Design Type
Randomized complete block design
Description
Until 1999 wheat stubble was incorporated before sowing cotton, whereas from December 1999 cotton was sown with no-tillage into wheat stubble. From 2000 Roundup-Ready cotton was grown.
Design description
Plots measured 190 m long and 36 rows wide.

tillage process
conventional tillage  (30 cm depth)
Application method: chisel plough
Applied to continuous cotton only. Cotton plants are slashed after harvest followed by disc-ploughing and incorporation of cotton stalks to 20 cm followed by chisel ploughing to 30 cm followed by 1-m bed construction.
minimum tillage
Cotton plants are slashed after harvest followed by root cutting incorporation of cotton stalks into beds and bed renovation with a disc-hiller.
