Abstract

Two field experiments were carried out to study the effect of gypsum, boron and potassium on peanut crop (Arachis hypogaea L.) cv. Giza 6 grown at Jazerat Abo Amro Village, Abo Kabeer District, Sharkia Governorate, Egypt during 2014 season. The desing of each experiment was a randomized complete block design (3 replicates) factorial with 2 factors. The plot area was 10.5 m². Seeds were sown on May 13^th, 2014. The first experiment was carried out to study the effect of gypsum application and foliar spray application of boron on peanut. The two factors were : gypsum addition with 4 treatments 0, 600, 1200 and 1800 kg ha^-1. 2: Foliar B spray with 3 treatments of 0, 72 and 144 g B ha^-1. The second experiment was carried out to study the effect of gypsum and potassium application. The factors were 1: gypsum 3 treatments of 0, 600 and 1200 kg ha^-1. 2 : K addition at 0, 48 and 96 kg K ha^-1. Results of the first experiment showed that seed yield was increased with gypsum increase up to 1200 kg ha^-1 and without B foliar spray. Seed oil increased due to application of 600 kg ha^-1 + 48 g B ha^-1. Seed yield increased with 1200 kg gypsum ha^-1 + 96 g K ha^-1. The seed oil content was the best at gypsum rate of 600 kg ha^-1 + B 48 kg K ha^-1.
