Effect of the potassium and magnesium nutrition on potato (Solanum tuberosum L.) tuber quality and plant development
(2018-10-17)Knowledge regarding the importance of potassium (K) and magnesium (Mg) for potato plant development and tuber quality is limited. K and Mg are nutrients, besides other crucial roles, for photosynthesis and the partitioning ... -
Effect of plant and animal functional traits on nutrient cycling in low-input pastures
(2018-09-05)Excrements of grazing animals play a key role for nutrient cycling in grazed grasslands. So far, most studies on nutrient cycling in pasture systems were performed using simulated excrement patches under simulated grazing ... -
Assessment of genetic and nutritional diversity, and salinity tolerance of Kenyan guava (Psidium guajava L.): an underutilized naturalized fruit species
(2018-08-07)Common guava (Psidium guajava L.) fruit has a significant nutritional and medicinal potential besides its economic importance, yet is still underutilized in terms of production and consumption. The current global guava ... -
Site-specific adaptation by natural selection. A case study with lentil.
(2018-04-10)In the context of conservation and use of plant genetic resources, both storage in gene banks (ex situ) and safeguard on-farm (in situ) are important concepts. Increasingly attention focuses on the on-farm management of ... -
Root exudation pattern of sugar beet (Beta vulgaris L.) as influenced by light intensity and P deficiency
(2016-07-28)Sugar beet is known as a P uptake efficient plant species due to its ability for increasing P availability in soil. This is done by changing rhizosphere chemistry through exudation of e.g. citric, malic, oxalic, citramalic ... -
Intensifying rice-fallow systems in Southeast and South Asia with grain legumes and/or dry season crops: analysis using field experiment and simulation
(2016-07-26)In most Southeast and South Asia countries, lowland rice is particularly grown as a single crop at the wet season, followed by dry season crops or fallow at dry season and characterized under rainfed condition. The inclusion ... -
Nitrogen Efficiency of Winter Oilseed Rape and its Prediction by Hyperspectral Canopy Reflectance and Electrical Capacitance
(2016-07-01)Oilseed rape is the third most important oil crop worldwide. Under many conditions it is characterised by relatively low nitrogen efficiency. In Germany a nitrogen supply of 240 kg N ha 1 is aimed at which derives from ... -
Measuring and modelling the dynamics of carbon and nitrogen mineralization from diverse plant residues in soil – plant systems
(2016-06-29)Nutrient cycling in the soil – plant ecosystem is an essential component of sustainable productive agricultural activities. Although during the last 20 years inorganic fertilizer have played a dominant role of nutrient ... -
Characterization of α-amylase in wheat and maize
(2016-04-11)Alpha-amylase is a starch-hydrolyzing enzyme and its characterization is an important quality parameter in cereal grains. In breadmaking, adequate α-amylase activity is required to produce bread of good quality. High ... -
Nitrogen efficiency in semi-dwarf and normal hybrids of oilseed rape
(2015-06-19)The cultivation of winter oilseed rape is characterized by high rates of nitrogen fertilization. This can cause large nitrogen surpluses after seed harvest of oilseed rape. Most of the rapeseed oil is used for the production ... -
Nitrous oxide from fungal denitrification - Pure culture and soil studies using stable isotope and microbial inhibitor approaches
(2014-12-17)The trace gas nitrous oxide (N2O) contributes to climate change as well as to the depletion of the ozone layer in the stratosphere. Agricultural soils account for about 70% of the high anthropogenic N2O ... -
Genetic mapping of QTL controlling salt tolerance and glucosinolates in Brassica napus and Brassica oleracea
(2014-12-05)Brassica species are of great importance for human food and animal feed supply. Brassica napus occupies the second position among the oilseed crops behind soybean. Brassica oleracea includes numerous species of vegetables. ... -
Genetische Analysen für eine markergestützte Verbesserung der Trockenstresstoleranz von Winterackerbohnen
(2014-08-04)In this analysis, aiming to prepare for marker-assisted selection of drought tolerance in autumn sown faba bean (Vicia faba L.), 196 winter-type and four spring-type inbred lines were genotyped. Physiological traits such ... -
Sustainable grassland herbage production under drought stress - the role of plant species number and functional group composition
(2013-06-14)Producing grassland herbage with high yield and good nutritive value is a prerequisite of an efficient ruminant livestock production. Due to climate change, precipitation patterns are expected to vary and the frequency of ... -
The effect of grassland botanical composition and (co-) grazing cattle and sheep on herbage production and sward nutrient utilisation
(2011-09-13)Plant diversity in grassland ecosystems has recently gained increasing interest, as plant diversity has often been found to be related to improved ecosystem functioning. So far, studies of ...
