Abstract
Trials have been conducted since 1968 at the Volcani Center and the respective Regional Research Stations in an attempt to solve the problem of lime‐induced iron deficiency and connected reduction of yield that occurs when peanuts are cultivated on basic and calcareous soils. Different iron compounds and micronutrient solutions were tested for their effect on yield and quality of the commercial peanut variety presently grown in Israel. A highly favorable response was obtained to iron chelates, namely, Fe‐ethylene diamine‐di(o‐) hydroxy‐phenyl acetic acid (FeEDDHA) with the recommended rate being 10 to 15 kg/ha. The peanut collection of the Volcani Center was screened in order to isolate iron‐absorption‐efficient genotypes. Consequently, lines 71–234 and 71–238, Virginia‐type peanuts, were found to be relatively more iron‐absorption‐efficient than the standard (control) variety “Shulamit.”
