Sesame (Sesamum indicum) is a short-day plant and generally requires fairly hot conditions for its optimum growth and yield. Crop growth and development are closely related with growing degree days. Therefore, growing degree days (GDD) requirement for different phenological stages of sesame cv. RT 127 was studied during the kharif seasons of 2010 and 2011 at the Research Farm of Central Arid Zone Research Institute, Jodhpur (Rajasthan). Plant height increased with accumulation of GDD and attained an height of 124 cm after receiving an accumulated GDD of about 1266 C-day during 2010 and similarly, plant height of 132 cm was observed corresponding to 1240 C-day accumulated GDD during crop season 2011. 80 leaves plant-1 were observed corresponding to an accumulated GDD of 970 C-day during crop season 2010 and 92 leaves plant-1 corresponding to 1094 C-day accumulated GDD during 2011. For initiation flowering stage, higher accumulation of GDD (852 C-day) was observed in 2011 as compared to 2010 (673 C-day) crop season. Higher amount of GDD was also observed for physiological maturity in 2011 than 2010. The significant difference in GDD in the year of normal and late sowing year was also proportionately reflected at 50 and 100% flowering. Hence, study revealed that amount of GDD received in sunny day plays an important role for crop growth and maturity rather than days after sowing. An effort on establishment of relationship between GDD and growth and development of sesame crop may be helpful in developing new varieties matching with shifting climatic patterns. Not Available |
