COIR EMPLOYED AS SOILLESS CULTIVATION SUBSTRATE AND ITS INTERFERENCE WITH NUTRIENT SOLUTION DURING TWO TOMATOES CROPPING PERIODES (CASE STUDY)
Keywords:
soilless cultivation, nutrient solution, coir substrate, tomatoAbstract
The experiment was conducted in the glasshouse of TEI of Thessalia, for two growing periods, in soilless tomato cultivation, with coir substrate (open system). The electrical conductivity of the inflow solution to crops, fluctuated from 1.80 to 2.55 dS m-1 and pH values ranged from 5.5 to 6.8, while for the efflux solution from the crops, ranged from 2.00 to 3.50 dS m-1 for electrical conductivity, and from 5.5 to 6.9 for pH. On the coir substrate, the electrical conductivity ranged from 0.3 to 1.13 dS m-1 (water extract of 1 part of coir: 5 parts of H2O) and for pH from 5.87 to 6.83 during the first crop period; during the second cultivation, the electrical conductivity it fluctuated from 0.65 to 1.91 dS m-1 and for pH from 5.7 to 6.7. According to this study, 20% of substrate was decomposed, CEC increased, also the salinity status of the coir increased essentially during the second cultivation period, correlated with nitrate and phosphate forms enrichment of the substrate, while a slight negative affection to the crop production was observed; in generally, the coir substrate, is a good choice with excellent results for cultivation return.
