Impact of tillage practices on crop growth and production in cotton under rainfed condition

Abstract

The field experiment is laidout during rainy season of 2014-15 at Central Research Station (CRS) of Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. To evalutate the impact of tillage practices on crop growth and production and economics in cotton. Layout of plots with six different treatments are 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). T3 (6.66q/ha) was more prominent and favorably influenced the growth, production and cost benefit ratio followed by T4(6.31q/ha), T6(5.83t/ha), T5(5.47t/ha), T2(5.22t/ha), T1(4.70t/ha).It can be summarized that sub surface tillage is one of the easily adaptable tillage practice for better crop growth and production under rainfed condition.
