| Abstract: | The effect of two irrigation methods, microjet mist and impact sprinkler, on the total glycoalkaloid (TGA) and nitrate-nitrogen (NO3?N) content ofSolanum tuberosum L. cv. Rosa was investigated. Potatoes irrigated by microjet mist were significantly higher in TGA and lower in NO3?N content than control potatoes receiving no irrigation. The impact sprinkler method produced potatoes significantly higher in NO3?N than controls. The TGA content of potatoes irrigated by the sprinkler method was not significantly different from controls. Mist-irrigated potatoes were higher in TGA and lower in NO3?N content than sprinkler-irrigated potatoes. |
