Abstract 

The research was carried out at the Lattakia Research Center (Sianow) of General commission for Scientific Agricultural Research at Lattakia. during two growing seasons 2021-2022, to study. The effect of four planting dates (1April – 15 April – 1 May – 15May) on yield traits and related traits to borer of sweet corn (Faihaa 1). the experiment was designed according to the Completely Randomized Design (C. R.D) with three replications. The results of the statistical analysis showed that the second date was significantly to the rest of the dates in terms of early maturity and yield traits such as  ear length  and 100 kernel weight, with an increase percentage of (2.85%, 2.81%) respectively, on the rest of the  planting dates. The second date also excelled in traits related to resistance borer, such as stem diameter and the length of the internode basal ring (LIBR), with an increase rate of (0.61%, 0.31%) respectively, over the rest of the dates. It also had the lowest percentage of the percentage of dead hearts, intensity of damage and the percentage of lost at this the planting date, while there were no significant differences between the four dates, in number of holes, and the results showed that the second date (April 15) significant in the productivity traits and escape from infection by maize stalk borer Sesamia cretica, of sweet corn (Faihaa 1), in the Syrian coast’ conditions. The result of the correlation coefficient showed that there is significant positive relationship between grain yield and some yield components while foe the traits which related to borer, there is significant an inverse correlation between the grain yield t and LIBR. There is significant positive relationship between, grain yield and diameter stalk.

Abstract 

The research was carried out in Al-Drouqiat village, Lattakia Governorate, Lattakia University for the year 2023-2024 to study some qualitative characteristics of sesame plants and oil production under the influence of five levels of phosphate fertilization (0, 40, 60, 80, 100) kg of triple superphosphate fertilizer TSP containing 46% of phosphorus pentoxide P2O5, and four concentrations of zinc spraying (0, 30, 60, 90) mg of zinc sulfate fertilizer Zn2SO4. The experiment was conducted according to a randomized complete block design with a single split plot arrangement and three replicates. The main plots included phosphate fertilization, while the secondary plots included zinc spraying. The results showed that the phosphate fertilization level of 100 kg TSP 46% P2O5/ha significantly outperformed all other fertilization levels, and the control had the highest mean for the trait he percentage of oil (52.07%), protein (23.13%), and ash (3.80%) in the seeds, and the highest oil yield was recorded at the level of 100 kg P2O5/ha (653.46 kg/ha), while the control achieved the highest average for the characteristics of carbohydrate percentage (12.29%), moisture (7.17%), and fiber (15.48%). The zinc spray concentration of 60 mg Zn2SO4/L gave the highest average of oil percentage (49.36%), protein (22.11%), and ash (3.78%) in the seeds, while the concentration of 90 mg Zn2SO4/L gave the highest oil yield (514.80 kg/ha). In contrast, the control achieved the highest average of carbohydrate percentage (10.80%), moisture (7.25%), and fiber (13.08%) in the seeds. The interaction (100 kg TSP 46% P2O5/h × 60 mg Zn2SO4/L) achieved a significant superiority with the highest value for the oil percentage trait (53.76%), protein (24.05%), and ash (3.90%) over all other interactions. The interaction (100 kg TSP 46% P2O5/h × 90 mg Zn2SO4/L) gave the highest value for the oil yield trait (715.55 kg/h), and there were no significant differences between it and the interaction (100 kg TSP 46% P2O5/h × 60 mg Zn2SO4/L) regarding the oil yield trait.
