Bu çalışma 1985-1990 yılları arasında Atatürk Bahçe Kültürleri Merkez Araştırma Enstitüsü mantar üretim tesisi araştırma odalarında yürütülmüştür. Çalışmada buğday saplı taze at gübresine ağırlığının %25 ve %50 oranında buğday sapı ilaveleri temel alınmış ve kompost yapımında en uygun azot oranını saptamak amacıyla kompost yığınlarının azot düzeyleri kuru madde esasına göre %1.5, %1.75, %2.0, %2.25 ve %2.5 oranlarına getirilmiştir. Azot düzeylerini istenilen oranlara getirmek için saf azot değerleri yönünden eşit miktarlarda amonyum nitrat ve üre ilave edilmiştir. Denemelerden elde edilen bulgulara göre en iyi sonuç kompost hazırlama başlangıç materyalinin azot düzeyi %2 oranına getirilen uygulamadan sağlanmıştır. Denemelerden elde edilen sonuçlara göre en yüksek verimin elde edildiği kompost formülü aşağıda verilmiştir. 1000 kg taze at gübresi (buğday saplı), 500 kg buğday sapı, 30 kg buğday kepeği, 19 kg amonyum nitrat, 11 kg üre ve 55 kg alçı.

Effects of Different Composition and Nitrogen Rates Added to Horse Manure on Mushroom Yield and Earliness in The Preparation of Horse Manure Compost

Öz

This work was carried out in attempt to find out the preparation formulas of horse manure compost under condition familiar to Turkey. The experiments were conducted at the mushroom research facilities of the Yalova Atatürk Central Horticultural Research Institute between 1985 and 1990. The wheat straw was added to the fresh horse manure bedded with wheat straw at two different rates 25% and 50%. Different rate of nitrogen such as 1.50%, 1.75%, 2%, 2.25% and 2.5% were added to the starting raw materials. Ammonium nitrate and urea were used as nitrogen sources. The nitrogen values of each form in the combinations were equalized according to pure nitrogen values. According to results obtained from trials, the nitrogen value must not be dropped under 1.75% in the starting raw materials. The biggest yield was obtained with nitrogen value of 1.75% and 2%. We couldn’t get better results when the nitrogen value of the starting raw materials was increased to 2.25% and 2.5%. The effects of treatments on earliness during 10, 20 and 30 days of a 40-day harvesting period were not found to be significant at 5% level in the Experiment-1, 2 and 3. The effect of treatments on earliness during 20 days of 40-day harvesting period in the Experiment-3 was found to be significant at 5% level. The highest yield in 20-day harvesting period was obtained from the treatment-1. The formula which has given the best results is as follows. •1000 kg fresh horse manure, •500 kg wheat straw, •30 kg wheat bran, •19 kg Ammonium nitrate, •11 kg Urea, •55 kg Gypsum,
