| Abstract:
This study was conducted to determine the effects of three planting densities (0.75 x 0.15 m, 0.75 x 0.25 m, 0.75x 0.35 m), and four topping truss (3,4,5,6 per plant) on earliness, quality, early yield and total yield of Vivia F1 tomato under Tokat/Turkey ecological conditions during spring production. The seeds were sown in an unheated double layer highplastic tunnel on 1 March 1994. The seedlings were transplanted to a unheated singly layer high plastic tunnel on 15 April 1994. The planting density and the number of trusses per plant were found to affect early and total yield significantly. Spacing and pruning effects were not found to significantlyaffect first harvest date or earliness. There were no apparent spacing x pruning interactions. Spacing at 0.75 x 0.35 m gave more fruit/plant and heavier individual fruit weight than spacing at 0.75 x 0.25 m or 0.75 x 0.15 m, but yield per unit area was increased bycloser spacing. Plants topped after the 6th truss yielded more fruits than plants topped after the 3rd truss. | |
