Abstract

Nematod enfeksiyonları, patlıcan gibi ürünlere ciddi zararlar vermektedir. Nematodların kırmızı patlıcan (scarlet eggplant) üzerindeki etkilerine dair bilgiler sınırlıdır. Bu çalışma, bahçe patlıcanlarında toprak ilavelerinin toprak nematodlarının popülasyon yoğunlukları üzerindeki etkisini araştırmıştır. Çalışmada tekrarlanan uygulamalarla tamamen rastgele blok deneme deseni kullanılmıştır. Denemeler, Meloidogyne, Hoplolaimus, Helicotylenchus ve Pratylenchus olmak üzere dört nematod türü ile bulaşık bir tarlada yürütülmüştür. Parsel başına nematod sayıları çıkarılmış, bitki boyu şerit metre ile ölçülmüş ve yaprak sayısı sayılmıştır. Biochar (10 ton ha-1 (%100)), bu nematodların kontrolünde en etkili olan uygulama olmuştur. Bunu %100 oranında inek gübresi ve Bauhinia purpurea, ardından %50 oranında (5 ton ha-1) inek gübresi ve %50 Bauhinia sp. takip etmiştir. Hoplolaimus sp. en çok çoğalan veya en çok hayatta kalan tür olmuş, özellikle de %50 biochar üzerinde; bunu %50 Bauhinia sp. üzerinde Pratylenchus sp. izlemiştir. Tüm uygulamalarda benzer nematod popülasyonları gözlenmiştir. Dikimden 3 hafta sonra (WAT), %50 inek gübresi, %100 Bauhinia sp. ve %50 Bauhinia sp. kontrol grubuna kıyasla daha uzun bitkiler üretmiştir. Dikimden 5 hafta sonra, en uzun bitkileri %50 inek gübresi sağlamış, bunu sırasıyla %100 Bauhinia sp., %50 Bauhinia sp., ardından %50 ve %100 biochar izlemiştir. Dikimden 3 hafta sonra, biochar hariç tüm organik kontrol ajanları kontrolden daha iyi performans göstermiştir. Dikimden 4 hafta sonra, %50 biochar hariç tüm organik kontrol ajanları kontrol grubundan daha iyi performans göstermiştir. Son olarak, dikimden 5 hafta sonra en iyi kontrol materyali %100 inek gübresi olmuş, bunu %100 Bauhinia sp., %50 Bauhinia sp., %100 biochar ve %50 inek gübresi izlemiştir. Bu toprak ilavelerinin tamamı önerilmektedir.

Explore the Nematodes Associated with Scarlet Garden Eggplant (Solanum aethiopicum) and Implement Soil Amendment for Effective Management

Abstract

Nematode infections cause severe damage to crops like eggplants. Information on the effects of nematodes on scarlet eggplant is rare. This study investigated the effect of soil amendments on soil nematodes population densities under garden eggplants. The completely randomized block design with replicated treatments was utilized. The trials were conducted in a field infested with four nematode species: Meloidogyne, Hoplolaimus, Helicotylenchus, and Pratylenchus. Number of nematodes per plot were extracted, plant height was measured with tape, and number of leaves were counted. Biochar (10 tons ha-1 (100%)) excelled in the control of these nematodes, followed by cow dung (100%) and Bauhinia purpurea (100%), then cow dung (5 tons ha-1 (50%)), and Bauhinia sp. (50%). Hoplolaimus sp. multiplied or survived most, particularly on biochar (50%) followed by Pratylenchus sp. on Bauhinia sp. (50%). All treatments had similar nematode populations. At 3 weeks after transplanting (WAT), cow dung 50%, Bauhinia sp. 100%, and Bauhinia sp. 50% induced the production of taller plants than the control. At 5 WAT, cow dung 50% was the best material for producing taller plants followed by Bauhinia sp. 100% and Bauhinia sp. 50% then biochar (50 and 100%). At 3 WAT, all organic control agents performed better than control, except for biochar. At 4 WAT, all the organic control agents except biochar 50% performed better than control. Finally, at 5 WAT best control material was cow dung 100% followed by Bauhinia sp. (100%), Bauhinia sp. (50%), biochar (100%), and cow dung (50%). These amendments are all recommended.
