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 , A factorial experiment with randomized complete block design (RCBD) with three replicates , phosphate fertilizer was applied from Tri calcium phosphate source on four levels (0,40,80 and 120 Kg P.ha-1 ) ,three levels (0 , 6 and 12 ton .ha-1 ) of organic matter (composted ground corn cobs ) and two levels of biofertilizer , Mycorrhizae source (G. mossea ) (without ,with), 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 shoot system (stems and leaves for tomato plants) in the three growth periods (flowering ,early yield and last cutting ) .The level 80 kg P.h-1 and 6 ton.ha-1 with mycorrhizae inoculation was the best on shoot dry matter ,It was achieved (35.87 and 86.88) g.plant-1dry weight , but the level 80 kg P.ha-1 and 12 ton.ha-1 with mycorrhizae inoculation in the second periods was the best and achieved 92.13 g.plant-1dry weight . Results showed that concentrations of nitrogen, phosphorus were the highest on the level 80kg P.ha-1 and 6 ton.ha-1 with mycorrhizae inoculation the high percentage for nitrogen concentration were 67.74% ,83.33% and 87.85 % for the three periods compared to that of control , and phosphorus concentrations were 91.67% , 260.00 and 200.00% to all periods compared to that of control ,and potassium concentration were (2.52 , 2.31 and 1.94)%to all growth periods compared to that of control .The results showed the highest dry weight of fruit was in the treatment 80kg P.ha-1 and 12 ton.ha-1 with mycorrhizae inoculation which was 10.58 g.friut-1 dry weight , while the treatment 80kg P.ha-1 and 6ton.ha-1 with mycorrhizae inoculation was the best in percentage of percent total acidity of fruit and its solid which were achieved 0.72% and 14.30 kg . cm-3 .
