Effect of Different Levels of Organic and Inorganic Fertilizers Containing Nitrogen and Irrigation Hindering on Quantitative and Qualitative Yield of Isabgol (Plantago ovata L.)

This experiment aimed to investigate the effect of variant levels of organic and inorganic fertilizers containing Nitrogen, normal irrigation and irrigationhindering on some agronomical characteristics of Isabgol (Plantago ovata L.). The research was carried out by adopting two distinct experiments in form of split plots by Randomized Complete Block Design with three replications at Smaeel Abad Agriculture Research Center of Qazvin province, Iran. The experiments were repeated in two consecutive years and finally the research results found by combined analysis. Main plots were normal irrigation and the irrigation hindering during seed filling stage. Sub plots were organic and inorganic fertilizers containing Nitrogen such as Vermicompost (VC), Farm yard manure(FYM) and chemical nitrogen fertilizer(Urea ۴۶%) that each one applied in three levels containing ۳۰, ۶۰ and ۹۰ kg/ha of pure nitrogen. Effects of irrigationand fertilizers containing Nitrogen on Mucilage yield (P≤۰.۰۱) and Mucilage percentage (P≤۰.۰۵) were significant. Interactions of irrigation × fertilizerscontaining Nitrogen on biologic yield and relative water content (P≤۰.۰۵), harvesting index, grain yield and ۱۰۰۰- kernel weight (P≤۰.۰۱) were significant. According to results of this research; the highest application level of Vermicompost in normal irrigation condition, showed better and stronger results in Isabgol production
