摘要

该研究比较了农场机械化和农民的田间实践,以证明机械化玉米种植的农艺和经济可行性。试验采用完全随机区组设计,采用机械化栽培和农民栽培2个处理,3个重复,选用10v10杂交品种。农艺学方面,农民耕作的种子率和尿素施用量(分别为17.05 kg ha-1和186.41 kg ha-1)低于机械化耕作(分别为30.00 kg ha-1和348.00 kg ha-1)。因此,农民做法的产量(7.56 t ha-1)低于机械化做法(10.43 t ha-1),这是由于农民做法的植物数量较少,不育性较高,穗轴直径较小。机械化生产的效益成本比(3.76)高于农民生产的效益成本比(2.44)。劳动力短缺可以通过定制招聘中心通过机械化来缓解,即使在小农户玉米种植者中也是如此。

Appraisal of Farm Mechanization and Farmer’s Field Practice of Maize Farming at Lamahi Municipality, Dang, Nepal
The study compares farm mechanization and farmer’s field practice to document the agronomic and economic feasibility of mechanized maize farming. The research was carried out in randomized complete block design with 2 treatments of mechanized practice and farmers practice and 3 replications as location for the winter maize using 10v10 hybrid variety. In agronomic aspect, seed rate and urea application in farmers practice (17.05 kg ha-1 and 186.41 kg ha-1 respectively) were found lower to mechanized practice (30.00 kg ha-1 and 348.00 kg ha-1 respectively). Consequently, lower yield was found in farmers practice (7.56 t ha-1) to mechanized practice (10.43 t ha-1) which was attributed by lower plant population, higher sterility, and smaller cob diameter in farmers’ practice. The benefit cost ratio was higher in mechanized practice (3.76) to farmer’s practice (2.44). Labour shortage can be mitigated by mechanization through the custom hiring center even in small holder maize growers.
