Flowering and rhizomes qualities of Curcuma hybrid (C. petiolata Wall, × C. aurantiaca van Zijp) affected by NPK
Effect of NPK levels in nutrient solution were studied in Curcuma hybrid (C. petiolata Wall. × C. aurantiaca Van Zijp) growing in substrate culture. The media consisted of sand and rice-husk charcoal at the ratio 1:1 (v/v). Three levels of nitrogen (100, 200 and 300 mg N L-1) combined with two level...

Three levels of nitrogen (100, 200 and 300 mg N L-1) combined with two levels of phosphorus (50 and 100 mg P L-1) and two levels of potassium (200 and 300 mg K L-1) were supplied to plants twice a week from planting to flowering (18 wk after planting) and changed the rate to once a week from flowering until one month before harvest (22 wk after planting).
