Determination of green pod yield and some pod characteristics of faba bean (Vicia faba L.) cultivar/lines grown in different row spacings

摘要

This study was conducted to determine the effects of row spacings (30, 50 and 70 cm) on green pod yield and some pod characteristics of Vicia faba L. cv. Eresen-87 and two faba bean lines provided from ICARDA (V7: FLIP 85-172 FB and V9: FLIP 86-116 FB) in Samsun for three consecutive seasons (1997/1998-1999/2000). This trial was planned in split-plot design with three replications. Faba bean cultivar/lines were placed to main plots and row spacing to subplots. Sowing was performed in autumn. In the present study, pod length, width and thickness, pod flesh thickness, pod/plant and green pod yield per hectare were investigated. Green pod yields obtained from Eresen-87 (9.15 t/ha) and V7 line (8.18 t/ha) were not statistically different, but higher than that of V9 (7.73 t/ha). Green pod yield was reduced with increasing row spacings. The narrowest row spacing (30 cm) gave the highest green pod yield (11.64 t/ha) due to higher number of plants per unit area. Green pod yields of 50 and 70 cm row spacings were found 7.61 and 5.81 t/ha, respectively.
