摘要
在尼日利亚西南部森林-稀树草原过渡带abobokuta农业大学教学与研究农场(7015′N, 3025′e),于1999年和2000年雨季后期进行了田间试验,调查了向日葵(vr. N .)施氮(0、30、60和90公斤N公顷-1)和磷(0、30和60公斤P公顷-1)肥。N显著高于对照组(P -1)。与对照相比,施氮(P -1)显著增产30%、40%和50%。氮磷互作显著(P -1),瘦果重(27.99 g)和第二高的穗重(63.76 g)。因此,由于N60P30的施用使向日葵的性能达到最佳,因此,推荐在尼日利亚西南部森林-热带草原过渡带生产向日葵。关键词:氮,磷,向日葵,过渡区,尼日利亚西南部。尼日利亚园艺科学杂志2005年第10卷:第23-29页
Response of sunflower (Helianthus annuus L.) to nitrogen and phosphorus application in the forest-savanna transition zone of south west, Nigeria
Field experiments were conducted during the late rainy-season cropping of 1999 and 2000 at the Teaching and Research Farm of University of Agriculture, Abeokuta (7o15' N, 3o25'E) in the forest-savanna transition zone of south west Nigeria to investigate the response of sunflower (vr. Funtua) to applied nitrogen (0, 30, 60 and 90 kg N ha -1 ) and phosphorus (0, 30 and 60 kg P ha -1 ) fertilizers. N significantly (P -1 compared to the control. N also significantly (P -1 significantly increased grain yield by 30, 40 and 50 %, compared with the control. Nitrogen x Phosphorus interaction significantly (P -1 ), achene weight (27.99 g) and second highest head weight (63.76 g). Consequently, it was concluded that since application of N60P30 resulted in optimum performance of sunflower, these rates are therefore, recommended for sunflower production in the forest-savanna transition zone of south-west Nigeria.
