Impact of tillage practices on water use and energy efficiency in cotton under rainfed condition

The field experiment was conducted at Central Research Station (CRS) of Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experiment field consist of 6 different treatments and 4 replications viz., conservation tillage (1 blade harrow before sowing) (T1), conservation tillage (1 Tyne+1 blade harrow) (T2), sub- surface tillage (90 cm H.I+2 Tyne+ blade harrow) (T3). Economical sub-surface tillage (1 sub surface +1 tyne+1 blade harrow) (T4), 1 Ploughing+ 2 Tyne +1 blade harrow (T5), Across the slope cultivation with opening of BBF after two row+2 tyne+1 blade harrow (T6). Water use efficiency was more dominant in treatment T3 (2.92kg ha-1mm-1), the energy efficiency is maximum for treatment T3 (3.7) followed by treatments, T4, T5, T6, T2 and T1.
