1. Nitrogen fertilization split in green corn under rainfed system
ABSTRACT The objective of this work was evaluating the nitrogen fertilization splitting on the performance of green corn, grown in rainfed system. The experiment was carried out in Forquilha, Ceará state. Two varieties of corn (Sweet and Gorutuba) were used in the experiment, grown in five types of nitrogen fertilization in the crop cycle (one; three; six;

2. Nitrogen top-dressing fertilization of maize cultivated in single and twin-row systems
ABSTRACT The aim of this study was to evaluate the effects of cropping systems (single and twin-rows) and N fertilizer rates in the second top-dressing on the agronomic performance and relative economic returns of maize. The experiment was conducted in a randomized block design, with subplots and three repetitions. The plots were composed of two cropping sys

3. ÍNDICE RELATIVO DE CLOROFILA PARA O DIAGNÓSTICO DO ESTADO DE NITROGÊNIO EM HÍBRIDOS DE MILHO
Nitrogen (N) is the nutrient that contributes the most to increase productivity of corn hybrids. For this reason, the main objective of this study is to determine the relative chlorophyll index (RCI), in different leaves and phenological stages, aiming diagnosing N state in corn hybrids according to the N doses applied in coverage, correlating them with the

5. Resposta da soja a adubacao e disponibilidade de potassio em latossolo roxo alico.
A sucessao soja-trigo tem sido empregada nos Latossolos Roxos alicos do Parana desde a decada de 70. Em todos esses anos, quando houve restricao de credito agricola, a maioria dos agricultores dispensou o uso de adubo ou, quando utilizou, aplicou menos potassio que o retirado pelas sementes. Essa pratica conduz ao empobrecimento do solo e, como consequencia,
