Crop sequence is an important management practice that may affect durum wheat (Triticum durum Desf.) production. Field research was conducted in 2007-2008 and 2008-2009 seasons in a rain-fed cold Mediterranean environment to examine the impact of the preceding crops alfalfa (Medicago sativa L.), maize (Zea mays L.), sunflower (Helianthus annuus L.), and bread wheat (Triticum aestivum L.) on yie...

  Crop yields are dependent on a number of factors such as soil type, weather conditions and farming practices. Crop yield estimates in different soil types are required to meet the needs of farmers, land appraisers, and governmental agencies in Iran as around the world. This study was conducted to model the wheat-grain yields [Triticum aestivum L.]  by soil properties in Khoy area, the north-w...

C rop and fertilizer management practices can increase wheat grain protein without sacrificing yield. Growing wheat with high grain protein begins with selecting the appropriate variety and providing enough fertilizer to meet the wheat’s requirements for growth and grain yield. If nutrient levels are sufficient to meet yield goals, then providing adequate available nitrogen (N) may be the most ...

The loss of kernels lowers the yield, whereas damaged kernels reduce the grade of the harvested wheat. Standards established by the Canadian Grain Commission limit midge damage in No. 1 CWRS and No. 2 CWRS to 2 per cent and 8 per cent respectively, before grade is affected. Damage tolerances for amber durum are 2 per cent for No. 1 CWAD and 8 per cent for No. 2 CWAD. However, if disease associa...

The remobilization of water soluble carbohydrates (WSC) has an important role for grain yield. This study investigated the accumulation and remobilization of WSC in non-leaf organs (chaff, upper stem, and lower stem) and their contribution to grain yield, under different irrigation levels (rainfed, reduced irrigation, and full irrigation) and seeding rate treatments (450, 600 and 750 plants...

Due to increasing scarcity of fresh water, use of unconventional water source (e.g., wastewater) in irrigation has now become important. However, inclusive information on the effects of wastewater on crop production and soil health is necessary for such intervention. This study was designed to evaluate these effects by demonstrating the contribution of municipal wastewater (hereafter called was...

drought stress is one of the most important abiotic stresses which can affect the growth of a plant, thereby curbing crop yield. identification of effective morphological traits is the main aim of each breeding program. our objective was to identify agronomic traits associated with changes in grain yield of wheat under irrigated and drought conditions. to address this objective, grain yield and...

in order to determine traits which affected grain yield in optimal irrigation and terminal drought deficit conditions, a field experiments with 16 spring bread wheat genotypes as randomized complete block design with three replications conducted in neishabour during 2009-10 cropping seasons. results of combined analysis of variance showed, significant differences between many of traits vegetati...

Beginning in 2012, research was conducted Garden City and Tribune, KS, to determine the effect of a single tillage operation every 3 years on grain yields wheat-sorghum- fallow (WSF) rotation. Grain wheat sorghum were generally not affected by WSF yield varied greatly year from 2014 2020. Wheat ranged across mid-20s 90 bu/a at Tribune less than 10 100 City. 40 greater 140 bu/a, depending upon l...
