The effect of chemical and biological fertilizers on leaf characteristics, yield and nutrient uptake and consumption efficiency, phosphorus and sulfur in Camelina sativa L.

The aim of this study was to investigate the effect of chemical fertilizers of nitrogen, phosphorus, sulfur and biofertilizer on some growth indicators of Camelina sativa L. experimental plant during the crop year 2016 in a farm located in Kazerun and as a factorial in the form of complete randomized block design with three replications. Treatments include fertile biofertilizer 2 containing phosphate solvent bacteria (Pseudomonas putida Strain 13P bacteria and agglomerans Pantoea Strain 5P) as the first factor in 2 levels (consumption and non-consumption) and the second factor including chemical fertilizers including control treatments, nitrogen, phosphorus, sulfur fertilizers (50 respectively). (200 and 100 kg / ha) alone were optimal and chemical fertilizer treatment was 30% less than optimal. The results showed that the application of biofertilizer was significant only on crop yield and phosphorus, sulfur and nitrogen uptake traits. Chemical fertilizer treatment was significant on all traits, and the interaction of biofertilizer treatment with chemical fertilizer on grain yield, crop yield and phosphorus, sulfur and nitrogen adsorption traits was significant. The combined use of biofertilizers with nitrogen + phosphorus + sulfur chemical fertilizer compared to control increases grain yield by 86.85%, improves crop yield of phosphorus, sulfur and nitrogen by 19.48, 12.62 and 14.90 kg / kg, respectively, and its adsorption efficiency. The elements were 42.2%, 30.01 and 36.97%, respectively. The combined use of chemical fertilizers with biofertilizer compared to control increased the leaf area index by 13.60%, increased the plant weight ratio by 23.78% and the leaf surface area. Nitrogen + phosphorus treatment compared to control showed an increase in plant growth rate of 53.64%. The best fertilizer combination in this experiment to increase the yield of whole plants was the combination of chemical fertilizer treatments containing nitrogen, phosphorus and sulfur with biofertilizers.
