- Intervention effect Trench sowing increased leaf area index, average crop growth rate and yield-contributing attributes compared with flat sowing.
- Association Weed population and biomass increased as the weed-crop competition period lengthened.
- Intervention effect Weed-crop competition for 45 DAS reduced stripped cane yield by 10.06% relative to zero competition in 2005-06.
- Intervention effect Weed-crop competition for 60 DAS reduced stripped cane yield by 17.90% relative to zero competition in 2005-06.
- Intervention effect Weed-crop competition for 75 DAS reduced stripped cane yield by 22.42% relative to zero competition in 2005-06.
- Intervention effect Weed-crop competition for 90 DAS reduced stripped cane yield by 28.65% relative to zero competition in 2005-06.
- Intervention effect Weed-crop competition for 105 DAS reduced stripped cane yield by 37.64% relative to zero competition in 2005-06.
- Intervention effect The full-season weedy check reduced stripped cane yield by 56.89% relative to zero competition in 2005-06.
- Intervention effect Weed-crop competition for 45 DAS reduced stripped cane yield by 9.84% in 2006-07.
- Intervention effect Weed-crop competition for 60 DAS reduced stripped cane yield by 18.76% in 2006-07.
- Intervention effect Weed-crop competition for 75 DAS reduced stripped cane yield by 22.92% in 2006-07.
- Intervention effect Weed-crop competition for 90 DAS reduced stripped cane yield by 27.98% in 2006-07.
- Intervention effect Weed-crop competition for 105 DAS reduced stripped cane yield by 38.75% in 2006-07.
- Intervention effect The full-season weedy check reduced stripped cane yield by 54.98% in 2006-07.
- Observation The critical period of weed-crop competition in sugarcane was 45 days after sowing.
- Recommendation The authors recommend trench sowing at 1.2 m row spacing as the better sowing technique.
