Age of seedling

Age of seedling at transplanting has a direct bearing on the yield of the crop. In general, seedling having 3-4 leaves is considered ideal for transplanting.

The optimum age, however, depends upon the duration of variety, season, date of planting, system of raising nursery, tillering habit, inherent fertility and fertilizer management and cultural practices.

Method of planting

Transplanting in rice is done by two methods

  1. Random method: In the random method, seedlings are transplanted without a definite distance or space between plants.
  2. Straight-row method: The straight-row method follows a uniform spacing between plants. The seedlings are transplanted in straight rows.

Nursery raising method

Healthy and vigorous seedling establish themselves faster and grow better after transplanting and are important for getting high yield. Good seedling should be short, thick and heavy and free from pests and diseases. The major objective of nursery management should be aimed at obtaining such seedling. There are three methods of raising nurseries. These are dry nursery, wet nursery and dapog nursery.

Transplanting

 

Transplanting is the most common stand establishment technique adopted in wet system of cultivation. Nearly four-fifth of rice grown in the world is transplanted and almost all countries like Spain, Italy, Japan, etc. Where highest yields are recorded adopt only transplanting. Puddling is a pre-requisite for transplanting. Besides the benefits derived from puddling, transplanting in a puddle field offers a number of advantages

Time of transplanting

This starts with the appearance of first tiller after the emergence of 4/5th leaf. Tillers displace the leaf, from whose axil they emerge. Transplanting of seedling is recommended at this stage.
