Effect of organic manures on nutritional quality of chicory under water deficit

Abstract

Drought stress and organic manure have vigorous role in plant growth. In order to alleviate effects of drought on chicory (Chicorium intybus L.), poultry and livestock manures were used at different levels of drought which induced according to evaporate level from evaporation pan. Aim of this research was to improve the chicory nutritional and pharmaceutical suitability under drought. Results suggested significant effects of both manures on chicory mineral accumulation and phytochemicals. The highest concentration of potassium (K), phosphorus (P) and manganese (Mn) were obtained with poultry application at moderate drought, but no significant difference with livestock manure on potassium in severe drought. Livestock manure usage increased zinc (Zn) concentration in severe drought significantly. Both manures increased total phenolic compounds in severe drought significantly, but total carbohydrate significantly affected by poultry manure. Therefore, chicory inulin and chicoric acid under drought conditions were significantly affected by both poultry and livestock manures.

Keywords: Livestock manure, poultry manure, mineral accumulation, phytochemical, drought stress, Chicorium intybus.
