تأثير الحش في نمو و حاصل الحبوب و العلف الأخضر لبعض أصناف حنطة الخبز

Abstract EN

In order to provide green fodder in times of scarcity and lack of availability for animals in winter and investigate their impact on the quotient of grain, carried field experiment by planted varieties of wheat bread certified (Fateh, IPA99, Abu Ghraib, Mexibak) on 28 Nov.

2011, and 25 Nov.

2012, the design of RCBD for three replications in the Abu Ghraib Research Station-Agricultural Research Office.

Conducted cut first and second when a plant height 35 cm.

The results showed that the characteristics of growth , green fodder , dry matter weight of green fodder , biological yield decreased significantly after first cutting and second for both years, respectively.

The results showed that grain yield varieties fell by 17% and 27% after the first cutting and 35% and 50% after the second cutting in decreased biological yield 10% and 22% after the first cutting and 21% and 39% after the second cutting for both years, respectively.

Reached the green fodder 12.460 and 13.963 t.h-1 when the first cutting , 10.82 t.h-1 and 11.556 t4h-1 in the second cutting, a weight of 1.204 t.h-1 of dry matter, 1.325 t/h after the first cutting, 1.141 t.h-1 and 1.224 t.h-1 after the second cutting for both years, respectively.

We conclude from the study the possibility of providing green fodder of varieties of wheat bread local under study for their ability to grow after cutting and giving grain yield acceptable after once or twice cutting from one cultivation.

Variety IPA99 gave a higher grain yield (3.410 and 5.065) t.h-1 after the first cutting with two types gave Mexibak and Fateh (2.640 and 3.613) t.h-1 after the second cutting sequentially in both the research years.
