Abstract
The objective of the present research was to study the response of the peach cultivars 'Spring Time' and 'Red Haven' to nitrogen, phosphorus, potassium fertilisation and manure. The following fertiliser combinations were used: control (no fertilisation), N, P, K, NP, NK, PK, NPK, cattle manure, N+manure, P+manure, K+manure, NP+manure, NK+manure, PK+manure, NPK+manure. The research was conducted during a period of 10 years (from the 5 th to the 14 th year of the productive life of the peach trees). Application of N plus manure to peach trees of the cv. 'Spring Time' resulted in the highest fruit yield. Total soluble solids content (%) of fruits of the cv. 'Spring Time' did not significantly alter in comparison to the control for all the fertiliser combinations used. The lowest yield of trees of the cv. 'Red Haven' was recorded in the treatments P, PK, and the control. The highest percentage of split pits of fruits of the cv. 'Red Haven' was recorded in the control, while the lowest in the NK, and PK+manure treatment in comparison to all the others. The highest percentage of incomplete fertilised fruits was recorded in the PK and manure treatments in comparison to all the others. Trees of the cv. 'Red Haven' fertilised with P, K, and PK begun to produce diminished yields from the 11 th year. For both cvs., at the age of 15, trees fertilised with P, K, PK and the control had finished their economic cycle as yield decreased to very low levels.
