The tril ws conducted in form of split plot sed on rndomized complete lock design with three replictions. This experiment ws crried out with 3 fctors which were included: usge of ure chemicl fertilizer s the min fctor in 5 levels: (control: without using ure, 25, 50, 75 nd 100% of recommended mount sed on soil test); consumption of Nitroxin iologicl fertilizer s suordinte fctor in 2 levels: ( 10 nd 20 liters per hectre) nd consumption of vin enriched orgnic mnure () s su-suordinte fctor in 2 levels (soil usge efore plnting t rtes of kg nd kg per hectre). In this study, tuer weit per plnt, weit of tuer smller thn 35 mm, etween mm nd lrger thn 55 mm, yield of mrketle tuers per re unit nd tuer yield per re unit were evluted. The results demonstrted tht there were significnt differences for ll studied trits t interction of mnure chemicl fertilizer levels nd three-wy interction of ure chemicl fertilizer levels of Nitroxin iologicl fertilizer levels of mnure. Yield of mrketle tuer nd tuer yield with consumption of 10 liters Nitroxin fertilizer incresed out 0.45% nd 0.22%, respectively; in comprison with 20 liters. Yield of mrketle tuer nd tuer yield in 75% recommended mount of ure chemicl fertilizer sed on soil test indicted ugmenttion out 5.58% nd 4.92%, respectively; in comprison with control tretment. Amount of mrketle tuer yield nd tuer yield in A 1 B 1 C 1 compound s compred with A 4 B 1 C 2 compound were more out 8.32% nd 6.42%, respectively. Keywords: Solnum Tuerosum, Biologicl Fertilizer, Nitrogen, Nitroxin, Avin Mnure, Tuer Yield INTRODUCTION Potto is elonged to Solnum genus nd Solncee fmily. Agronomic potto is from Solnum tuerosum species nd uto-tetrploid with genomic formul of 2n=2x=48. This is the only tumorous species of Solnum genus which is cultivted outside of its ntive region (Arzni, 1387). Potto is from flowering hier plnts, dicotyledon clss, Solncee fmily nd Solnum genus which is cultivted to use its underground tuer (Rezi nd Soltni, 1380). Potto is vlule foodstuff which is regrded s one of the importnt crops. This crop hs hi nutritious vlue due to presence of strch nd essentil mino cids; prticulrly vitmins B nd C which re necessity for humns (Hssnpnh et l., 1387). From the view point of potto production, Irn hs 12 th rnk in the world nd is the third-lrgest producer in Asi fter Chin nd Indi (FAO, 2011). This crop is prticulrly importnt for developing countries ecuse of its hi potentil per re unit nd per time unit nd hs more nutritionl vlue in order to mintin of growing popultion with mlnutrition nd hunger in the world (Rezi nd Soltni, 1380). Its nnul production in Irn with more thn 4.5 million tons is in third rnk fter whet nd rice (Hssnpnh et l., 1383). In the pst few decdes especilly in the lst hlf century, due to popultion growth nd demnd ugmenttion for supplying food; chemicl fertilizers hve een overused in severl regions to rech mximum production per re unit. Of course, it mkes numerous prolems in humn helth nd environmentl pollution (Qoshchi et l., 1385). Appliction of iologicl fertilizers hve positive effects Copyrit 2014 Centre for Info Bio Technology (CIBTech) 26

2 on ll soil properties, in ddition; it ecme pproprite from the view point of economic, environmentl nd socil thus it cn e used s desirle sustitute for chemicl fertilizers (Kuchki et l., 1379). Selection of fertilizer mngement depends significntly on environmentl progrms for prevention of pollution in lnd nd wether, therefore pproprite system of fertilizer mngement is worthy to expnsion (Krmk et l., 2007). Appliction of orgnic mtter in form of mnure increses levels of soil orgnic cron nd hve direct nd indirect effects on properties nd processes of soil (Prksh et l., 2007). Overuse of chemicl fertilizers is one of the importnt chllenges for griculture. Consequence of overuse in phosphte fertilizers is excessive ccumultion of phosphorus; in ddition, it cused to crete competition in sorption of nutritious elements especilly zinc (Zn), resources dissiption, decrement in popultion of mycorrhiz fungi nd lso more importnt of ll, excessive ccumultion of cdmium in crops. Thus with excessive consumption of phosphte fertilizers, toxic elements like cdmium sor y plnts nd enter to food chin of humns nd nimls. Use of iologicl fertilizers with reduction in consumption of chemicl fertilizers nd lso decrement in production costs nd environmentl pollution due to use of chemicl fertilizers, is one of the min strtegies for chievement to sustinle griculture (Byurdi nd Mlkuti, 1380). Approprite nd idel conditions for plnt growth re provided with use of chemicl nd iologicl fertilizers in form of integrtive. So tht, not only there is no ntgonism effect etween them, ut re complementry to ech other. Orgnic fertilizers with humus production decline the hrmful effects of chemicl fertilizers nd increse fertilizer use efficiency. Biologicl fertilizers with increment in ctivity of plnt growth increser cteril ugment effects of chemicl nd orgnic fertilizers in griculturl production (Zhng et l., 1998; Sht et l., 2007). In survey conducted y Eyvzlu et l., (2009) the effect of erthing up nd rvr-2-phosphte s iologicl fertilizer with folir ppliction of micronutrients on potto yield, demonstrted tht the hiest yield of tuer ws otined in twice erthing up with use of rvr-2-phosphte nd folir ppliction of ferrous sulfte. Ghodi et l., (2011) in ssessment of phosphte fertilizers impct on yield nd yield components of pottoes indicted tht simultneous ppliction of phosphte solvent cteri nd inorgnic phosphtes ws effective on vilility nd soluility of phosphorus on soil. During investigtions y Soug et l., (2010), it ws oserved tht use of orgnic nd inorgnic fertilizers cused significnt differences on eggplnt growth, yield nd fruit qulity in comprison with other tretments. Nmur et l., (2012) in effect evlution of nitrogen fertilizer nd iologicl mnure on yield, grin yield components nd oil of sunflower, declred tht the hiest level of nitrogen fertilizer nd inoculted iologicl fertilizer cused to the mximum plnt heit, stem, hed dimeter, numer of grins per hed, 1000-gins weit. Ddshzdeh et l., (2013) reported tht the control tretment (no Nitroxin iologicl fertilizer) in comprison with tretments of fertilizer consumption hd lower plnt heit, numer of min stems per plnt, numer of tuers per plnt nd dry mtter percentge. Tretment of 20 liters per hectre s compred with 10 liters per hectre hd lower stem dimeter, weit of tuers per plnt nd tuer nitrte. The purpose of this study ws to evlute the effect of orgnic nd nitrogenous iologicl fertilizers t different rtes nd reduced nitrogenous fertilizer on tuer yield of potto Agri vriety. MATERIALS AND METHODS This reserch ws performed in cropping yers of t Shriyn city locted in Mehren of Sr County in the field with re of 1200 squre meters. Sr desert ws locted in Est Azrijn province nd Sr County, etween two mountins of Sln nd Bozgoush t longitude of 47 32ʹ, ltitude of ʹ nd 1682 meters heit from se level (Tle 1). Soil texture ws sndy - lomy nd surfce soil hd 40% rock or grvel, 46% silt nd 36% cly. Pen trnce of these soils ws quick nd its dringe ws nturl nd perfect (Tle 2).
