Abstract: 

The research was carried out in the Al-Zouba area of Tartous Governorate according to a completely randomized block design on whole plants of the two tobacco varieties: Burley and Virginia, during the 2022 agricultural season, to study the effect of irrigation with municipal fertilizer infusion on some morphological, physiological, qualitative and biochemical characteristics (relative water content) of the two studied varieties, which resulted in Treating the two cultivated varieties of tobacco with an infusion of local fertilizer resulted in a significant increase in all the studied traits compared to the control treatment. The results showed that the studied traits were most affected by treatment with the organic fertilizer infusion, which were leaf area, dry weight of leaves, leaf specific gravity, and photosynthesis efficiency. The two studied varieties responded in the same way to treatment with the organic fertilizer infusion, in all the studied traits, with the Virginia variety superior in all the studied traits. Except for the quality of water content, which was superior to the Burley variety (78.5%). Which shows the importance of adding local fertilizer to improve the growth of tobacco varieties, for example, and obtain the best production and highest quality.

Keywords: municipal compost, tobacco, representative efficiency, leaf specific weight.

Abstract: 

This research was conducted in 2022, in both its productive and molecular parts, the blood samples was taken from 70 laying hens of the Bovans White global hybrid layer and were subjected to DNA analysis, three genetic loci associated with egg production trait were studied (APH-09, APH-24, ADL-209). The egg-laying curve was studied for a period of 73 days, and the performance of the hybrid chickens was evaluated in terms of productivity. Eggs were weighed on a daily basis and for each individual separately in order to calculate the average weekly egg weight. The age of sexual maturity for the individual and for the flock separately was recorded. The number of eggs produced reached 73 Eggs in 13 individuals at the age of 31 weeks. The percentage of egg productivity reached 99.48% in the month of peak production, and the weekly average egg weight reached 54.28 grams in the 31st week of the birds’ life. The age of sexual maturity of the individual was recorded ranging from the age of 121 days at its minimum to 150 At its maximum, the age of sexual maturity of the flock was recorded at 145 days. the percentage of flock productivity reached 50% on two consecutive days. The molecular results showed the variation of individuals in the studied hybrid flock in terms of the absence or presence of alleles and in the total number of alleles found in each of them. The total number of alleles obtained on the three genetic loci was (18) alleles with an average of 5.666 alleles/one loci, while the genetic diversity values reached 0.248, 0.104, and 0.184 in the studied loci APH-09, APH-24, and ADL-209, respectively With an average of (0.178), this genetic diversity is a natural result in the Bovans White hybrid flock. The 18 chickens that showed alleles of the genetic loci studied were characterized by high productivity ranging from (0.84-1).
