Evaluación de tres soluciones nutritivas en el cultivo de apio apium graveolens mediante el método de raíz flotante en invernadero

The present qualified investigation evaluation of three nourishing solutions in the culture of celery (Apium graveolens) by means of the method of floating root in greenhouse I her carry out in the Faculty of Agricultural Sciences of Machala's Technical University placed to 5,5Km of the route Machala - Passage, parish The Change, canton Machala, province The Gold - Ecuador, the aims were: 1. To prove three nourishing solutions in the culture of celery (Apium graveolens) and to establish the best solution in the system of floating root in greenhouse; 2. To establish that treatment presents better agronomic characteristics; 3. To obtain the cost of production for the treatments.The area of test was of 32m2 under greenhouse the technical of floating root consists in that the roots are immersed in the nourishing solution and the air part this one supported on an inert way that floats, him the subsecretary I become oxygenated to all the treatments with a compressor that was driven automatically by a timer. Three nourishing solutions were proved by an initial concentration T1, fewer 25 % that was T2 and mas 25 % that was T3 proved opposite to or witness to base NPK. The statistical design that I use was the completely random one with three more treatments a witness and ten repetitions.Of the nourishing calculated solutions the best was the treatment T1 that by means of the economic analysis he presented a clear usefulness of $.672,97/10m2 correspondent to a relation B/C of 1,28 and one profitability of 127,69 %, which turns out to be profitable from 2 years.
