Results indicated that, with conservation furrow, a sole soybean yield of 1504 kg/ha was
obtained with a yield advantage of 302 kg/ha over the treatment of no conservation furrow
(1202 kg/ha). The net returns of Rs. 22571/ha was obtained due to adoption of conservation
furrow technique and found to be higher than the net return of Rs. 18609 in no furrow system.
The BC ratio under adoption of conservation furrow technique was found to be 2.14 as against
BC ratio of 1.72 with no furrow system. Similarly, the RWUE of 3.19 was found with
conservation furrow as compared to RWUE of 2.50 in no furrow system. The effect of in-situ
moisture conservation practice like conservation furrow in sole soybean on crop productivity
(yield), net monetary returns, BC ratio and RWUE was analyzed and the data is presented.

In soybean + pigeonpea (4:2) intercropping system, an additional soybean equivalent yield of
462 kg/ha was obtained with adoption of conservation furrow technique as compared to no
furrow with net monetary benefit of Rs. 11897/ha. The increase in yield and net return is due
to 30 per cent more moisture conservation resulted in better crop growth and crop performance
even during dry spells.
