Abstract

Objective: To evaluate the performance of a controlled release fertilizer on the vegetative and productive development of coffee trees in production. Theoretical framework: The use of slow, controlled release fertilizers or smart fertilizers can allow the reduction of fertilization operations, in addition to being characterized by the availability of nutrients to plants at the correct time, with the consequent reduction in maintenance expenses, labor of work and fuel. Method: A trial was conducted in Alto Paranaíba, Minas Gerais, during 4 harvests, to evaluate the performance of a slow-release fertilizer on the vegetative and productive development of coffee trees in production, as well as the impacts of this technology on the scaling of mechanized operations in property. Results and conclusion: With the use of slow-release fertilizers, it was concluded that: slow-release potassium nutrition reduces the competitive effect of potassium with Calcium and Magnesium; productivity gains are obtained when compared to the use of conventional fertilizers; there is an increase in coffee yield; at a rate of 80% of the dose, there are advantages in the nutrition of the coffee plant, especially in old crops; There is a reduction in the number of machine hours worked in the agricultural year with a consequent reduction in production costs, making it possible to redistribute mechanized operations, reducing labor and the volume of operations in the months that demand the most services. Implications of the research: With the results of the research, over two biennia, it was possible to identify the positive factors of using slow-release fertilizers for coffee trees, both in biometric and productive aspects and in the optimization of mechanized operations in a coffee farm cultivated in the cerrado miner. Originality/value: a better understanding of the effects of using slow-release fertilizer technology to increase productivity and better economic and environmental performance in coffee agribusiness.

控释肥料在咖啡作物生产中的技术经济可行性
目的:评价控释肥料对生产中咖啡树营养和生产发育的影响。 & # x0D;理论框架:使用缓慢、控释肥料或智能肥料可以减少施肥操作,除了其特点是在正确的时间向植物提供养分,从而减少维护费用、劳动和燃料。 & # x0D;方法:在米纳斯吉拉斯州Alto Paranaíba进行了一项试验,在4次收获期间,评估缓释型肥料对咖啡树营养和生产发育的影响,以及该技术对农场机械化操作规模的影响。 & # x0D;结果与结论:在施用缓释肥料的情况下,缓释钾营养降低了钾与钙、镁的竞争效应;与使用传统肥料相比,获得了生产力的提高;咖啡产量增加了;在80%的剂量率下,对咖啡树的营养有好处,特别是对老作物;农业年的机器工作时数减少,生产成本随之降低,使重新分配机械化作业成为可能,在需要最多服务的月份减少劳动力和业务量。& # x0D;研究的意义:根据两年多来的研究结果,可以确定在塞拉多矿种植的咖啡农场使用缓释放肥料的积极因素,包括生物特征和生产方面,以及优化机械化操作。& # x0D;原创性/价值:更好地理解使用缓释肥料技术在咖啡农业综合企业中提高生产力和更好的经济和环境绩效的影响。
