La relación Mn/Zn en la producción de manzana de calidad c.v. Golden delicious Golden, en suelos calcáreos

Abstract

The present work was realized in the state of Arteaga, Coahuila, Mexico, during the agriculture cycle of the year 1998. there they use applications of micronutrients of zinc and manganese, with doses of 0, 20,40, 80 ppm of zinc and 0, 60, 90, 120, ppm of manganese; and as a result there were 16 treatments with 3 repetitions. The longitudinal growth of the branches show a haughty difference between treatments in the four cardinal points. The diameter of the branches shown a difference between the treatments in the cardinal points of south and east and in the north and south point there wasn’t any difference. For the growing of the fruit in its polar diameter of the cardinal point of south, there we obtained a difference between treatments, but we can say the same thing for the east point. The growing of fruit in the equatorial diameter of the south side, we obtained a difference between treatments and for the east there wasn’t any difference. The brix grades shown a difference in the application of micronutrients. The performance was classified in categories; because, the second and third category didn´d show an statistics difference; the extra categories, the first and total performance did how a different respond in the application of micronutrients. For the micronutrients zinc and manganese in the plant, both of them are in the rank of enough, says Benton and Harry, 1991. Both micronutrients hare influence in the vegetation growth as in fruit, there are it also affects the performance, the brix grades and the concentration of this in the apple plant.
