| Abstract | ||
| A field experiment was conducted on the vegetable field - Horticulture department – College of Agriculture -Abu Graib , Tomato cultivated (Hybrid Jenan) in spring season of 2012 , with three replicates ,phosphate fertilizer was added from Tri super phosphate source on four levels (0,40,80 and 120 Kg P.ha-1 ) ,three levels (0 , 6 and 12 ton .ha-1 ) from organic matter (ground corn cobs composting )and two levels of biofertilizer ,Mycorrhizae source (G. mossea ) (without ,with), A factorial experiment with randomized complete block design ,All fertilizers was added in soil mixture. Results showed A high significant increase with the increase in phosphate and organic fertilization and inoculation on dry matter for root system in the three growth periods (flowering ,early yield and last cutting season) with percentage 269.17%, 156.16% and 196.55 % but the best level on nitrogen concentration in the roots was 80kg P.ha-1 and12 ton.ha-1 with mycorrhizae inoculation and high values achieved (2.28,1.69and 1.14)% to growth periods respectively and in the fruit 2.17%, for the same level of phosphor concentration in the roots with high values achieved (0.15 ,0.08 and 0.11 ) % for growth periods, respectively . While for fruit it was 0.48% . Potassium concentration in the root system on the first period the best level 40kg P.ha-1 and 6 ton.ha-1 with mycorrhizae inoculation and high values achieved 2.32%,while the second and third periods a high values achieved 1.67 % and 1.93 % to two periods respectively ,while in the fruit the value was 5.45%. | ||
