GARGANTINI, H.; LEITE, N.; HUNGRIA, L. S.  and  VENTURINI, W. R.. Effects of micronutrients on potato crops production in hidromorfic soils of Paraíba Valley. Bragantia [online]. 1970, vol.29, n.unico, pp.1-10. ISSN 0006-8705.

The influence of the micronutrients iron, copper, zinc, molybdenium, manganese and boron added to the basic fertilizer on yield and quality of potato (Solatium tuberosum L.), growing on alluvial soils was studied. An increase in the yield of 40% in soils of Avareí series and 50% of Paraiba series, was associated with application of boron and molybdenium to the soil. The effect of boron was much more pronounced than that of molybdenium. Application of iron, copper, zinc and manganese have no significant effect on potato yield.
