| dc.description.abstract | Rice (Oryza sativa L.) is important leading food crop and it is widely cultivated in India. The farmers are facing problems due to lack of labour, time, inputs cost and also due to drudgery in work. Nevertheless, mechanization in paddy cultivation can boost higher productivity and considerably reduce the cost of production. Therefore, the present study was undertaken to design and develop a power operated paddy hill seeder in paddy cultivation. The power operated paddy hill seeder was developed and tested based on the, engineering and physical properties of dry and pre-germinated paddy seeds. The tests were conducted on sand bed to evaluate the seed metering mechanism performance with respect to spacing, seed rate, quality of feed index, multiple index, miss index, and seed damage at two different forward speeds (1.5 and 1.8 km h-1), two cell sizes and three transmission speeds (1:1.7, 1:1.2 and 1:0.95). The mean hill to hill spacing was ranged from 0.09-0.20 m, 3 to 7 seeds per hill, seed rate of 21-58 kg ha-1. The missing index and multiple indexe were less for the different combinations of study parameters (speed 1.5 kmph, cell size 9 mm, Transmission ratio 1:1.7), (Speed 1.8 kmph, Cell size 9 mm, Transmission ratio 1:1.7) and (Speed 1.8 kmph, Cell size 12 mm, Transmission ratio 1:1.7). The quality feed index were 86.1, 88.6 and 91.1 respectively for above sequence of combinations of study parameters. The average field capacity of the paddy hill seeder was 0.22 ha h-1 and 0.26 ha h-1 with efficiency of 80.00% and 76.00 % for forward speeds of 1.5 and 1.8 kmph respectively. Based on the performance evaluation results, it is concluded that the developed power operated paddy hill seeder is economical and efficient for direct sowing of paddy. | en_US |
