| Abstract | ||||
| Two Field experiments on potato (Solanum tuberosum, L. cv. Diamont) crop were carried out at El-Qanater Horticultural Research Station, Kalubiya, Governorate, Egypt located at lat. 30.11, long 31.60 and 14.00 m above the mean sea level during two successive seasons 2010 and 2011. The study concerned the use of different rates of anhydrous ammonia (100 and 120 kg N/fed.) with foliar application of zinc and manganese or both on potato crop in alluvial soil. Generally, in most cases, The high anhydrous ammonia level (120 kg N/ fed.) was increased significantly dry matter of potato plant at 90 days from planting and nitrogen & phosphorus content as well as dry weight of tuber/ plant (g/plant), fresh & dry tuber yield/fed., N, P, K, Zn and Mn contents of tuber compared to low anhydrous ammonia level (100 kg N/ fed.) of both seasons. Generally, the most parameters in this investigation were increased significantly when the treatment of foliar application with mixture of Zn and Mn was carried out in both seasons. In contrast, the lowest ones were recorded by the control treatment (without foliar spray) followed by sole foliar spray with Zn or Mn in two seasons. Finally, the best significant values of most parameters were obtained by interaction between foliar application with mixture of Zn and 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 kg N/ fed.) was practiced of both seasons. | ||||
