研究了刈割间隔和施肥对王草营养品质、养分吸收和生物量的影响。实验设计是一个随机化的完全区组，使用4个区组和8个处理，每个区组的处理包括4个年龄的切割（30，45，60和90天），施肥和不施肥。结果表明，施肥后干物质增加了72，000 kg ha−1 year−1。随着刈割天数的增加，蛋白质含量显著降低（12.70-6.53%）。随施肥处理和刈割天数的增加，纤维含量增加（48.79-72.99%）。施肥中所含的元素（N、P、K）表现出较高的叶片含量，并且随着植物的生长，叶片含量也呈现出减少的趋势。施肥处理显示，所有元素的养分吸收增加到60天，在那里的吸收能力减少观察。王草是一种具有高养分吸收能力的植物，因此具有高生物量和养分产量。这是一个优点，因为它可以用于多种应用，例如动物饲料，生物燃料生产，以及作为生物消化的底物等。
The research was conducted to determine the effects of cutting interval and fertilization on the nutritional quality, nutrient uptake, and biomass production of King grass. The experimental design was a randomized complete block, using 4 blocks and 8 treatments per block; treatments consisted of 4 ages of cutting (30, 45, 60, and 90 days), with fertilization and without fertilization. The results showed increases of up to 72,000 kg ha−1 year−1 of dry matter (DM) when fertilization was implemented. There was a significant reduction in with an increase in the cutting days (12.70–6.53% protein). Fiber increased (48.79–72.99% NDF) when fertilization treatments were included and cutting days increased. The elements that were included in fertilization (N, P, K) showed a higher foliar content and also presented a reduction in foliar content with growth of the plant. Treatments with fertilization showed a nutrient uptake increase for all the elements up to 60 days, where a reduction in uptake capacity was observed. King grass is a plant with a high nutrient uptake capacity and, therefore, with high biomass and nutrient production. This is an advantage since it can be used in multiple applications, such as animal feed, biofuel production, and as a substrate for biodigestion, among others.
