Abstract
1. Relating to the size of the seedling for set and their growing condition, a series of investigations was practised in two ways, the one was applying vinyl covering and multching as shelters and the other was non-shelter culture.
In a shelter plot, small sized seedling grow faster and flowered earlier than the bigger sized ones.
The shelter, when seedling are set, influenced more in growth of the plant than the size of the seedling.
Giving the seedling a better circumstance and making them grow smoothly, resulted in accelerating the growth and flowering.
2. An investigation was carried out to learn the relation between the pinch off the seedling in setting time and the growth after that.
By this, we found that the pinch off in setting time checked and delayed the growth and flowering, especially on an open field, it resulted in late flowering and low yield.
The pinch off to the young seedling lowed the flowering height a little, but this was not an effective method for accelerating the flowering.
