Pest Management Science, EarlyView.The acyclic mucobromic acid, activated by (1S)‐(+)‐10‐camphorsulfonic acid, afforded the chiral compound 1b, precursor for aza‐Michael addition/elimination on the butenolide yielding tetronamides 2b‐7b. Their relative SRSR configuration was confirmed by the spectrometric methods, DFT calculation and statistical methods.

Plant Breeding, EarlyView.ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Mulching does not improve seedling survival or growth during early forest restoration
Restoration Ecology, EarlyView.Abstract Introduction Weed control is one of the main operational challenges and cost components of tropical forest restoration in former pasturelands. Physical barriers (mulches) have been proposed as an alternative to conventional ring weeding because they can suppress competing vegetation while potentially improving the soil microenvironment ...

SHORT-TERM DYNAMIC OF SOIL FERTILITY FROM INTEGRATED CROP-LIVESTOCK SYSTEMS IN TROPICAL SAVANNA
Tropical and Subtropical Agroecosystems, 2017 The chemical attributes and the total organic carbon stock of the soil, from crop-livestock integration systems for renovation of degraded pasture, with fodder sorghum, were evaluated in torpical Savanna.

Restoration Ecology, EarlyView.Abstract Introduction Open ecosystems, such as native grasslands and savannas, cover vast tropical areas and sustain multiple ecosystem services. However, they face intense degradation due to conversion into pastures with exotic grasses that invade natural ecosystems.

Na+ exclusion and proline accumulation in Urochloa spp. cultivars
Pesquisa Agropecuária Brasileira, 2023 The objective of this work was to evaluate the effect of salinity on Na+ and K+ distribution and on proline content in Urochloa brizantha and Urochloa decumbens grass cultivars. Plants were grown in nutrient solution and subjected to salt stress for nine

Effects of irrigated cover crop cultivation period on common bean and soybean yield
Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.Abstract Cover crop inclusion is essential for improving soil management in tropical no till systems; however, the optimal duration of irrigated off‐season cultivation remains uncertain. This 3‐year field study evaluated nine cover crop species or mixtures and four cultivation periods (60, 75, 90, and 105 days) on biomass production, soil chemical ...

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.Abstract Sweetpotato [Ipomoea batatas (L.) Lam.] exhibits low nitrogen (N) uptake during early growth stages, suggesting that N fertilization at planting may be unnecessary. A portable chlorophyll meter can be a useful tool for more precise determination of the timing and rate of topdressed N applications, thereby aligning fertilization with crop ...
