A field study was conducted to evaluate the date of sowing of groundnut (<italic>Arachis hypogaea</italic> L.) during <italic>kharif</italic> 2009 and 2010. Experiment was laid out in split-plot design by assigned dates of sowing (20 April, 15 May, 9 June and 4 July) and varieties ('HNG 10' and 'TG 37A' ) in main plots and four fertility levels (without fertilizers, 20 N + 40 P₂O₅, 30 N + 60 P₂O₅ and 40 N + 80 P₂O₅ kg /ha) in

... plots. Yield components of semi-spreading variety 'HNG 10' were statistically at par with each other at different dates of sowing from 20 April to 9 June. Harvest index in both the varieties was observed significantly higher in 4 July sowing. The results of the study showed that significantly higher crop stand at harvest was observed in 9 June and 4 July sowing than all other sowing dates and variety 'TG 37A' flowered significantly earlier than 'HNG10'. Significantly higher yields were recorded in 30 kg N+60 kg P₂O₅ /ha which was statistically at par with 40 kg N+80 kg P₂O₅ /ha. On the basis of economics, variety 'HNG 10' of groundnut recorded significantly higher net re urn ( 61843/ha) when sown on 9 June.
