Study on the compatibility of mechanical transplanting for short life varieties of rice [electronic resource].

Includes references.

In Egypt, rice transplanting is done by manual transplanting of rice seedlings in well-prepared puddled soil. At transplanting time, there is a sharp labor shortage. This results in increased labor wages, a delayed transplanting operation and non-uniform and inadequate seedling population. At last years, the rice breeding researchers produced short life and high production varieties of rice. These varieties are different in planting density compare With the old varieties. Therefore, the main objectives of this study were to study the compatibility of mechanical transplanting for short life varieties of rice and to determine the suitable mechanical adjustments of rice tranSplanter.To realize these objectives, three different p.t.o gear settings (70,80 and 90 hills/3.3 m ) and three cutting area of hill (120, 168 and 196 mm2) were applied under four different rice short life , varieties (Giza 177, Giza 178, Sakha 101 and Sakha 102) using the Japanese rice transplanter.
