Incidencia de dos acaricidas de síntesis química en los agentes polinizadores en el cultivo de fresa (Fragaria ananassa D.) cultivar Albión en el cantón Riobamba, provincia de Chimborazo.

Abstract

The present investigation proposes: to evaluate the adaptation and yield of eight pepper varieties (Capsicum annuum L) in the greenhouse, Riobamba canton, Chimborazo province: a randomized complete block design with eight varieties and three repetitions were used; the varieties were: KAIMAN, 14PE9581. RED MADONA, ITAMARA F1, CLXPHSA4 F1, ALAZAN, CANARY, MARTHA. These varieties according to characteristics were a hybrid vigour. Parameters were evaluated such as: percentage of germination percentage of yield, height of the plant at 30, 60, 90 and 120 days respectively, diameter of the stem at 30, 60, 90 and 120 days respectively, number of fruits at harvest, length of the fruit, diameter of the fruit, weight of the fruit harvested, days to harvest, yield per treatment and hectare, temperature, relative humidity and cost-benefit ratio. In all the treatments under study 100% of the yield was obtained, however, the best results for most of the other parameters evaluated in all the dates of evaluation were the varieties: 14PE9581 with a yield per hectare of 16.4 fruits per plant and CLXPHSA4 F1 with a yield per hectare of 13.13 fruits per plant. The variety that presented the highest Profit / Cost was 14PE9581 with a profit of $ 1.48. While the variety with the lowest Profit / Cost was ALAZAN with a loss of 0.20 dollars. Therefore, from the agronomic and economic point of view of pepper under greenhouse, recommends planting the variety 14PE9581 for presenting the best adaptation and profitability. In addition, conduct research based on fertilization in this variety to determine the maximum potential of this variety. Keywords: HORTICOLA YIELD- HYBRID VIGOR - GREENHOUSE CROPS - PEPPER VARIETIES
