Abstract

In order to test the effect of different constituents of GOLDEN BIOPHOSPHATE fertilizer (A combination of concentrated ROCK PHOSPHATE, SULFUR, THIOBACILLUS, and organic matter), an experiment was carried out using completely randomized design with twenty treatments. Each treatment included two APPLE trees with three replications in Torough Station of Agricultural Center of Khorasan on the APPLE trees during 2002. Treatments were: T1= control (without P use), T2= using P as triple superphosphate, T3= 40% concentrated RP + 40% sulfur + 16% cow manure (CM) + 4% zinc sulphate, T4 = T3 + 20 grams THIOBACILLUS inoculant, T5= T3 + 40 grams thiobacillus inoculant, T6= T3 + tea residues instead of CM, T7 = T4 + tea residuse instead of CM, T8 = T5 + tea residues instead of CM, T9= T3 + compost instead of CM, T10 = T4 + compost instead of CM, T11 = T5 + compost instead of CM, T12 = 50% concentrated RP + 30% SULFUR + 16% CM + 40% zinc sulfate, T13= T12 + 20 grams THIOBACILLUS inoculant, T14 = T12 + 40 grams thiobacillus inoculant, T15 = T12 + tea residues instead of CM, T16= T13 + tea residues instead of CM, T17 = T14 + tea residues instead of CM, T18=T12 + use of compost instead of CM, T19= T13 + use of compost instead of CM, and T20 = T14 + use of compost instead of tea residues. In all treatments mentioned, 1 kg of each fertilizer was applied to each tree at 40 cm depth, by deep placement method. The results indicated that there were significant differences between available P concentration in deep placement method and P levels of leaves in treatments which included concentrated RP + SULFUR, THIOBACILLUS bacteria and CM, compared with control treatment and treatments with no THIOBACILLUS. Based on the results, it seems that (P<5%), GOLDEN BIOPHOSPHATE can be used at the rate of 1 kg/tree in APPLE orchards, instead of triple superphosphate fertilizer.
