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 that increased SOC while achieving high rice yields and belowground biomass productivity.

Resistance-breaking (RB) isolates of citrus tristeza virus (CTV) can replicate and move systemically in Poncirus trifoliata, a rootstock widely used for management of decline caused by CTV and other purposes. In Uruguay, severe CTV isolates are prevalent, and an RB isolate (designated as RB-UY1) was identified. In order to predict the implications of this genotype circulating in citrus crops grafted on trifoliate rootstocks, the aim of this work was to determine the biological and molecular characteristics of this isolate, the efficiency of its transmission by Toxoptera citricida, and its effects on plant growth performance of P. trifoliata. Our results show that RB-UY1 can be classified as a mild isolate, that it is phylogenetically associated with the RB1 group, and that it is efficiently transmitted by T. citrida. They also suggest that the RB-UY1 isolate should not affect the performance of citrus crops grafted on trifoliate rootstocks, although some growth parameters of P. trifoliata seedlings were affected four years after inoculation. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Austria, part of Springer Nature. |
