Abstract

Objective: a profitability comparison was made between corn production with the use of a variable doser and a conventional fertilizer doser. The variable doser for the differentiated application of fertilizer was built at CENEMA of INIFAP. An experimental plot was established, applying the recommendations established in the technological package for grain corn production, by INIFAP, in the State of Mexico.With the variable doser, it was verified that the fertilizer needs of the soil required 11.5 % less than that supplied by a constant application doser. The yield obtained was 5.6 % higher than in the conventional one. The B/C benefit/cost ratio of corn production with the variable doser was 1.60, while with the conventional doser it was 1.44, for both cases the profitability is positive, with a difference of $0.16 cents. The profitability with the use of the variable doser was higher than with the conventional doser.
使用可变配料系统对玉米作物进行差异化施肥的盈利能力分析
目标:对使用可变施肥器和传统施肥器生产玉米的收益进行比较。在墨西哥州,根据 INIFAP 谷物玉米生产技术包中的建议,建立了一块试验田,使用变量施肥器,土壤对肥料的需求比恒定施肥器少 11.5%。获得的产量比传统方法高出 5.6%。使用可变施肥器生产玉米的 B/C 效益/成本比为 1.60,而使用传统施肥器的 B/C 效益/成本比为 1.44,两种情况下的利润率均为正值,差值为 0.16 美分。
