THE INFLUENCE OF MANAGEMENT AND FERTILIZATION SYSTEMS ON TREE GROWING AND FRUIT SETTING IN A PEACH TREE ORCHARD

Soil management systems (SMS) have a great importance to achieve high quality, fruit and yields with low pollution.
This is especially the case for peach culture which has a stronger response to these technologies.
For this reason some investigations were carried out at the R.S.F.G. Constanta on a carbonated chernozem showing high fertility.
The following layout was studied according to the subplot method in four replications and five trees were used within a replicate plot: SMS between tree rows (factor A with 2 graduations), SMS on the tree rows (factor B with 2 graduations) and N amount (kg active substance/ha) with 3 graduations.
After five years of study, on average, clean cultivation between tree rows versus the mowed sod strips deter¬mined: an increase in the tree root number by 11%, a significant increase in tree trunk cross sectional area (TTCSA) by 4%, in fruit weight by 15%, in fruit number per tree by 30% and in fruit yield by 55%.
