Impact of seedling dates and different foliar applications on growth and productivity of cucumber hybrids (Barracuda.) under protected agricultural systems [electronic resource]

Includes bibliographic reference

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.
