Analysis of the profitability of the use of a variable dispenser for the differentiated application of fertilizer in corn cultivation

Abstract

Objective: Carry out a profitability comparison between corn production with the use of the variable dispenser for application and a conventional fertilizer dispenser.

Design/methodology/approach: The profitability of a variable dispenser for the differentiated application of fertilizer was evaluated, which has a sensor that measures the requirements of the soil, designed and built at the National Center for Standardization of Agricultural Machinery, with respect to a conventional dispenser. For this, a corn crop was established in an experimental plot, applying the recommendations established in the technological package for the production of grain corn, by INIFAP, in the State of Mexico.

Results: With the variable dispenser, it was verified that the soil needs require 11.5% less fertilizer than that supplied by a constant application dispenser. The yield obtained was 5.6% higher than in the conventional one. The B/C benefit/cost ratio with the variable dispenser was 1.60, with the conventional dispenser it was 1.44, for both cases the profitability is positive, with a difference of $0.12 cents. The variable dispenser, being manufactured with national products, makes it easier for the producer to acquire and change spare parts, as well as its use and maintenance.

Limitations on study/implications: The experiment was carried out and tested on the land of the Valle de México Experimental Field this year; it is important to carry on other years.

Findings/conclusions: The profitability with the use of the variable dispenser was positive, this represents an alternative for the acquisition of implements with easy availability, use and maintenance for producers.
