Abstract

Field experiments were carried out during the two successive seasons 2014 and 2015 at the farm of Sakha Horticulture Research Station, Kafrelsheikh Governorate, Egypt to study the efficiency of some approaches (silica nanoparticles, bio-insecticides (Dipel 2X), clove oil, peppermint oil and insecticide) on green onion growth, yield, mineral nutrients and controlling the land snails. Experimental treatments randomly arranged in randomized complete blocks design with three replicates. Obtained results showed that all treatment significantly promoted the growth and yield such as plant weight (g), plant height (cm), leaf area (cm²), number of leaves, fresh and dry weight of leaves (g), total yield (ton fed.^-1), total soluble solids and protein (%) of green onion plants. Leaf photosynthetic pigment was increased especially in plants treated with chemical insecticide and silica nanoparticles in both seasons, which recorded 67.00, 65.90 and 64.17, 63.57 as compared control 54.57, 56.67, respectively. In addition, silica nanoparticles treatment increased leaf NPK % followed by clove and peppermint oil compared with control (tap water). On the other hand, silica nanoparticles was the highest efficiency treatment in controlling land snails in both seasons, the mean general reduction percent gave 90.73% followed by insecticide treatment which the mean general reduction percent gave 87.46%, respectively. Generally, it could be concluded that, silica nanoparticles is capable of using as a new approach to enhance growth and control land snails on of green onion plant.

Key words: Bio-insecticides (Dipel 2X), Clove oil, Green onion, Peppermint oil, Silica nanoparticles, Snails.
