Bazı Kontrollü Salınımlı Gübrelerin ve Uygulama Metotlarının İtalyan Çimi (Lolium multiflorum)’nin Gelişimi Üzerine Etkisi

Toprağa uygulanan gübrelerin yarayışlı hale geçerek bitkiler tarafından alınması besin elementine bağlı olarak birçok faktör tarafından etkilenmektedir. Gübrelerin etkinlik derecesini arttırmak için kontrollü salınımlı gübreler (KSG) yeni bir teknoloji olarak geliştirilmiştir. Yapılan bu çalışmada N, P ve K içerikleri yönünden benzer özellik gösteren 5 farklı KSG’nin (115, 414, 715, 815 ve 2415) ve farklı uygulama (serbest veya paketli) metotlarının İtalyan çiminin gelişimi üzerine etkisi kontrollü şartlarda belirlenmiştir. Torf ile doldurulmuş saksı içerisinde yetiştirilen bitkilere KSG’ler paket halinde ya da serbest halde uygulanmıştır. Tohum ekiminden itibaren 4 aylık periyod içinde gübrelerde zamanla meydana gelen toplam ağırlık kayıpları, besin elementi içeriğindeki meydana gelen kayıplar, birim gübre karşılığında toplam üretilen yaş ve kuru biomas ve saksı başına hasatla kaldırılan toplam besin elementi miktarları belirlenerek gübreler ve uygulama şekilleri karşılaştırılmıştır. Sonuç olarak, 414 (% 29.90) ve 815 (% 15.03) nolu gübrelerde ağırlık kaybı en az olurken biomas üretimi en fazla olmuştur. Her iki gübrenin etkinliği diğerlerine oranla istatistiksel olarak önemli düzeyde daha yüksek olduğu tespit edilmiştir. Birim gübre karşılığında üretilen biomas miktarına göre ise 815 açık farkla öne çıkmıştır. Uygulama şekli açısından “serbest” uygulamanın daha etkili olduğu tespit edilmiştir. Özellikle saksıda yetiştirilen ve uzun hayat döngüsüne sahip bitkilerde 815 nolu gübrenin serbest uygulama şekli önerilmiştir.

Effect of Some Controlled Release Fertilizers and Application Methods on the Growth of Italian Ryegrass (Lolium multiflorum)

The fertilizer applied to the soil is affected by many factors depending on the nutrient element until it will be dissolved and taken up by plants. Controlled release fertilizers (CRF) have been developed as a new technology to increase the efficiency of fertilizers. In this study, effect of 5 different CRFs (115, 414, 715, 815, and 2415), which have similar characteristics in terms of N, P and K contents, and different application methods (incorporated or in the package) were determined on the development of the Italian ryegrass under controlled conditions. CRFs were incorporated or applied in the package to the ryegrass grown in pots filled with peat. In 4-month period starting from seed sowing, fertilizers and application methods were compared by determining the total weight loss occurred in fertilizers over time, total loss in fertilizer nutrient content, total fresh and dry biomass produced per unit fertilizer, and the total amount of nutrients removed by biomass per pot. As a result, while the weight loss was the least in 414 (29.90%) and 815 (15.03%), their biomasses were the highest. It was determined that the effectiveness of both fertilizers is higher than the others. According to total biomass produced per unit fertilizer, 815 came to the fore with an open gap. Incorporating was more effective in terms of application method. 815 and incorporating method were recommended for plant in container-grown and having with a long-life cycle.
