Effect of Slipping and Different Puddlings on Riding Type Transplanter Machine Performance

yyy This research was performed on the basis of a field experiment to evaluate the effects of puddling in machine slipping with three treatments and four replications. In order to determine proper transplanting, the variables such as planting depth, number of pigweeds in hill drop, row distance, hill drop distance, number of total lost hill drops and actual field capacity in one, two, and three times of puddling were measured. The seed of Belpanta variety of rice was for field tillage, the tiller ntav jl, /y ojlyJ, u Jj> l^jtfltf jsjb 4jb*/» (Kubota- KRA- 75) with 1.35 m work width, 7.5 hp was used. The riding type transplanter machine (Yanmar-pr-400) had 4 rows with 30 cm distance between rows. Treatment means were compared by Duncanʹs multiple range test. The results indicated that the number of puddlings increases slipping. There was no significant differences between five and three times of puddlings but the difference between three and one times puddlings was significant. One time of puddling was regarded the best conditions on the basis of transplanter performance but for weed burial three times of puddling was suggested. More than three times of pudding was not recommended because of technical and economical reasons.
