e0“Rainfall in the northeastern United States can be erratic, causing fluctuations in the supply and quality of potato ( Solanum tuberosum L. )”
e6“Irrigation treatments significantly increased total yields by 10 t ha −1 (36%) in 1994 and 11.6 t ha −1 (37%) in 1995, while significantly reducing specific gravity and increasing tuber size”
