Abstract: Two Field experiments on potato (Solanum tuberosum, L. cv.Diamont) crop were carried out at El-Qanater Horticultural ResearchStation, Kalubiya, Governorate, Egypt located at lat. 30.11, long 31.60and 14.00 m above the mean sea level during two successive seasons2010 and 2011. The study concerned the use of different rates ofanhydrous ammonia (100 and 120 kg N/fed.) with foliar application ofzinc and manganese or both on potato crop in alluvial soil. Generally,in most cases,The high anhydrous ammonia level (120 kg N/ fed.) wasincreased significantly dry matter of potato plant at 90 days fromplanting and nitrogen & phosphorus content as well as dry weight oftuber/ plant (g/plant), fresh & dry tuber yield/fed., N, P, K, Zn and Mncontents of tuber compared to low anhydrous ammonia level (100 kgN/ fed.) of both seasons.Generally, the most parameters in this investigation wereincreased significantly when the treatment of foliar application withmixture of Zn and Mn was carried out in both seasons. In contrast, thelowest ones were recorded by the control treatment (without foliarspray) followed by sole foliar spray with Zn or Mn in two seasons.Finally, the best significant values of most parameters wereobtained by interaction between foliar application with mixture of Znand Mn under the high anhydrous ammonia level (120 kg N/ fed.).Meanwhile, the lowest ones were observed when control treatment(without foliar spray) with the low anhydrous ammonia level (100 kgN/ fed.) was practiced of both seasons.
