Climate change is the single biggest threat facing global food system. Irrefutable impacts of climate on systems are recently acknowledged. Therefore, extensive scientific efforts around globe dedicated to investigating and evaluating short long-term effects development systems. In this study, an integrated approach two methodologies, including Moderate Resolution Imaging Spectroradiometer (MOD...

Root system architecture plays a vital role in plant growth, development, and adaptation by absorbing water nutrients providing mechanical support for growing plants. Unfortunately, little information is available the literature on root dynamics of summer mung bean under conservation agriculture conditions. In this study, field experiments were conducted during seasons two consecutive years (20...

Studies of the influence different technologies conventional chernozem cultivation on reserves productive moisture for maize over grain and winter wheat in Steppe zone Ukraine were carried out. The parameters technology growing field crops using “no-till” soil treatment relation to shelf ploughing determined. It was established that system substantially reduces loss due unproductive evaporation...

Agri-environmental indicators such as nutrient balance may play a key role in soil and water quality monitoring, although short-term experiments might be unable to capture the sustainability of cropping systems. Therefore, objectives this study are: (i) evaluate reliability long-term experimental N P estimates predict real field (RF) (i.e., transitory) conditions; (ii) compare short- experiment...

The paper presents comparison of three soil tillage systems in maize, winter wheat and soybean growing on anthropogenic Albic Luvisol in north-west Slavonia, Croatia, during 1996-1999. Tillage systems and implements were: 1. conventional system (CT)-plough, disc-harrow and combined implement, 2. conservation system (RT)-chisel plough and multitiller, 3. no-till system (NT). The aim of testing w...

Remote sensing data provide required inputs for environmental modelling at regional to global scales and play an important role in monitoring agricultural land use with regard to EU agricultural subsidy and sustainable watershed management. To characterise the dynamics of agricultural parcels, it is important to have information about the crop type and the vegetation cover (VC) during the year....

In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been established to obtain adequate moisture for winter wheat production. Current tilled fallow systems receive significant soil erosion through both wind and water. As a result, no-till chemical fallow system...

North China Plain is one of the most important agricultural regions in China with severe challenges of water shortage. Agriculture in the plain is very intensive. Farming in the region is a typical irrigation-supported system of winter wheat, followed by summer maize. Other important crops in the region include cotton, potatoes, soybean and various vegetables. Cultivation of these crops require...

In this study, the structure of the South African wheat market is analysed using economic theory and econometric modelling techniques. The model is used to make baseline projections regarding the supply and use of wheat in South Africa and to analyse the impacts of various policy alternatives on the wheat sector for the period 2004–2008. Results indicate that the area harvested in the summer as...

cultivars, net return is maximized when grazing is terminated at first hollow stem—the stage at which hollow Although grazing of winter wheat (Triticum aestivum L.) is a stem can first be identified above the crown (Redmon common practice in the southern Great Plains, little is known about the efficacy of wheat as a dual-purpose crop in the Nebraska Panhanet al., 1996). However, beyond an optim...
