Abstract

The recent dry years in Europe have illustrated the urgent need to secure agricultural yields. In order to achieve good plant growth without overusing resources such as water or fertilizer, the approach to the improvement of the soil could be a good alternative. Winter wheat is the most common cultivated crop in northern Germany. For this reason, a new organic soil amendment based on tree compartments and one with polymers for water retention were tested for their effectiveness in reducing effects of drought stress during three vegetation periods (2016-2018). It was examined whether their use can reduce or substitute irrigation and leads to better yields. The experiments were carried out in controlled nursery conditions with 8 replicates and under two irrigation regimes, well-watered with 64 l/m² in 4 month and controlled water restriction (9,6 l/m² in 4 month) during vegetative growth. Biometric plant parameters such as the SPAD (single-photon avalanche diode) value, plant height, over- and underground biomass and grain yield were used to compare the variants. Initially, both components were tested separately to be used in combination in the second and third year. When both amendments were used, results showed same plant heights, 10% more biomass and 25% more yield by water deficit compared to treatments without additives. The organic component promoted the chlorophyll value from 35 to 45. The experiments showed that this both soil amendments can lead to a grain yield of 70% compared to irrigated variants and to good wheat growth during drought.

    AB  - The recent dry years in Europe have illustrated the urgent need to secure agricultural yields. In order to achieve good plant growth without overusing resources such as water or fertilizer, the approach to the improvement of the soil could be a good alternative. Winter wheat is the most common cultivated crop in northern Germany. For this reason, a new organic soil amendment based on tree compartments and one with polymers for water retention were tested for their effectiveness in reducing effects of drought stress during three vegetation periods (2016-2018). It was examined whether their use can reduce or substitute irrigation and leads to better yields. The experiments were carried out in controlled nursery conditions with 8 replicates and under two irrigation regimes, well-watered with 64 l/m² in 4 month and controlled water restriction (9,6 l/m² in 4 month) during vegetative growth. Biometric plant parameters such as the SPAD (single-photon avalanche diode) value, plant height, over- and underground biomass and grain yield were used to compare the variants. Initially, both components were tested separately to be used in combination in the second and third year. When both amendments were used, results showed same plant heights, 10% more biomass and 25% more yield by water deficit compared to treatments without additives. The organic component promoted the chlorophyll value from 35 to 45. The experiments showed that this both soil amendments can lead to a grain yield of 70% compared to irrigated variants and to good wheat growth during drought.
