Production of Table Potatoes in Europe - A Multinational Gross Margin Analysis AgEcon
Pedersen, Soren Marcus; Bizik, Jan; Costa, Luisa Dalla; Coutinho, Joao; Dolezal, Frantisek; Gluska, Anna.
This paper examines different cropping practices, cost structures and gross margins for conventional table potato cropping in 6 different regions within the European Union: Czech Republic, Denmark, Italy, Poland, Portugal and Slovakia. Findings from this study show that potato cropping practices varies significantly between the various countries with major differences in yield and costs. Italy and Denmark are the two regions with highest gross margins due to high yields and revenues. Poland is by far the largest potato producing country among the 6 countries. However, the production is primarily based on small scale farming with low yields and economic revenues.

Influence of temperate grass seed rotation systems on weed seed soil bank composition Rev. bras. sementes
Medeiros,Renato Borges; Steiner,Jeffrey J.
Due to changing cropping practices in perennial grass seed crops in western Oregon, USA, alternative rotation systems are being considered to reduce weed infestations. Information is generally lacking regarding the effects of alternative agronomic operations and herbicide inputs on soil weed seed bank composition during this transition. Six crop rotation systems were imposed in 1992 on a field that had historically produced monoculture perennial ryegrass (Lolium perenne L.) seeds. Each system plot was 20 x 30 m, arranged in a randomized complete block design, replicated four times. Twenty to thirty soil cores were sampled in June 1997 from each plot. The weed species composition of the cores was determined by successive greenhouse grow-out assays. In...
