O objetivo deste trabalho foi avaliar resposta do arroz (Oryza sativa L.), em sucessao ao feijoeiro, a calagem, e aos macro e micronutrientes. O experimento desenvolveu-se em casa de vegetacao, com solo organico coletado na regiao norte fluminense. Os tratamentos, num total de 12 e aplicados apenas por ocasiao do cultivo do feijoeiro, constituiram-se de: testeminha (solo natural), "completo" (N,P,K, calcareo S,B,Co,Cu,Mo e Zn) e "completo" menos um nutriente de cada vez. O delineamento experimental foi o de blocos ao acaso, com quatro repeticoes. Apos a colheita do feijoeiro, o solo permaneceu nos vasos ate instalacao do experimento com o arroz. Fez-se a adubacao com N, P e K, quando pertinente, e avaliou-se o efeito dos tratamentos na producao da parte aerea da planta e na acumulacao de nutrientes. Apenas a testemunha e os tratamentos nos quais se omitiu o N ou o K apresentaram decrescimo significativos na producao de materia seca em comparacao com o tratamento "completo", ou seja, 59, 49 e 38% respectivamente. O acumulo de nutrientes na parte aerea do arroz ocorreu na seguinte ordem: N>K>Ca>P>Mg>S>Fe>Mn>Zn>Cu>B. |

The aim of the present study was to verify associations between reproductive efficiency and four microsatellite markers located in synteny with genes involved in the regulation of reproductive mechanisms. A sample of 107 females from a Brangus Ibagé population (5/8 Aberdeen Angus x 3/8 Nelore) was characterized for ETH225 (D9S1) and MM12E6 (D9S20) microsatellites, mapped on chromosome 9, and HEL5 (D21S15) and AFZ1 (D21S37) on chromosome 21. Associations between the genetic markers and reproductive efficiency were determined by one-way analysis of variance using calving interval (CI), live weight at calving (LWC), live weight at first calving (LW1C) and live weight at second calving (LW2C) as dependent variables. The genotypes were classified according to allele size into homozygous for long alleles, homozygous for short alleles and heterozygous. A longer CI was observed for individuals homozygous for long alleles at the HEL5 locus compared with the others (p = 0.022). For the AFZ1 locus, an inverse correlation between allele size and calving interval was observed (p = 0.022), suggesting that homozygosity for long alleles at this microsatellite could be advantageous. Analysis of the combined effect of favorable genotypes at HEL5 and AFZ1 indicated that animals with unfavorable genotypes (homozygous for long alleles at HEL5 and homozygous for short alleles at AFZ1) presented a significantly longer CI (p = 0.003) when compared to the other genotypes. The ETH225 and MM12E6 systems did not present any association with CI. None of the systems studied showed any significant association with LWC, LW1C or LW2C.
