Mineral Contents of Weed Crops In Central Anatolian Region

Abstract

Objective of the research is to determine the mineral contents of weed crops intensively grazed by livestock of Central Anatolian Region. A total of 11 weed crops (Sinapis arvensis, Lamium album, Malva spp., Convolvulus arvensis, Chenepodium album, Alhagi spp., Sanguisorba minor Scop., Amaranthus spp., Taraxacum officinale, Polygonum cognatum and Sorghum halepense) collected from pastures and field of Kayseri were used as the material of the research. Plant samples were collected at blooming periods during June of the year 2011. Samples were dried and mineral contents were determined with 3 replications. Statistical analyses were performed based on randomized block design. Phosphorus, Calcium, Potassium, Nickel, Cadmium, Lead, Copper, Manganese, Sodium, Zinc, Iron, Magnesium and Boron were determined in the weed plants in dissimilar numbers. The close analysis indicated that the weed seeds contained Cu 8.115-9.360, Mn 65.905-77.890, Zn 30.405-42.105, Fe 254.0-290.5, Mg 2118.0-2414.0, B 6.385-9.655, Ni 0.2305-0.2945, P 2640.5-3307.5, Ca 8193.0-8965.0, K 10221.51-12332.0, Cd 0.1625-0.2235, Pb 0.3345-0.4160 and Na 1181.51-1475.5 mg kg-1, respectively. Results indicated that weed plants of Central Anatolia were rich in trace elements and there was no need for supplemental trace elements.
