Salinity Effect of Nutrient Solution on Maradol papaya

Papaya (Carica papaya L.) is a crop of great economic importance. It the fourth most produced tropical fruit in world. The substantial problems faced during its production are pests and diseases, which why it has been planted under greenhouse conditions. However, required that plants not be height to need tall greenhouses. Therefore, this research aims evaluate salinity effect identify nutritive solutions reduce plant height. experimental design was completely randomized with four treatments ten replications. were concentrations Steiner nutrient solution (50 %, 100 150 200 %) whose composition anions (phosphate, nitrate, sulfate) cations (potassium, calcium, magnesium), thus generating electrical conductivity 1.0, 2.0, 3.0, 4.0 dS/m, respectively. variables evaluated height, number leaves, stem diameter, foliar area, chlorophyll b concentration, proline content, concentration. nutrients comprise nitrogen, phosphorus, potassium, magnesium. analysis variance indicated significant differences all except magnesium As increased, leaf calcium decreased, but nitrogen increased. We conclude dS/m (200 can grow
