NUTRIENT DEFICIENCIES FOR THE IRRIGATED RICE IN SUCCESSION TO THE BEAN PLANT IN LOWLAND SOIL

This study aimed at evaluating the response in bean-rice rotation rela ted to liming application and macro and micronutrients fertilization. This experiment was conducted in a greenhouse, in an organic soil from the Northern Fluminense region. The following treatments to bean plan ts were considered: control (natural soil), ''complete'' (N, P, K, lim estone, S, B, Co, Cu, Mo, and Zn) and ''complete'' but one by one of t he related nutrients. The experimental design was a randomized block w ith four replications. After the bean harvest, rice seeds were planted in the same previous soil used (pots), adding N, P and K according to recommendations. The effect of treatments was measured by dry matter production considering plant shoot and nutrient accumulation. Only the control treatment and the others without N or K showed a significant decrease in the dry matter production in comparison to the ''complete' ' treatment, such as 59, 49 and 38% for the control treatment and the treatments without N and K, respectivelly. The nutrient accumulation b y the aerial part of the rice occured on the following arrangement: N> K>Ca>P>Mg>S>Fe>Mn>Zn>CU>B.
