Owing to its multiple uses in veterinary medicine, biofertilizers, pest control, etc., the commercial cultivation of neem (Azadirachta indica) has been increasing in various countries. The use of arbuscular mycorrhizal fungi (AMF) and plant by-products (composted leaves and residues of neem and sugarcane) for the propagation of seedlings can be an efficient alternative to stimulate plant growth, reducing the propagation time and conferring increased tolerance of plants to biotic and abiotic stresses. Therefore this study aimed to evaluate the effect of plant substrates and inoculation with AMF on the production of neem seedlings.
Beneficial effects of the application of neem by-products to neem seedlings were observed on most of the variables analysed. However, the treatment with sugarcane cake did not improve the growth of neem seedlings. In general, the inoculation treatments using Glomus etunicatum in the composted neem substrates improved seedling growth.
Neem by-products benefit the growth of seedlings of this plant under greenhouse conditions. Inoculation with G. etunicatum enhances plants growth mainly in substrates with residues of neem leaves, providing an alternative for the production of seedlings of this crop under nursery conditions, which can reduce the need for chemical fertilizers that impact the environment.
由于印楝在兽医学、生物肥料、害虫防治等方面有多种用途，印楝（Azadirachta indica）在各国的商业种植一直在增加。使用丛枝菌根真菌（AMF）和植物副产品（印楝和甘蔗的堆肥树叶及残渣）进行幼苗繁殖可能是刺激植物生长的一种有效替代方法，可缩短繁殖时间并提高植物对生物和非生物胁迫的耐受性。因此，本研究旨在评估植物基质和接种AMF对印楝幼苗生产的影响。
在分析的大多数变量上都观察到了将印楝副产品应用于印楝幼苗的有益效果。然而，甘蔗饼处理并未改善印楝幼苗的生长。总体而言，在印楝堆肥基质中使用光壁球囊霉的接种处理改善了幼苗生长。
在温室条件下，印楝副产品有利于该植物幼苗的生长。接种光壁球囊霉主要在含有印楝叶残渣的基质中促进植物生长，为在苗圃条件下生产该作物的幼苗提供了一种替代方法，这可以减少对环境有影响的化学肥料的需求。
