| Abstract | ||
| This study was conducted to investigate the physiological effect of biofertilization EM1, phosphate fertilization on growth parameters of two Soybean varieties [Glycine max (L.) Merrill] , The study was included field experiments of two concentration of biofertilization EM1 (zero , 1.5ml/liter), four levels of phosphate fertilization (0, 40, 80, 120 kg p2o5/ ha) and two soybean varieties (Lee-74 , Senaia-2) conducted in two locations for the summer season 2011. The first in reasreches station Department of Field Crops College of Agriculture and Forestry-Mosul University in Mosul City, while the second was in Tuzkhurmatu city about 105 km North East Tikrit City. The Randomized Complete Block Design (R. C. B. D.) with three replications was used in this experiment. The results indecated that biofertilizer EM1 with concentration (1.5 ml/Liter) caused significant increase in traits: leaf area, No. of leaves /plant, Leaves and plant dry weight, Leaf Area Duration, Biomass Duration, Relative Growth Rate and Crop Growth Rate in both locations and Net Assimilation Rate in Mosul location . Phosphate fertilization level (80 kg p2o5/ ha) in Mosul location and (40 kg p2o5/ ha) in Tuzkhurmatu location was significantly Superior in growth traits: leaf area, No.of leaves/plant, Leaves and plant dry weight, Biomass Duration, Relative Growth Rate and Crop Growth Rate, while (80 kg p2o5/ ha) was gave highest rate in trait Leaf Area Duration in both locations. Senaia-2 variety Significantly Superior as compared with Lee-74 variety in plant dry weight, Biomass Duration and Crop Growth Rate in both locations, No. of leaves/plant, Leaves dry weight in Tuzkhurmatu location . Interaction between (1.5 ml/Liter EM1 × 80 kg p2o5/ ha) in Mosul location and (1.5 ml/Liter EM1 × 40 kg p2o5/ ha) in Tuzkhurmatu location gave highest rate in Leaves and plant dry weight, Biomass Duration and Crop Growth Rate in both locations, leaf area, No. of leaves/plant, Leaf Area Duration in Tuzkhurmatu location . | ||
