O dejeto de suínos é uma fonte de nutrientes às plantas que, quando adequadamente manejado, aumenta a fertilidade do solo e a produtividade de grãos. O objetivo deste trabalho foi verificar o efeito de doses de dejeto líquido de suínos (0; 25; 50; 100 e 200 m3 ha-1 ano-1) no rendimento dos grãos de milho cultivados nas safras 2009/2010 e 2010/2011 em sistema de plantio direto. O delineamento experimental consistiu de blocos completos casualizados com quatro repetições, em parcelas de 25 m2, realizado em propriedade rural localizada no município de Braço do Norte, SC. Nas condições estudadas, a aplicação de doses crescentes de dejeto líquido de suínos aumentou o rendimento de grãos de milho, porém somente na dose de 200 m3 ha-1 ano-1 a produtividade foi igual ou maior que a média da região (entre 4 e 6 toneladas por hectare). |

This study aimed to evaluate the interactive effects of orchard fertilization with nitrogen (N) and potassium (K) on physiological disorders of ?Fuji? apples after storage in regular air (RA) or controlled atmosphere (CA). ?Fuji? apple trees were grown on two Brazilian soils (Inceptisol and Entisol) annually fertilized with 0, 50, 100, and 200 kg ha-1 of both N and K2O from 1998 to 2006. In 2005 and 2006, fruits were harvested at optimum maturity for long-term storage, while in 2007 they were harvested two weeks before and two weeks after the optimum maturity. The combination of high N and K rates was associated with the high severity of bitter pit, superficial scald, CO2 injury and core browning. However, this effect depended on soil type, growing season, storage atmosphere and harvest date. The negative effect of high K2O rates on bitter pit, superficial scald and core browning was more evident in fruit grown on the Inceptisol than on the Entisol soil. In 2007, a greater negative effect of high K2O rates on bitter pit and superficial scald occurred in fruit harvested before the optimum maturity and stored in RA, while the effect of high K2O fertilization rates on CO2 injury occurred in fruit harvested after the optimum maturity and stored in CA. Effects of N fertilization rates on all physiological disorders were less consistent than those of high K2O rates. High severity of superficial scald in fruit grown on the Inceptisol was associated to low N rates when K2O rate was the lowest or, on the contrary, it was associated to high N rate when K2O rate was the highest. Since the effect of orchard fertilization varied according to the soil type, different strategies should be considered even for the same geographic region.
