Production dynamics of Chile Morrón in response to genotype, pruning and density

Abstract

The present study was conducted with the main

objective of evaluating the yield and production

dynamics of Bell Pepper genotypes under shade

mesh based on population density and types of

pruning. A factorial experiment 2³ was established,

including genotypes, population densities and types

of pruning, in protected shade mesh culture and

fertigation. We used the experimental arrangement

of subdivided plots with four repetitions,

randomizing densities in main plot, subplot

genotypes and sub-subplot type pruning. The

culture cycle was 192 days, with nine cuts. It was

determined that the genotypes had a similar

behavior, appreciating good potential (41.981 t ha^-

¹). The high density increased the weight of fruits of

first and second quality with commercial value, in

addition to the total yield. Dutch pruning reduced

the production of waste fruits. In fruits of third

quality it was detected interaction Density x

Pruning, and in fruits of waste in Density x

Genotypes x Pruning. The production of waste fruits

(9.915 t ha^-1) consisted of deformed fruits (71.2%),

damaged by the sun (18.5%) and pests (10.3%).
