Genetic variability of yield and its components in spring vetch cultivars
(Estonian Grassland Soc-Egs, Tartu, 2005)
Breeding of both winter and spring common vetch and creation of new cultivars are based upon a rather wide variability of morphological traits within the species of Picia sativa L. A three-year (2002-2004) small-plot trial ...
Weed populations in maize as affected by crop rotation and primary soil tillage
(Journal of Plant Diseases & Proctection, Supplement, 2008)
A seven year field study was conducted in south-western Slovakia to investigate the effects of different soil tillage intensities and crop rotation patterns on weed density, weed species composition and diversity, and weed ...
The influence of an ecological and a low input system on weed density, weed diversity and weed competition in spring barley
(Journal of Plant Diseases & Proctection, Supplement, 2008)
The field trial was carried out over the period 2000-2005 at the experimental station of the Research Institute of Plant Production in Western Slovakia. The purpose of the study was to investigate weed density and diversity ...
Variability of characteristics of garlic (Allium sativum L.) ecotypes
(Int Soc Horticultural Science, Leuven 1, 2002)
We studied the variability of characteristics of ecotypes of winter and spring garlic collected in the Vojvodina Province, the main production region in Yugoslavia. The ecotypes were analyzed for variability of nine ...
Ecological aspects of in vitro wheat herbicide tolerance testing
(Novi Sad : University of Novi Sad, Institute for Food Technology, 2007)
To avoid soil pollution caused by field trials for herbicide tolerance of wheat genotypes, an alternative in vitro lest was created and analyzed in this study. For validation of in vitro results, a comparative in situ test ...
Organization of wheat genetic resources in collections
(Hat Yai (Thailand) : Prince of Songkhla University, Faculty of Natural Resources, 2007)
In this paper we outlined our approach in organizing wheat germplasm, where the breeders evaluate and use the collections. Wheat germplasm was organized in three levels. World collection (whole collection) comprises 2,576 ...
Use of additive-dominant model in genetic analysis of some quantitative caracteristics in sunflower
(European Association for Research on Plant Breeding, 2006)
A simple link between the expected means of quantitative traits of different generations (progenies) can be established if the mean values are dependant exclusively on additive and dominant gene effects. Th is study aims ...
Uslovi proizvodnje strnih žita u 2001/02. godini
(Novi Sad : Institut za ratarstvo i povrtarstvoNovi Sad : Semenarstvo, 2002)
Završni period vegetacije strnih žita 2001/02. ne obećava visoku proizvodnju. Naprotiv, kao i tokom većeg dela dosadašnjeg toka, i u završnom periodu vladaju veoma nepovoljni vremenski uslovi. Suša i nešto više temperature ...
Adaptacija na pojavu bolesti izazvanih klimatskim promenama i procene rizika / Adaptation to Diseases Caused by Climatic Changes and Evaluation of Associated Risks
(Novi Sad : Univerzitet u Novom Sadu, Prirodno-matematički fakultet, 2009)
Evidento je da se tokom poslednjih godina dešavaju određene klimatske promene. Jedna od njih je globalno otopljavanje. Klimatske promene se najviše odražavaju na poljoprivredu, a posebno imaju uticaj na pojavu bolesti i ...
Efekat kasnog tretiranja ozime pšenice fungicidom na razvoj Puccinia triticina i prinos genotipova 2004. godine / Effect of the late treatment by fungicide on leaf rust development of Puccinia triticina and yield of the winter wheat genotypes in 2004.
(Beograd : Društvo za zaštitu bilja Srbije, 2004)
U ogledu postavljenom kod Rimskih Šančeva 2003. godine, ispitivano je dvanaest genotipova ozime pšenice. Setva je obavljena 22.10.2003. a žetva 06.07.2004. Parcelice (7m 2) tretirane (T) su preparatom Folicur EC 250 (250 ...
