Abstract
The implementation of the technology of efficient microorganisms in the agricultural activity bears to multiple benefits. The objective was to evaluate the influence of the IHPLUS biofertilizer application in the development of coffee postures and the control of diseases with plugs technology. It was developed in a nursery of the Estación Experimental Agro-Forestal of Jibacoa during the nursery years 2015-2016 and 2016-2017 with plugs of 180 cm3. Two treatments were evaluated: postures of coffee sprayed with IHPLUS to 2 % from the phosphorus phase and postures sprayed with water. To the seedlings were evaluated the affectations of the rottenness of the root and when the postures obtained the sixth couple of leaves they were determined the height, the diameter of the shaft, the total dry mass, the foliate area, the infestation and of distribution index of iron stain. The treatments were distributed in a design of randomized blocks. The halves were compared by means of the test T for independent samples. The application of the IHPLUS reduced the losses of postures caused by the rottenness of the root in 77,08 %. When IHPLUS was sprayed diminished the infestation index of the iron stain until 21,43 % and that of distribution index until 24%. With the use of the IHPLUS increments were obtained in 16,2 %; 20 %; 32,3 % and 22,5 % in the height, the diameter of the shaft, the total dry mass and the foliate area respectively of the coffee postures, with the employment of the plugs technology of 180 cm3.
