Methods of Planting Rice 1 This is one of the rice production training modules produced by the International Rice Research Institute. 2 This module is on the methods of planting rice. 3 At the end of this lesson, you will be able to • discuss two general methods of planting rice. • list the advantages and disadvantages of each method, and • explain the factors affecting proper spacing and its importance in transplanted rice. 1 4 There are two methods for planting rice: transplanting and direct seeding. 5 Seedlings are prepared by any of the three methods described in Methods of Raising Seedlings. The seedlings are now ready for transplanting in the field. Transplanting is done in one of two methods: random or straight-row. 6 In the random method, seedlings are transplanted without a definite distance or space between plants as you can see in this frame. 7 The straight-row method follows a uniform spacing between plants. The seedlings are transplanted in straight rows. 2 8 You will need planting guides to have uniform spacing. Planting guides are made of wire, twine, and wood. Set the planting guides in the field before transplanting. 9 In this method, make sure the roots and base of the seedlings are inserted into the soil right under the loop or mark on the planting wire. 10 After planting one row of seedlings, move the guides to the next row and then continue planting. Move backward for each subsequent row. 11 Plant the wetbed seedlings at a depth between one and a half to three centimeters. The dapog seedlings are planted at one and a half centimeters deep or just deep enough for the roots
