All nutrients are placed in the root, thus better utilized. Sufficient space between pits will make operations like spraying, dusting and propping easy. Due to strong root growth, lodging is checked. • Sufficient and equal spacing between the clumps and rows allows sufficient light and air circulation improving the growth. • In case of drip irrigation, nutrition supplied through drip fertigation will help in faster crop growth • This method allows a farmer to pay individual attention to the crops or crop pits. • It gives better ratoon crops and has also been found useful under saline soils and saline water irrigated conditions. • All the shoots will be of the same age, so there is uniformity in growth and sugar accumulation in the canes. • The most important factor is that the seedlings are placed at a depth, which will be always moist, hence, in case of drought, or non-availability of water, the yields will not get affected.

Ratoon Management in Sugarcane Ratooning is a method where the lower parts of the plants along with the roots are left uncut at the time of harvesting. It is the most commonly followed and important practice in sugarcane cultivation. In ratoon crops, there is a saving in cost of cultivation in terms of land preparation, seed canes, etc. If ratoons are well maintained, they give high yields. But, for a better ratoon crop, a better plant crop is necessary. Avoid ratooning of pest and disease infected plant crops. Within a week after harvesting the plant crop, ratoon management practices like stubble shaving, off baring, gap filling etc., should be initiated. Stubble shaving • The stubbles just above ground level should be cut using a very sharp blade. • This helps the healthy underground buds to sprout and establish a deeper root system. Plant crops should be harvested when the weather conditions are conducive for stubble sprouting. • The deeper root system thus obtained facilitates optimum utilization of the nutrients and moisture available in the lower soil layers and provides good support for growth of the ratoon crop. Off baring • It is an operation wherein the ridges are broken or cut on either side using a plough. • This will loosen the soil to develop better root system and thereby better absorption of nutrients and water. Harvest of the plant crops should be done close to the ground level. Ratoon management Improving Sugarcane Cultivation in India 27
