Abstract

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 that either of the varieties did not give significant effect on N, P and K content in seed and straw of linseed. Irrigation at IW/CPR ratio of 0.7 gave significantly higher N and P content in seed and straw as compared of IW/CPE of 0.5 and 0.3. K content in seed and straw did not show significant effect with different irrigation schedules. 80kg N + 30kg P₂O₅ gave significantly higher in content in seed while 120kg N + 40kg P₂O₅ gave significantly higher P content in seed and straw. Effect of fertility levels on K content seed and straw was not found significant during both the year. Linseed variety recorded higher N, P and K uptake by seed and straw as compared to Rashmi. Irrigation at IW/CPE ratio of 0.5 gave higher N uptake by seed while in case of straw IW/CPE ratio 0.7 gave significant result. Irrigation at IW/CPE of 0.5 gave significant effect on P uptake by seed while irrigation at IW/CPE of 0.7 gave better result on P uptake by straw. Application of fertilizer at 80kg N + 30kg P₂O₅ha-1 gave significantly higher N & K uptake by seed while 120kg N + 40kg P₂O₅ha-1 gave significantly higher N uptake by straw. At fertility level 120kg N + 40kg P₂O₅ha-1 gave higher P uptake by seed and straw.
