Peltojen viljavuuden kehitys Pohjanmaan ja Hämeen luomutiloilla
(MTT, 2009)
Suomessa oli vuonna 2007 luomuviljelyssä 5,9 % peltoalasta. Luomussa tärkeitä fosforin lähteitä ovat karjanlanta ja maan omat fosforivarat. Kasvinviljelyyn suuntautuneilla luomutiloilla lannan saatavuus saattaa muodostua ...
Nitrogen dynamics and nitrogen use efficiency of old and modern oats
(MTT, 2004)
Nitrogen (N) is one of the most important nutrients in crop production. The loss of nitrogen causes environmental pollution as well as economic losses. Therefore, cereal cultivars with more efficient N use are of special ...
Controlling perennial weeds in organically grown oats
(MTT, 2004)
Perennial weeds are an increasing problem in Finland, particularly in organic farming. Mechanical control by hoeing, stubble cultivation and bare fallowing provides some options for managing these weeds. Mechanical control ...
Trends of nitrogen use of oat cultivars from 1902 to 2002 in Finland
(MTT, 2004)
Plant breeding has improved grain yields of oats in northern growing conditions (Rekunen 1988, Slafer &Peltonen-Sainio 2001).One main contributor to increased yields is harvest index (HI). Cultivars have higher HI and ...
Apical development of oat
(MTT, 2004)
Development of cereal plants progress through set of orderly timed development phases. Rate and timing of these phases and single growth stages are strongly controlled by day length, accumulated temperature and genotype. ...
Radiation use efficiency of modern and old oat cultivars in Finland
(MTT, 2004)
Finnish plant breeding of oats has focused on improving stability as well as productivity in northern growing conditions. Breeding for short stature and early maturing oat lines has increased harvest index (HI) close to ...
Growth and architecture of dwarf, semidwarf and tall oat lines under northern latitudes
(MTT, 2004)
The Finnish particularly short growing season with frequently occurring fluctuations in climate affects crop growth and yield formation and especially quality severely. Dwarfing genes have been effective sources for lodging ...
Dw6 dwarfing gene enhances shoot elongation of CCC treated plants
(MTT, 2004)
Dwarf oat cultivars are often stated to be insensitive to antigibberellins. In some cases antigibberellins have, however, even enhanced stem elongation in dwarf oat. Antigibberellin chlormequat chloride (CCC) and an ...
Duration of apical development phases and their coincidence with growth rate in oat grown at high latitudes
(MTT, 2004)
The growth cycle of oat can be divided into different main phases. Duration of these are dependent on genotype and environment. In this study, apical development and growth of 20 oat cultivars and lines released since ...
Factors affecting the concentration of avenanthramides in oats
(MTT, 2004)
The main objective of this study was to get insight on quality related components affecting the end-use properties of different oat cultivars. Combining the harvest data to chemical analyses such as beta-glucan, cadmium ...
