SOME MORPHOLOGICAL CHARACTERS AND YIELD OF BROAD BEAN (VICIA-FABA) ASAFFECTED BY PESTICIDE TREATMENTS

Two field experiments were conducted at Giza, Egypt in the winter seas ons of 1990 and 1991, to study the effects of two fungicides (Dithane M45 and Saprol), two insecticides (Rogor and Pirimor), two acaricides (Tedifol and Comite) and two herbicides (Lancer and Cobex) on some mor phological characters and yield of broad bean. The investigated pestic ides were used at the recommended doses.All pesticidal treatments redu ced the percentage of missing plants at harvest. They also, except Lan cer, led to an increase in the total yield of green pods and dry seeds . Individual treatments of Saprol, Dithane M45 and Cobex significantly increased the number and weight of green pods/plant and yield of dry seeds/plant. The individual treatment by Pirimor or Rogor also led to an increment in yield of dry seeds/plant. Lancer proved to be toxic to broad bean plants, as it caused a reduction in the number of branches and plant productivity of green pods and dry seeds.
