Abstract:

The study was under taken to design and develop a mechanical and electronic precision planter for paddy direct seeding and compared for optimum seed rate, germination, seed placement index and spacing. The comparison o of two methods was done in terms of seed rate, spacing and seed placement index The observe seed rate, spacing and seed placement index values of mechanical and electronic methods were 22.7 kg/ha, 14.4 cm and 74.3% and 19.97 kg/ha, 14.8 cm and 86.39%, respectively. A saving of 12.04%, in seed rate was observed by sowing with electronic metering method over mechanical. The variation in spacing was less than 4.0% as compared to mechanical method of sowing. The seed placement index was found to increase by 16.3% with electronic metering. Thus based on the results of seed rate, spacing and seed placement index, it is imperative to say that electronic metering leads to better precision as compared to mechanical sowing. The Seed Placement Index (SPI) and percentage of one and two seeds per hill, increased up to a forward speed of 2.0 km/h and 350 angle of inclination and thereafter decreased significantly. The breakeven point and payback period of developed precision planter was 95 h/year and 2.5 years respectively; very close to that of mechanical planter for which the values were 88 h/year & 2.3 years respectively.
