摘要

A metering system was developed for a precision cotton planter. The developed metering system plants two water soaked hybrid cotton seeds per hill. The exact size of the groove was selected based on the physical properties of the soaked cotton seeds. The metering mechanism of the precision cotton planter was evaluated in the laboratory for the seed distribution pattern at three angles of seed metering plate with horizontal (40°, 45° and 50°) and three forward speeds (2.0, 3.0 & 4.0 km/h). The 45° angle of inclination of seed metering plate with horizontal and forward speed of 3.0 km/h resulted into highest percentage of two seeds/drop (56.03 %), low percentage of no seed/drop (2.53 %) and one seed/ drop (15.43 %) and reasonably low percentage of more than two seeds/drop (26.01 %) as compared to other combinations. The developed precision cotton planter was evaluated in field at an angle of 45° of metering plate with horizontal and a forward speed of 3.0 km/h. The results indicated that field evaluation of developed metering system of precision cotton planter resulted in to 45.10, 27.13, 4.54 and 23.23 % germinated hills as singles, doubles, multiples and missing against the laboratory evaluation results of 15.94, 57.03, 27.01 and 2,53 %, respectively. The percentage of singles, doubles and missing for manual planting were 38.89, 27.78 and 33.33 %, respectively.
