Effect of transplanting date on vegetative characters, leaf pigments and yield of some cauliflower hybrids under sandy soil conditions [electronic resource]

This work was carried at a private vegetable farm (Sand Valley Experimental
Station) Ismailia Governorate, Egypt during the two successive fall seasons of 2020 and 2021 to study
the effect of transplanting date on vegetative growth, leaf pigments and productivity of five
cauliflower hybrids under sandy soil conditions. This experiment was include 10 treatments, which
were the combinations between two transplanting dates (transplanting in 1st August and transplanting
in 1st September) and five cauliflower hybrids (Barkha, Solid Snow, Mexico, Fargo and Raoul). These
treatments were arranged in a split plot design with three replications. Transplanting dates were
randomly distributed in the main plots, while the cauliflower hybrids were randomly arranged in the
sub-plots. The most important results were summarized as follows: The interaction between
transplanting date in 1st Sept. and Fargo hybrid recorded the maximum values of plant height, number
of leaves lant, leaf length, leaf width and leaf area, whereas the interaction between transplanting in
1
stAugust and Barkha hybrid gave the highest concentrations of chlorophyll a, b, (a+b) and
carotenoides in leaf tissues of cauliflower in both seasons. The interaction between transplanting date
in 1st Sept and Mexico hybrid gave he highest values of total yield/faddan with no significant
differences with the interaction between transplanting in 1st Sept. and Fargo hybrid in the 1st season.
However, the interaction between transplanting in 1st Sept, and Raoul hybrid significantly increased N,
P and K contents in curd in both seasons.
Key wards: Cauliflower, transplanting date, hybrids, leaf pigments, yield.
