متن يادداشت

In order to study the effects of green manures and mineral fertilizers on wheat growth and soil properties an experiment was conducted as split plot in base of randomized complete block design in 3 replications in 2006 and 2007 on Hamoon wheat cultivar. Main plots include N, P and K fertilizers, include 0, 50 and 100 percent respectively and subplots were different sources of green manures include, 1-check 2-Clover 3-Bean and 4-Barley. In the first year green manures were planted in each plot and the third cutting of plants in each plot were added to the soil of the plot. Green manure of Bean increased to soil after pod appearance. Before sowing of wheat and application of N, P and K, soil properties were determined at depth of 0-30 cm. In the second year, wheat was planted in plots and N , P and K applied in soil. Amount of dry matter that added to soil by green manure application of barley, Clover and bean were 4824, 1550 and 3532 (kg ha-1), respectively. Barley green manure significantly increased soil organic carbon %, available phosphorus and available zinc. Green manure had no significant effects on density and amount of plant root. N, P and K fertilizers increased wheat root and grain yield. Green manure had no effect on grain yield due had not effect on bulk density and root growth.
