CORRELATIONS BETWEEN SOME PHYSIOLOGICAL PROCESSES OF MAIZE HYBRIDS WITH MINERVA AND DANUBIU INFLUENCE ON YIELDAND QUALITY OF GRAIN

Diana Radulescu, Stefania Luiza Tanasie, Florin Dumitru

Abstract


The paper presents originality because in Oltenia, in general, were not conducted studies of physiological processes determined in different environmental conditions or water deficit years and years normal in terms of climate, the maize crop. There were two hybrids in the study Danubiu and Minerva, where they were executed correlations showing the indispensable link between the conduct physiological processes during vegetation and their influence on the quality and quantity of grain corn harvest.
Experiments were located in Olt, respectively in common Dobroteasa taking soil samples. The combined influence of hybrid technology and culture (applying proper irrigation and fertilizer dosing) causes changes in key physiological processes that can lead to optimization of production technologies in order to obtain maximum dose of fertilizer applied rationally.
Hybrids and Danubiu Minerva in the study were grown under the same conditions behaved differently in terms of technology, culture, values recorded in being physiologically different each using the right level of fertilizer.
They studied the effects of simultaneous application of irrigation with varying doses of fertilizers.
