Abstract

Field experiment was undertaken in private field inAl-ramadi city in the right side of Euphrates river Anbar Governorate – Iraq, in silt loam soil during spring season of 2012.The aims of the experiment were to study the effect of bio-organic fertilizer(prepared by composting mixture of chicken wastes with wheat straw inocuted with some solubilizing phosphate microbes and enriched with 0.46% by weight phosphate rock) phosphatase activation, some yield component and on tuber quality of potato yield. The experiment involved nine treatment among then adding the recommended N,P and K fertilizer for potato(220 kg N, 52 kg P and 167 kg K ha-1 )asa control treatment. The other treatments were the recommended N, K and 1/2 P, N and K fertilizer with and without 1.5% by weight of the soil to the depth of 15 Cm. of solid bio- organic fertilizer, spraying liquid bio-organic fertilizer on foliage of potato plants and soaking potato seeds in the liquid bio-fertilizer before planting.
The results showed that all treatments received solid bio-organic fertilizer were superior in increasing percentages of protein, starch and dry another of potato tuber over the other treatments. Adding recommended N, K and 1/2 P with 1.5% by weight of solid bio-organic fertilizer with or without spraying foliage of potato with liquid bio-organic fertilizer have given the highest and significant means of tuber weight, tuber yield per plant and tuber yield of potato over the control treatment. Moreover, these treatment have given the highest activation of phosphatase enzyme and mean of microbes density in the soil. Soaking potato seeds in the liquid bio- organic fertilizer significantly increased means of tuber yield, tuber weight and tuber yield per plant and insignificant increases in percentages of protein, and dry matter of potato tuber in comparison with some and unsoaked seed traetments.
