The effect of different sources of nitrogen fertilizer on yield and yield components of linseed (linum usitatissimum L.)
The experiment was performed to investigate the effect of different sources of nitrogen fertilizer on yield and yield components of linseed Norman variety.
The experiment was conducted in the form of a randomized complete block design with 13 treatments in 3 replications in April 2012 in farm of Yasouj university. Experimental treatments during : T1-control (without fertilizer application), T2- application of 90 kg.ha-1 urea, T3- application of 10 tons.ha-1 of vermicompost, T4- application of 5 tons.ha-1 of vermicompost, T5- application of Barvar1 biofertilizer (containing sAzotobacter (100 g.ha-1) T6- application of biofertilizer nanoparticles of zinc, copper, iron and nitrogen-fixing bacteria (1 kg.ha-1), T7- application of 45 kg.ha-1 urea + 5 tons.ha-1 of vermicompost, T8- application of 45 kg.ha-1 of urea + Barvar1 biofertilizer, T9- application of 45 kg.ha-1 of urea + nano biofertilizer, T10- application of 5 tons.ha-1 of vermicompost + nano biofertilizer, T11- application of 5 tons.ha-1 of vermicompost + Barvar1 biofertilizer, T12- application of 45 kg.ha-1 of urea + 5 tons.ha-1 of vermicompost + biofertilizer Barvar1, T13- application of 45 kg.ha-1 of urea + 5 Tons.ha-1 of vermicompost + nano biofertilizer.
The results showed that different fertilizer treatments caused a significant increase in morphological traits, yield and yield components, biological yield, oil yield and protein percentage of linseed compared to the control.
