To investigate the effect of drought stress and plant density on yield and yield components of maize KSc 301 hybrid, a two-year study (2007-2008) was carried out in Varamin Agricultural Research Center by using strip split plot randomized based on complete block design in three replications. Four water stress levels (before flowering, during flowering and grain filling stage and no stress) were...

Development of germplasm resources through importing new genotypes could improve the efficiency of safflower (Carthamus tinctorius L.) breeding programs. During 2014-2015 season, 82 imported safflower genotypes were evaluated in randomized complete block design at the research station of ORDC (Oilseeds Research & Development Company) in Sari. In this plan, six important quantitative traits rela...

Plant growth regulators (PGRs) are used to prevent reduction in wheat grain yield under limited moisture conditions. The effect of 3 PGRs including cycocel, salicylic acid and brassinoestroeid on yield and yield components of  four wheat cultivars (Chamran, Shiroudi, Pishtaz and Sirvan) under well watered and water stress (withheld irrigation after flowering) was examined. The experiment was ca...

In order to investigate the effect of seed priming on yield, yield components and some quality characteristics of rainfed wheat Azar2 cultivar, an experiment was conducted as a randomized complete blocks design with three replications in the Research Field of Kurdistan University, Sannandaj, Iran during two seasons (2018-2020). Priming treatments included control (nonprime), potassium chloride ...

Water deficit is one of the most important abiotic factors limiting growth, which adversely affect growth and crop production. In order to study the relationship between kernel size and phenological characteristics on grain yield, 46 local bread wheat genotypes along with four varieties were evaluated in randomized complete block design with three replications under irrigation and water deficit...
