Abstract
Use of biostimulants in commercial horticulture has been promoted as one of key approaches for sustainable food production.
Biostimulants are claimed to have the potential to reduce resource inputs – such as water and mineral fertilisers – and increase tolerance to abiotic stresses.
We investigated the effect of several seaweed-derived biostimulants applied to strawberry and raspberry crops grown under fully fertigated commercial conditions and under reduced fertigation.
Fruit yield, fruit quality, plant biomass, photosynthetic parameters, stem water potential, stem/leaf growth and intrinsic water use efficiency (delta 13C isotope) were measured.
The tested biostimulants did not have any significant effects on measured plant growth/development parameters.
There appeared to be a slight increase in gas exchange performance in strawberry treated with ASCO-N2, but those did not translate into yield benefits.
Reduced fertigation in strawberry by ca 50% (vs. current commercial practice) did not significantly reduce fruit yield indicating that improving fertigation use efficiency is possible.
