in order to evaluate the relationship between grain yield and agronomic characteristics in bread wheat genotypes in different planting dates under rainfed conditions, a factorial experiment was conducted based on rcbd with four replications at gonbad-e qabus region, iran, during 2012-2014 growing seasons. number of spikes per unit area, grain filling rate, effective grain filling period, number...

In the major wheat growing countries, wheat growth and yield are negatively affected by salinity and breed tolerant cultivars through selection and breeding techniques is necessary to solve this problem. Relationship among yield, and its related traits in 23 wheat cultivars and promised lines were studied under salt stress conditions using a randomized complete block design with three replicati...

Crop simulation models are valuable tools for prediction of crop performance under various weather conditions and allow designing methods to limit the negative impacts of adverse environmental constraints. Agricultural Production Systems sIMulator (APSIM) is a comprehensive model that simulates the performance of a wide range of crops in response to climatic, soil and management factors. In thi...

Crop yield, soil properties and erosion are strongly affected by terrain parameters. Therefore, knowledge about the effects of terrain parameters on strategic crops such as wheat production will help us with sustainable management of landscape. This study was conducted in 900ha, of Ardal district, Charmahal and Bakhtiari Province to develop regression models on wheat yield components vs. terrai...

In order to evaluate the productivity of 20 bread wheat promising lines using multivariate statistical methods, an experiment was conducted based on a randomize complete block design under terminal moisture stress, in 2011-2012. Factor analysis showed that the three first factors explained 66% of total variance. Plant height, peduncle length, 1000 kernel weight, harvest index, biological yield,...

Abstract: Wheat grain yield is reduced by post-anthesis drought stress conditions in most wheat growing farmlands of Iran. To evaluate the effect of post-anthesis-withholding irrigation on yield, yield components and canopy temperature of wheat cultivars, a field experiment was conducted as split plot in a completely randomized block design with four replications at experimental farm of coll...

Intercropping often results in increasing production than sole per unit land area, but theunderlying mechanisms are poorly understood. Plants showed different physiologicalcharacteristics in intercropping and sole. However, less information was shown the relationshipsbetween plant aboveground biomass (AB), phosphorus accumulation (PB) and remobilizationand the yield advantage. Here, field exper...

In order to evaluate the morpho-physiological and biochemical responses of six wheat (Triticum aestivum L.) cultivars to late season water deficit stress, this experiment was carried out in controlled conditions at College of Agriculture of Shiraz University, Shiraz, Iran during 2013-14. The experimental treatments were water deficit (50 and 100% F.C.) and wheat cultivars (Sirvan, Chamran, Shir...
