20.500.12556/RUL-148239 Effect of different walnut and hazelnut leaf compost treatments on yield and phenolic composition of Lactuca sativa L. The use of compost made from the leaves of Juglans regia has long been controversial because of its inhibitory effect due to the presence of juglone. Therefore, the aim of our study was to replicate the typical habits of farmers and gardeners, where the dried leaves are collected at the end of the season and placed in a composter. Then, the effects of the different treatments on the yield of the plant (lettuce), secondary metabolism, and possible toxicity of the compost of the grown plant were evaluated. The lowest yield of lettuce was obtained in soil with composted walnut and hazelnut leaves, while the highest yield was recorded in soil with compost control, soil with composted walnut leaves and grass with the addition of composting agent and soil with composted walnut leaves with addition of composting agent. Some allelochemicals were still present in the compost but at such low levels that they did not affect yield. We suggest that dry walnut leaves and cut grass can be used for composting, while dry hazelnut leaves still contain some allelochemicals after two years that significantly inhibit plant growth and thus yield, so we would not recommend their use for composting. allelopathy lettuce naphthoquinones toxic residues HPLC mass spectrometry LC-MS oreh leska odpadno listje kompost solata fenolne spojine toksične snovi zaviranje rasti true false true Angleški jezik Slovenski jezik Članek v reviji 2023-08-04 10:39:08 2023-08-04 10:39:16 2024-12-06 12:35:57 0000-00-00 00:00:00 2023 0 0 10 str. iss. 14, art. 2738 Vol. 12 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 635 2304-8158 10.3390/foods12142738 160627203 foods-12-02738.pdf foods-12-02738.pdf 1 FFC73FA49066CF793EA484834D5149FF 1978f86725782da986dee9a48497a20c51327fde5b33aa88f8cfb1f196e4f997 b708c03b-32a2-11ee-aeaf-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=172292 https://www.mdpi.com/2304-8158/12/14/2738 1 671e1e02-32a2-11ee-aeaf-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=172291 Biotehniška fakulteta 0 0 0
