Abstract
Abstract Symptoms of fusarium wilt of tomato were less severe in plants supplied with nitrate-N and greater in those supplied with ammonium-N. Liming with calcium hydroxide decreased disease severity but this effect was negated by high ammonium-low nitrate fertilization. The combination of high nitrate, low ammonium, and lime reduced disease development additively. Fusarium oxysporum f. sp. lycopersici race 2 was more virulent when grown in liquid culture with ammonium than with nitrate as the sole N source.
