VILLALVA-MORALES, Alejandro et al. Chemical and organic nutrition in Hass avocado in Filo de Caballos, Guerrero, Mexico. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.spe11, pp.2169-2176. ISSN 2007-0934. https://doi.org/10.29312/remexca.v0i11.794.
The study was conducted in the village of Filo de Caballos, municipality of Leonardo Bravo, Guerrero, Mexico, from November 2011 to October 2012, in an orchard of Hass avocado, 5 years old. The objective was to evaluate the treatment of chemical and organic nutrition of avocado trees; fertilizers used were: 50 kg tree of cattle dung (manure); 200-100-200 kg ha-1 of N-P-K (edaphic) and 30-10-15.30 kg ha-1 of Ca-Mg-B (foliar). We found that in buds, treatment manure + edaphic + foliar (41 shoots/branch) was better than treatments manure + edaphic (19 shoots/branch), leaf (9 shoots/branch) and the control (21 shoots/branch). And with 17 fruits, manure + treatment + foliar edaphic significantly exceeded the edaphic + foliar treatments (6 fruits), leaf (1 fruit) and the control (3 fruits). The manure + foliar treatment had the highest length (16 cm) of the main shoot, beating the treatment of manure + edaphic (7 cm) and leaf (9 cm). The edaphic + foliar treatment (75 cm2) had higher leaf area than control (65 cm2) and had the highest fruit weight 2.62 kg with 10 fruits, which was significantly higher than the control (1.51 kg 10 fruits).
