The changes and relationship of climate parameters late-rice yield per unit area during the growth periods from 2010 to 2019 were quantitatively analyzed in order provide scientific guidance for countermeasures against change sustainable production late-rice. include cumulative daily sunshine hours (S), mean temperature (T), precipitation (P), relative humidity (H), highest lowest temperatures ...

Aphid parasitoids are common in Brazilian wheat fields, and parasitize aphids at the wheat tillering stage. However, there is little information available about when this natural enemy occurs in wheat crops. This study investigated the initial occurrence of aphid parasitoids in four commercial wheat crops in northern Paraná during the 2009 crop season. We installed two Malaise traps at each whe...

Infestation of soft spring wheat plants depends on the growth stage and weather conditions growing season. Plants have highest resistance to brown rust in tillering stage. Brown developed 2014 throughout The lowest infestation intensity was during – booting stage, which did not change from experiment variant 5.0 %. spread 10 %, 40 assessed 8 points. In earing increased no fertilizer variants P3...

The current knowledge regarding the effect of global climate change on rice-paddy methane (CH4) emissions is incomplete, partly because information is limited concerning the mechanism of the microbial response to elevated ground-level ozone (O3). A field experiment was conducted in the China Ozone Free-Air Concentration Enrichment facility in a rice-wheat rotation system to investigate the resp...
