Intercropping of Green Garlic (Allium sativum L.) Induces
Except for the shoot concentration of nitrogen (N), the macroelement contents of the cucumber plants were significantly influenced (Table 1). Intercropping with any amount of green garlic except for 150 g (T1) significantly increased the N concentration of cucumber roots and the P concentration in the shoots.
Problems arise when plants are both deprived of or are overexposed to zinc molecules, and the increased industrial mining or refuse of manmade products can disrupt natural amounts of zinc in soil and water.
The Guidebook does not discuss the mining of ores that are extracted using strip mining methods, including aluminum (bauxite), phosphate, and uranium. The Guidebook also does not discuss mining involving extraction of coal or aggregates, such as sand, gravel, and limestone.
Hydroponically grown cucumbers develop zinc deficiency when plants have too low zinc in the nutrient solution. Normal zinc levels in hydroponic solutions runs at 0.10.5 ppm. The symptoms of deficiency are not well defined, but usually a slight interveinal mottle develops on the lower leaves, this symptoms spreads up the plant.
Effect of copper on growth in cucumber plants (Cucumis
Application of copper stress. After the appearance of the third leaf, 4 g of copper chloride per gram of sand per day were added to the Hoagland solution for 5 days, leading to a final Cu supply of 20 g g1 sand (Cu treatment). The control plants were watered with nutrient solution without additional copper.
Determination of Cu, Zn and Cd in Soil, Water and Food
In spite of this in crops of the plants which were grown on this soil, content of Cu and Zn does not exceed the allowed concentration limits, Cd content was not found. Study plants were green been, mauhroom, green walnut, green pepper, cucumber, cherry, potato, tomato, walnut, garlic, dry been and corn.
The Effect of Zinc Oxide Nanoparticles on Safflower Plant
Considering the importance of nanoparticles in today's world, this research investigated the effect of Zinc oxide nanoparticles on the concentration of guaiacol peroxidase, polypeptide oxidase, dehydrogenase and malondialdehyde in four plant sample groups in greenhouse and laboratory conditions.
Xylem sap mineral analyses as a rapid method for estimation
Three cucumber plants (Cucumis sativus L., cv. Semcross) were grown in each plastic pot filled with 1 kg soil (dry weight) for 34 days. Cucumber is one of the most widespread horticultural crops and about 90% of cucumber plants are cultivated using alkaline soils with a relatively high CaCO 3 content (Bacaicoa and GarcíaMina, 2009).
