| Abstract | ||
| Two experiments were conducted on cabbage at the wire – house in Weed Research Section, at Sakha Agricultural Research Station, Kafr - El-Sheikh Governorate during 2009/10 and 2010/11 seasons. The objective of the present study was to investigate, the efficacy of some herbicides on controlling broomrape as parasite weed under two sources of mineral nitrogen fertilization (ammonium sulfate and ammonium nitrate). The cabbage cultivar, Brunzwick, was used. Broomrape control treatments were Bendimethalin at 750 ga.i./fed., incorporation in soil, Glyphosate at 36 g/a.i/fed., Imazapic at 20 g/a.i/fed. twice, hand pulling twice, and weedy check. Results indicated that ammonium sulfate decreased number and weight of broomrape spikes/m², spikes length and number of capsules/spikes, during 2009/10 and 2010/11 seasons, but increased cabbage yield (7.3 and 6.4%), as compared with ammonium nitrate during both seasons. Results also showed that all broomrape control treatments exerted significant efficiency in controlling broomrape: Imazapic twice, gave the best broomrape control and the highest increase in cabbage yield and quality , followed by Glyphosate, and hand pulling, twice. Thus, the herbicides Imazapic and Glyphosate decreased number and weight of broomrape spikes/m2, spikes length and number of capsules/spike. Also, all tested herbicides gave the highest significant increase in the head quality characters in cabbage. The best treatments for increasing the number and weight of edible leaves were Glyphosate, Imazapic and hand pulling, twice; the highest head quality was obtained by Glyphosate and Imazapic; while the highest increase in head characteristics was observed by the hand pulling, twice, Glyphosate and imazapic treatments. Yield increases were estimated by 85.7, 73.1 and 62.1%, respectively in first season and by 65.4, 83.8 and 49.1%, in second one, respectively from Glyphosate, Imazapic and hand pulling, twice Glyphosate, Imazapic and hand pulling twice as compared with weedy check. Thus, these herbicides treatments can replace hand pulling for controlling broomrape weed in cabbage crop. | ||
