In order to research the effect of harvesting methods on the
yield in some broccoli varieties, four varieties as: V1
(Shogun F1); V2 (Pirate F1); V3 (Sultan F1); and V4
(Marathon F1) and three sowing times as: July, August and
September were used in the study. For single harvest, the
weight of primary shoots and for continuous harvest; besides
the primary shoot weight, the weight and quantity of
secondary shoot and the length of the plant were also
marked. As a result, while the effect of varieties and
characteristics of the plant were not, the sowing time was
significant on harvesting methods. The weights of primary
and secondary shoots, the number of secondary shoots and
plant length were significant in continuous harvesting for
which the yield changed between 550.17 - 68.34 g plant-1.
However, the weight of primary shoot was significant in
single harvest where the yield varied between 526.11 - 68.21
g plant-1. Total yield varied between 3,173.8 - 24,356.7 kg
ha-1 in the single harvest and between 3,163.8 - 25,470.6 kg
ha-1 in the continuous harvest. The head diameters and
harvest times showed uniformity though their effects were
low in the single harvest. Although the yield was high in
the continuous harvest, approaching to the end of harvest
the observation of decreasing marketable product quality and
the requirement of more labour and time in the harvest
stated that the single harvest would be preferred.
Key words: Broccoli, harvesting methods, yield.
