| Abstract:
This study has been carried out to investigate the salinity and the nutritional problems induced by salinity for greenhouse cucumbers in the East Marmara Region. Soil, irrigation water, leaf and fruit samples were collected from 26 greenhouses and necessary information about the yield, fertilizing, irrigation techniques and greenhouse conditions thus obtained for two years (1996-1997). According to the results of soil analysis, there seemed to have problems of salinity, approximately in 43-50%, high soil pH, in 60%, and low organic matter content, in 75%, high Na, CI and HCO3, 35-44%, 45-51% and 51-65% respectively in both years, of the units studied. The irrigation water was generally good and in very good quality for the salinity in 40% of units. The sodium and chloride contents of the water were above the standards in 30% and 25% respectively. Nitrogen, phosphorus and potassium contents of the leaves collected were found to be at sufficient levels, but boron and calcium contents were deficient in nearly all and iron in 40%, manganese in 60%, zinc in 30%, magnesium in 45% (only in the second year) deficient in the greenhouses surveyed. Na and Cl contents of the leaves were at high levels in the 41% and 26% of the units, respectively. | |
