An investigation on effect of sowing time on growth, phenology and yield attribute of summer groundnut (Arachis hypogaea L.) was conducted at Agrometeorological Station Farm, School of Forestry and Environment, SHIATS-Deemed-To-Be-University, Allahabad during crop season 2013. Sixteen treatment combinations with four dates of sowing (1st March, 11th March, 21st March and 31st March) and four varieties (HNG-69, R-2(Girnar-2), HNG-10 and M-13) were tried in split plot design with four replications. The crop yield showed negative and highly significant correlations with average weathers parameters viz., maximum temperature, minimum temperature during early crop growth phases especially flowering and pegging period and the morning relative humidity, afternoon relative humidity during later crop growth phases especially pod maturity period. The crop yield showed negative and highly significant correlations with accumulated agrometeorological indices viz., growing degree days (GDD), photothermal unit (PTU), hygrothermal unit I, photo temperature and nycto temperature during early crop growth phase especially flowering period and positive during pod maturity phase, except GDD, PTU, HgTU-I and HgTU-II. The optimum maximum temperature during flowering (P3) and pod maturity (P5) phases were found to be 41.9 0C and 36.6 0C, respectively.
