 104 – 2.2× 105) cells/ml milk, and (8.6× 104 – 2.4× 105) cells/ml for positive samples. Besides all samples on Mac Conkey media gave a negative result, and no growth plantation of any bacteria was appeared. Whereas the relation between Staphylococcus growth phenomenon blood agar media plantation and the method of conservation at different temperature degrees found that the numerous number of infection with Staphylococcus was in the samples conserved in room temperature, where Square Chi value accounted 42.357 at less than 0.01 level of probability. The results assured not to drink camel milk without pasteurization, because of Staphylococcus germs that existent in the milk cause different human diseases.
