This study establishes an important connection between farmers' concerns regarding sustainabl e farming and the adopt ion of improved technologies. Results from a formal on farm survey and rapid rural appraisals conducted in a drought prone area in Central India confirm that : (1) farmers are well aware of the effects of intensive cultivat ion of cash crops, such as sugarcane or cotton in irrigated tracts, in terms of reduced yields and increasing use of inputs; (2) appropriate crop/varietal adoption and manag -ement practices are consciously implemented to maintain long- term productivity levels for existing and desi red cropping systems; and (3) farmers strive to increase or ma intain soil fertility by inc luding nitrogen-fixing l egume s i n c rop rotat ions - i n this case, shor t -dur a t ion pigeonpea. Wide spread adoption of short -duration pigeonpe a has made farming profitable in the short term-via cultivation of a second crop in the post rainy season-and farmers expect to sustain productivity in the long run via crop rotation to maintain soil fertility.
