Dear Sir
Soil
Tuberose can be grown in wide range of soils, even those affected by salinity and alkalinity conditions. However, loam and sandy soils, having a pH of 6.5 to 7.5 with good aeration and drainage are considered ideal for its successful cultivation.
Climate
Tuberose is a tropical plant and grows well round the year under moderate climatic conditions like in Bangalore. However, it is well adapted to our sub-tropical conditions (north Indian plains) and grows profusely from April to November. It becomes dormant with the advent of winter season, as evident by the cessation of vegetative growth. High (40 degree centigrade) as well 10 degree centigrade temperature reduce the length of spike, weight and quality of flowers.
Nutrition
The nutritional requirement for tuberose crop varies with several factors like climatic conditions, types of soil, cultivar planted and spacing followed. It was found that nitrogen is much more vital element than phosphorus or potassium which influences yield and quality of flowers and bulb production in tuberose.
Water Management It is advisable to irrigate the field before planting of bulbs and thereafter further irrigation could be avoided until the bulbs sprouts. Too much moisture at the time of sprouting will result in rotting of bulbs and same conditions during flowering period will adversely affect the development of spikes and florets.
