Rendimiento y eficiencia en el uso del agua de un genotipo de chile serrano (Capsicum annuum L.) Producido bajo fertilización orgánica e inorgánica en casa sombra

The objective of this research was to evaluate the effect of organic fertilization, compared to inorganic and a combination of both in the cultivation of serrano pepper (Capsicum annuum L.) under shade net at the University of Sonora. The variables that were evaluated were: fruit weight, yield, length and diameter of fruit, as well as efficiency of water use. For the weight of the fruit per plant, no significant differences were observed between treatments in the first two cuts, however, for the third cut if there were significant differences, the best treatments were inorganic fertilization and the mixture of inorganic plus algae extracts with 280.29 and 212.21 g respectively. For the fourth and fifth cut the trend was in the same way up to the final average resulting in the best treatment inorganic fertilization with 233.94 g per plant followed by the mixture of inorganic plus seaweed extract with 166.75 g per plant. Regarding the yield, it can be observed that from the third cut the treatments that contained inorganic resulted with the highest yield, resulting in the total average inorganic fertilization with 38665.77 kg ha-1 and inorganic fertilization plus algae extract with 27514.08 kg ha-1. The results obtained from this research show that organic fertilization does not provide high yields compared to inorganic because of the gradual release of nutrients to the plant.
