The groundnut (Arachis hypogaea L.) is an important legume food crop in India that is grown on about 8 m ha of land. The average productivity of groundnut in India is around 1300 kg ha-1 which used to be around 1000 kg ha-1 in the last decade. However, the demand of groundnut as oilseed and food crop is increasing. The low productivity in India is mainly due to the fact that the crop is mostly grown rain fed on dry lands and in semi-arid regions with low fertility and input management resulting in nutrient deficiencies particularly in Zn. In India, about 50% of the groundnut soils show Zn deficiencies causing considerable yield losses (Singh 1999, Singh et al. 2004). Thus, pot and field studies on Zn were initiated at our institute about a decade ago. Some of the findings are summarized here.
