本研究旨在研究杨树种植的经济学以及杨树种植者面临的限制。研究了三种类型的农林业系统（AFS）； AFS-I（小麦草饲料）、AFS-II（前三年为甘蔗，然后连续几年为小麦草饲料）和 AFS-III（第一年为马铃薯草饲料，然后连续几年为小麦草饲料）。最高净现值 (NPV) 为卢比。卢迪亚纳的 AFS-II 第 6 年每英亩 116068.60 卢比，而当时的价格为卢比。 Ropar 第 6 年 AFS-II 每英亩 126891.90 美元。在两个地区中，第 6 年 AFS-II 的年金值 (AV) 也是最高的。 AFS-II 的内部回报率 (IRR) 在两个地区最高，即卢迪亚纳地区为 53.82%，罗帕尔地区为 51.72%。效益成本比 (BCR) 在第 6 年最高，即卢迪亚纳的 AFS-II 为 4.79，罗帕尔地区的 AFS-II 为 5.43。生产中最突出的问题是杨树块植混交问题和技术缺乏。与杨树营销相关的主要问题是林产品市场不受监管和价格波动。结论是杨树种植是一项有利可图的事业。然而，他们的盈利能力可以通过政府进一步提高。杨树人工林的干预和加强管理。
The present study was undertaken to study the economics of Poplar cultivation and constraints being faced by the Poplar growers. Three types of Agroforestry systems (AFS) were studied; AFS-I (Wheat-kharif fodder), AFS-II (Sugarcane for first three years and then Wheat-kharif fodder for the successive years) and AFS-III (Potato- kharif fodder for first year and then Wheat- kharif fodder for the successive years). The highest net present value (NPV) was Rs. 116068.60 per acre in Ludhiana for AFS-II in 6th year while it was Rs. 126891.90 per acre for AFS-II in 6th year in Ropar. Annuity value (AV) was also highest for AFS-II in 6th year in both Districts. Internal rate of return (IRR) was highest for AFS-II in both the districts i.e. 53.82 per cent in Ludhiana and 51.72 per cent in Ropar District. Benefits cost ratio (BCR) was highest in 6th year i.e. 4.79 for AFS-II in Ludhiana and 5.43 for AFS-II in Ropar Districts. The most prominent production problems were the problem of interculture in block plantation of Poplar and lack of technical know-how. The major problems related to marketing of Poplars were unregulated markets of forest products and price fluctuations. It was concluded that the Poplar cultivation was a remunerative venture. However, their profitability could be further enhanced through Govt. intervention and enhanced management of Poplar plantation.
