Kinnow mandarin (Citrus reticulata Blanco) belongs to family Rutaceae. In India, Kinnow is being grown in Punjab, Rajasthan, Haryana, Himachal Pradesh, Jammu & Kashmir and Uttar Pradesh. To evaluate the most profitable treatment, economic analysis of treatments was worked out in terms of net return and Cost benefit ratio (C: B) ratio. The cost incurred on basin preparation per tree (` 40), Cost of FYM per tree (` 60), Cost of Urea per tree (` 3), Cost of DAP per tree (` 12.60), Cost of MOP per tree (` 30) and

miscellaneous charges (Irrigation, plant protection measures, harvesting of fruits etc.) per tree (` 150) was found to be same in all the treatments. The cost incurred on the preparation of different solutions of potassium nitrate (KNO3) in various treatments was found to be ` 18.60 for 3.0 % KNO3 per tree followed by ` 12.40 for 2.0 % KNO3 and ` 6.20 for 1.0 % KNO3 and in preparation of different solutions of potassium sulphate (K2SO4) it was found to be ` 9.90 for 1.5 % K2SO4 per tree followed by ` 6.60 for 1.0 % K2SO4 and ` 3.30 for 0.5 % K2SO4. In case of preparation of ethrel in different treatments was found to be ` 6.75 for 450 ppm ethrel followed by ` 4.50 for 300 ppm ethrel and ` 2.25 for 150 ppm ethrel and the cost incurred for preparation of 75 ppm GA3 was found to be ` 22.60. It was found that 75 ppm GA3 treatment was best and showed highest net returns per tree ` 916.35. Thus, Kinnow mandarin trees treated with GA3 75 ppm was found to be best treatment combination as evidenced by cost: benefit ratio of 1: 3.88.
