تأثير إضافة مستويات مختلفة من بعض أنواع الأسمدة (العضوية و الحيوية) في بعض الخصائص الفينولوجية و المورفولوجية لمحصول فول الصويا (Glycine max L.)

Abstract

The study was carried out in Sheikh Badr area, the village of (Al-Bathaniya) of Tartous Governorate for the agricultural season 2023, to study the effect of adding different levels of biochar and cow manure on the growth and productivity of soybeans (Glycine max L.)  The experiment was designed on the basis of complete random sectors with a witness and eight treatments (15 tons/ha-30 t/ha) of cow manure, (2% - 4% of soil by weight) biocharcoal, (15 tons/ha of cow manure with 2% of soil by weight of biochar) (15 tons/ha cow dung with 4% soil by weight of biochar) (30 tonnes/ha of cow dung with 2% soil and biochar weight) (30 tonnes/ha of cow dung with 4% soil and biochar weight). With three replicates per treatment, the study included many phenological crop characteristics such as the number of days up to (full germination, flowering, physiological maturity and full maturity), and morphological such as (average plant height at maturity / cm, height of the first century on the plant / cm) where the results showed: Biochar treatment exceeds 4% of soil by weight and cow manure 30 tons/ha in reducing the number of days required to The number of days required to start germination and for full germination, the height of the first century above the ground and the height of the plant compared to other parameters. The number of days from germination to flowering when cow manure was added decreased by 30 t/ha (3-9) days compared to other treatments. Thus, the addition of a combination of biochar and cow dung had remarkable positive effects on most of the studied qualities of the soybean crop.
