Effect of different manures on the growth, yield and quality of two brussels sprouts (Brassica oleracea var gemmifera L.)‎ hybrids

Abstract EN

The study was conducted during 2014-2015 at Bakrajo Agricultural Research Station, Bakrajo, Sulaimani, Iraq to investigate the effect of different organic manures (cow 10 and 20 t.ha-1 , sheep10 and 20 t.ha-1 and chicken 4 and 8 t.ha-1 ) on the yield and quality of two Brussels sprouts hybrid “Topline F1” and “Attwood F1”.

The results showed that “Topline F1” increased plant height, leaf weight, leaf area, bud size, yield.

plant-1 , yield.ha-1 and Ascorbic acid .

“Attwood F1” took shorter time to harvest days.

The highest yield.plant-1 , yield.ha-1 and bud number obtained from cow manure 20 t.ha-1 , highest plant height and bud fresh weight obtained from sheep manure 20 t.ha-1 , while the highest leaf number, leaf weight , leaf area and bud size recorded for chicken manure 8 t.ha-1 ..

NPK gave highest protein and nitrate content values.

The highest ascorbic acid obtained from the control treatment.

Shorter period to harvest was recorded for cow and sheep manure 20t.ha-1 .
