A field experiment was conducted at Agricultural Research Station Ummedganj, Kota. To find out the effect of fertility levels and irrigation schedules on Linseed varieties on vertisols of south-eastern Rajasthan during the year 2000–01 and 2001–02. on the basis of two years experimentation data show Result revealed that variety Meera consistently recorded significantly higher seed, Seed (15.39 qha ⁻¹), Straw (20.33 qha ⁻¹),Biological yield (35.72 qha ⁻¹), net monetary return (14620/ha) and B: C ratio (1.61) compared to as compared to variety Rashmi in linseed. Though the highest seed, Seed, Straw and Biological yield was recorded with IW/CPE ratio of 0.7 but it was found statistically art par with IW/CPE ratio of 0.5. Linseed variey Meera show significantly higher water use efficiency (7.81kg ha ⁻¹ mm) as compare to Rashmi (7.11 kgha ⁻¹ mm). The crop under influence of fertility level 80 kg N + 30 kg P₂O₅ha ⁻¹recorded higher water use efficiency (8.81 kgha ⁻¹ mm). The mean increase in water use efficiency at 80 kg N + 30 kg P₂O₅ha ⁻¹ was 20.62 and 87.84 per cent higher over 40 kg N + 30 kg P₂O₅ha ⁻¹ and control respectively.
