The present study was aimed to modify the existing animal drawn drum type seed cum fertilizer applicator. A seed cum fertilizer applicator was developed at FAE, IGKV, Raipur in the past years for the sowing operation of paddy in rows and it also maintain plant to plant distance along with fertilizer application, but some problems were observed during the operation of this machine. Dropping of seed and fertilizer from the drums encountered the problem of gathering of seeds in the chute. The seeds sown were left uncovered resulting in losses due to birds. Considering the above facts and studies, an attempt was made to modify the machine to overcome the problems, for that front half of the parabolic channel was made straight and placed at an angle of 35Ëš and a covering device is developed to prevent dropped seeds from birds as well as the machine was tested in laboratory and field. In laboratory testing seed rate and fertilizer rate was found as 18.39 kg/ha and 41.45 kg/ha respectively, During the field test the draft, operational speed, power requirement, seed rate and depth of seed placement were recorded as 456.36 N,2.36 kmph, 0.30 kW, 19.64 kg/ha and 4.72 cm respectively. The effective field capacity and field efficiency of the machine was found 0.151ha/h and 63.98%.The energy consumption and cost of operation was found 89.2MJ/ha and 578 Rs/ha. On the basis of the findings all over performance of the developed drum type seed cum fertilizer applicator was found better as compared to Indira seed drill and sowing behind the plough and the performance of the machine was found as per desirable.
