摘要: Despite the vine adaptation to different soil types, most are found in soils with low nutrient supply, requiring corrections. The organic fertilizer facilitates absorption of nutrients and improve structure. objective was evaluate effect fertilization bovine ovine manure on growth totalchlorophyll content ‘Merlot’ vines grafted three rootstocks. experiment conducted by Nucleus Study, Research Extension Oenology (NEPE2 ) variety VCR1 clone. treatments were applied rootstock ‘161.49’ 420-A ‘and’ Paulsen 1103’, used origin, totaling 12 treatments. Were evaluated plant height (cm) total chlorophyll (Falker clorofiLOG® ). at ‘Paulsen 1103’ showed greater clone VCR1, followed ‘420A’. But less leaves compared other Preliminarily itwas concluded that use manurefrom origin rootstocks ‘420A’ ‘161.49’, present higher content.
