تأثیر کود بیولوژیک فسفر بارور 2 و سوپر فسفات تریپل بر عملکرد، کیفیت و جذب عناصر در یونجه یکساله گونه اسکوتالاتا (Medicago scutellata, cv. Robinson)

In order to study the effects of phosphate biofertilizer Barvar 2 and triple super phosphate fertilizer on yield, quality and nutrient uptake in Medicago scutellata, cv. Robinson, a field research work was done in the Research Field of Agricultural College, Shahed University, located in Tehran, Qom highway in 2006. The treatments included phosphate biofertilizer Barvar 2 at two levels including control and triple super phosphate fertilizer at the levels of control, 75, 150, and 225 kg/ha. The experiment was carried out as a factorial on the basis of randomized complete block design with three replications. After sampling, yield, protein, fiber, phosphorous (P), potassium (K), calcium (Ca), nitrogen (N), and sodium (Na) uptake were determined in the plant samples. The results showed that the amounts of yield, protein, fiber and nutrients including P, K, Ca, and N was the highest with the application of biofertilizer and chemical fertilizer at 75 kg/ha, The lowest level of yield, protein, fiber and nutrient uptake was related to the control treatments of biofertilizer and triple super phosphate.
