Abstract : An investigation was conducted to identify the influence of zinc and sulfur on the prevalence and intensity of Hemicriconemoides mangiferae populations infesting mangoes in Uttar Pradesh, India. Each soil sample was collected at three vertical depths, 0-20, 20-40 and 40-60 cm. The data on functional linear regression trends confirmed the uniform inverse relationships at almost all the depths and distances with zinc content of the soil while positive relationships with sulfur was observed at all the depths and distances with few exceptions at 20- to 40-cm vertical depth and at 90-cm horizontal distance (r=-0.035; P>0.915) during 2000-01; at 40- to 60-cm vertical depth and at 30-cm horizontal distance (r=-0.031; P>0.923) and at 20- to 40-cm vertical depth and at both 60- and 90-cm horizontal distances (r=-0.256; P> 0.421; r=-0.135; P>0.675) during 2001-02.
