Abstract
Experimentally it was found that the traditional method of sowing leads to unsatisfactory plant population which in turn affects the yield per hectare. Beside, this, in the traditional method the seed requirement is 10 to 20 % higher and thinning is required to get desired plant population. Groundnut, therefore, required a planter for accurate seed metering and regulating,plant to plant spacing in row. Till to date animal drawn groundnut planter is not available which can perform the above mentioned functions satisfactorily. Keeping the above facts in view a project on design and development of animal drawn groundnut planter was under taken at Department of Farm Engineering, Gujarat Agricultural University, Junagadh Campus, Junagadh.The designed and developed groundnut planter was tested both at laboratory as well as field level. The seed rate, mechanical damage and viability of seeds were tested in the laboratory. The seed rate for groundnut varieties JL-24 and GAUG-1 were found to be 103 kg/ha and 101 kg/ha respectively, Whereas the mechanical damage of both the varieties JL-24 and GAUG-1 were 0.77 % and 0.61 % respectively. The viability of seed from the planter was satisfactory. During field testing of the planter, the power requirement, depth of placement of seeds in the furrows, uniformity and spacing were determined. It was found that the draft required to operate this planter was 26.31 kg with the speed of 2.2 kmph (.0,61 m/sec). The average power required to operate the planter was 0.213 hp. The depth of placement of seeds v/as uniform as y.O cm, whereas the number of seed in 5 m length of furrow and spacing between two seeds v/ere observed for all the three furrow openers which varied from 51 to 53.7 seeds and 9.3 cm to 9.6 cm respectively. The theoretical field capacity of the planter was observed as 0.296 ha/hr, while the effective field capacity and field efficiency were determined as 0.202 ha/hr and 68,24 % respectively. Only one labour is required to operate the planter.Based, on the above results, this planter would be very useful to the farmers for sowing the groundnut seeds at proper seed rate and required spacing there-by help in increasing the groundnut production.
