Abstract: The values of HTU are lower than PTU because of the fact that here in formula n value is taken into account while in PTU value of N is taken. There are more values of HTU in D1 to reach germination while in D2 least HTU are required. To reach flower initiation stage, highest number of HTUs are required while least HTUs are required in normal sowing or second growing environment. It can be very well observed that the highest HTUs are required in Vaibhav while equal number of HTUs are required in JG-14 and JG-16. Similarly in 50% flowering, 100% flowering, pod formation least HTUs are required in second growing environment and JG-14/ JG-16 alike. PTU for different growing environments and varieties are shown in Table no. It can be seen from the table that there are more PTUs generally in first growing environment to reach germination, flower initiation, 50% flowering and 100% flowering. Among the varieties also there are differences and more degree days are required for Vaibhav while lesser PTUs are required in JG-14 and JG-16. The GDDs affected by the growing environment and varieties. It can be seen that GDDs to reach germination stage are higher in D1 and go on decreasing with the delay in sowing. In general GDDs for first growing environment are 183 but with delay in growing environment, the GDDs values reach 170 in second growing environment and reach 159 by the third growing environment. To reach flower initiation stage, lesser GDDS are required for D3 i.e. third growing environment while maximum, GDDs are required in first growing environment.
