The response to irrigation and fertility levels in the lentil variety JLS-1 was studied during three growing seasons from 1974 to 1977. Two double irrigation schedules were studied; the first with one irrigation at the pre-flowering stage and one at pod-filling, and the second with one irrigation at pre-flowering and one at post-flowering. Both schedules gave higher seed yield; the first gave 1590 kg/ha and the second gave 1570 kg/ha, with additional returns of Rs 1963 (US Dollar 1 = Rs 12.75) and Rs 1903/ha, respectively. A single irrigation at pre-flowering increased seed yield by 10.0, 24.0 and 50.6%, respectively, over the application of one irrigation at post flowering, pod filling stage, and control (no irrigation). This schedule provided an additional return of Rs 1214/ha. Fertility level of 25 kg N + 50 kg P2O5/ha with inoculation gave significantly higher seed yield than all other levels with Rs 333/ha of additional economic return over the control. Application of two irrigations -one at pre-flowering and one at post-flowering stages at a higher fertility level - showed an increase in seed yield of 134.1% over the control (no irrigation or fertilizer)
