Effect of method of irrigation on the total glycoalkaloid and nitrate-nitrogen content of Rosa potatoes
- 15 Downloads
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.
