Two field experiments were conducted in a private farm at EL-Ismailia Governorate in two successive summer seasons of 2006 – 2007 to study the effect of application of gypsum, humic acid and foliar ascorbic acid at rates of 250 and 500 ppm on some nutrients uptake and peanut productivity (Arachis hypogaea L cv. Giza 6). The gypsum was added to the soil at a rate of 500 kg fed^-1 before sowing. Nitrogen, phosphorus and potassium fertilizers were applied at the recommended doses. Humic acid was mixed thoroughly with water (2kg / 100 L of water). The mixture was applied at a rate of 5ml /L after 30 days from sowing and repeated two months later.  Ascorbic acid was applied at rates of 250 and 500 ppm and sprays after 25 and 50 days after seed sowing and the spraying solution volume was 200 L fed^-1.   Results showed that the application of gypsum + humic and ascorbic acid at rates of 250 and 500 ppm led to increase seed and straw yields. The values of seed yield were ranged from 540 to 1202 kg fed^-1  , weight of pod , 817 to 1576 kg fed^-1 , weight of 100-seed 62.15 to 74.47 and weight pods  130.31 to 231.29 g  for those treated with gypsum +humic acid + ascorbic acid at rates of 250 and 500 ppm compared with control in both seasons. Seed oil (%) showed a significant difference for all the applied treatments compared with control (NPK recommendation). Macronutrients and micronutrients uptake in seed and straw increased with increasing ascorbic rates from 250 t0 500 ppm, particularly when combined with gypsum and humic.
