Description Ginger (Zingiber officinale Roscoe) belongs to family Zingiberaceae is an important spice, native to south or south East Asia. It is one of the earliest oriental spices known to Europe. More than 25 countries cultivate this crop in tropical and subtropical regions of the world. Information on ginger phenology and degree day requirement is not available that would be useful to schedule cultural operations. Experiment was conducted at Indian Institute of Spices Research, Experimental Farm, Peruvannamuzhi, Calicut District, Kerala State, India (geographical coordinates 11 °.342 N,75°.482 E and 60 m MSL) during 2007-08 crop season. Improved varieties of ginger - Varada, Rejatha, Mahima,
Moran and Himachal planted on 30th April, 15th May,30th May and 15th June. Experiment was laid out in a split-plot design (varieties in main plot and time of planting in Sub-plot) with three replications and harvesting was done on 29 January. The observations on emergence of new sprout and first and last sucker, leaves and sucker production, fresh yield and dry recovery percentage were recorded. Growing degree days (GDD) for different phenophases was calculated by averaging daily maximum and minimum temperature and substracting base temperature of l3°C. The accumulated
heat sums (GDD) for the commencement of life cycle event was noted. GDD of different phenophases had a positive significant relationship with yield. On an average of 19,57 and 130 days for emergence of new shoot after planting and emergence of first and last suckers, respectively were observed that corresponds with heat sum of 278, 753 and 1660 degree days, respectively. Delayed planting produced more leaves and suckers than early planting. Higher fresh rhizome
yield (363.3g/plant) was harvested in 15th May planted crops, but the dry recovery percentage was. maximum (20.4%) with 30th April planting. The period between emergence to first sucker production is slow growth period and period between first sucker production and last sucker production is active ,growth period. The period beyond last sucker production is rhizome development and maturity phase. Accordingly weeding, fertilizer schedule, hilling and mulching has to be scheduled to harvest maximum yield of ginger.
