Abstract
This investigation was carried out under naturally Orobanche infested fields, at Sakha Agricultural Research Station Kafr El-Sheikh Governorate, Egypt. during 2015/16 and 2016/17 winter growing seasons to investigate the effect of sowing date of six faba bean. genotypes(Sakha1,Sakha3,Giza843,Misr3,(Misr1*Misr2)and((Sakha1*Misr1)*(Misr1*Misr2))) on the behaviour of Orobanche. The experiment was carried out under two sowing dates (November first and November 30th). A split plot design, with three replications, was used for each date. Each plot consisted of three ridges, 3m long and 60 cm apart. The seeds were sown in hills distanced at 20 cm. on the two sides of the ridge, at the rate of 2-seeds/ hill. The analysis of variance indicated that sowing dates highly significantly affected faba bean yield and its attributes in the two growing seasons, except for that No. of branches/plant, No. of seeds/plant and seed yield/plant in both seasons, and number of pods/plant, in the first season. Delaying sowing date from Nov. 1st to Nov. 30th significantly decreased plant height, No. of pods/plant in the second season, 100 seed weight (g), in both seasons, seed yield (ardab/fed.), in the first season and No. of Orobanche spikes/plot in both seasons. The lowest values were given by sowing on Nov.30th. The seed yield and its attributes in all evaluated faba bean genotypes were significantly different in the two seasons. Misr1*Misr2 genotype recorded the highest values of seed yield and its attributes., No. of seeds/plant and seed yield/plant of Misr3 recorded the highest values of seed yield (ardab/fed.) On the other hand, Sakha1and Sakha3 recoded the lowest values. Results showed that the interaction between genotypes and sowing date recorded the highest value of seed yield (ardab/fed.) with Misr3, planted in early sowing date. On the other side,the late sowing date with all genotypes recorded higher seed yield and resistant to Orobanche in the two growing seasons, than the early sowing date.
