اثر هرس و فاصله بين بوته ها بر روي عملكرد و اجزاي عملكرد كدوي تخم كاغذي (Cucurbita pepo L .)

Effect of bead pruning and between_row spacing on yield and yield components of pumpkin (Cucurbila pepo L.).

To evaluate the effect of between row, spacing and head pruning on seed yield and yield component of pumpkin a factorial experiment based on randomized complete block with three replication carried out in Agricutural Research Station of Ardabil at 2005. Treatments include three between row spacing (0.3, 0.6 and 0.9 m) and head pruning (no head pruning and head pruning after 12 and 16 node formation). Result indicated that the in row spacing of plants had significant effect on number of sub brunches, leaf, situation of first fruit on stern, fruit diameter, weight of 1000 seeds, fruit and seed yield per hectar . Also result showed that the head pruning had significant effects on all traits except mean fresh weight of each fruit, fruit diameter. seed number per fruit, weight of 1000 seeds. The favorable results obtained from 0.3 m inJow spacing and head pruning after 12 node formation.
