Effect of gypsum, boron and potassium on peanut yield, its oil contents and chemical properties

الملخص EN

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 13th, 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.
