Effects of organic and inorganic fertilizers on yield and yield components of Plantago ovata Forsk.
Abstract
To study the response of Plantago ovata Forsk to organic and inorganic fertilizers a green house experiment was conducted in a completely randomized design with three replications. Organic fertilizers were cow manure (4 and 8 tons/ha) and municipal waste compost (4 and 8 tons/ha) and inorganic fertilizers were N30P10, N30P20 , N60P10 and N60P20 kg/ha respectively. The results indicated that yield and yield components of Plantago ovata in organic fertilizers were higher than inorganic fertilizers. Plant height, spike length, grains weight per spike, grains weight per plant, straw weight per plant and grain and straw yields per box were highest in 8 tons/ha municipal waste compost. However percentage of mucilage was highest in plants fertilizerd with cow manure .
