Análisis del rendimiento de la fresa (Fragaria chiloensis L. Duch) sometida a diferentes tipos de sustratos dentro de un cultivo semi-hidropónico en la parroquia Salinas provincia del Imbabura

This research studied the agronomic performance of the strawberry crop to the application of five types of substrates in semi-hydroponic area Salina Region Ibarra, Imbabura, located in the following geographic coordinates: latitude 00 º 29 '36.67'' and longitude 78 º 07' 53.25 "and a height of 1387 meters. The objective was to evaluate the agronomic performance in the development and production of strawberry under different types of substrates in semi-hydroponic cultivation, identify the substrate with better response in the cultivation of strawberries and analyzing economic treatments. Design We used randomized complete block (RCBD) with five treatments and three repetitions. The total experimental area had 166 m2, each plot was 2.3 m2 and 0.8 m2 useful area of the separation between replicates and plots was 0.5 m. Variables were evaluated: plant height at 30, 60 and 90 days after transplantation, days to flowering, percentage of viable plants, fruit size, fruit weight, fruit number and yield. All variables were subjected to analysis of variance and to determine the statistical difference between treatment means, was handled Tukey test at 5% level. According to the experimental results determined the following: That the media that presented the best agronomic performance in both development and production of strawberry was Sand + Peat + cane bagasse as a soil amendment. With the substrate Sand + Peat + cane bagasse was more economic use of $ 45,626.92 and a 2.68 ratio of cost / benefit beyond the control treatment that amounted to $ 2,096.73 USD ratio equivalent to 0.20 cost / benefit. The substrate Pomina + Peat+ Humus Peat recorded a negative value compared against the witness.
