Effect of the rate and ratio of NPK mineral elements on the carotenoid content of maize grain


, : Effect of the rate and ratio of NPK mineral elements on the carotenoid content of maize grain. Savremena Poljoprivreda 20(9): 35-39

Applied N increased the carotenoid content of maize grain by increasing the production of amino acids which acted as precursors in carotenoid biosynthesis; applied P played an important role in regulating the ATP/NADP-H2 conversion. The application of NPK increased grain carotenoid content more than either element individually or applications of NP, NK or PK.
