Abstract: Applications of remote sensing using unmanned aerial vehicle (UAV) in agriculture has proved to be an effective and efficient way of obtaining field information. In this study, we validated the feasibility of utilizing multi-temporal color images acquired from a low altitude UAV-camera system to monitor real-time wheat growth status and to map within-field spatial variations of wheat ...

Improving photosynthesis to raise wheat yield potential has emerged as a major target for wheat physiologists. Photosynthesis-related traits, such as nitrogen per unit leaf area (Narea) and leaf dry mass per area (LMA), require laborious, destructive, laboratory-based methods, while physiological traits underpinning photosynthetic capacity, such as maximum Rubisco activity normalized to 25 °C (...

In this experiment the effect of inoculation with Azospirillum on the flag leaf and spike rachis anatomical features and also on grain yield and grain weight was investigated for the first time in bread and durum wheats during 2015-2016 growing season under semi-arid condition. The crop yield increased due to the inoculation with Azospirillum with a maximum yield increase of about 8.0 per cent ...

Agriculture of the inland arid region in Xinjiang depends on irrigation, which forms oasis of Northwest China. The production and water use of wheat, a dominant crop there, is significantly affected by undergoing climate variability and change. The objective of this study is to quantify interannual variability of wheat yield and water use from 1955 to 2006. The farming systems model APSIM (Agri...

Food security can be under threat due to climate change, which has the potential alter crop yield. Wheat, maize, and rice are major crops contributing global food security. The impact of change on yield with different models techniques been projected; this article reviewed worldwide future wheat, rice, maize production. Wheat yields may increase in colder regions decrease countries near equator...

Landscape-scale variation is a source of information that increasingly is being taken into consideration in agricultural and environmental studies. Models that encompass and interpret this variation in ®elds and across contrasting management practices have the potential to improve the landscape management of agroecosystems. Our objective was to compare the results of two approaches, analysis of...

Drought has been a major cause of agricultural disaster, yet how it affects the vulnerability of maize and wheat production in combination with several co-varying factors (i.e., phenological phases, agro-climatic regions, soil texture) remains unclear. Using a data synthesis approach, this study aims to better characterize the effects of those co-varying factors with drought and to provide crit...

-Wheat is the most important crop of many countries including Pakistan. Assessment of Yield stability of wheat in different environments has been an important issue for wheat growers and horticulturists. In present paper yield stability of wheat genotypes is assessed at different research institutions/stations across the country using univariate parametric stability models and interrelationship...

in order to evaluate the effects of yield and yield components and weed diversity and density in row intercropping for wheat and canola, a field experiment was conducted based on a complete randomized block design with three replications at the agricultural research station of ferdowsi university of mashhad, iran during two growing seasons of 2008-2009 and 2009-2010. treatments included four pa...
