Efeito de diferentes doses de adubação nitrogenada na produtividade da cultura de trigo

Abstract

Wheat (Triticum aestivum L.) occupies the first place in world production volume, and has application in a wide range of products. By virtue of to its importance in the market and also to its wide applicability, in order to improve certain branches of activity, such as nutrition and health, research and development of new products and science and technology. Wheat is the raw material for the preparation of daily consumed foods. The objective of this project was to evaluate the yield in wheat crop using the cultivars Tbio Toruk and Tbio Mestre, in different doses of nitrogen fertilizing (0, 50, 100, 150 kg ha-1 of N).The experiment was carried out in Marialva (PR) where the cultivated soil is characterized with dystrophic Red Latosol. The cultivation was done by the no-tillage method in succession of soybean crop. The work was carried out in a randomized 4x4 block design, with three replications for each fertilizing, randomly distributed, and using as fertilization the fertilizer NPK+ 14-18-18-6S-1B2O3. The ideal dosages for crop production were evaluated, with the analysis of variance, 1000 grain test, yield (kg/ha) and stem length of the plants obtained. With the results and analyses performed, it is observed that the tbio toruk variety did not present statistical differences to the productive parameters analyzed, the tbio mestre variety showed a productive a growing until the third treatment (100 kg /ha), the top dosage showed a fall in the productive yield of that variety.
