the primary aim of plant breeding is to improve stability in yield and to obtain varieties with good quality. for this reason, a study of wheat varieties was conducted in 2010, 2011, and 2012 at the agricultural application and research center fields of the uludag university, agricultural faculty, in bursa/turkey. in the study, 22 advanced lines of bread wheat and gonen, pehlivan, and flamura c...

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 ...

rainfed wheat is the main source of staple food for people in the developing countries. various factors contribute to and affect the production of this crop. the aim followed in the present study was to develop a model to estimate rainfed wheat grain yield as based on physico-chemical properties of the soil. therefore, wheat grain yield and soil physico-chemical properties were separately deter...

Wheat (Triticum aestivum) growth and yield are depressed by physical and chemical interference of weeds. Recently, wild barley (Hordeum spontaneum) population has increased in wheat fields of many provinces of Iran. Since, little is known about the allelopathic effects of wild barley residues in soil, greenhouse studies were conducted to examine the effects of soil amended residues of wild barl...

secale cereale is a nosious, problematic weed of wheat fields in iran. for evaluation of the yield and yield components of bread wheat (triticum aestivum l.) cultivars in the presence of rye an experiment was established in a randomized compelet block design with factorial arrangment of treatments in meshkindasht and varamin during 2002-2003 growin season. experimental factors were wheat cultiv...

"> The present study described the diversity of wheat and barley varieties andlandraces available in farmer’s fields in Syria using different indicators. Analysisof spatial and temporal diversity and coefficient of parentage along withmeasurements of agronomic and morphological traits were employed to explain thediversity of wheat and barley varieties or landraces grown by farmers in Syria.Farm...

long term use of fallow in wheat-based cropping system of dry and semi-dry lands can increase erosion and decrease soil fertility. legumes as substituting crops for fallow could improve sustainability in this area. this study was conducted to evaluate the substituting of some legumes for fallow in a 2-yr wheat rotation at research stations in north khorasan province (natural resources research ...
