A field experiment was carried out in one of farms in Babylon distract Abi Garaq of a 10 am soil texture , to study the effect of organic fertilization application ( poultry wastes) and foliar application of humic and folric acid )and interaction between them on the growth and yield of Potato . This experiment included three levels of organic fertilizer ( poultry wastes ) at 0 , 5 , 10 Ton.ha-1 . First factors named F0 , F1 , F2 respectively , while the second factors of foliar application of organic acids ( humic and folvic acid ) named as S0 , S1 , S2 at 0 , 5 , 10 ml.L-1 respectively at a total of nine treatment in three application of a total experimental units of 27 . They experiment was carried out under RCBD , Potato tubers class Burren were planted on 16 / 1 / 2017 .At maturity ,  total percentage of proteins and starch of the total yield and tubers number at the end of season were measured. Data was statistically analyzed and means were compared according  to least signification different test at 0.05 level of probability . Result show :- Organic fertilization ( poultry wastes ) F2 was supervisor as compared to F1and F0 in plant  total tubers yield 28.70 Mg ha-1 , number of tubers 6.96 tuber plant-1 , total tuber dry weight percentage 28.70%.Organic fertilization of poultry wastes , treatment F2 was superior when compared to F1 and F0by giving the highest percentage of protein and starch tubers at 10.19% and 11.0 % respectively . Foliar application of organic acid ( humic and folivc ) have shown super iorvity in studied  porameters of  F2 treatment when compared to S1, S0 treatment where it caused a signification increase in  total tubers yield , number of tubers , at highest values of means at  25.29 Mg ha-1 , 7.82 tuber . per 17.73 %  of each respectively .Organic acids foliar application treatment S2 was superior to S1 , S0 by giving highest means of protein and starch percentage in tubers at 9.56 , 11.71% respectively . F2S2interaction treatment has given the highest values of studies parameter where they were  10.31 % , 12.43 % of protein and starch percentage in tubers respectively . 4. 30.73 M gm ha-1 of total yield of tubers , 8.83 tuber plant-1 .

To investigate the effects of manure (plants residue) on growth and yield of potato in calcareous soil, afield experiment were conducted in field located in physical education college areas Baghdad University – Jadiriyah campus in fall season 2015-2016 in a sandy loam soil, Included two factors first factor is four serous of manure O0 (without application) O1( poultry) O3( wheat straw) O3 (palm fronds) with 30 Ton h-1, Second factor application three level of mineral fertilizers (without application) M0 (120 N + 60 P + 200 K ) M1 (240 N + 120 P + 400 K ) Kg h-1 layout in ( RCBD) with three replication, manures and phosphate fertilizer were added two week per planting, seed of potatoes class (Desiree) planted on 22 September 2015, adding nitrogen and potassium fertilizer in three equal 21,45 and 70 days after planting, on 22 January 2016 at maturity stage, tubers from five plants in each medium rows harvested to determine total tuber yield, concentration of N, P and k in dry mass tubers were determined, Results showed a superiority treatment of poultry gave 49.94 Ton h-1 and highest concentration of N 2.06%, P 0.32% and 2.66% K, M2 treatment gave highest total tuber yield 50.20 Ton h-1 and 2.05 % N, 0.36% P and 2.54% K. interaction treatment M2O2 gave 57.22 Ton h-1 total tuber yields and 2.19%, 0.39% and 2.57% concentration of N, P and K in tubers respectively

A field experiment was conducted in one of the farmers' field in Jabla district Babylon  province in the autumn season 2016 using potato cultivar the Burren  , the experiment was included  two factors, the first factor was organic manure with six treatments: 32 tons.ha-1 of Palm fronds wastes,  32 tons .ha-1 of rice wastes ,،a kon . f waste with  manure in six treatments >of two factors  16 tons .ha-1  of palm fronds wastes. 16 tons .ha-1 of rice wastes, palm fronds wastes  with humic acid  , rice wastes with humic acid , rice wastes with palm fronds wastes  with humic acid ,in addition to chemical fertilizer 600 kg . ha-1.(NPK) , and Urea fertilizer 400 kg .ha-1.,in addition to the comparison treatment . the second factor  was bio-fertilizer  with two treatments Mycorrhizeae fungi with 10  gm . plant-1   ,trichoderma fungi with 0.625 gm . plant in addition to the comparison treatment  . the study was conducted as factorial experiment according to the randomized complete block design(RCBD). each treatment  with 3 Replicates. The results showed that the treatment of the mixing of palm fronds wastes and rice wastes and humic acid and chemical fertilizer treatment gave significant differences in the paper area while the treatment of adding rice waste achieved the highest rate in the plant height and the total number and the marketing share reached 63.66 cm and 38.61 ton.ha-1 and 37.65 ton . ha-1 respectively. While the bio fertilizers achieved significant differences in the total yield and the marketing yield. The treatment of the addition of the Trichoderma gave the highest rate (37.16 and 36.16 ton.h-1) respectively. The overlap between the two types of fertilizer achieved significant differences the height of the plant and the total and the marketing yield, Percentage of dry matter and percentage of starch in tubers.
