Rice Transplanting

Rice Transplanting

Transplanting

       Transplanting should be done when seedlings are ready for transplanting. The seedings are uprooted from the nursery at the optimum age (three to four weeks for short duration varieties and four to five weeks for medium and long duration varieties). Transplanting of the healthy seedlings may be done at the four to five leaf stage or when they are about 15-20 centimeter high. Delayed transplanting leads to poor tillering, early flowering of the main tillers and reduction in yield. Transplant two to three seedlings per hill at 20 × 10 centimeter distance under normal conditions. Increase the number of seedlings per hill if old seedlings are used. For 45 days old seedlings the number of seedlings per hill should be five or six. In alkaline soils old seedlings (45 days old) establish better than young seedlings of 25 days ago or so. In each case seedlings should be transplanted at 2-3 centimeter depth. Seedlings should not be planted deeper planting delays and inhibits tillering. Planting in lines may not be necessary if adequate population is assured. There should be on an average, 50 hills per square meter to assure adequate population in rice field.

            In wet or lowland cultivation of rice, transplanting is advantageous for the following reasons:

  1. It enables the cultivator to have optimum plant population at desired spacing in the field.

  2. It enables the cultivator to have an opportunity to give a thorough cultivation and pudding operation th the field which keeps down the weeds.

  3. Since the nurseries occupy only a small area of the field, the control of diseases and insect pests and irrigation and manuring of young crop is easier and cheeper than a broadcast or direct sown crop.

     But now a days transplanting has become very expensive due to high labour cost. A number of field experiments have shown that the productivity of direct seeded rice could be as high as from transplanted rice provided the weeds could be controlled effectively and the management level are high.
