Contenido :  Rice (Oryza sativa L.) systems rotated with perennial pastures have intensified in South America to increase annual grain productivity, but the effects on rice yield and soil quality remain poorly understood. We evaluated rice grain yield, crop and pasture biomass production, and soil organic carbon (SOC) and total nitrogen stocks (0?15-cm depth) in three rice-based rotations over 8 yr in Uruguay. Treatments were: (a) rice?pasture [a 5 yr rotation of rice?ryegrass (Lolium multiflorum Lam.)?rice, then 3.5 yr of a perennial mixture of tall fescue (Festuca arundinacea Schreb.), white clover (Trifolium repens L.), and birdsfoot trefoil (Lotus corniculatus L.)], (b) rice?soybean [a 2-yr rotation of rice?ryegrass?soybean (Glycine max [L.] Merr.)?Egyptian clover (Trifolium alexandrinum L.)], and (c) rice?cover crop (an annual rotation of rice?Egyptian clover). Rice after soybean or pasture achieved the highest yield (9.8 Mg ha?1), 9% higher than rice after rice in the rice?pasture and rice?cover crop systems. Estimated belowground biomass under rice?pasture (2.7 Mg ha?1) was 12 and 42% greater than under rice?cover crop and rice?soybean rotations, respectively. Rice?pasture showed an increase of 0.6 Mg ha?1 yr?1 of SOC; no changes were observed in the intensified rotations replacing pasture with additional rice or soybean. All systems sustained soil total N. These results provide insights for implementing sustainable rice-based rotations, with rice?pasture being the only system tha... Presentar Todo

Contenido :  ABSTRACT. Fusarium Head Blight (FHB) identifi ed in the early part of the twentieth century in South America, remained relatively irregular in appearance till the 1980s. However, the early epidemics recorded in Argentina, Brazil and Uruguay must have been severe enough to wipe out production, thereby forcing wheat breeders to look for sources of resistance among the local varieties and/or landraces that survived. It is these old landraces such as Barletta or Lin Calel and Americano selections from La Plata River basin as well as Polyssu and Alfredo Chaves lines from Brazil that formed the initial base of subsequent commercial varieties with moderate resistance to FHB. While the genetic basis of such locally selected resistance has not been researched, it received a further boost from the introduction of two sister lines from Italy, Ardito and Mentana, which led to development of world famous Frontana and other varieties. Both sister lines have 50 % of contribution from a Japanese variety Akagomoughi used as male parent in the cross. Since the 1970s, the Japanese and Chinese germplasm, fi rstly NobeokaBozu, Nyu Bay and Pekin 8 distributed from Brazil and lately Sumai#3, Catbird and many others distributed by International Wheat and Maize Improvement Center, CIMMYT, in the form of international nurseries have become the backbone of the FHB resistance in the region. Recently, the national wheat breeding programs are exploring the role of synthetic wheats and other alien specie... Presentar Todo
