| Abstract | ||
| A field experiment was conducted on vegetable field - Horticulture department – College of Agriculture -Abu Graib , Tomato (Hybrid Jenan) cultivated in spring season of 2012 , phosphate fertilizer was added from TSP 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 from biofertilizer ,Mycorrhizae source (G. mossea ) (without or with), All fertilizers was added in soil mixture , A factorial experiment with randomize completely blocks design with three replicates and twenty four treatments .The experimental results showed A high significant with a high levels from phosphate and organic fertilization with inoculation on fruit quality ( percentage of total soluble solids and Ascorbic acid or vitamin C) and phosphate concentration on tomato leaves during three growth periods ,The best level was 80 Kg P.h-1 and 6 Ton .h-1 with mycorrhizae inoculation which gave increase on fruit quality was (34.64 and 33.76 ) % to above fruit quality respectively . The same level gave increase in phosphorus concentration for three growth periods up to 19.05% , 15.79% and 13.64% respectively compared with control . | ||
