Abstract: Abiotic stresses in sandy soil, which include saline water, saline soil, and lack of nutrients, affect the productivity and quality traits of peanuts ( Arachis hypogaea L). Elemental calcium (Ca 2+ ) is necessary for the proper development of peanut pods. This work aimed at comparing conventional Ca and nano-Ca form effects on peanut production and quality traits. Two randomized complete block field experiments were conducted in the 2015 and 2016 seasons. Treatments were control, gypsum plus calcium nitrate Ca(NO 3 ) 2 , Ca(NO 3 ) 2 , and chelated calcium, as well as 100, 75, 50, 25, and 12.5% of Ca(NO 3 ) 2 doses in a nano form. The results indicated that the treatment of gypsum plus conventional CaNO 3 achieved the highest yield and best quality traits, followed by the Ca(NO 3 ) 2 and 100% nano Ca(NO 3 ) 2 treatments. The treatments of the control, gypsum, and 12.5% nano Ca(NO 3 ) 2 had the lowest effect on peanut performance. The conventional treatment of gypsum plus Ca(NO 3 ) 2 resulted in the greatest seed yield (1.6 ton ha −1 ), oil yield (700.3 kg ha −1 ), and protein yield (380.1 kg ha −1 ). Peanuts may benefit from Ca 2+ better by using gypsum as the soil application and calcium nitrate as the foliar application to prevent disorders of Ca 2+ deficiency under sandy soil conditions.
