Cultivars under Terminal Drought Stress Effect of Vermicompost, Nitrogen and Phosphorus Fertilizers on Yield and Yield Components of Chickpea (Cicer arietinum L.) Cultivars under Terminal Drought Stress 67 83 8750 FA Sajad Kahrizy Ali Sepehri Journal Article 2018 05 01         In order to evaluate the effect of vermicompost, nitrogen and phosphorus fertilizers on yield and yield components of four chickpea cultivars under terminal drought stress, a field experiment was conducted at the Agricultural Research Station of Faculty of Agriculture, Bu-Ali Sina, university during 2014 growth season. Experiment was designed as split factorial based on randomized complete block design with three replications. Irrigation treatment  inclued two levels, without drought stress (full irrigation) and drought stress at podding stage (terminal drought) in main plots and fertilizer treatments including four levels (100 percent of vermicompost, 100 percent of chemical fertilizer, 50 percent of chemical fertilizer + 50 Percent of vermicompost and Without fertilizer) and four chickpea  cultivars (Bivanig, Arman, Azad, Hashem) were used  in sub-plots. The result showed that interaction between irrigation and cultivar was significantly in the number of pods per plant, economic yield, biological yield and harvest index. Also all studied traits were significantly affected by interaction between irrigation and fertilizer. Drought stress at podding stage decreased grain yield of Hashem, Arman, Azad and Bivanig cultivars about 41, 43, 37 and 33.7 percent, respectively. At the podding stage steress, application of 50 percent  of chemical fertilizer + 50 percent of vermicompost increased number of pods per plant, 1000 grain weight, seed yield, biological yield and harvest index about  20, 19, 47.6, 23.8 and 16 psercent respectively under stress condition. It’s notable that application of 100 percent of vermicompost improved above-mentioned traits by about by 29.7, 14.5, 39, 20 and 4.8 percent respectively. According to results, in all cultivars especially Hashem using 50 percent of chemical fertilizer + 50 percent of vermicompost for enhancing chickpea under full irrigation and drought stress at podding stage is recommended.             In order to evaluate the effect of vermicompost, nitrogen and phosphorus fertilizers on yield and yield components of four chickpea cultivars under terminal drought stress, a field experiment was conducted at the Agricultural Research Station of Faculty of Agriculture, Bu-Ali Sina, university during 2014 growth season.
