Abstract

Fodder beet is a high production crop, and is a very promising crop to be grown in Syria, and attention has grown to the cultivation of this crop. However, recommended agronomic practices for maximizing productivity are limited. A field experiment was conducted in season 2017/2018 to study the effect of planting date and varieties interaction on the production, and some qualitative and morphological traits of five fodder beet cultivars (Caribou, Varians, SV Four 16, Tarine and Lipari). The experiment was a randomized complete block design (RCBD) in split plots arrangement with three replicates, planting dates (mid Feb. and mid Mar.) were assigned to the main plots and fodder beet cultivars were allotted to the sub plots. The results of the statistical analysis exhibited the superiority of mid Feb. date as compared with mid-March for all the studied traits. Varieties exhibited highly significant (p≤0.05) differences in most of the studied characteristics except plant number per hectare. Lipari and Tarine surpassed the other varieties in terms of the production, morphology and qualitative traits. The conclusion is to plant fodder beet in mid-February time in Homs, Syria, to attain the highest yield, and quality traits of fodder beet crop. Also, the study recommends further trials identify optimum agronomic practices especially harvesting date, fertilization and spacing in the other sites in Syria.

Key words: Planting date, Fodder beet, Production, Morphological and qualitative traits.

Abstract

The study was carried out in Mokhtaria Research Station, Homs Agricultural Research Center, General Commission for Scientific Agricultural Research Center, Homs, Syria, during 2008-2009 and 2009-2010 seasons. Two methods of drip irrigation were applied (mulched, without mulch) on tomato crop to be compared with the traditional method (surface irrigation). The results showed that the average of the total water consumption for the drip irrigation (mulched) was 3345 m3/ha and percentage of saving water irrigation was 55% as compared with control (traditional surface irrigation), while the average of the total water consumption for the drip irrigation (without mulch) was 3785 m3/ha and percentage of the saving water irrigation was 49% as compared with control, although the average of the total water consumption for the traditional surface irrigation was 7426 m3/ha. In terms of farming method (traditional and organic) the production under drip irrigation (mulched) were 29.7 and 38.4 ton/ha, with an increment in yield of (60 and 68%) as compared with the control (surface irrigation) which were 18.6 and 22.9 ton/ha (traditional and organic), respectively. On the other hand the production under drip irrigation (without mulch), in terms of farming method (traditional and organic) were 38.4 and 45.1ton/ha with an increase in yield 106 and 97%, respectively as compared with the control.

Abstract

The study was carried out during 2011-2012 at Ciano citrus experimental station. Growth and yield of 22 years old orange trees (Washington Navel 141) budded on seven citrus rootstocks (Sour orange, Troyer citrange, Carrizo citrange, Citrumelo 4475, Citrumelo 1452, Macrophylla and Cleopatra mandarin) have been studied. The results showed that Sour orange gave the highest yield (79 kg/tree). Citrumelo 4475 significantly showed the highest trunk section area of the rootstock (779.88 cm2); the highest percentage of fruit juice was achieved by Citrumelo 4475 and Troyer citrange (43.43%, 42.37%) respectively, which were significantly superior to Cleopatra (37.39%). The highest percentage of total soluble solids was achieved by Cleopatra (13.1 %), while the highest TA% achieved by Citrumelo 4475 (0.88%) without significant differences compared to other treatments.
