RELATIONS BETWEEN DENSITY, YIELD AND PROFITABILITY OF APPLE ORCHARDS |
| Authors: | P. Vig, E. Kállay |
| Abstract:
The ratio of higher density in apple orchards has considerably increased in Hungary. Experimental plantations have been established for the different rootstocks, varieties and ecological factors. The productive crown volume of the 5 planting systems greatly differ. The best yield was obtained from spindle trees inspite of the higher specific productivity of slender-spindle trees having less crown volume per tree and per ha. The costs of establishment conserning the density of 1 250 trees/ha are double of the one with 317 trees/ha. Average farm price and profit in relation to the skin-colouring and harvest injuries are the most favourable in slender-spindle plantations. Among the orchards of different density slender-spindle of 1 250 trees/ha has the best profit index followed by the spindle trees. The efficiency of hand picking - having great importance for the large-scale production of Hungary - is also outstanding in slender-spindle orchards. The experimental data proof that the density higher than 1 250 trees/ha is not generaly reasonable under the Hungarian conditions. | |
