A digestibility trial was conducted to examine the effect of feeding rate on dry matter, gross energy, crude protein and phosphorus digestibility in Atlantic salmon (Salmo salar). Duplicate groups of fish were fed 0.25, 0.5, 0.75, 1.0, 1.25 and 1.9% BW/day. The faeces were collected by Guelph-type collectors for five successive days. Dry matter, protein and phosphorus digestibility’s were all s...

The aim of the experiment was to determine correlations between tuber yield and components measure direct indirect effects on potato genotypes. conducted using eleven genotypes with one standard check variety (Belete) a local at Kulumsa Agricultural Research Center, Bekoji sub-station during 2020-2021. Data were collected for yield, dry matter content (%), plant height (cm), stem number, specif...

The cultivar selection and nitrogen (N) fertilization are key management factors to improve potato yield. aim of the present study was evaluate ecophysiological determinants biomass tuber yield in genotypes response N availability under field conditions. Experiments 1 2 were carried out a volcanic soil southern Chile during 2021–2022 season. Treatments applied factorial combination (i) fifteen ...

introduction: increasing crop competitive ability is an important part of integrated weed management (iwm). in this regard, identifying weeds reaction to soil fertility status for developing fertilizing methods, as components of iwm programs, is a necessity. materials and methods: in order to evaluate the growth characteristics of purple nutsedge under the conditions of interference with onion,...

Th e study was focused on evaluation of SUBSTOR – Potato model and its utilization in potato growing management in the Czech Republic. Th e experimental fi eld used for the model evaluation was located in Žabčice – South Moravia region with altitude of 179 meters above the sea level. Tuber yield served as reference for the model evaluation. Nine years experimental data set (1994 – 2002) was use...
