| Abstract | ||
| A pot experiment was conducted in the green house in college of agric.-univ. of tikrit during 2010- 2011 season to evaluate effectiveness of phosphate rock (PR) through direct application or mixing with organic materials and its effect on growth and yield of wheat in a gypsiferous soil. this study consisted four P source which it are TSP, PR, PR+1% Peat, and PR+1% Manure, P level (as PR) which eousisted of four levels i.e: 0, 30, 60, and 90 (mg P.kg soil -1) in three replicates using RCBD, design. The study was conducted in a green house by packing 6 kgs of soil in pots. Nitrogen and potassium fertilizers were added by the some level 0f each to all the pots. The soil was mixed with chemical and organic fertilizers and put in pots. The soil was cropped to wheat (Triticum aestivum L.) var. Tamouz. After harvest straw yield , grain yield, and P uptake in strow and grain, and bicarbonate extractable P were measured and determined. Result shown that.the best source and level of P was PR+1% Manure at 90 (mg P.kg soil -1) which was superior over the other sources with a significant sources in all growth, , yield and soil properties studied. The differences were significant between P sources in straw and grains weight. P sources differed significantly after harvest in Olsen P in soil after harvest. The sources PR+1% Manure at 90 (mg P.kg soil -1) was the best significantly. and uptake in straw and uptake in grain. On other parameters (strow weight, grain weight, total P uptake) there were no significant difference between the level 90 and 60 achieved the highest value. | ||
