Abstract

Planting dates (PDs) are well established for a wide range of agronomic crops to maximize yield and quality, but this guidance is lacking for industrial hemp (Cannabis sativa L.) produced for fiber, especially in the Mid-Atlantic region. With fiber hemp cultivation commencing with the passing of the 2014 and 2018 US Farm Bills, it is imperative to understand how this crop can fit into established crop rotations. Therefore, the objective of this research was to determine optimum planting and harvest dates for fiber hemp in the Mid-Atlantic to optimize plant characteristics. We hypothesized that earlier planting and harvest would increase fiber hemp yield and quality. The 2-year study was performed in two locations in Maryland (three total site-years) and utilized a split plot, randomized complete block design with PD as main plots and either variety or harvest date as split plots. The results indicated that to maximize fiber hemp yield and associated desirable plant traits, hemp must maximize light interception throughout the entire summer growing season; therefore, shortened-season fiber hemp is not likely to maximize productivity. These results are promising for the incorporation of fiber hemp into current crop rotations in Maryland and the greater Mid-Atlantic region. Data supported that lignin was the only fiber quality parameter affected by PD, with earlier plantings having increased content. This information allows farmers to make informed decisions about the impacts of PD and the desired end product. The flexibility around optimal PD of fiber hemp allows farmers to prioritize planting of summer cash crops, such as corn and soybean, ahead of fiber hemp while minimizing concerns of negatively impacting fiber hemp yield.

早期建立增加产量和纤维质量的工业大麻(大麻sativa L.)生产在大西洋中部
为了最大限度地提高产量和质量,许多农艺作物都制定了种植日期(pd),但对于用于纤维生产的工业大麻(大麻sativa L.),特别是在中大西洋地区,缺乏这一指导。随着2014年和2018年美国农业法案的通过,纤维大麻的种植开始了,了解这种作物如何适应现有的作物轮作是势在必行的。因此,本研究的目的是确定大西洋中部纤维大麻的最佳种植和收获日期,以优化植物特性。我们假设早期种植和收获会增加纤维大麻的产量和质量。这项为期2年的研究在马里兰州的两个地点进行(总共3个站点年),采用分割区,随机完全区设计,PD为主区,品种或收获日期为分割区。结果表明,为了最大限度地提高纤维大麻产量和相关的理想植物性状,大麻必须在整个夏季生长季节最大限度地提高光截获;因此,短季纤维大麻不可能最大限度地提高生产率。这些结果有望将麻纤维纳入马里兰州和大西洋中部地区目前的作物轮作中。结果表明,木质素是唯一受PD影响的纤维品质参数,早期种植木质素含量增加。这些信息使农民能够对PD的影响和期望的最终产品做出明智的决定。围绕麻纤维最佳PD的灵活性使农民能够优先种植夏季经济作物,如玉米和大豆,而不是麻纤维,同时最大限度地减少对麻纤维产量的负面影响。
