Abstract

A field experiment was couducted in clay loam soil with three replicates and under RCBD design to figure out the effect of biofertilizer and yeast adding method on the availability of phosphorus, growth and yield of onion. The results showed that the adding of mycorrinzal fertilizer increased the phosphorus availability in soil , green mass and total yield (5.493 mg kg-1, 0.292%, 0.473% and 5.862 mcg h-1) comparing with the other treatments which gave (4.261 mg kg-1, 0.348%, 0.226% and 4.995 mcg h-1).
The interaction between in mycorrinzal fertilizers and yeast the excellence of the yeast treatment (soil Treatment) on the phosphorus concentration in soil /green mass and total yield (5.118 mg kg-1, 0.488% , 0.308% and 5.836 mcg h-1) comparing with the foliar upplication of yeast (4.840 mg kg-1, 0.436% , 0-.272% and 5.439 mcgh-1).
