Abstract
Two field experiments were carried out at the private Farm in Basandela Village, Belqas, Dakahlia Governorate during the two successive summer seasons of 2012 and 2013 to study the response of potato (c.v. Valor) growth and yield to some stimulating compounds i.e, Thiamine(V.B1)100 ppm, Riboflaphine(V.B2)100 ppm, Ascorbic acid (V.C)100 ppm, Decenyl succinic acid (DSA) 400 ppm, Arginine acid 400 ppm, Proline acid 400 ppm and Micronutrients (Fe, Zn and Mn) each 75 ppm .
Results indicated that plant height and number of leaves/plant were significantly increased with application of Decenyl  saccinic  acid (DSA) compared with other treatments in both seasons of study.  Number of branches/ plant and number of stoolens /plant were significantly increased with application of proline acid compared with the control.  Leaf area was significantly increased with foliar application of Ascorbic acid in both seasons of study.
Total yield (tones / fed.), average tuber weight and marketable yield of tubers were increased significantly with application of  Ascorbic acid (100 ppm) followed by the Arginine acid compared with other treatments. The foliar application of Arginine acid increased the content of tuber from N%,P% and K%  in both seasons of study compared with the other treatments. On the other hand, all treatments significantly decreased the content of No3=  and  No2=   in the tubers at harvest compared with the control treatment while, the lowest values of  No3=  and  No2=  had beenobtained after the foliar application of  Arginine acid in both seasons. Therefore, this treatment could be recommended for raising potato production and quality under similar conditions to this work.
