Global climate change is predicted to shift seasonal temperature and precipitation patterns. An increasing frequency of extreme weather events such as heat waves and prolonged droughts is predicted, but there are high levels of uncertainty about the nature of local changes. Crop adaptation will be important in reducing potential damage to agriculture. Crop diversity may enhance resilience to cl...

10 Effects of crop growth and physiological activity to drought and irrigation regimes 11 have been extensively studied; however, the responses of plant growth, morphological 12 and photosynthetic behaviors to drought episodes and thereafter rewatering receive a 13 less attention. This field experiment was carried out directly in situ at an agricultural 14 ecosystem research station during 2015...

in order to study the source limitation and contribution of pre-anthesis assimilates to grain in dual-purpose (forage and grain) barley, a field experiment was carried out in iran, ahvaz region. the experimental design was split plot in randomized complete block with three replications. application rates of nitrogen at four levels (60, 120, 180 and 220 kg.ha-1 n) were as main plots, while sub p...

effects of drought stress and chemical treatments was studied on growth and developmental traits of four barley cultivars using a split- split plot design (rcbd) in agricultural research farm, kerman university. main plots consisted of irrigation (control and drought stress after flowering), sub-plots consisted of four barley cultivars ( ʻnosratʼ, ʻafsalʼ, ʻyousofʼ and ʻuh12 lineʼ) and sub-sub ...

Donald A. Wilhite and Kenneth G. Hubbard Center for Agricultural Meteorology and Climatology University of Nebraska Lincoln, Nebraska The ability to collect weather data in near-real time has improved because of technological advances, enabling weather data users to obtain more weather data over wider areas, and in a more timely fashion. The number of near-real time climate networks is increasi...

Under natural conditions, plants suffer different stresses simultaneously or in a sequential way. At present, the combined effect of biotic and abiotic stressors is one of the most important threats to crop production. Understanding how plants deal with the panoply of potential stresses affecting them is crucial to develop biotechnological tools to protect plants. As well as for drought stress,...

background and objectives: suitable tillage methods and planting cover crops are such factors in sustainable agricultural systems, which play an important role in the sustainability of agricultural production systems. minimum and no-tillage systems methods that leave instead of usually more than 30 percent of crop residue on the soil surface, are used to reduce soil erosion, improve soil physic...

Being at the same time a major staple food and a crop very sensitive to weather and price fluctuations, maize is in the core of food security challenges in Tanzania. In a country where agricultural production is mainly driven by smallholder farmers and where the exposure to weather shocks such as drought is likely to increase because of climate change, implementing an efficient and affordable i...
