Abstract

The present research was aimed to evaluate the effectiveness of attractants placed in craft traps to reduce the bit population (Hypothenemus hampei). Three different mixtures of attractants and control were used in craft traps (4 treatments, which represent the mixtures frequently used by Amazonian coffee growers), arranged in a completely random blocks design. The variable number adult coffee drill was analyzed, as well as the most economical and effective treatment in the capture of adult coffee bit. The data were processed by means of a variance analysis to determine the differences between treatments, and the Tukey media multiple comparison test, at the statistical significance of p<0.05. The results have confirmed that the use of craft traps is a good alternative for adult coffee bit control. The treatment that allowed a greater capture of the coffee bits was T1 (mixture of 2 liters of boiled water + 200 grams of ground coffee), this was also the treatment that had the lowest cost for the elaboration of the artisan trap ($ 14.30). Finally, T1 turned out to be the most effective treatment for adult coffee drill capture in Amazonian conditions of Ecuador.

Abstract

This research aimed to evaluate the agronomic effect of deficit sprinkler irrigation sin the cultivation of banana Cavendish Musa AAA cv. Williams in Ecuador. Four treatments were carried out with different irrigation levels: T1 (40% of ETc (evapotranspiration of the crop)), T2 (60% of ETc), T3 (80% of ETc), and T4 (100% of ETc), with a design of complete random blocks and three repetitions. The results showed that the crop exhibited better biophysical behavior when irrigated at 100% of ETc throughout the study period, with higher values in total leaves and root weight, while there were no significant differences for plant height, pseudostem diameter, and leaf emission. T1 achieved greater efficiency, managing with less volume to convert the same amount of matter in vegetative development. Finally, the cost of irrigation application during weeks 5 to 16 of the crop's age was higher in treatment T4 (100% of ETc) due to the larger volume of water used in the irrigation system. It is concluded that the use of controlled deficit irrigation helps save large amounts of water, which translates into savings for farmers and better water distribution due to the effects of climate change from the reduction of flow rates.
