| Abstract | A multicrop upland seeder is designed by The International Rice Research Institute, Los Banos, Laguna, Philippines, which can be operated either by a power tiller or an animal power. For no tillage condition,
International Institute of Tropical Agriculture, Ibadan, Nigeria,
has developed a manually operated punch planter. Both of these machines have been evaluated under Philippines' condition and their economy
has been compared with the seeding method used by most of the Filipino farmers. Three crops were selected for the study purpose namely upland
rice, corn and mungbean. For rice, IRR! seeder sown plots had a better establishment in comparison to other two methods of seeding but there was no significant difference in yield in seeder sowing and traditional method of sowing. IITA punch planter showed a poor germination for rice
because seeds are not being covered by this machine. Weed infestation in no tillage system was much higher than the tillage system. Paraquat at a rate of 0.75 Kg a.i./ha is not sufficient to control the weed properly so some other herbicide or combination of herbicides are to be identified for a better weed control in no tillage system.
For corn IITA punch planter had a comparatively poor germination while in case of mungbean all the three methods of seeding performed satisfactorily. IRR! seeder is economic to use if more than one crop per year is seeded. IITA punch planter may be economical if some cheap and
more effective herbicide can be identified for better weed control, |
