Eficiencia de aplicación de tres métodos de riego en el cultivo de papa (Solanum tuberosum. L) en la estación experimental Tunshi.

Abstract

In the present investigation, the application efficiency of three gravity, drip and sprinkler irrigation methods in the potato crop Solanum tuberosum. L was determined by establishing a field trial with a randomized complete block design of three treatments with three repetitions in order to evaluate the application efficiency of the three irrigation methods based on the calculations of the distribution uniformity on the crop as well as biometric parameters in 10 plants per repetition every 15 days in relation to the duration of the crop production cycle. In addition, the plant water status and soil moisture content were monitored. At the end of crop production cycle, the total applied sheet and water footprint were determined, the level of efficiency of the treatments in the potato crop Solanum tuberosum. L was gotten by yield per plant, per category and per hectare. The results were drip 93%, sprinkler 85% and gravity 46%, with an irrigation requirement of 218 mm, 254 mm and 431 mm respectively. The drip yield was 28ton / ha, sprinkler 26 ton / ha and gravity 23 ton / ha; Regarding the biometric parameters, the number of leaves for drip was 160 leaves, sprinkler 158 leaves, and gravity 112 leaves; the height of the plant for sprinkler was 83.2 cm, drip 75.2 cm and the lowest height for the gravity treatment was 65.2 cm; the diameter of the stem was 14.5 mm in sprinkler, drip 14.2 mm and gravity 12.1 mm. In conclusion, the drip treatment is the most efficient with less water requirement and with high yields compared with the other treatments. It is recommended to carry out evaluations on stomatal conductance in relation to time and temperature adjusted to curves with frequent data.
