Marker-trait-sensor association in a multi-parent advanced generation intercross (MAGIC) population in barley (Hordeum vulgare ssp. vulgare)
(2013-11-21)
The objective of the present study was to identify quantitative trait loci (QTL) for yield, yield components and water content in leaves as measured with the THz-sensor in a MAGIC population derived from eight different ......

Implications of topography and agronomic practices for soil biogeochemical and microbiological properties in Upper Eastern Ghana hilly farmland
(2022-02-10)
While topography can infer erosion potential, implementation of convention practices can trigger accelerated erosion, and both pose major threats to soil abiotic properties and microbiota. The majority of farmlands in the ...
Characterization of mechanisms of resistance in Spodoptera frugiperda to synthetic insecticides and insecticidal proteins
(2021-03-18)
Fall armyworm (FAW), Spodoptera frugiperda(J.E. Smith), is a major lepidopteran pest of maize in the American continent butitis now present in 107 countries worldwide. The control of FAW has relied mainly on the ...
Effects of heat and drought stress on cereal crops across spatial scales
(2017-02-10)
The production of cereal crops is increasingly influenced by heat and drought stress. Despite the typical small-scale sub-regional variability of these stresses, impacts on yields are also of concern at larger regional to ...
Zur tierökologischen Bedeutung der Elsbeere (Sorbus torminalis L. CRANTZ)
(2018-06-14)
Mit der vorliegenden Dissertation soll das ökologische Beziehungsgeflecht der Elsbeere (Sorbus torminalis) erfasst werden, einer in Deutschland seltenen, in zerstreuten, kleinen Populationen vorkommenden Baumart (Fam. ......
The Significance of the Wild Service Tree (Sorbus torminalis L. Crantz) in Regard to Animal Ecology
This thesis aims to document the ecological web of the wild service tree (Sorbus torminalis) – a ......

Deciphering the role of apoplastic root barriers in the interaction between sedentary nematodes and Arabidopsis
(2018-12-13)
The plant-parasitic nematode species Heterodera schachtii and Meloidogyne incognita infect economically important crop plants in the entire world. Their infection causes yield losses, but effective and environmentally ...
Proline mediated drought tolerance of selected barley (Hordeum vulgare L.) introgression lines and characterization of in vivo spike development
(2022-08-31)
The potential yield of barley is likely to decrease in the future due to the prevalence of drought stress in many world regions. In our study, drought stress affected phenology, biomass and other growth traits, and seed ......
Das Ertragspotenzial von Gerste wird in Zukunft wahrscheinlich abnehmen, da in vielen Regionen der Welt Trockenstress vorherrscht. In unserer Studie wirkte sich der Trockenstress auf die Phänologie, die Biomasse und andere ......

Interactive tillage & crop residue management effects on soil properties, crop nutrient uptake & yield in different weathered soils of West Africa: measurements, modelling & scenario simulations
(2020-04-22)
Sustainable crop production intensification in West Africa is hampered by constraints such as soil degradation, mainly due to excessive mining of soil nutrients, topsoil loss by surface runoff, and climatic factors like ...
Studies on the effect of exogenous amino acid application on nematodes
(2020-03-02)
Plant parasitic nematodes are considered as key pathogens in agricultural crop production. They cause substantial yield losses in numerous crops and across all climatic regions worldwide. Antagonistic effects on various ......
Phosphorus forms in fertilized arable soil profiles and related 33P uptake
(2019-09-13)
Arable soils usually store several thousand kg phosphorus (P) per ha, thus far exceeding the recommended P fertilizer dose to sustain crop yields. However, the soil profile is frequently not considered in fertilizer ...
