Effects of nitrogen fertilizer and super absorbent polymers on yield of Avena sativa cv. Qingyan No.1

Effects of super absorbent polymers type and dosage and the nitrogen fertilizer on oats yield and hay production in different growth stages were studied with orthogonal design with 3 factors and 3 levels at arid and semi-arid region. The results showed that the influence on oats yield decreasing in the following order: nitrogen fertilizer, super absorbent polymers dosage and super absorbent polymers type. The optimal treatment was Soil Conditioner Warer with dosage of 60 kg·ha-1 and 60 kg·ha-1 nitrogen fertilizer which can increase the yield, yield performance and economic benefit of Avena sativa cv. Qingyan No.1.
