  This experiment carried out during 2010-11 and 2011-12 cropping years to study the effect of variant levels of fertilizers containing nitrogen, normal irrigation and irrigation hindering on some agronomical characteristics of isabgol, in Smaeel-Abad Agriculture Research Center of Qazvin. The research was carried out by using two split plot experiments based on randomized complete block designs with three replications. The experiments were repeated for two consecutive years and finally the research results were performed by combined analysis. Main plots were normal irrigation (I1) and cutting off irrigation during seed filling stage (I2), sub plots were nitrogen containing fertilizers: vermicompost, cattle manure and chemical nitrogen fertilizer (urea 46%) with three levels, containing 30, 60 and 90 kg.ha-1 of pure nitrogen. Effects of irrigation and nitrogen containing fertilizers on mucilage yield (P≤0.01) and mucilage percentage (P≤0.05) were significant. Interactions of irrigation × nitrogen containing fertilizers on biological yield and relative water content (P≤0.05), seed yield and 1000 seed weight (P≤0.01) were also significant. According to results of this research; the highest application level of vermicompost in normal irrigation condition, showed better results for production of isabgol plant in the research area.

  This study was conducted as split plot factorial experiment was done based on a randomized complete block design with 18 treatments and three replications, on research field of the Gonbad Kavous University, Golestan, Iran in winter 2017. In this experiment the treatments of irrigation included; control (non-stress), irrigation cutoff at flowering stage and irrigation cutoff at seed filling stage) was the main-plot and factorial of salicylic acid (SA) (0, 0.4 and 0.8 mM), spermine (Spm) spraying (0 and 0.02 mM) was as a sub-plot. According to the results of the experiment, the highest 1000-grain weight (2.00 g) was obtained in irrigation cutoff at seed filling with 0.4 mM salicylic acid spraying and biological yield (2472.37 kg/ha) was observed under normal irrigation conditions and SA0.8mM+Spm0.02mM spraying. In addition, the most of Seed swelling factor (12.42 ml) and seed mucilage percentage (21.33%) were obtained in under moderate and severe stress conditions, respectively. Also, the highest grain yield (574.05 kg ha-1), seed mucilage yield (102.12 kg ha-1) and seed husk percentage (72%) were observed to foliar spraying 0.8 mM salicylic acid and 0.02 mM spermine in irrigation cutoff at seed filling. According to the results, the spraying of salicylic acid and spermine in irrigated conditions at flowering and seed filling stages prevented significant traits from being studied and the highest grain yield, biological yield, harvest index, seed husk percent, seed mucilage percentage, seed mucilage yield were caused.
