A field experiment was conducted at the Dryland Farming Research Station, Arjia, Bhilwara during kharif seasons of 2010 and 2011 with an objective to find out a suitable in-situ moisture conservation practice for blackgram to enhance productivity. Results of the study revealed that raised bed of 40 cm width with summer deep ploughing produced the higher blackgram seed yield of 1239 kg ha⁻¹ with B: C ratio of 3.33 and water use efficiency of 2.01 kg ha⁻¹ mm⁻¹. Blackgram seed yield increased from 82% to 118% compared to other moisture conservation practices and control. Summer deep ploughing alone increased blackgram seed yield by 16% to 21% overshallow tillage. Lower run off and soil loss wasrecorded in raised bed of 40 cm width with summer deep ploughing. Additional cost of cultivation of 500 ha ⁻¹ incurred in formation of raised bed of 40 cm width compared to raised bed of 70 cm width and produced additional net returns of 2.19 ha⁻¹ rupee⁻¹ of investment.
