Abstract
The present invention refers to a composition based on algal and/or plant extracts and its use in agriculture to improve water use efficiency and/or water productivity in plants and/or agricultural water management thus resulting in increased yield of crop plants per unit water used.
Claims17
A method for improving water use efficiency and/or water productivity in plants and/or agricultural water management, comprising the step of feeding plants an effective amount of a composition comprising at least one algal extract and at least one plant extract, wherein the feeding step occurs by administering the composition through the soil, and wherein said plants are in a non-drought condition, wherein the non-drought condition corresponds:
- 1) to a value of leaf stomatal conductance level above 0.15 mol H2O m−2s−1, as measured through porometer Licor gas-exchange system,
- and/or to a value of soil water content ranging from −10 kPa to −60 kPa, wherein said soil water content is measured by using tensiometers wherein the composition increases plants at least one of Green Index, Digital biovolume, Humid Index, Stomatal Conductance and yield in comparison to plants being fully watered (100% watered) or 70% watered (reduced watered) untreated with the extracts.
