چکیده
|
'petra' croton (codiaeum variegatum blume) was grown in peatmoss-perlite (pp), singly or with zeolitic tuff (ppz). when the substrates reached 80% of available water, the plants were irrigated with tap water or wastewater alone or containing (ppm) 100n-44p-83k or 200n-88p-166k. the results indicate that zeolite increased plant width, fertilization increased node and leaf number and wastewater supplemented with 200n-88p-166k increased shoot weight. tissue n was maximal for pp receiving wastewater or 200n-88p-166k and for both substrates receiving 100n-44p-83k through wastewater or 200n-88p-166k through tap water. tissue p was maximal for 200n-88p-166k applied through wastewater to pp or through tap water to ppz. addition of 100n-44p-83k through wastewater or 200n-88p-166k through either water quality to pp resulted in the highest tissue k. substrate ph decreased to 4.5 in pp receiving 200n-88p-166k, but increased to 8.3 in non-fertilized ppz. values of ec, n, p and cl were maximal in pp receiving wastewater and minimal in ppz. electrical conductivity, n and p were the highest in pp receiving 200n-88p- 166k and lowest in non-fertilized ppz, whereas k was the highest in ppz receiving 200n-88p-166k and lowest in non-fertilized pp. the substrate ppz had higher k and na than pp. wastewater increased k in pp and na in both substrates
