Moghat plants, Glossostemon bruguieri, Desf., received three levels of both N and K fertilizers, either alone or in combination, with a basic dose of P for all the treatments. The results with one and two year old plants revealed the importance of potassium for higher yield of roots, reflected in greater length and diameter. The lower level K1 was enough to attain that goal and the N1K1 treatment was the best in this regard. On the other hand, N fertilization rather favoured the vegetative growth and seed yield. Both N and K fertilization decreased the mucilage content of the roots, but increased their fat content. The root yield after two years increased by 72% compared with one year old plants. That increment was rather dependent on the root diameter than its elongation. The mucilage content was doubled, while the fat content decreased.
莫加特植物（Glossostemon bruguieri, Desf.）接受了氮和钾肥料的三个水平，单独施用或组合施用，并对所有处理都施用了基本剂量的磷。对一年生和两年生植物的研究结果表明，钾对提高根产量很重要，这体现在根的长度和直径更大。较低水平的K1就足以实现这一目标，在这方面N1K1处理是最好的。另一方面，氮肥更有利于营养生长和种子产量。氮和钾施肥都降低了根的黏液含量，但增加了根的脂肪含量。两年后的根产量比一年生植物增加了72%。这种增加更多地取决于根的直径而不是伸长。黏液含量增加了一倍，而脂肪含量降低了。
