Competition between Winter Wheat and Cornflower (Centaurea cyanus L.) Resistant or Susceptible to Herbicides under Varying Environmental Conditions in Poland

open access: yesAgronomy, 2022
Competitive ability of cereals against segetal weeds depends among other things, on soil properties and the weather. Concerning cornflower (Centaurea cyanus L.), this issue is poorly recognized, as there are no reports on the impact of environmental ...

The Online Reservation Problem

open access: yesAlgorithms, 2020
Many sharing-economy platforms operate as follows. Owners list the availability of resources, prices, and contract-length limits. Customers propose contract start times and lengths. The owners decide immediately whether to accept or decline each proposal,

On-line computation and maximum-weighted hereditary subgraph problems [PDF]

open access: yesYugoslav Journal of Operations Research, 2011
In this paper1 we study the on-line version of maximum-weighted hereditary subgraph problems. In our on-line model, the final instance (a graph with n vertices) is revealed in t clusters, 2 ≤ t ≤ n .

Better Land and Nitrogen Complementarity for Green Forage Than for Silage in Barley–Field Bean Intercropping

open access: yesAgronomy, 2023
Biomass and nitrogen (N) accumulation in intercrops for forage production under different fertilizations have seldom been assessed and, more occasionally, have been investigated at different stages. The biomass and N contents of barley (Hordeum vulgare L.
