To examine the genetic variation for drought stress in chamomile, eight accessions belonging to four species were evaluated under both field and greenhouse conditions using normal and late season drought stress. In the field experiment drought stress were initiated with irrigation cease at the commencement of flowering time. In greenhouse experiment, irrigation carried out at flower initiation ...

Wildfires are often governed by rapid changes in seasonal rainfall. Therefore, measuring seasonal rainfall on a temporally finescale should facilitate the prediction of wildfire regimes. To explore this hypothesis, daily rainfall data over a 58-yr period (1950–2007) in south-central Florida were transformed into cumulative rainfall anomalies (CRAs). This transformation allowed precise estimatio...

In seasonally dry climates, a distinct rainy season is followed by a pronounced dry season during which rainfall often makes a negligible contribution to soil moisture. Using stochastic analytical models of soil moisture to represent the effects of this seasonal change has been hindered by the need to mathematically represent the stochastic influence of wet season climate on dry season soil wat...

A comprehensive survey of the plant parasitic nematodes associated with cowpea (Vigna unguiculata) production fields was carried out in the three primary agro-climatic zones of Burkina Faso in West Africa. Across the three zones, a total of 109 samples were collected from the farms of 32 villages to provide a representative coverage of the cowpea production areas. Samples of rhizosphere soil an...

Rainfall seasonality and timing are key climatic features affecting crop yield in rainfed agriculture (RFA). We evaluated the dynamics of temporal rainfall attributes – strength seasonality, date onset, cessation, duration rainy season over RFA areas across Ethiopia for period 1981-2010 explored their impacts on cereal production (including maize, teff, sorghum, wheat, barley, millet, oats rice...

In the semi-arid tropics (SAT), 33% areas are occupied by Alfisols and related soils. In SAT these soils have low structural stability and thereby tend to form seal and crusts at the surface. Due to this a large proportion of the rain that falls on Alfisols during the early part of the rainy season, is normally lost as runoff thus causing high soil loss as well as moisture stress to crops. Two ...

Increasing rice production has become one of the ultimate goals for South Asian countries. The yield and area under are also facing threats due to consequences climate change such as erratic rainfall seasonal variation. Thus, main aim this work was find out supply response in Malaysia relation both price non-price factors. To achieve target, time series analysis conducted on data from 1970 2014...

Seasonal rainfall forecasts provide information several months ahead to support decision making. These may use dynamic, statistical, or hybrid approaches, but their comparative value is not well understood over Central America. This study conducts a regional evaluation of seasonal focusing on two the leading dynamic climate ensembles: Copernicus Climate Change Service forecasting system (C3S) a...
