Abstract
The use of rootstocks in fruit production is extremely important, as well as reducing juvenility also enables faster production. In this context, the objective was to evaluate the effect of different rates of manure and application of organic fertilizer on the growth of guava rootstocks. The experiment was conducted in the greenhouse of the State University of Paraiba (UEPB) in municipality of Catole do Rocha-PB, Brazil. The experimental design was completely randomized (CRD), with in factorial 5 × 2, with 6 repetitions. The treatments consisted of the combination of manure proportions: (0, 20, 40, 60 and 80% v/v) mixture to the ground (2: 1 v v-1) and the second factor consisted of organic fertilizer application (with and without). 30, 60, 90 and 120 days after sowing (DAS) evaluated the following variables: plant height, leaf number, stem diameter, leaf area, root length, absolute growth rate and relative plant height , stem diameter and leaf area, dry matter of root mass, shoot dry matter mass, the total dry matter and Dickson quality index. The use of cattle manure at the rate of 80% positively influenced the growth of guava rootstocks with the application of organic fertilizer. Key words: Psidium guajava L., substrate, organic agriculture.
Highlights
In Brazilian Fruits there are several fruit of enormous economic importance, among them stands out the guava (Psidium guajava L.), a plant native to tropical America, which is distributed naturally throughout Brazil, with great economic importance because of the flavor nice, high nutritional value and great market acceptance, since its fruits are eaten both in natura as processed form (Oliveira et al, 2015)

For the isolated effect of cattle manure, it was observed that the plant height, leaf number showed significant effects at 30, 90 and 120 DAS, to stem diameter in all periods and leaf area at 90 and 120 DAS
