Design and development of sri single seedling transplanting implement with seedlings in semi-dried clay media

In rice production, seedling quality and transplanting potentials stand as a prerequisite for the proper completion of rice production operations in securing optimum yield. The overall objective of this research was to develop a transplanting implement capable of placing rice seedling singly i...

The overall objective of this research was to develop a transplanting implement capable of placing rice seedling singly into the field by dropping through a gated opener with respect to SRI planting and spacing conditions deprived from the existing methods of picking fingers by the conventional transplanting machines.

Accordingly, it has been set to provide nine SRI spacing options (25 cm × 25 cm, 25 cm × 30 cm, 25 cm × 40 cm, 30cm × 30 cm, 30 cm × 40 cm and 40 cm × 40 cm, respectively).
