| Descripción: | Rice is one of the most widely produced crops worldwide, the development of technological service packs that help to increase its sustainability leads to positive impacts on economies and environments at a global level. The objective of this experiment was to demonstrate the efficiency in the productivity of drip fertigation system in the Conarroz 3 variety. The materials and methods used were two plots of 1000 m2 each, where different nutritional levels were applied, the irrigation hoses had drippers (40 cm spacing) with flow of 1 l·h-1, spaced every 1 m between them. The experiment was run in two production cycles to analyze the climate impact on production. The Results has shown with nutritional doses applied to 100% of its requirement, with fertigation it was possible to produce 6.1 to 6.5 Ton·ha-1 with a water yield of 8-7 kg·ha-1·mm-1 irrigated, the productivity exceeded in more than 15%, comparing to what could be obtained in a Control with conventionally fertilization applied to the soil. A response of the variety to climatic variation was observed, where the production window from May to September showed better yields results, it was produced by higher radiations and temperatures during the test. Conclusion: it is possible to increase production via fertigation in the Conarroz 3 variety and thus introduce drip irrigation in rice as an instrument to increase yields. |
