EFEITO RESIDUAL DE MODOS DE APLICAÇÃO DE ZINCO NA NUTRIÇÃO E NO CRESCIMENTO INICIAL DA CULTURA DO ARROZ

Abstract

In systems of high production the micronutrients, especially the zinc is important for the culture of the rice. The present work objectified to evaluate the residual effect in ways of application of Zn on the nutrition and the initial growth of rice plants. The experiment was in a completely randomized design, with four treatments, having had zinc applied by foliar, incorporated in the ground and the seeds and the witness (without zinc), in four repetitions. To the 42 after the emergency, evaluated the text of Zn in the ground and the plant and the initial growth of the rice plants. The application of Zn saw ground incorporated provided residual effect in the text of the micronutrient in the soil. The application of Zn saw foliar promoted greater absorption of the nutrient for the rice plants. The ways of application of Zn saw seed, foliar and ground had been similar in promoting the increment in the production of dry matter of rice plants.
