继腰果种植者抱怨尼日利亚西南部濒临死亡的腰果种植园腰果苗成苗率低之后，在尼日利亚伊巴丹进行了一项化肥试验，试验使用有机材料(牛粪、家禽粪便、可可和可可豆壳)与NPK和对照(不施肥)处理，以研究腰果幼苗的生长表现。氮肥施用量为15g/L，分3次重复。测定了腰果苗期生长参数和干物质产量。与NPK和对照相比，施肥量普遍较高，株高、周长、叶片数和叶面积均较高。株高、叶片数和叶面积的平均值差异不显著，而株高、叶数和叶面积的平均值差异显著(P≤0.5)，而分枝数没有明显的规律性趋势。施有机肥的植株根长显著高于NPK和对照。植株叶、茎、根和总干物质产量的干重值也有类似的趋势。然而，与对照相比，所有参数对NPK使用量没有一致的显着影响。由此可见，使用有机肥比使用无机肥更有利于腰果苗木的生长和成苗。使用可可豆壳，然后使用牛粪和家禽粪便，在腰果苗木的生长和干物质产量方面表现突出，建议用于此目的。
Sequel to complaints by cashew farmers on poor establishment rate of cashew seedlings on rehabilitated moribund cashew plantations in south western Nigeria, a fertilizer trial involving the use of organic materials (cow-dung, poultry droppings, cocoa and kola pod husks) compared to NPK and control (no fertilizer) treatments was conducted on the growth performance of cashew seedlings at Ibadan, Nigeria. The fertilizers were applied to supply 15 g N seedling -1 in 3 replications. Cashew seedling growth parameters and dry matter yield were determined. Fertilizers resulted to consistently general higher plant height, girth, number of leaves and leaf area compared to NPK and control. The differences in the mean values were however not significantly different for girth but it was significant (P ≤ 0.5) for plant height, number of leaves and leaf area, while there was no particular regular trend for plant number of branches. Plant root lengths were significantly higher using the organic fertilizers than NPK and control. Similar trend was obtained in the dry weight values for plant leaf, stem, root and total dry matter yield. There was however no consistent significant effect on NPK usage over control for all the parameters. It was therefore deduced that optimal growth performance and better establishment of cashew seedlings could be obtained with the use of organic fertilizers rather than inorganic fertilizer. The use of cocoa pod husk followed by cow-dung and poultry droppings were outstanding in better growth and dry matter yield performance of cashew seedlings and were advised for this purpose.
