Abstract

The experiments were carried out during 2014 seasons at Sakha-farm research to evaluate performance of modification transplanter for cotton seedling. The experiments were conducted using a modification transplanter to evaluate the effect of forward speed of 1.88, 2.35, 2.95 and 3.38 km/h, hill spacing of 0.15, 0.2, 0.25 and 0.3 m and planting depth of 8, 10, 12, 15 cm. the present work was used to study the effect of previous variables on effective field capacity, field efficiency, longitudinal and transverse seed scattering, ground wheel slip, germination ratio, seedling miss index, the seedlings multiples index, the quality of feed index, the amount of seedling rate and crop yield. Also, determination of specific fuel consumption, operating and criterion function cost of cotton transplanting were done. Results illustrated that by increasing planting forward speed actual field capacity, affective field efficiency, both of longitudinal and transverse scattering, slip ratio, seedling miss index, the quality of feed index and criterion function cost were increased. While, seedling multiple index, specific fuel consumption, productivity and total operation cost were decreased. Maximum of effective field capacity, field efficiency, productivity, specific fuel consumption and the quality of feed index were 0.739 fed/h, 83.1%,7.61 kantar/fed, 0.731 L/kW.h and 92.3% respectively. While, minimum of longitudinal scattering, transverse scattering, slip ratio, seedling miss index was and seedling multiple index were 0.016 m, 0.010 m, 7.42%, 2.1% and 4.0% respectively. The optimum operation condition of machine transplanting was obtained at forward speed of 2.95 km/h, hill spacing of 0.25 m and planting depth of 8 cm.
