Abstract
The present investigation was carried out to study the effect of different levels of nitrogen and spacing on the quality characters and nutrient uptake in roselle. A field trial was conducted in a Factorial Randomized Block Design with five levels of nitrogen (50, 100, 150, 200 and 250 kg ha -1 ) and three levels of row spacing (60, 90 and 120 cm). The results of the present study revealed that the spacing of 120 × 75 cm and nitrogen application of 250 kg ha -1 was found to be superior in improving the quality characters like titrable acidity, pectin, ascorbic acid, anthocyanin content, plant nitrogen, phosphorus and potassium content.
