Physiological evaluation of the culture of sunflower (Helianthus annuus) with the use of NPK fertilizer and water restriction

Abstract

The aim of this study was to evaluate the germination potential of sunflower seeds to be used in the experiment and verify the vegetative development of culture in place, along with the use of NPK fertilizer with the elements in quantities of 20-20- 20. The experiment was conducted by a group of students of the discipline of Physiology of plants grown, of course a Bachelor's degree in agronomy. All activities such as Assembly and operation were carried out in the experimental area of the State University of Mato Grosso (UNEMAT), University Campus Eugenio Carlos Stieler, located in Macomb-Mt. The obtained results demonstrated that the use of formulation (+ fertilizer + water) was the most represented a momentary growth, characterized as the best combination. At the construction site, the availability of composted nutrients was greater for plants, thus providing greater development in their physiological processes in relation to the plants of the construction site without fertilization. However, recognises that the combination made by (+ fertilizer-water) also proved to be representative, once your evolution was considerable taking the days of observation. Therefore, of all combinations made, experimentation which proved less efficient was the dosage application (- compost + water), showing lower income growth.
