Adlay is an edible high nutritious minor cereal. The research aimed to study the adlay performance when cultivated intercropped on young teak ( L.f.) plantation. The treatments were consisted of two factors that were arranged by factorial (3 × 3) in randomised completed block design with four replicates. The first factor was three fertilisation dosages of NPK (16-16-16), as 0 g/hole (F0), 2 g/hole (F2) and 4 g/hole (F4). The second factors were three planting space as 2 m × 2 m (PS2), 3 m × 3 m (PS3) and 4 m × 4 m (PS4). The parameter observed were vegetative growth which was consisted of plant height, the number of leaves, tillers and sub tillers, leaf chlorophyll content, grain production and biomass weight. The results revealed that fertilisation treatment were significantly affected the growth and production of adlay. On 12 weeks after planting, the F4 treatment produced the tallest plant, and the highest leaf number. The highest grain number/plant was achieved on the F2 treatment that was significantly different compared with the control (F0). The shading intensity due to the teak coverage significantly affected adlay growth and production. The PS4 treatment produced the highest number of leaves, tillers and grains. The combination of F2 and PS4 treatments resulted in the best growth and production. The PS2 treatment which has lower light intercepted by plants due to lower incident light intensity, resulting in a significant reduction in plant growth and production. It is suggested that adlay offers potency as a component of agro-forestry on the teak plantations.
薏仁是一种可食用的高营养小谷物。本研究旨在探讨薏仁与柚木(柚木属)幼林间作时的生长表现。试验处理由两个因素组成,采用析因试验(3×3),随机完全区组设计,重复4次。第一个因素是三种NPK(16 - 16 - 16)施肥量,分别为0克/穴(F0)、2克/穴(F2)和4克/穴(F4)。第二个因素是三种种植间距,分别为2米×2米(PS2)、3米×3米(PS3)和4米×4米(PS4)。观测的参数包括营养生长,如株高、叶片数、分蘖数和次分蘖数、叶片叶绿素含量、籽粒产量和生物量重量。结果表明,施肥处理对薏仁的生长和产量有显著影响。种植后12周,F4处理的植株最高,叶片数最多。F2处理的单株籽粒数最高,与对照(F0)相比差异显著。柚木覆盖造成的遮荫强度显著影响薏仁的生长和产量。PS4处理的叶片数、分蘖数和籽粒数最多。F2和PS4处理的组合导致最佳的生长和产量。PS2处理由于入射光强度较低,植株截获的光较少,导致植株生长和产量显著降低。建议薏仁作为柚木种植园农林复合经营的一个组成部分具有潜力。
