الملخص الإنجليزي

An experiment was carried out in 2013-2014 at Ainkawa Agriculture Research Center., to study the response of some oat (Avena sativa L.) cultivars to clipping at different intervals and its effect on growth, yield and quality.

Three oat cultivars were compared to response to five clipping intervals .The factorial experiment was arranged according to randomized complete block design with three replications, differences among treatment means were tested using Duncan's multiple range test at 5% level of significant.

The results shown that oat varieties varied significantly in number of days from sowing to each of flowering stage, maturity stage and harvest time, the highest period (124.67 ,173.33 and 173.92) days were recorded for the mentioned stages for Possum , Kangaro and Kangaro respectively.

ICARDA and Possum recorded highest stem height and flag leaf area which were 55.87cm and 20.58 cm2 respectively.

While the highest value was recorded for the clipping interval from sowing to harvesting for fodder at 105 days after planting and 50% flowering was affected significantly on green fodder and dry matter yield; the highest values were 3996.67 and 1441.3 kg .ha-1 respectively.

The significant interaction effect of varieties and clipping intervals on the period to flowering ,maturity and harvesting stages ,their values were (136.33, 180.33 and 182.00) days for interaction treatment(ICARDA short and clipping after 105 days).

Significant differences for seed yield and straw yield were recorded from the treatment combination of (ICARDA x no clipping).
