Abstract
Groundnuts cv. Giza were grown in sandy soil in pots and given 30 kg N + 32 kg P2O5 + 52 kg K2O/feddan; 500 kg gypsum/feddan was applied at flowering, pod formation, or in equal split applications at flowering and pod formation and all plants were sprayed twice with 0.1% aqueous ammonium molybdate or zinc sulphate. Seed yields and 100-seed wt were 5.1, 5.5 and 7.1 g/plant and 34.51, 33.72 and 39.09 g in Mo-treated plants, and 5.1, 8.7 and 9.9 g/plant and 38.06, 36.76 and 37.51 g in Zn-treated plants with gypsum applied at flowering, pod formation and in split applications, resp. Seed oil content was not affected by gypsum or trace element treatment. Seed protein content was significantly higher with split applications of gypsum but was not affected by trace element treatment. [1 feddan = 0.42 ha].
