This study sought to determine whether the technology acceptance model (TAM) could adequately explain the adoption and use of biological inputs (BI). A sample of 150 cereal farmers from Bilehsavar County of Ardabil Province, Iran, participated in this study for data collection. Two key components of TAM, i.e., perceived usefulness (PU) and perceived ease of use (PEOU), along with attitudes, intentions and usage behavior, were measured using five-point Likert-type scales and modeled using structural equation modeling (SEM). Generally, scores on all scales indicated that behavioral intention was not well known and used by farmers. Intention to use and usage behavior indicated the lowest mean scores, implying that few farmers intended to use or were using BI. PEOU showed the lowest mean score suggesting respondents perceived that BI was not easy to use. Attitude and PU scores indicated that most of the respondents had fairly negative to neutral attitudes and perceptions toward the usefulness of BI. Attitudes and intentions accounted for 52% of the variance in farmers’ behavior. Attitude and PU, in turn, accounted for 56% of variability in intentions. PU and PEOU also accounted for 64% of the variability in attitudes. Based on these findings, an extension education program to facilitate the application of BI will improve PEOU and promote farmers’ PU and intentions. Visits to demonstration farms and discussion sessions are useful to improve farmers’ attitudes and thereby to promote their intention to adopt useful technologies. Removing agrochemicals’ subsidies, providing farmers with incentives for reducing agrochemicals and increasing BI use are essential to encourage farmers in the adoption and application of BI.

谷农生物投入的使用：技术接受模型的应用

本研究试图确定技术接受模型 (TAM) 是否可以充分解释生物投入 (BI) 的采用和使用。来自伊朗阿尔达比勒省 Bilehsavar 县的 150 名谷物农民的样本参与了这项数据收集研究。TAM 的两个关键组成部分，即感知有用性 (PU) 和感知易用性 (PEOU)，以及态度、意图和使用行为，使用五点李克特型量表进行测量，并使用结构方程模型 (SEM) 进行建模. 一般而言，所有量表的分数都表明行为意图未被农民所熟知和使用。使用意图和使用行为的平均得分最低，这意味着很少有农民打算使用或正在使用 BI。PEOU 的平均分最低，表明受访者认为 BI 不容易使用。态度和 PU 分数表明，大多数受访者对 BI 的有用性持相当消极或中立的态度和看法。态度和意图占农民行为方差的 52%。反过来，态度和 PU 占意图变异性的 56%。PU 和 PEOU 也占态度变异的 64%。基于这些发现，促进 BI 应用的推广教育计划将改善 PEOU 并促进农民的 PU 和意图。参观示范农场和讨论会有助于改善农民的态度，从而促进他们采用有用技术的意愿。取消农化补贴，
