The study has quantified and compared the effect of laser land levelling technology with conventional land levelling in paddy-wheat and cotton-wheat cropping pattern in Karnal and sirsa district of Haryana state, respectively. Using Bisaliah decomposition model (1977) improved technology and change in input use to enhance productivity under laser land levelling has been assessed. Decomposition of total productivity highlighted that in Karnal district, out of total incremental change in productivity, 8.38 and 5.36 per cent change was contributed only due to change in technology and rest was due to input use in paddy-wheat, respectively. Similarly, in Sirsa district, out of total change in productivity 5.4 and 4.87 per cent change contributed only due to enhancement in technology while rest was due to input use in cotton-wheat cropping pattern, respectively. Further study highlighted that water as well as fertilizer use efficiency was most influenced by use of laser land levelling technology. On the account of results of study, it was concluded that laser land levelling is an effective scale neutral resource conservation technology which has immense potential to cure low water use efficiency and improve fertilizer use in most prevalent cropping patterns (i.e. paddy-wheat as well as cotton) of Haryana state.

Highlights

• Major contribution in total productivity was due to technological change by adoption of laser land levelling technology followed by input use.
