The change in land use and the expansion of mechanized sugarcane production systems have led to an increase soil compaction levels. Preconsolidation pressure may be used as a useful measure for mechanical state, management, planning mechanization systems. This study aimed assess compressive behavior, physical properties, spatial variability preconsolidation Oxisol fields under burned harvest effects change. attributes (granulometry, water content, bulk density, total porosity, macro microporosity) were evaluated at 0.00–0.10-m, 0.10–0.20-m, 0.20–0.30-m layers. load-bearing capacity models constructed from σp values contents. We mapped assessed crossing points sampling mesh with regular 10 m intervals each area them via geostatistics.

Soil structure has a significant impact on sugarcane production. This research evaluated the effects of controlled traffic soil physical quality (SPQ). The following four management systems (MS) were evaluated: rainfed cultivation and application vinasse (RV); irrigated (I); (IV), native vegetation (no or irrigation; NV) as reference. samples collected within rows (WR) between (BR) (used exclusively for agricultural machinery traffic) from mini-trenches visual evaluation (VESS) based scale 1 to 5. Disturbed undisturbed measuring indicators SPQ.All SPQ variables differed (p < 0.05) WR BR, demonstrating efficiency SPQ.

The objective this study was evaluate impact burned unburned systems on occurrence annual harvests. For study, an area were selected. gap number length (sum gaps, m) measured after planting plant-cane stages first, second, third ratoon results revealed that there no difference between systems. However, considerably increased second harvest both treatments (burned unburned). close 5 1–5 m at around 60 70 as progressed, respectively, harvesting.

Abstract To enhance weed control in sugarcane systems, the application of herbicide association is widely practiced. This approach broadens spectrum and ensures a successful yield. Therefore, this study aimed to assess efficacy combinations controlling Rottboellia exaltata (itchgrass) Ipomoea quamoclit (morningglory) during pre-emergence while also evaluating potential impact on variety RB85 5156. The experimental design employed randomized block structure with seven treatments four replications. were as follows: 1 - no application; 2 indaziflam + sulfentrazone (120 750 g i.a ha − ); 3 diclosulam 110 4 tebuthiuron 900 5 flumioxazin (150 ), 6 pyroxasulfone (200 200 ) 7 clomazone (1,080 ). following parameters evaluated: percentage itchgrass morningglory control, green coverage (Canopeo® system), biomass (g m height. Tiller counts assessed characterize effects herbicides plants. Several associations have been proven effective alternatives for managing morningglory. most diclosulam, whereas morningglory, top performers sulfentrazone, tebuthiuron, sulfentrazone.
