Durum wheat as affected by water stress conditions in the presence of added compost for increasing the productivity [electronic resource].

Includes references.

Two pot experiments were carried out in a matting house under natural environmental conditions of Al- Haram area, Giza, Governorate during 2009/2010 and 2010/2011 seasons to study the effect of water stress ( 70, 80 and 90% ) of evapotranspiration (ET) and 3 rates of compost ( 2, 4 and 6% ) of soil weight ( 16kg in each pot ) on some growth parameters , yield and yield components of durum wheat varieties Banysweif -1 , and Banysweif-4 The complete randomized design with six repetitions and factorial arrangements were used . The obtained results revealed that , increasing water irrigation level from 70 up to 90% of ET increased , leaf area/plant , plant height and dry weight/plant. Yield and yield components followed the same manner , such as No. ?f spikes/plant and No. of grains /spikes. Application of 6% compost had a positive and significant effect on the studied parameters either related to plant growth stage or yield The difference between the two durum wheat vanetles reached the level of significance and Banysweif -4(V2) ranked first for all characters under study i.e. growth or yield . All the studied characters were affected significantly by the first and second order interactions . in both seasons. Subjected Banysweif 4 to water irrigation at 90% of ET and fed with 6% of compost gave the greatest values for all parameters under study.
