ABSTRACT
Effect of three major mineral supplements (NPK) on sex expression of fluted pumpkin, Telfairia occidentalis Hook F. was investigated. The potassium containing nutrient supplements K, NK and PK promoted staminate flowering or caused a shift toward maleness while nitrogen and phosphorous containing nutrient supplements (N, P, NP and NK) promoted pistillate flowering or caused a shift toward femaleness. The influence of mineral nutrients on the hormonal balance for sex expression in the species is discussed.
