Growth, Development and Yield of Kenaf as Affected by Planting Dates and N Fertilization

Kenaf (Hibiscus cannabinus l) consists of various beneficial components like stalks, seeds, leaves, fibers, oils, proteins, allelopathic chemicals, and fiber strands, among other things. Despite the numerous uses of the crop, there is little or no information on optimum agronomic practices such as planting date and N fertilization of the crop in the Upper East Region (UER) of Ghana where the crop is widely cultivated by smallholder farmers. Field experiments were therefore carried out in 2020 and repeated during the 2021 cropping season in the study area. The objective of the study was to determine appropriate planting date and N fertilization for increased kenaf productivity. In each year, the treatments consisted of 3 × 5 factorial combinations of three planting dates (1st July, 7th July and 14th July) and five levels of N (0, 20, 40, 60 and 80 kg/ha) replicated three times. The design of the experiment was a split-plot with the N fertilizer as the main plot and the planting date assigned to sub plot. The results showed that, planting kenaf in early (1st) July or N fertilization at the rate of 60 kg/ha increased plant density, stem height, stem diameter, dry bast and core yields in both cropping seasons.

在一根天然气制甲醇蒸汽转化炉管内壁某位置发现瘤状物,不仅突出于内壁还向炉管内部生长,导致炉管性能受到严重影响。针对此罕见现象,文章采用光学显微镜,扫描电子显微镜和能谱仪等手段对该瘤状物的组织和成分进行观察分析。结果表明:瘤状物的本质为Cr与Fe的氧化物,与基体之间存在不同于常规氧化物的过渡区,且在瘤状物内部观察到许多富碳的疏松结构。推测瘤状物的形成机制与还原-氧化相互共同作用有关。
