EFFECT OF SOWING DEPTH AND EARTHING UP ON LODGING IN PRESOWN SUGARCANE

Abstract

The field studies on management strategies for controlling lodging in presown sugarcane were carried out at Sugarcane Research Station, Khanpur during 2004-05 and 2005-06. The management practices included two sowing techniques i.e., shallow furrows, deep trenches and three earthing up treatments i.e., no earthing, earthing up with spade and earthing up with ridger. The results indicated non-significant cane yield improvement due to trench sowing and significant due to earthing up. Spade earthing increased cane yield by 19.20 % and earthing up with ridger increased by 18.00% over no earthing control in pool analysis. A measurable increase in commercial cane sugar was recorded owing to earthing up as a result of reduced lodging.
