Biomass for energetic use can be procured from various sources including willow short rotation crops (WSRC). The feasibility of willow crops, however, is dependent on the costs incurred by operations such as the plantation, maintenance, harvesting and transport. In small scale applications, cost balancing often results in the use of equipment designed for general agricultural purposes to carry on the operational management of WSRC. This study evaluated the productive performance in planting operations of WSRC for a planting equipment consisting of regular farming tractors used to propel machines designed to support planting on single twin rows. Planting equipment consisting of 4 different types of farming tractors fitted with willow planting equipment was tested in 14 filed plots to be able to compute the main performance indicators such as the net and gross productivity rates. An evident variability in terms of time consumption on categories was observed at plot-level, and the planting time was related to a great extent to the operated area. The size of areas subjected to planting operations was the most important factor that affected productive performance. Variation of net productivity rate was explained largely by the ratio of the length of headland returning maneuvers to total length covered in a given plot. The model developed for the total study time shows that, in the observed conditions, it may take more than 7 h to plant one hectare. The equipment taken into study stands for a flexible option for small-scale farmers which could increase the utilization rates of their farming tractors by using them in other agricultural operations when needed. In addition, the studied equipment fits well to very narrow and small-sized plots, as such situation is typical to Romania and other European countries.

可以从包括柳树短轮作（WSRC）在内的各种资源中获得用于能源的生物质。然而，柳树作物的可行性取决于诸如种植，维护，收割和运输等业务所产生的成本。在小规模应用中，成本平衡通常会导致使用为一般农业目的而设计的设备来进行WSRC的运营管理。这项研究评估了WSRC的种植设备的生产性能，该设备由常规农用拖拉机组成，用于推动旨在支持单双行种植的机器。在14个样地中对由4种不同类型的配有柳树种植设备的农用拖拉机组成的种植设备进行了测试，以能够计算出主要性能指标，例如净生产率和总生产率。在样地水平上，类别上的时间消耗方面存在明显的差异，并且播种时间在很大程度上与作业区域有关。种植作业的面积是影响生产性能的最重要因素。净生产率的变化很大程度上是由岬角返回机动的长度与给定地块覆盖的总长度之比来解释的。为总研究时间开发的模型显示，在观察到的条件下，种植一公顷土地可能需要7个小时以上。研究中使用的设备代表了小型农民的一种灵活选择，可以通过在需要时将其用于其他农业活动来提高其农用拖拉机的利用率。此外，所研究的设备非常适合非常狭窄和小规模的地块，因为这种情况对于罗马尼亚和其他欧洲国家来说是典型的。
