Abstract: This study was carried out with the objective to determine the most suitable sowing time for groundnut under rainfed conditions during cropping seasons of 2013 and 2014. The trials were conducted in the field area of Groundnut Research Station Attock. The experiment was laid out according to triplicate randomized complete block design with split plot. Planting dates (20 March, 30 march, 10 April, and 20 April) were kept in main plots while cultivars (BARI-2011, 10AK020 and 10AK016) in subplots. All the fertilizers were applied at the sowing time while Gypsum was applied at peg formation stage. Crop was grown under rainfed conditions and was harvested at physiological maturity. The results showed that the most suitable planting date for genotype 10AK016 was 30th March while 10th April for BARI 2011 and 10AK020 as maximum pod yield, pod length and pod weight were recorded for this sowing time. Delay in sowing of groundnut beyond 10th April had negative effect on yield and yield attributes. So sowing of groundnut should be completed before 10th April under climatic conditions of Attock as high temperatures and drought stress occurs during peg formation and pod development and maturation periods causing significant decline in pod yield.
