Produção de trigo no sul do RS com diferentes fontes de nitrogênio associadas ao silício

Abstract

The present work aims to evaluate the effects of three different sources of nitrogen on the components of wheat production and productivity, applied in the furrow and in coverage. As a way of just complementing the work, we also use two different sources of Si. We want to see which is the best source of Nitrogen from a productive and economic point of view to maximize results and be able to produce quality seeds. Nitrogen is intended to nourish the plant and ensure that it has stronger and more sustainable development. It is an essential component of proteins, acid. nucleic acids, chlorophyll and many other secondary metabolites, therefore, it is required as a macronutrient in plant growth. Nitrogen is the nutrient absorbed in greatest quantities by plants, acting in photosynthesis and the formation of proteins in seeds. The main sources of nitrogen are Urea, Ammonium Nitrate and Ammonium Sulfate. In wheat, nitrogen is closely related to production potential, that is, research has proven that investment in nitrogen fertilization can result in greater yields in seed production. Excess nitrogen can cause some problems for plants as it is directly related to protein synthesis and growth. Plants present abnormal growth, with accumulation of green mass and probable etiolation. The use of Silicon together with nitrogen sources is due to work that proves that Si can be beneficial for N as a better use of the N supplied to plants. The results leave us with the certainty that nitrogen fertilization with Silicon can obtain excellent results and enhance the nitrogen applied.
