This study was conducted at the Indian Institute of Technology, Delhi, India, in 2002 to evaluate the potential of AMF in combination with different concentration levels i.e. 0, 25, 50, 75 and 100% of recommended dose of P in reducing the amount of P required for proper growth of Morus alba var. Sujan Puri in alkaline soils. Each treatment was replicated five times. The following combinations were made: T1 - control; T2 - mycorrhiza only; T3 - mycorrhiza + 25% P; T4 - mycorrhiza + 50% P; T5 - mycorrhiza + 75% P, T6 - mycorrhiza + 100% P; and T7 - 100% P only. The trend observed in percent infection in roots was in the order of T5>T6>T4>T3>T2. Similar trend was observed with number of spores/100 g soil. Although the treatments were found to be different from each other, the difference was not significant except in case of available P content. The C, N, P and K contents of all the treatments were increased as compared to control plants. The effect of AMF inoculation and different doses of P showed that the total biomass yield was higher in all mycorrhizas inoculated plants as compared to uninoculated control. The increase in all plant growth parameters and total biomass yield was significantly superior over the control. |
