Optimal tillage depths for enhancing rice yield, quality and lodging resistance in the rice production systems of northeast China.

ABSTRACT: Long-term shallow tillage leads to poor development of root system and deterioration of soil quality. Field experiments were conducted during 2019-2021 to explore the effects of different tillage depths on rice root system, stem lodging resistance, rice yield and quality. The experimental treatments were comprised of four tillage depths i.e., 14 cm (TD 14) as the control, 17 cm (TD17), 20 cm (TD20), and 23 cm (TD23) by using a tractor- mounted hydraulic-adjustable. Results indicated that the TD17 treatment substantially improved the breaking resistance by 39.45-72.37% and decreased the lodging index by 11.73-29.94% of first to third node attribute, increased the stem diameter and unit length dry weight and decreased the internode length, compared with control. The TD17 treatment als
