INFLUENCE OF SOIL TYPE AND NITROGEN FERTILIZATION SUGAR BEET YIELD AND QUALITY [PDF]
Poljoprivreda, 2011 In 2009 and 2010 we studied effect of nitrogen fertilization on the yield values on two soil types of different physical and chemical properties. Nitrogen was applied in autumn as a pre-sowing treatment on the basis of Nmin supplies in the soil, and as a

Nitrogen top-dressing fertilization of maize cultivated in single and twin-row systems1
, 2021 The aim of this study was to evaluate the effects of cropping systems (single and twin-rows) and N fertilizer rates in the second top-dressing on the agronomic performance and relative economic returns of maize. The experiment was conducted in a randomized block design, with subplots and three repetitions.

The value of mid-season top-dressings of nitrogen fertilizer for main-crop potatoes [PDF]
The Journal of Agricultural Science, 1957 Twenty-one field experiments were carried out from 1953 to 1955 on main-crop potatoes to compare dressings of nitrogen applied wholly to the seedbed (as ammonium sulphate), with equivalent dressings applied partly to the seedbed (as ammonium sulphate) and partly as a top-dressing (of ‘Nitro-Chalk’) just before the final ridges were set up.

Biocompatible but Antibacterial Mechanism of Graphene Oxide for Sustainable Antibiotics
Advanced Functional Materials, EarlyView.Graphene oxide (GO) exhibits selective antibacterial activity through specific interactions between its oxygen functional groups and bacterial membrane phospholipid POPG, causing membrane destabilization while maintaining biocompatibility. Model membrane studies and infected wound models in mice and pigs demonstrate effective bacterial suppression and ...
