Resumo: | The objective of this research was to verify the influence of plant residues and the nitrogen fertilization in covering on the mycorrhization (colonization and number of spores of the arbuscular mycorrhizal fungi), and grain yield of upland rice grown under a no tillage system. The experiment was conducted at the Experimental Farm Station of Unesp/Ilha Solteira Campus, at Selviria (Mato Grosso do Sul State). In the main plots, the leguminous were tested: sun hemp (Crotalaria juncea L.), pigeon pea (Cajanus cajan L.) and velvet bean (Stizolobium aterrimum Piper & Tracy) and the grass: corn (Zea mays L.), millet (Peenisetum americamum L.) and grain sorghum (Sorghum bicolor L.), plus no planted area during the winter, as plant cover. In the subplots, after the rice sowing, the nitrogen fertilization in covering (zero and 75 kg ha(-1) of N at the urea form) was used. The rice grain yield was influenced by the plant residues, but not for the N doses or the interaction. The sorghum grain showed negative influence on the rice productivity. The nitrogen fertilization influenced the number of spores, but not the mycorrhizal colonization or the grain yield, at the time of the crop. Correlation between the studied variable was riot found. |
