Evaluation and selection of alfalfa genotypes for tolerance to aluminium toxic stress.

Alfalfa is one of the most important and the most cultivated crop due to its high nutritive quality and yield, but adaptation of alfalfa genotypes differ in terms of mobile aluminium stress in the soil. The aim of this study was to evaluate the tolerance to mobile Al concentrations in the laboratory and in the naturally acidic soil and select the promising genotypes based on agro-biological traits. In 2019, a laboratory experiment was conducted at the Institute of Agriculture of LAMMC.

Soil Seed Banks and Their Relation to Soil Properties in Hilly Landscapes.

For the prevention of hilly soils from erosion, a smart selection of crop rotations is very important. The aim of this study was to investigate the influence of different agrophytocenoses on seed numbers in the soil runoff sediments and soil seed banks' relations to soil properties in hilly landscapes. This study analyzes long-term monitoring data from three different agrophytocenoses (permanent grassland, cereal-grass crop rotation and crop rotation with a row crop) set up on slopes of 9-11° steepness with collectors for soil and water installed.

The Impact of Nitrogen on the Yield Formation of Wall: Efficiency and Assessment of Energy Parameters.

With the increasing importance of energy crops, research on potential energy crops is carried out to identify plant species with high productivity and energy value. The field experiment with the new promising energy crop, (wormwood), was executed at the Vėžaičiai Branch of the LAMMC. The soil site was naturally acidic (pH 4.

Seed Bank Community under Different-Intensity Agrophytocenoses on Hilly Terrain in Lithuania.

On the summit of a hill with a lack of humidity, and in usually stronger eroded midslope parts, crops thin out. Changing ecological conditions change the soil seed bank as well. The aim of this study was to examine changes in the seed bank size and number of species and the influence of seed surface characteristics on their spread in different-intensity agrophytocenoses under hilly relief conditions.

Soil Seed Bank in a Pre-Erosion Cereal-Grass Crop Rotation.

Soil erosion by water is a serious environmental problem. It is very important to form agrophytocenosis, which is productive on hilly terrain and could effectively protect the soil from erosion. The aim of the study was to examine the impact of a hilly relief on the changes of seeds in a soil of pre-erosion cereal-grass crop rotation.
