تأثير معاملات التسميد في بعض الصفات المورفو- فيزيولوجية و الإنتاجية لأصناف من القمح

الملخص EN

This experiment was conducted in the fields of faculty of agriculture, Damascus University (Syria) during two growing season of 2009/ 2010 and 2010/ 2011, to study the effect of fertilization treatments on some morpho-physiological traits of durum wheat cultivars (Hourani, Cham1 and Cham3 ) and bread wheat cultivars (Bohouth6, Bohouth8 and Cham4).

The experiment designed in split plot design in three replications.

The statistical analysis results showed significant differences among cultivars and between fertilization treatments in plant height, leaf area index, number of spikes per plant, number of grains per plant, thousand grain weight and grain yield.

The variety Bohouth8 surpass over other varieties in plant height (89.13 cm), number of spikes per plant (9.33) and grain yield (4542.25 kg/ha), which reflect the importance of cultivar efficiency in converting vegetative tillers into productive tillers as main factor in formation the yield of grains, as the number of spike per plant consider one of the most important components determining grain yield in wheat crop.

The fertilization treatment through integration of organic manure and inorganic fertilizer surpassed over all other fertilization treatments which reflect the importance of providing balance nutrition especially during critical stages of plant life to get higher yield of grains.
