Abstract
Groundnut (Arachis hypogea L.) is an important oilseed crop of the world. It is being grown in tropical and subtropical regions between 40°N and 45°S latitude. Abiotic and biotic stresses are the constraints to enhance the yield. Next to drought, nutrient stress is affecting the yield. In India more than one third of the soil is calcareous. Lime induced iron chlorosis (LIIC) in groundnut is common in calcareous soil due to non availability of iron. Iron deficiency had a remarkable effect on growth and development and reduces allocation of assimilates to the reproductive organs through decreased pod set and seed growth rate. Under LIIC, younger leaves show yellowing in inter-veinal areas leading to 12- 24 % reduction in pod yield. It is one of the constraints for low productivity in Karnataka also. There is a need of groundnut which can withstand LIIC and yield more under low soil iron availability. Hence, diverse genotypes were evaluated in calcareous soil to identify an iron efficient ideotype with morphological background.
