STUDIES ON SYSTEM INFLUENCE IRRIGATED AND NON IRRIGATED LAND MANAGING DIFFERENT DOSES OF NP, ON THE EXTENT OF ACCOMPLISHMENTS PHYSIOLOGICAL HYBRID MAIZE OITUZ

The present work tries to establish the role of irrigation and applying variable doses of Nitrogen and Phosphorous, it also tries to ground, from the physiological point of view, the contribution of each factor in achieving high quantitative and qualitative productions. Within the experimental filed an important moment was followed, respective the 8 full-grown leaves phase, and lab tests were kept in order to perform physiological determinations. After lab determinations of physiological processes which took place in the case of this hybrid in two different systems and after applying different doses of fertilizers, the results were also graphically represented.
