Abstract: 2006–2007 m. Lietuvos žem s ukio universiteto Bandymu stotyje atlikti bandymai, kuriuose tirta ivairiu azoto normu itaka žieminiu kvieciu veisliu vystymuisi, fotosintetz s produktyvumui bei grudu derliui. Buvo atlikti dvieju lietuvišku žieminiu kvieciu veisliu tyrimai: labai geru kepimo savybiu ‘Ada’ ir patenkinamu kepimo savybiu ‘Seda’. Nustatyta, kad didesn s azoto trašu normos teigiamai veik balansa tarp augimo ir vystymosi procesu bei abieju veisliu fotosintetini produktyvuma. BBCH 34-39 etape ‘Ada’ veisl s kvieciu fotosintetinis produktyvumas buvo 43% didesnis trešiant N150, lyginant su kontroliniu variantu (N90). ‘Seda’ veisl s kvieciams azoto trašos tokios didel s itakos netur jo. Tirtu veisliu grudu derlingumas yra susijes su azoto trašu normomis ir augalu fotosintez s produktyvumu. Žieminiai kvieciai, azotas, fotosintez s produktyvumas.2006–2007 m.

The experiments were performed in the Experimental station of the Lithuanian University of Agriculture during 2006– 2007. The influence of nitrogen rates on winter wheat development, photosynthetic productivity and grain harvest was evaluated. The tests were performed with the following two varieties of Lithuanian winter wheat: ‘Ada’, having very good baking peculiarities, and ‘Seda’, having satisfactory baking peculiarities. It was established, that higher rates of nitrogenous fertilizers positively affected the balance between growth and development and the photosynthetic productivity of both species. In the BBCH 34–39 stage (stem elongation), photosynthetic productivity of wheat variety ‘Ada’ was by 43 % higher, when fertilizing with N150, in comparison with reference treatment (N90). Meanwhile, wheat variety ‘Seda’ was influenced by nitrogenous fertilizers not in such a great extent. Grain harvests in the cultivated species interrelate with the rates of nitrogenous fertilizers and photosynthetic productivity
