Abstract

The research was carried out during the agricultural seasons of 2017 and 2018 at a private farm in Deir Al-Zour on watermelon plants (Citrullus lanatus L.) Niagara variety to study the effect of using different concentrations of Huzone nutrients (0, 2, 4 and 6 cm3/L per plant), at a rate of three sprays, the first spray was accompanied at the stage of 2nd  leaf formation, and the second was at the beginning of fruit stage formation, while the third spray was  two weeks before fruits maturity. The pruning methods were (Method A: Pruning the plants to three stems while keeping one fruit on each stem, the second method B: Pruning the plants to four stems while keeping the one fruit on each stem, and the third method was pruning the plant to five stems and keeping one fruit on each stem, besides the control (without pruning). Randomized Complete Block Design RCBD was used with three replicates per treatment. The results showed that there was a significant effect of pruning and Huzone nutrient on all studied traits. The control (without pruning) which treated with a concentration of 4 cm3/L achieved the highest value in the number of leaves, and reached 231-234 leaves/plants for the first and second seasons respectively. The highest value of the leaf area when using the pruning method on three branches and spraying with a concentration of (4 cm3/L) gave a value of (3131-3120 cm2) for the first and second seasons respectively. The interaction between spray and pruning significantly affected the number of days to flowering, where this trait decreased when using 4 cm3/L of Huzone with the pruning method on three branches compared to the other treatments. The number of male flowers decreased in the plants which pruned on three branches and sprayed with a concentration of 4  cm3/L of Huzone, where the number of male flowers was (18.4-20.9 flower/ plant) for the first and second seasons respectively compared to the control and other concentrations. In terms of the number of female flowers, it increased at pruning on three branches and by adding a concentration of 4 cm 3/L (13.93-15.2) compared with the control and other concentrations.

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.
