Two experiments were conducted to study the effect of two seedling dates
and foliar application of Algae extract, Moringa extract, fulvic acid and Mepiquat
chloride on some growth and fruit productivity of cucumber plants (Cucumis
sativus L.) cv. barracuda at private farm in "Awlad Al-Sharif" village in Dirout
city, Assiut Governorate, Egypt. Two experiments were conducted during the
successive seasons of 2019/2020 and 2020/2021 inside greenhouses. Spraying
cucumber plants was done with two concentrations three weeks after seedling two
times at 15 day intervals each. The experiment was laid out in Randomized
Complete Block Design (RCBD) with a split-plot arrangement in three
replications. Seedling dates were assigned in the main plot and foliar application
(with two concentrations) was arranged in sub-plot.
Results indicate that planting cucumber seedlings early in November under
protected agricultural systems leads to significant effect on all traits under the
study except fruit length and fruit diameter compared to the second seeding date,
respectively. All foliar application treatments and their interactions gave highly
response in all traits especially the high concentration of algae (3 g/m3) and fulvic
(3 g/m3) compared with other treatments.
