INFULENCE OF SPRAYING TIMES OF SOME CHEMICAL SUBSTANCES ON YIELD AND SHEDDING OF FIELD BEAN
Two field experiments were conducted during the two winter growing seasons of 2003/2004 and 2004/2005 at Meet-El Ameel village, Dakhlia, Egypt. Accordingly, the present study was designed to investigate the influence of spraying times of some chemical substances (Berelex ]GA3[, Amcotone ]NA+NAA [and Ridomil ]Mancozeb + Metalaxyl [) as well as water (control treatment) and their interactions on growth, flowers and pod setting and shedding as well as yield components and seed yield of faba bean (vicia faba, L.) cv. Sakha1. Strip plot design with four replicates was used. The most important findings could be summarized as follows:
1- Applying chemical substances (Berelex at 100 ppm), (Amcotone at 600 ppm) and (Ridomil at 2500 ppm) as foliar spraying on faba bean plants markedly increased plant height, leaf area index (LAI), number of setting flowers per plant, seed yield and its attributes.
2- Times of spraying of chemical substances showed different effects on growth and yield attributes. More, foliar spraying at 35 followed by 45 DFS markedly improved growth and faba bean yields compare
d with the other of times of spraying.
3- The interaction between chemical substances and times of spraying had significant effects on plant height, setting flowers, number and weight of pods, 100-seed weight and seed yield (Ardab/fad).
4- Generally, the maximum vegetative growth characters, controlling shedding of flowers and pods, seed yield as well as yield components were achieved due to chemical regulating (Berelex and Amcotone) when spraying at early times (35 and 45 DFS).
