LOW-COST AUTOMATIC IRRIGATION IN FAMILY FARMING

The objective of the work was to evaluate different methods of irrigation management in the development of the plant and productivity of cucumber (Cucumis sativus) culture in the conditions of Parauapebas - PA. The experiment was conducted in a greenhouse, with 4 treatments (a traditional treatment with fixed amount of water per day [1], an Irrigas sensor-assisted treatment [1], an Arduino-controlled treatment with one daily irrigation [3] and an Arduino-controlled treatment with two daily irrigations [4]). An entirely randomized design with 6 repetitions per treatment was adopted. The following variables were evaluated: number of fruits, total weight harvested per plant and plant height and, from these, the productivity. There was no significant difference (P<0.05) in any of the variables and, with the exception of plant height, all had normal distributions.
