82%) and dry weight (> 90%) of broomrape spikes/m2 were obtained by application of fenugreek along with Imazapic herbicides twice in both seasons.
Repeating foliar spray with either Imazapic or Glyphosate on faba bean plants resulted in a significant decrease in photosynthetic pigments (chlorophyll a, b and total chlorophyll) content in leaves compared with untreated treatment in both seasons. All photosynthetic pigments contents were significantly greater in leaves of faba bean fertilized by N fertilizer than in those of sole faba bean plants without N fertilizer or intercropped with fenugreek or oat in both seasons. Foliar spraying of the two herbicides once or twice on faba bean significantly increased plant height, number of branches and pods/plant, 100-seed weight, seed yield/plant, seed and biological yields/fed. of faba bean compared with untreated treatment in both seasons. Faba bean plants sprayed twice with of Imazapic herbicide significantly exceeded those sprayed once with Imazapic or Glyphosate herbicides in seed and biological yields as well as its attributes in both seasons. Faba been intercropped with fenugreek or fertilized with NH4NO3 produced significantly taller plants and greater seed and biological yields as well as its attributes than did sole faba bean without N fertilizer in both seasons. The combination of Imazapic herbicide twice and fenugreek recorded the highest seed yield, while sole faba bean plants without N fertilizer and untreated produced the lowest one in both seasons. It can be concluded that foliar spraying with Imazapic or Glyphosate twice on faba bean intercropped or fertilized with NH4NO3 could be recommended for optimum broomrape parasitic weed control and highest seed yield at Kafrelsheikh Governorate, Egypt.]]>
