Plant phenology, i. e. the timing of life cycle events, is related to individual fitness and species distribution ranges. Temperature one most important drivers plant phenology together with day length. The adaptation their may be for success invasive species. present study aims at understanding how performance legume Lupinus polyphyllus vary latitude. We sampled data across a >2000 km l...

livestock industry (CGC, 1996). Barley is also used for malt production and a small amount is used for human Understanding the phenological development of barley (Hordeum food. Understanding the development of barley in this vulgare L.) grown under field conditions in its major growing area in the northern Great Plains, the Canadian province of Alberta, is environment is crucial to continued ad...

The impact of global warming on crop growth periods and yields has been evaluated by using models, which need to provide various kinds input datasets estimate numerous parameters before simulation. Direct studies the changes climatic factors observed yield could a more simple intuitive way for assessing climate change production. In this study, four cultivars were planted over than 15 years in ...

[1] We develop a modeling framework to investigate the influence of the North Atlantic Oscillation (NAO) on phenological variability in Europe through its influence on the distribution of wintertime synoptic-scale surface temperature variability. The approach employs an eigendecomposition of NCEP daily winter surface temperature estimates from the latter twentieth century to represent the spati...

Application of plant growth regulators to hybrid bermudagrass [Cynodon dactylon (L.) Pers. × Cynodon transvaalensis Burtt Davy] putting greens is a common management practice used reduce clipping yield and improve aesthetic functional turfgrass quality. Growing degree day (GDD) models have explored the effects regulator application timing on ultradwarf yield. However, there need for research ev...

El Niño and La Niña Southern Oscillation (ENSO) are major drivers that affect climatic variables in many countries. Therefore, ENSO mediated variation factors have significant consequences for crop production. We studied variations temperature rainfall the five coastal districts of Bangladesh during 1951–2017, impacts on crops production were analyzed using growing degree day (GDD) index. Stati...

The distribution of hookworm in schistosomiasis-endemic areas in Brazil was mapped based on climate suitability. Known biological requirements of hookworm were fitted to data in a monthly long-term normal climate grid (18 x 18 km) using geographical information systems. Hookworm risk models were produced using the growing degree day (GDD) water budget (WB) concept. A moisture-adjusted model (MA...

in order to determine the critical period of weed control (cpwc), yield and yield components of black seed (nigella sativa l.) affected by weed competition and control periods, a field experiment was conducted based on randomized complete block design with 12 treatments and three replications at the agricultural research station, ferdowsi university of mashhad, iran in 2012. two sets of weed-in...
