Kenaf plant maturity at harvest not only influences the total biomass harvested but also the composition and quality of the plant components. In a 3-yr field study at Lane, Oklahoma with ‘Everglades 41’, plants were harvested at either 60, 90, 120, or 150 days after planting (DAP) (Bledsoe and Webber 2001). Harvest age did not significantly affect plant populations, but did have a significant affect on all other yield parameters.
Averaged across years, the total biomass yields increased from 60 DAP (5.7 t/ha) to 150 DAP (21.0 t/ ha). Although the growth rates did level off or even decrease after 120 DAP, the significant increase in stalk yields after 120 DAP justify the additional 30 days of growth for stalk production. Stalk yields ranged from 3.8 mt/ha for 60 DAP to 19.3 mt/ha for 150 DAP. The percentage of leaf biomass (32%, 60 DAP to 12%, 150 DAP), and leaf digestible protein (18.3%, 60 DAP to 15.5%, 150 DAP) decreased with each harvest date. Leaf yields increased from 2.4 t/h

洋麻植物成熟在收获不仅影响总生物量被收获的，而且植物组分的构成和质量。 在3年现场研究中在车道， 俄克拉何马与`沼泽地41’， 植物被收获了在二者之一60， 90, 120, 或150天在种植以后(DAP) (Bledsoe和Webber 2001)。 收获年龄没有极大影响植物群体， 但有一个重大影响在其他出产量参量。
横跨几年平均， 从60 DAP增加的总生物量出产量(5.7 t/ha)对150 DAP (21.0 t/ ha)。 虽然生长率成了水平甚至在120 DAP以后减少了， 在120 DAP辩解另外的30天成长为茎生产之后，在茎的重大增量产生。 茎出产量从3.8 mt/ha为60 DAP到19.3 mt/ha范围为150 DAP。 叶子生物量(32%的百分比， 60 DAP到12%， 150 DAP)， 并且叶子易消化蛋白质(18.3%， 60 DAP到15.5%， 150 DAP)减少与毎丰收日。 叶子出产量从2.4 t/ha (60 DAP)和4.0 t/ha (90 DAP)增加了对4.4 t/ha在120 DAP然后减少了对3.9 t/ha为150 DAP收获。 另外的研究评估的洋麻作为潜在的饲料作物也确定植物的年龄在收获影响了植物构成， 例如叶子百分比和蛋白质含量(Webber 1993a; Bhardwaj和Webber 1994)。 叶子生物量百分比和百分之天然蛋白质被减少当洋麻植物在高度和成熟增加了。 这构成和质量变动发生，因为更低的叶子senesce， 经常生产植物在150 DAP，不用叶子在更低植物茎的二分之一到四分之三。
