Influencia de vermicompost en el rendimiento de Vitis vinifera L. cv. Malbec en Ica, Perú

Abstract

The management of organic materials in vine ( Vitis vinífera L cv Malbec) is important when working with winter manure or cattle manure, which activates the surface rootless but this type of organic matter is restricted to use it in fields far from the sources of fruit processing therefore the we need to develop other organic matter sources with the same effects. For this reason this research evaluates the influence of hums from vermiscompost (V) elaborated by Eisenia foetida on the productive yields of vine on sandy soils (Aridisol) in Ica, Peru. The experiment used a randomized complete block design (DBCA) with four replications and four treatment base on the doses of V and they were T1 which is the control with no V; T2 is 1.5 t ha –1 of V; T3 is 2.5 t ha –1 of V and T4 is 3.5 t ha –1 of V. For the analysis of variance (ANOVA) SAS statistical software was use. The results obtained did not show statistical differences between the average production but there was a tendency to increase production with applications of 2.5 t ha –1 with yields of 12807 kg ha –1 while the control with no V being the treatment with the lowest production. Pearson’s Correlation Coefficient analysis indicates that there is a moderate positive association (r = 0.5) and a relation with linear approximation between the quantitative variables. In conclusion, the result of the mathematical model resulting from the linear regression equation indicated that for each additional kg of vermicompost can be expected an increase of 1.43 kg of vine.
