Conteúdo:  Suitable nitrogen (N) fertilisation is key for economic and environmental sustainability of croplands, and little is known on the potential of slow-release N sources to mitigate nitrous oxide (N2O) and methane (CH4) emissions in paddy rice growing in subtropical lowlands. We assessed the impact of controlled-released N fertiliser (CRNF) on partial global warming potential (pGWP) and yield-scaled greenhouse gas (GHG) emissions (GHG emission per unit of yield) in comparison to common urea in irrigated rice growing in a Typic Albaqualf in southern Brazil. The field experiment comprised four treatments: (1) control; (2) common urea applied into three splits, and CRNF applied at rice sowing; (3) on soil surface; and (4) in the seeding furrow. The N fertilisers did not increase N2O emissions when compared to control with exception of CRNF at the seeding furrow. However, N fertilisation increased CH4 emissions, with exception of the CRNF applied to the seeding furrow. Rice grain yields (7954?8637 kg ha?1) were not affected by N sources. The pGWP (11 683?14 297 kg CO2 eq ha?1) and the yield-scaled GHG (1.47?1.74 kg CO2 eq kg?1 grain) were similar among N sources. N fertilisation is a crucial practice to obtain high rice yields, which did not affect negatively the yield-scaled GHG emissions in this subtropical environment under continuous flood irrigation. CRNF applied at rice sowing provides rice grain productivity and agronomic efficiency similar to common urea applied into three s... Mostrar Tudo

Título:  Performance of grain sorghum hybrids under drought stress using GGE biplot analyses.
Ano de publicação:  2017

Conteúdo:  The objective of this study was to estimate the adaptability and stability of grain sorghum hybrids grown under post-flowering water stress and non-stress conditions. The trials were carried out in Nova Porteirinha-MG during the season of 2014 and 2015, and in Teresina-PI in the 2014 season. Twenty-nine-grain sorghum hybrids were evaluated, in a randomized complete block design, with three replications. Plots consisted of four lines with 3 m long. The grain yield data were submitted to the individual variance analysis, having considered the effects of the hybrids as fixed and the other effects as random. The joint analysis was carried out, and when the interaction genotypes x environments was significant, the grain yield data were submitted to the adaptability and stability analysis by the GGE biplot method. A substantial reduction in the grain yield in environments with water stress was found. The highest yielding hybrids under water stress conditions in Nova Porteirinha-MG were 50A50, AG1080, AG1090, DKB550, DKB590, Jade, and BM737, and the highest yielding hybrids under the water stress in Teresina-PI were 1G282, 1G244, and A9721R. Considering all environments, the highest yielding hybrids were 1G282, DKB540, A9721R, 1G100, and AG1090.
