Abstract

A field experiment was carried out in a greenhouse belong to plant protection office- Ministry of Agriculture in order to study effects of bio fertilizer and organic matter addition in presence of phosphate rock and the interaction in the availability of phosphorus in soil and the absorbed from it as well as its relation with growth and yield of cucumber during 2015. Experiment Add two types of the first bio-compost bacteria Bacillus and second fungi Mycorrhiza and two levels of organic matter with the addition of rock phosphate for all transactions by recommendation included, the first transaction T1 is fertilized microbiological with two levels of organic matter first level Add organic matter and the level of the other without organic matter, The second transaction T2 which added to bacteria Bacillus with the addition of organic matter or without the addition of organic material, and the third treatment T3, which added to fungi Mycorrhiza with the addition of organic matter or without organic matter and finally. It obtained the highest values of the finished items in the soil after 45 days from sowing and the percentage of increase as a percentage of treatment T4M1 that were fertilized with bacteria and fungi (19.18 and 18.83 and 16.81, 42 and 25.75%) for each of the N, P, K, Fe and Zn sequentially compared with treatment T1M1 which was without vaccination was the highest percentage increase of the elements in the papers as a percentage (N, P, K) and Fe), and Zn), which gave (11.14 and 26.06 and 3.84)% and (36.6 and 16.65)% sequentially for the treatment of T4M1 which were fertilized with fungi and bacteria, compared with the treatment T1M1 which was without vaccination after 45 days from sowing, this confirms that the bio-fertilize a clear role in those qualities. Has made use of bio-fertilization best results was the sole source of phosphorus rock phosphate is added in this study.
