INTERACTION BETWEEN MAIZE AND SOYABEAN IN INTERCROPPING / INTERAKCIJA IZMEĐU KUKURUZA I SOJE U ZDRUŽENOM USEVU
(Ekološki pokret grada Novog Sada, 2002)
Intercropping two or more crops under similar microenvironmental conditions can increase the agricultural productivity. A field study was conducted in two-year period 1998-1999 at experimental field Radmilovac of Faculty ...
Повећање производног потенцијала агроекосистема у систему одрживе пољопривреде
(Ekološki pokret grada Novog Sada, 2002)
The strategic cornerstones of enhanced productivity are likely to be the following: increasing genetic potentials of crops and livestock, reducing biotic losses associated with pests, pathogens and weeds, extending the ...
Screen printed barium titanate thick films prepared from mechanically activated powders
(Trans Tech Publications Ltd, Durnten-Zurich, 2002)
Barium titanate thick films were prepared from mechanically activated powders based on BaCO3 and TiO2. The thick films were screen-printed on alumina substrates electroded with Ag/Pd. The BT films were sintered at 850 ...
Phase transformations and thermal effects of mechanically activated BaCO3 -TiO2 system
(Ferroelectrics, 2002)
Phase transformations and thermal effects of BaTiO 3 ceramics due to influence of mechanical activation were investigated. Equimolar mixture of BaCO 3 and TiO 2 powders was activated in high energy vibromill for various ...
New digital method of microstructural characterization of sintered materials
(Serbian Acad Sciences Arts, Belgrade, 2002)
Since a lot of physical properties of novel materials are determined by their microstructure it is very important to predict and control materials microstructure and its evolution, both in technological process of material ...

Potato Virus Y (PVY) on pepper in Serbia
(Int Soc Horticultural Science, Leuven 1, 2002)
During 1997, samples of plants showing symptoms of a viral disease were collected from thirteen pepper growing areas. On some plants characteristic symptoms of Potato Virus Y (PVY) infection were observed. Pepper samples ...
Inheritance of yield components in diallel crossing of divergent genotypes (Solanum melongena L.)
(Acta Horticulturae, 2002)
The aim of this study was to determine the mode of inheritance, the combining ability and the components of genetic variance for fruit weight and fruit number per plant in five divergent eggplant genotypes. The investigation ...
Influence of some soil characteristics on heavy metal content in Hypericum perforatum L. and Achillea millefolium L.
(Acta Horticulturae, 2002)
Hypericum perforatum L. and Achillea millefolium L. are plants which can be characterized as heavy metal accumulators. Including relating soils samples differing in pH reaction, 14 samples of St. John's wort and 9 samples ...
Microcalorimetry in the identification and characterization of the most reactive active sites of heterogeneous catalysts
(Springer/Plenum Publishers, New York, 2002)
The microcalorimetric technique has been applied to investigate the strongest active sites of zeolites, heteropolyacids and perovskites. The differential heats of adsorption of carbon monoxide, ammonia and oxygen were ...
