Abstract
In order to determine the fertility status of soil and nutritional status of hazelnut grown in the district of Ordu, 65 orchards in which Tombul and Palaz hazelnut species grown were sampled for soil and leaf. Some soil chemical and physical properties and plant nutrient levels of soil and leaf samples were determined. The data from plant and soil analysis were compared with the adequate ranges and then sufficiency levels were determined. According to the soil analysis, the soils of hazelnut orchards were commonly acid, low in lime, clay and clay loam in texture and, have sufficient nitrogen and organic matter. The soils were deficient especially B and P, K, Ca, Mg and Zn. The deficiency ranges for these nutrients as the percentage of soils sampled were 93.9%, 49.2%, 69.2%, 38.5%, 12.3% and 75.4% respectively for B, P, K, Ca, Mg and Zn. Iron, Cu and Mn contents of soil were in sufficiency ranges.ln the leaf samples taken from the hazelnut orchards, Ca, Fe, Cu and Mn contents were sufficient and excess levels while nitrogen in 57.0%, P in 64.6%, K in 66.2%, Mg in 58.5%, Zn in 26.9% and B in 91.5% were deficient levels.
Özet
Bu araşt ı rmada Ordu yöresinde f ı nd ı k yetiştiriciliğ i yap ı lan topraklar ı n verimlilik ve bitkinin beslenme durumunu belirlemek amac ı yla 65 adet toprak, Tombul ve Palaz çe şit fı nd ı k bitkisine ait 65'er adet yaprak örnekleri al ı narak analizleri yap ı lm ışt ı r. Topraklar ı n baz ı fiziksel ve kimyasal özellikleri ile bitkilerin besin maddesi içerikleri belirlenmiş ve elde edilen veriler s ı n ı r değerleri ile karşı laşt ı rı larak yeterlilik düzeyleri ortaya konmaya çal ışı lm ışt ı r. Araşt ı rmadan elde edilen sonuçlara göre, yöre topraklar ı n ı n asit reaksiyonlu, az kireçli, killi ve killi t ı nl ı bünyeye sahip, azot ve organik madde bak ı mı ndan yeterli oldu ğ u saptanmışt ı r. Yöre topraklar ı n ı n yaklaşı k %49.2'sinin P, %69.2'sinin K, %38.5'inin Ca, %12.3'ünün Mg bak ı mı ndan orta ve düşük; %75.4'ünün Zn, %93.9'unun B bak ı mı ndan noksan ve düşük olduğ u belirlenmiştir. Toprakları n Fe, Cu ve Mn içeriklerinin yeterli seviyelerde de ğişim gösterdiğ i tespit edilmiştir. Fı nd ı k bahçelerinden al ı nan yaprak örneklerinin yakla şı k %57.0'sinde N, %64.6's ı nda P, %66.2'sinde K, %58.5'inde Mg, %26.9'unda Zn ve %91.5'inde B içerikleri noksan iken; Ca, Fe, Cu ve Mn içeriklerinin yeterli ve fazla miktarlarda oldu ğ u saptanmıştı r.
