Brazil is one of the countries that has most agricultural area under no-till (NT) management. This research study aims to evaluate life-cycle greenhouse gas (GHG) emissions from maize (M) grain production in agroecosystems used different cover crops NT management southern Brazil. The data for this were a long-term 41-year field experiment evaluated effects fallow (F) and (oat (O), vetch (V), cowpea (B), pigeon pea (P), lablab (L)) on nitrous oxide methane soil carbon (C) sequestration agroecosystems. Five cropping systems, FM, OV/M, OV/MB, PM, LM, evaluated. Our results show can reduce GHG by ~40 >100% through increased C sequestration. with winter (OV/M OV/MB) had higher (0.5 kg CO2e kg−1 M or 2.6 Mg ha−1) than agroecosystem F (0.06 0.2 ha−1). Summer (P L) resulted negative (an average −0.2 M−1 −1.2 yield. shows

Integrated Evaluation of Sustainability and Quality of Italian Tomato Cultivars Grown Under Irrigated and Non-Irrigated Systems

Agriculture, Journal Year: 2025, Volume and Issue: 15(4), P. 416 - 416

This research aimed to assess how irrigation can affect the sustainability and quality of two Italian tomato cultivars: “Riccio di Parma Casertano,” which is grown without irrigation, “Piennolo del Vesuvio DOP,” requires irrigation. Life cycle assessment water footprint analysis were used for assessment, while, content bioactive compounds was analyzed by UV-Vis spectrophotometric assays. The results indicate that ‘Riccio Casertano’ a more sustainable cultivar than ‘Piennolo DOP’, with lower environmental impacts in all 18 impact categories, showing reductions ranging from 54.55% 99.90%. higher performance Casertano” also characterized increases +32% total polyphenol +43% flavonoid as an adaptive response stress compared DOP”. However, DOP” has yield better overall nutritional functional quality, concentrations hydrophilic lipophilic compounds, such lycopene β-carotene, due results, therefore, show choice between cultivars might depend on trade-off quality. In particular, ’Riccio could excel contexts low availability while maintaining good profile synthesis compounds; other hand, offer qualities, although it needs improved agricultural practices reduce impacts.
