EFFECT OF N, P, K CONCENTRATIONS ON YIELD AND FRUIT QUALITY OF TOMATO (SOLANUM LYCOPERSICUM L.) IN TUFF CULTURE

This study concluded that high concentration of N, P and K in the nutrient solution gave higher total yield and tomato fruit weight than the control nutrient solution in tuff culture grown tomato. High phosphorus concentration (100 ppm) in the nutrient solution gave the highest total and marketable yield, number of marketable fruits and yield per plant, while low phosphorus concentration (20 ppm) gave the highest total soluble solids and titratable acids content in tuff culture grown tomato. The control nutrient solution gave the least total soluble solids, titratable acidity content and the highest pH of tomato juice.
