Phenotypic and genetic performance of Arabica coffee seedling due to effect of genotype and urea

Abstract Growth and production of arabica coffee are affected by seedling quality which is depends on genotype maintenance such as fertilizer Urea. Th objective this research was to examine the effect Urea phenotypic genetic performance seedlings. The experiment done at greenhouse Agriculture Faculty Nommensen HKBP University in Medan. Seven Arabica genotypes from seven garden Subdistrict Dolok Sanggul four level were used. Plant height, stem diameter, leaf number, area, its ratio observed. result revealed that significant interaction number diameter proves certain dosage will give higest performance. Heritabilites coefficient, advance genetic, genotypic coefficient variations low. Phenotypic low, moderate high. Phenotypes ratios correlated highly significant.
