Agronomic techniques for raising spring sugarcane

摘要

Sugarcane is an important commercial crop grown under wide range of climate, ranging from sub-tropical to tropical conditions. However, the crop yield is substantially higher in tropical regions as compared to the sub-tropical regions due to more favourable climatic conditions for its growth. In Punjab, it was grown on an area of 92 thousand hectares during 2016-17 both as autumn and spring season crops. Spring crop occupies a large area. However, autumn crop gives 15-20% higher cane yield and sugarrecovery on account of extended growth periods and thus is more remunerative as compared to spring crop. Spring crop is generally planted after harvesting of potato, green peas, rabi fodder and oilseed crops from mid February onwards. It's planting is delayed at times even up to the month of May after harvesting of wheat. Since it is a perennial crop, it remains in the field 2-3 years and its agronomic practices are different from those of other crops. Adoption of improved agronomic techniques plays a pivotal role in realization of potential yield of the crop.
