| Abstract | ||
| Organic fertilizers play a significant role in organic systems and sustainable soil management. In general, organic fertilizers increase soil fertilization and can reduce the negative effects of the excessive use of chemical fertilizers and synthetic man-made fertilizers. This study designed aimed to check the comparable effect between Organic and chemical fertilizer NPK on growth traits of Dedonia viscosa. the experiment conducted in Agriculture college forestry department in plastic house during October to April 2024. RCBD full factorial used to conduct the treatment, 10 replication per treatment with three fertilizers Organic humic acid, NPK chemical and control .in April the seedlings harvested, the biometric traits height and diameter measured in seedlings and biomass trait. The results show highly significancy about effect of plastic house conditions temperature and light on biometric growth of seedlings were p value ≤0.001 between D1 and D2 during the 6 months of experiment with increment 53 cm in height of seedling. And the results show significance between fertilizers effect on biometric and biomass growth traits (shoot biomass and root biomass) and seedling diameter if the p value were p value ≤0.05.so the data p value for the growth trait (Shoot biomass) for the seedlings showed significant P value ≤0.05 and ≤0.001 during the experiment duration between NPK and Humic acid and control. and the p value of anova table were ≥0.05 between NPK and Control and ≤0.001 between Control and humic acid. Cording to these results we recommend to propagate dedonia viscosa inside the plastic house to keep him from winter low temperature and wind outside and even we recommend to use organic humic acid fertilizer 10ml/ltr conc, even the NPK chemical can be used in 800 ppm conc and it give good results but less than humic acid which is get better growth traits biomet | ||
