The soil application of a plant‐derived protein hydrolysate speeds up selectively the ripening‐specific processes in table grape

Physiologia Plantarum, Volume 177, Issue 1, January/February 2025.
Abstract Plant‐derived biostimulants have gained attention in agricultural practices for their potential to enhance crop quality and resilience. In this study, we investigated the effects of applying a maize gluten‐derived protein hydrolysate at the soil level in vineyards on berry quality in a table grape variety, the Black Magic early table grapevine,

Minimal Water Consumption for a Crop Fertirrigation Model

2024 European Control Conference (ECC)
In this work, we consider a simplified model of crop fertirrigation as a non-autonomous controlled system, with soil moisture, nitrogen content, and biomass as state variables and the delivered water flow rate as input. We study the problem of minimizing the total water quantity delivered during the agricultural season under the constraints that the ...
