Abstract

The research was carried out in Dahr Al-Qusair Region-Homs during three successive seasons 2015, 2016 and 2017 on Golden delicious trees, to demonstrate the effect of summer pruning on two different periods on the productivity of pruning trees in the next season, and on qualities of fruits. The results showed that the last ten days of July had insignificant differences compared with other dates in increasing the production of trees. The average of production reached 61.67 kg in the first season and 70 kg in the next season. The results showed also, that there were insignificant differences between the three dates in their impact on firmness and TSS of fruits.

Abstract

A field experiment was conducted during summer season 2013 at AL-Anbar Governorate to study the response of peanut (Arachis hypogea L.) to different concentrations and types of boron under deficit irrigation conditions. A split-split plot design was laid out in three replications. Three concentrations of boron (0، 150، and 300) mg/l were sprayed. The experiment also included three levels of irrigation (50, 75 and 100) % of depth of irrigation. The results showed that the concentration of 150 mg/l of sprayed boron caused an increase in dry root and plant weight, pod yield and dressing ratio (12.50 g/plant, 380.96 g/plant,320.08  g/plant, %74.9 and 1.170 Kg/m3 respectively. The level of 75% of depth of irrigation gave best indicators for both dry root and plant weight, pod yield and dressing ratio (48.17 cm, 14.83 g/plant, 452.23 g/plant, 357.25 g/plant and 87.6% respectively. The results also showed that the effect of triple interaction between types and concentrations of boron and levels of irrigation was insignificant for most of the traits except dry plant weight.

Abstract

This research was conducted to determine the effect of covering rows with two types of transparent and black polyethylene on the growth and productivity of two genotypes of eggplant (Alwardi and Black) under the conditions of Bseren, Hama government, Syria during 2014 season. Split plots design was used in this experiment, with three replications. The results showed that covering rows with polyethylene has a positive effect on the vegetative growth of eggplant in comparison with the control. This was reflected positively on production and early maturity. Eggplants genotypes that were covered with transparent polyethylene exceeded significantly the other eggplants genotypes that were covered with black polyethylene in all the studied traits. The early maturity was clear for covering plants with both transparent and black polyethylene slices in comparison to the control during the first month of picking up fruits. Both treatments of covering exceeded the control in terms of productivity by 46.14% and 20.41%, respectively.

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.

Abstract

The present investigation was carried out at Latakia Agricultural Research Center, during (2011-2013), to study the propagation of male kiwi trees by wooden cuttings at two collecting dates (January and February). NAA and IBA regulators were applied at two concentrations (5000, 6000 ppm). In addition, of four treatments of the mixture of both regulators. The cuttings were planted within a glasshouse for 60 days under sprinkle irrigation conditions in order to study the effect of some factors (collecting date, location of cuttings on shoot, type of regulator and its concentrations) on some characters of cuttings (rooting ratio%, weight and size of roots, and weight and size of shoots. The results showed that the first collecting date (January) was significantly better in terms of weight and number of roots and shoots and rooted cuttings number. The rooting ratio was 64.9%, 54.3% respectively. According to cutting location on the shoot, the middle and basal cuttings were exceeded significantly the typical one in term of roots weight (20.31, 19.81, 15.55 g respectively) and also according to root size (20.55, 20.06, 15.57 cm3 respectively). The NAA and IBA regulators; had different effects, where the regulator (NAA) was significantly superior to the regulator (IBA) and the mixture treatments in terms of the average number of roots / cuttings. While the shoot weight and size were higher at IBA and mixture treatments than NAA. The mixture treatment 3000 ppm of (IBA + NAA) gave high values of roots weight and size. The treatment of 1500 ppm of mixture (IBA+ NAA) was significantly superior compared to the other treatments in terms of the number of rooted cuttings (75%) comparing to the control (28%).
