Abstract

FELIX-LEYVA, Jesús Tomas et al. Hydric Stress in the Production of Grafted Cucumbers Grown on Soil and Substrate. Terra Latinoam [online]. 2024, vol.42, e1784.  Epub Mar 14, 2025. ISSN 2395-8030.  https://doi.org/10.28940/terra.v42i.1784.

The cucumber crop is affected by the volume of water supplied, which can decrease the architecture of the plant as well as the yield. Grafting can increase horticultural production due to its root vigor and explorative capacity. Therefore, a low-tech greenhouse experiment was set up at the facilities of the Universidad Autónoma Agraria Antonio Narro. In the spring-summer period, under a completely randomized design with a 2 x 2 x 2 factorial arrangement, obtaining eight treatments. The objective was to evaluate the effect of anchorage point (soil and substrate), grafting (with and without grafting) and irrigation volume (100% and 75%). Crop growth variables (plant height, basal diameter, number of leaves), yield variables (polar and equatorial diameter, number of fruits and yield), stomatal conductance and crop biomass were analyzed. The results showed an increase of 22.9% in growth and 56 % biomass variables with the graft grown on substrate, allowing plant energy savings and a tendency to be more efficient in water use. This indicates that grafting is a beneficial tool for improving yields, as well as being an environmentally friendly technology.

Keywords : biomass; cucumis sativus; irrigation deficit.
