Abstract
A field experiment was conducted to examine the effect of organic waste and NPK fertilizers on macro and micronutrients concentration in potato straw and on yield at Nuclear Institute of food and Agriculture Peshawar, Pakistan during 2012. Fifteen treatments of various organic and inorganic fertilizers were applied to potato crop each replicated three times. After harvesting of the crop, potato yield was recorded. For soil fertility analysis 90 soil samples from two depths (015 and 15-30 cm) and 45 straw samples were also collected and analyzed. Fertilizer doses showed significant effect on potato yield and soil fertility parameter. The treatments (Filter cake + full NPK) and (Municipal solid waste + full NPK) showed high yield and significant effect on NPK and micronutrients concentrations in potato straw. The lowest concentrations of micronutrients in soil and potato straw were observed mainly in treatment (PK recommended dose) and control. It can be concluded from this experiment that the conjunctive use of inorganic fertilizers with organic waste further accelerated the beneficial effect of inorganic fertilizers on soil and plants. The treatments (Filter cake + full NPK) and (MSW + full NPK) seemed to be the appropriate dose for sustainable production of potato.

A field experiment was conducted to examine the effect of organic waste and NPK fertilizers on macro and micronutrients concentration in potato straw and on yield at Nuclear Institute of food and Agriculture Peshawar, Pakistan during 2012
The lowest concentrations of micronutrients in soil and potato straw were observed mainly in treatment (PK recommended dose) and control. It can be concluded from this experiment that the conjunctive use of inorganic fertilizers with organic waste further accelerated the beneficial effect of inorganic fertilizers on soil and plants
Laboratory procedure Total nitrogen in Potato straw samples was determined by kjeldhal method suggested by Bremner [9] while total Phosphorous, Potassium and micronutrients was determined by the standard procedure techniques
Summary
Effect of organic waste and NPK fertilizer on micronutrients concentration in soil Organic waste and NPK fertilizer significantly (P ≤ 0.05) affected the micronutrient concentration in soil. The result showed that maximum Zn concentration were found (176.8 and 113.3 mg Kg-1) in the treatment where MSW+ half NPK, Filter cake + full NPK were applied at two soil depth 0-15 cm and 15-30 cm respectively. The highest concentration of Fe (448.6 and 402.6 mg Kg1) was observed in the treatment (FYM + half NPK) at soil depths of (0-15 cm) and (15-30 cm) respectively. High Mn concentrations (14.1 and 12.4 mg Kg-1) were observed in the treatment (Filter cake+ full NPK and FYM + half NPK) at soil depth (0-15 cm) and (15-30 cm) respectively. Effect of organic waste and NPK fertilizer on micro nutrients concentration in potato straw The micronutrient concentration (Zn, Cu, Fe and Mn) in potato straw were significantly (P ≤ 0.05) increased with the organic waste and NPK fertilizers as compared to control and presented in Table.. 1302.7cd 1365.3ab 1339abcd 1346abcd 1315.3bcd 1322.7abcd 1357.3abc 1355.7abc 1376.7a 60.84
