Evaluation of yield and yield components of facultative and winter bread wheat genotypes (Triticum aestivum L.) under different irrigation regimes in Khorasam Province in Iran



Evaluation of yield and yield components of facultative and winter bread wheat genotypes (Triticum aestivum L.) under different irrigation regimes in Khorasam Province in Iran



Journal of Agronomy 3(3): 184-187



Twenty bread wheat cultivars were subjected to irrigation at 10-, 20- and 30-day intervals in a field experiment conducted in Iran during 1998-2000. Grain yield, total biomass, number of spike/m2, harvest index and 1000-kernel weight decreased with increasing irrigation intervals. Water use efficiency was highest with irrigation at 20-day intervals. Grain yield, biological yield and number of spikes/m2 were high in cultivars C-75-6, C-75-10 and C-75-16, regardless of the treatment.
