Effects of Different Soil Conditioners on Water Use Efficiency and Tomato Plant Growth in Loam and Clay Loam Soils

Abstract

Experiment was consisted of two different soil textures (clay loam and loam), four treatments (8% olive pomace compost, 4% perlite, 0.12% hydrophilic polymers and control) with three replications. Tomato (Lycopersicon lycopersicum L.) seedlings were transferred to each pot and plants were grown under controlled atmosphere conditions. Effects of different soil conditioners on plant water use efficiency and tomato plant growth were determined. As a result, olive pomace compost applications to loam soil saved irrigation water 45.12%, 42.99% and 38.88% compared to control, perlite and hydrophilic polymers treatments respectively. On the other hand, hydrophilic polymers treatments saved irrigation water 17.82%, 46.76% and 27.29% compared to control, perlite and olive pomace compost treatments respectively for clay loam soil. Soil pH decreased and electrical conductivity (EC) increased for both soils after the experiment. The highest soil EC value was detected with the application of olive pomace compost. Perlite application increased plant fresh weight and length while olive pomace compost increased branch numbers of tomato for clay loam soil. Root length and surface areas were maximum under olive pomace compost applications for both soils.

“…Bitki yetiştirme ortamı olarak değerlendirilmesi amacı ile pirina kompostu kullanımının, perlit ve hidrofilik polimerler ile karşılaştırıldığı çalışmada, kompost uygulamasının tın ve killi tınlı topraklar üzerine daha fazla olumlu etki yaptığı belirtilmiştir. İşler ve Kavdır (2021), tın toprağa karıştırılan pirina kompostunun, domates bitkisine uygulanan sulama suyu miktarında perlite göre %43 ve su tutucu polimere göre ise %39 oranında tasarruf sağladığını bildirmişlerdir. Killi tınlı bünyedeki toprakta ise su tutan polimerler, perlit ve pirina kompostu uygulamasına kıyasla sırasıyla %47 ve %27 su tasarrufu sağlamıştır.…”
