SUMMARY

This work was carried out in attempt to find out the best preparation formulas of horse manure and synthetic compost under condition familiar to Turkey. Experiments were conducted at the mushroom research facilities of the Yalova Atatürk Central Horticultural Research Institute between1992 and 1995.

The experiments were conducted as basic materials and wheat bran, cotton seed and sunflower meals, malt sprout chicken food, molasses ammonium nitrate and urea as activators were used. The nitrogen content of the starting mixture was brought to %2 in all applications.

The highest yield by using horse manure compost was obtained from the combinations of 1000 kg. of horse manure, 50 kg. of wheat bran, 3.1 kg. of ammonium sulphate, 1.5 kg. urea, 35 kg. of gypsum and 1000 kg. of horse manure, 40 kg. of chicken food or malt sprout, 7.5 kg. of urea, 35 kg of gypsum.
