This investigation was carried out during both 2013 and 2014 seasons to cover the influence of the two
investigated factors i.e., rootstock citrus type (sour orange and Volkamer lemon) and mineral fertilization and
their possible combinations. The influence was evaluated through the response of some vegetative growth of
"Valencia" orange cultivar. The specific effect of rootstock type on some vegetative growth, data revealed that,
Valencia orange budded on Volkamer lemon rootstock was better than the other investigated rootstock (sour
orange) in this respect. Also, fertilizer with soil application of mixed minerals ores at 150 g/ plant + ¼ NPK
application of control was superior in this respect where it was able to increase significantly vegetative growth
as compared with the other different investigated fertilization especially NPK only (control) during both seasons
of study. Concerning the interaction effect of the two investigated factors i.e., rootstock type and different
mineral fertilization on vegetative growth of "Valencia" orange transplants, data show the highest vegetative
growth were obtained with the combination between "Valencia" orange transplants budded on Volkamer lemon
rootstock and fertilized with soil application of mixed minerals ores at 150 g/ plant + ¼ NPK application of
control.
