SUMMARY
In Granja Zahorí, Cuyotenango, Suchitepéquez, the experiment was carried out
on Capsicum annuum L chile bell pepper, taking into account that Marli R and
Nathalie f1 hybrids are recommended for this zone. In addition, to improve yield and
fruit quality, the application of AG3 gibberellins is recommended, so the following
doses were used: 0 gr/ha, 2 gr/ha and 4 gr/ha, with the purpose of induction and fruit
setting, being reflected in the yield and final quality of the product. A randomized
complete block design was used, with a split plot arrangement, due to field
conditions, with 12 treatments and four replications, for a total of 48 experimental
units.
According to the analysis of variance, the use of gibberellic acid did not influence
any of the response variables evaluated, since there was no significant difference in
this factor. As for the use of two hybrids, it was determined through the analysis of
variance that in this factor there is a significant difference, being the hybrid Marlie R
significantly better than the hybrid Nathalie F1, on the evaluated response variables
yield in kg/ha (8844.09 Kg/ha), fruit growth length (111.46 mm) and fruits per plant
(7 fruits per plant on average).
According to the economic analysis on production costs of each treatment, T2
(Marlie R hybrid and 0 gr of AG3) is the most profitable of all treatments with a
profitability index of 43.91% and a total production profit of Q 20,507.02 per hectare
in relation to the total production cost of Q 45,108.55/ha.
It is necessary to use fungicides for the establishment of chili peppers in the open
air, due to the fact that from September to October in this zone there is constant
rainfall, which provides a suitable environment for the proliferation of fungi and
diseases. |
