The role of organic fertilization and arbuscular mycorhizal fungi inoculation on sweet corn growth on rasau series soil | IJAAR

The objective of this research was to determine the effect of organic and bio fertilization on the growth performance of corn planted on Rasau series soil. A factorial experiment of 5 x 2 Randomised Complete Block Design replicated 4 times was conducted at the glasshouse of Universiti Malaysia Terengganu. The factors include organic manure at 5 levels OM1 (control), OM2 (chicken manure), OM3 (cattle manure), OM4 (horse manure) and OM5 (biochar), and arbuscular mycorrhizal Fungi at 2 levels M1 (with) and M2 (without), the variables measured were plant height, stem girth, leaf height, leaf number, leaf length, leaf width and leaf area at 2, 4, 6 and 8 weeks after planting (WAP). The data collected were analyzed using Analysis of Variance (ANOVA) with Statistical Analysis System (SAS) and means separated using Duncan’s Multiple Range Test at p<0.05. The growth performance of the test crop (sweet corn) in this experiment was significant in the measured parameters with chicken manure (OM2) under mycorrhizal inoculation (M1). The result of this study showed chicken manure when inoculated with AMF can boost sweet corn production on Rasau series soil

本研究旨在探究有机肥料与生物肥料对拉绍（Rasau）系列土壤种植玉米生长性能的影响。本试验采用5×2因子随机完全区组设计，于马来西亚登嘉楼大学温室开展，共设置4次重复。试验因子包含2个维度：其一为5个水平的有机肥处理，分别为OM1（对照组）、OM2（鸡粪）、OM3（牛粪）、OM4（马粪）与OM5（生物炭）；其二为2个水平的丛枝菌根真菌（arbuscular mycorrhizal Fungi, AMF）处理，分别为M1（接种）与M2（不接种）。分别于种植后2、4、6、8周（Weeks After Planting, 简称WAP）测定株高、茎粗、叶高、叶数、叶长、叶宽及叶面积。采用统计分析系统（Statistical Analysis System, SAS）对采集的数据进行方差分析（Analysis of Variance, ANOVA），并以邓肯多重比较法对各组均值进行多重比较，显著性水平设定为p<0.05。本试验供试作物（甜玉米）的各项生长性能指标均存在显著差异，其中接种丛枝菌根真菌的鸡粪处理（OM2+M1）效果最优。本研究结果表明，在拉绍系列土壤上，鸡粪配施丛枝菌根真菌可提升甜玉米的生产性能。
