Abstract
This study was conducted in Iraq / Baghdad Al-Yusufiya for the season 2019 to study the effect of spraying with Nutrition Solution and organic Fertilizer in some vegetative growth characteristics of peach seedlings. The nutrient spray (F) was used with four concentrations (F0) 0, (F1) 1.5, (F2) 3, (F3) 4.5ml.l−1 and organic fertilizer spraying (B) with four concentrations (B0) 0, (B1) 3, (B2) 4, (B3) 5 ml.l−1. The results showed that F3 recorded the higher value of plant height, leaves area, chlorophyll content, nitrogen(%), phosphorus(%), potassium(%), and carbohydrate, nitrogen and C/N ratio which gave 34.86 cm, 3819 cm2, 256.4 mg.100g−1fresh weight, 1.73%, 0.53%, 2.74%, 2.73%, 28.34% and 10.35% respectively. likewise, spraying, treatment (B3) exceeded the rate of increase in plant height, leaves area, chlorophyll content, nitrogen(%), phosphorus(%), potassium(%), carbohydrates, nitrogen and C/N ratio was 32.06 cm, 34.10 cm2, 254.5 mg.100g−1fresh weight, 1.52%, 0.45%, 2.10%, 2.52%, 23.12% and 9.08% respectively. As for the interaction between the studied factors (F3B3) achieved the highest value in plant height leaves area chlorophyll content, nitrogen(%), phosphorus(%), potassium(%),carbohydrates and nitrogen which gave 37.31 cm, 43.72 cm2,277.4 mg.100g−1fresh weight, 1.87% 0.58%, 2.99%, 2.88% and 29.56% respectively.
