| Abstract | ||
| EFFECT of foliar application of yeast extract (5 and 10 g/L) at two sawing times (3rdof November and 3rdof December) on growth, yield and some biochemical constituents of faba bean cultivars was evaluated during 2012/2013 and 2013/2014 seasons. Foliar application with yeast extract significantly increased growth of faba bean cultivars after 65 and 85 days of sowing compared with the control. Foliar spraying with 10g/L yeast extract increased chlorophyll and phytohormone contents of all faba bean cultivars at the age of 65 days. Yield parameters as well as seeds protein and carbohydrate responded positively to yeast application. Yield parameters data of Giza 3 and Sakha 4 cultivars had the highest values among the five tested cultivars. In addition, the first sowing time (3rd of November) induced a higher value of yield parameters compared with the second sowing time (3rd of December). It could be recommended that foliar spraying with yeast extract (10g/L) at the first sowing time (3rd of November) caused an increase of the final yield parameters and improved seed quality of all faba bean cultivars. However, the effect was more pronounced in Giza 3 and Sakha 4. | ||
