Effect of irrigation frequency and glyphosate (Round up) application on broomrape control and yield of faba bean (Vicia faba L.).

Abstract: Two field experiments were conducted in naturally infested fields with broomrape (Orobanche crenata Forsk.) at Sids Agricultural Research Station, Beni Souif governorate during two successive seasons 2000/01 and 2001/02 to study the effect of both number of irrigations at two, four and six weeks intervals and glyphosate (Roundup) application at 6 & 8, 8 & 10, 6 & 8 &10 and 7 & 10 & 13 weeks after sowing on controlling broomrape, yield and its components in faba bean (Vicia faba L.). Results revealed that irrigation after two weeks interval followed by four weeks intervals caused decreasing on number and dry weight of broomrape by 57.9 & 35.7% and 28.1 & 14.2% in 2000/01 season and 24.2 & 11.5% and 17.9 & 5.9% percent in 2001/02 season, respectively, as compared with six weeks intervals. The same treatment gave the highest values for plant height, number of branches/plant, number of pods/plant, weight of pods/plant, seed weight/plant and seed yield (ardab/fed.) in both seasons. Irrigation for two and four weeks intervals increased significantly seed yield/fed. by 10.2 and 1.6 % & 15.4 and 7.8 %, respectively, in both 2000/01 and 2001/02 seasons compared with irrigation at six weeks intervals.
All broomrape control treatments decreased significantly number and dry weight of broomrape spikes and increased significantly plant height, number of branches/plant, number of pods/plant, weight of pods/plant, seed weight/plant and seed yield (ardab/fed.) in both 2000/01 and 2001/02 seasons. The highest reduction percentage on number and dry weight of broomrape spikes obtained by glyphosate at three times 7 & 10 & 13 were 99.2 & 98.9% and 98.3 & 99.1%, respectively, in 2000/01 and 2001/02 seasons as compared with untreated plots. For seed yield (ardab/fed.) the same treatment gave increases by 56.9 and 266.7%, respectively, in both seasons as compared with untreated treatment.
The interaction between both times of irrigation and glyphosate application was significantly decreased number and dry weight of broomrape spikes and this reflected on yield and its components. These results indicate that heavy infested soil with broomrape it is possible to irrigate at two weeks intervals and spray glyphosate three times to get rid of broomrape injury in faba bean.
