Studies on the effect of different sources of nitrogen at different times of application on the yield of potato



Studies on the effect of different sources of nitrogen at different times of application on the yield of potato



Journal of Agricultural Research, Pakistan 8(3): 252-257



Potato Utilla was given 0, 60, 90 or 120 lb N/ac as ammonium sulfate, ammonium nitrate or urea at planting or at the 3- to 5-leaf stage. Tuber yields increased with increasing rates of N and mean yields were highest when N was applied at the 3- to 5-leaf stage.
