Comparative Effect of Organic Fertilizers on Growth and Chemical Constituents of Plantago Ovata Plant
Journal Title: Caspian Journal of Applied Sciences Research - Year 2012, Vol 1, Issue 6
Abstract
This study was conducted in Experimental Farm of National Research Centre , during two successive seasons to evaluate the influence of different kinds and levels of organic fertilization (compost, compost tea and humic acid) on the growth, production and chemical constituents of Plantago Ovata plant. Generally, all fertilizer treatments had a pronounce increment for growth parameters of Plantago ovata. The maximum mean values of fixed oil content (%), was recorded as a result of foliar application with humic acid at level of 0.06 %. The superior stimulation for mucilage accumulation was observed with the highest level of compost tea applied followed with the highest humic acid level. The uptake of the nutrients N, P, K, Fe, Zn and Mn, in general, increased significantly as a result of supplying various sources of organic fertilizers. The highest mean value of total carbohydrate content (%) was observed with the highest humic acid level. The highest level of humic acid and compost tea caused the maximum values of soluble and non-soluble sugars.
