Bu araştırma katı solucan ve tavuk gübrelerinin kıvırcık salatada verim, bazı kalite özellikleri ve bitki besin elementi içeriklerine etkilerini belirlemek amacıyla yürütülmüştür. Cam sera koşullarında yapılan araştırmada parsel büyüklüğü 1.2 m 2 olup, her parselde 10 bitkiye yer verilmiş ve bitkisel materyal olarak Caipira kıvırcık marul (Lactuca sativa L. var crispa) çeşidi kullanılmıştır. Denemede katı solucan gübresi (SG:80 kg da-1), katı tavuk gübresi (TG:250 kg da-1), kimyasal gübreler (KG:12.5 N-4 P2O5-11 K2O kg da-1), SG (80 kg da-1) + KG (12.5 N-4 P2O5-11 K2O kg da-1), TG (250 kg da-1) + KG (12.5 N-4 P2O5-11 K2O kg da-1) ve Kontrol (K) uygulamaları yer almıştır. Hasat edilen bitkilerde kök boğazı çapı (mm), baş boyu (cm), yaprak sayısı (adet bitki-1), yaprak rengi (L, Hue ve Chroma), klorofil miktarı, toplam ve pazarlanabilir verim (kg da-1), ortalama baş ağırlığı (g bitki-1) ve makro bitki besin elementi içerikleri incelenmiştir. Araştırmadan elde edilen sonuçlara göre en yüksek toplam ve pazarlanabilir verim ile ortalama baş ağırlıkları TG + KG uygulamasından elde edilmiştir. En yüksek kök boğazı çapı SG + KG uygulamasında belirlenirken, en yüksek baş uzunluğu TG'de tespit edilmiştir. Klorofil miktarı bakımından uygulamalar arasında farklılıklar oluşmazken, renk açısından en yüksek L değeri SG, Hue değeri, KG uygulamasında ve en yüksek Chroma değeri de SG ve K uygulamalarında saptanmıştır. Analiz edilen makro elementler açısından en yüksek azot TG + KG, SG + KG ve KG uygulamalarında, en yüksek fosfor Kontrol uygulamasında, en yüksek potasyum, kalsiyum ve magnezyum değerleri ise TG uygulamalarında tespit edilmiştir.
Agricultural wastes have increased with the intensive production in recent years. These wastes that affect the physical, chemical and biological properties of soils should be composted and added to soil. In this study, composts were consisted of different agricultural wastes such as greenhouse wastes-GPW, used cocopeat wastes-UCW, spent mushroom composts-SMC and at different ratios. Used cocopeat wastes were especially chosen in this experiment because it was not preferred in compost mixtures up to the present. Five different compost mixtures were added to the soil and their effects on growth and nutrient contents of lettuce plants were determined. The experiment was carried out during two successive seasons (autumn and spring). The results showed that plant growth and yield were found higher in the compost applications than in control. Generally the highest values were obtained from M1 application (80% GPW + 10% UCW + 10% SMC) for many parameters.
The effect of different nitrogen (N) treatments on the nutrient contents of tomato (Lycopersicon esculentum Mill., cv. ‘Tayfun F1’) under different boron (B) concentrations were investigated in greenhouse conditions with four replications. Four different levels of B (0, 5, 10 and 20 mg kg–1) and three levels of N (100, 200, 300 mg kg–1) were used in this research. The results showed that tomato plant growth was negatively affected with increasing B concentrations and symptoms of boron toxicity were observed. The tomato leaf nutrient concentrations were increased in all plants with B and N treatments and 20 mg kg–1 B and 300 mg kg–1 N treatments were determined to be more effective compared to the others. 20 mg kg–1 B and 100 mg kg–1 N treatment caused the highest micro element concentrations of tomato leaf. This could be interpreted as N application having a dilution effect to be able to maintain development under conditions of toxicity of B. The plants growth under boron toxicity conditions showed increased vegetation with increasing N applications which was attributed to the dilution effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
