Abstract:   (21824 Views)
An experiment was conducted to study the effect of different methods of magnesium sulfate application and cultivar on yield and yield components of lentil (Lens culinaris Med.) under Khorramabad climatic condition. This experiment was a factorial based on a randomized complete block design with three replications performed at the Agricultural Collage of Lorestan University in 2008. Different methods of magnesium sulfate application as the first factor (control treatment, soil application, foliar application, seed inoculation with fertilizer, foliar+ soil application and foliar+ seed inoculation method) and cultivar as the second factor (Gachsaran variety and Filip-92-12L variety) were applied. Analysis of variance showed that the interactions among different methods of fertilizer application and variety on plant characteristics were significant. Also, analysis of variance showed that plant height and 1000 seed weight (P<0.05) were significantly affected by the variety factor. The varieties did not have any significant effect on other characteristics. Also the effect of different methods of magnesium sulfate application on 1000 seed weight was non-significant. However, grain yield, the number of pods per plant, biological yield and harvest index (P<0.01), plant height (P<0.05) were significantly affected by different methods. Among the different methods of fertilizer application, soil application resulted in the highest grain and biological yield and plant height. Also, the highest 1000 seed weight, the number of pods per plant and plant height all were obtained using foliar+ soil application treatment. The highest harvest index was obtained using seed inoculation method. Grain yield showed a significant positive correlation with the number of pods per plant and biological yield (P<0.01). A significant and negative correlation was observed between grain yield and harvest index (P<0.01). Accordingly, soil application of magnesium sulfate and Filip-92-12L variety may result in the highest amount of lentil yield.
