Abstract

This research was carried out at Barry Al- Garby village, Al Salameah region during 2017/2018 season to study the effect of spraying with yeast suspension and plant density on some growth and productivity traits of faba bean crop (var. Kubrusy). Three concentrations of yeast solution were used (2, 4 and 6) g/l in addition the control treatment. Three densities were studied (12.5, 16.7 and 25 plants/m2). A split plot design with three replications was used. Spraying with yeast suspension (6) g/l caused a significant increase in plant height (75.21) cm, number of branches/plant (3.65), pod length (11.33) cm, number of pods (11.18) pod/plant, weight of dry seeds (33.37) g/plant and seed yield (0.58) kg/m2. Increasing plant density to (25) plant/m2 caused an increase in plant height (75.2) cm, the first pod height (18.57) cm and seed yield (0.53) kg/m2, while it caused a significant decrease in number of branches/plant (2.97), number of pods(6.5) pod/plant , weight of dry seeds (21.12) g/plant. Spraying (6) g/l of yeast and planting (25) plants/m2 gave the highest seed yield (0.69) kg/m2.

Abstract

The research was carried out in the coastal area at Bauqa Farm, and at the laboratories of Faculty of Agriculture, Tishreen University, during the season 2018 in order to study the effect of plant density and nitrogen fertilization and their interaction on some morphological, physiological and productivity parameters of sorghum plant to obtain the highest grain yield. Jumbo variety  was used which obtained from General Organization of Seed Multiplication in Latakia. The design of the experiment was Randomized Completely Block Design (RCBD) with the arrangement of split plot design with three replicates. The density treatments were distributed in the main plots (3.33, 5 and 10 plants/m2), while nitrogen fertilization levels were allocated in the sub plots (200, 300 and 400 kg/ha) in addition to the control treatment without nitrogen addition. The density of 10 plants / m2 and the  nitrogen fertilization of 300 kg/ha gave the highest grain yield (ton/ha) under the conditions of the experiment. While the density of 3.33 plants/m 2 and the nitrogen addition of 400 kg/ha gave the  highest length of the plant number of leaves/plant, number of grains/rosset and weight of 100 seeds. The grain yield correlated positively and significantly with rosset length (r=0.541**), grains number (r=0.509**),  area index (r=0.502 **) and the rosset weight (r=0.456 **). Thus it is possible to improve the productivity by improving the mentioned traits above due to the positive correlation with them.

Abstract

The research was carried out during 2017/2018 growing season at Buqa Farm, Faculty of Agricultural Engineering, Tishreen University in Lattakia, to study the effect of plant density and infection with mosaic cucumber virus on the productivity of beans (Vicia faba L.). The local bean variety was used with three plant densities (5, 10 and 20 plants/m2). Virus infection was made when the length of the plant reached 15 cm. The design of the experiment was carried out according to the Randomized Complete Block Design (RCBD) with the arrange of split plot with three replicates. The treatments of infection were distributed to the main plots while the sub plots included the density treatments. Results showed that the plant density of (5 plants/m 2) surpassed the plant densities of (10, 20 plants/m2) in number of branches per plant and fresh green weight of the plant at pods formation stage and the number of pods per plant. The plant density of (20 Plants/m 2) surpassed the other densities (5 and10 plants/m2) in seed yield and weight of 100 seeds, and the height of the plant. The infected plants (E0) when planted at high density (20 plant/m2) had the highest seed yield and weight of 100 seeds. The infection with mosaic virus did not affect the height of the plant, and the healthy plants (E1) were superior to infected plants (E0) in all studied traits (The plant height had declined by 10.23- 12.17% and fresh green weigh for each plant by 0.76- 1.77% and the number of pods per plant had declined by 14.08- 31.76 % and  the seed yield by 13.80 – 19.84 % and weight of 100 seeds by 1.77-5.50 % in the infected plants by mosaic cucumber virus compared to the healthy plants )

Abstract

This study was carried out in the Syrian coastal in Tartous governorate, during the growing season 2014, to study the effect of four plant densities (10.00, 13.33, 20.00, and 33.33) plant/m 2, and three levels of phosphate fertilizations (107.2, 160.8, 214.4 kg/ha of super phosphate P2O5 46%), besides the control, on quality traits (nitrogen, crude protein, phosphorus and potassium) of the coriander plant. The experiment was designed in a Randomized Complete Block design (RCBD) with a split plot arrangement of treatments with three replications for each treatment. The results revealed significant differences between treatments for most of studied traits, in addition to an interaction effect between plant density and fertilization. Although, the densities (10, 13.33 .20 plant /m 2) varied in their effect, but it significantly outperformed the highest density (33.33 plant/m2). The treatment 10 plants/m2 was more importance in terms of increasing the plant content of N, P, K. On the other hand, most of the measured characters were increased as a result of the increasing rates of phosphate fertilization. The treatment (160.8 kg/ha of P2O5) had a significant superiority upon on the rest of the treatments in terms of its effect on phosphor, nitrogen and crude protein, whereas the treatment )214.4 kg/ha (increased each of the content of the seeds of both of nitrogen and phosphor. The interaction effect between the highest plant density (33.33/m2) and the highest level of phosphor fertilization (214.4 kg/ha) had the superiority upon the other treatments in term of increasing each of seed content of P, N, protein, and K content of vegetative growth.
