Higher gross margin of tobacco in Mexico resulted from treatments of Specialty Plant Nutrition

From November 2010 through May 2011, a field test was carried out on Burley tobacco in Santiago de Ixcuintla (Nayarit State, Mexico). On a tobacco plantation belonging to grower Juan Gonzalez Rangel, associate of the tobacco company Tabacos del Pacífico Norte in Santiago de Ixcuintla, the effects of treatments with granular fertilisers were compared against treatments with water-soluble Specialty Plant Nutrition (SPN) products. The purpose of this test was to assess the effect of each treatment on the yield and the quality of the leaves. Each treatment was carried out on a plot of 1 hectare. The details can be observed in Tables 1 and 2.

The results clearly showed a positive effect of SQM's watersoluble Specialty Plant Nutrition (SPN) products on overall yield, the total number of leaf strings, leaf size, the number of leaves, and plant height (Figure 3). The total yield and the yield per leaf quality also increased (Figure 4), as well as the total gross revenue and the gross revenue per leaf quality (Figure 5).

Entre otros beneficios, el tratamiento SQM resultó en hojas de tabaco más largas y de mejor calidad.
