Influence of nitrogen application frequency on yield and economics of drip irrigated potato (Solanum tuberosum L.) Cv. Kufri Bahar

The present investigation was carried out to find the effect of frequency and dose of nitrogen fertigation on growth and yield of potato and to calculate the economics of different treatments investigated. | Int.J.Curr.Microbiol.App.Sci 2017 6 5 753-758 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 5 2017 pp. 753-758 Journal homepage http www.ijcmas.com Original Research Article https doi.org 10.20546 ijcmas.2017.605.085 Influence of Nitrogen Application Frequency on Yield and Economics of Drip Irrigated Potato Solanum tuberosum L. Cv. Kufri Bahar Vikram Ghiyal and A.K. Bhatia Department of Vegetable Science College of agriculture CCS Haryana Agricultural University Hisar-125004 India Corresponding author ABSTRACT The present investigation was carried out to find the effect of frequency and dose of Keywords nitrogen fertigation on growth and yield of potato and to calculate the economics of different treatments investigated. The experiment comprising of four levels of nitrogen Drip irrigation i.e. 90 N1 120 N2 150 N3 and 180 N4 kg ha and three fertigation frequencies i.e. Economics every 3rd day F1 every 6th day F2 and every 9th day F3 was laid out in a Randomized Fertigation Block Design with three replication. The total tuber yield 296.50 q ha biological yield frequency 402.11 q ha marketable yield 270.28 q ha and harvest index 67.58 were significantly Nitrogen and higher when fertigation applied at every 3rd day F1 . Nitrogen levels exhibited significant Potato. difference for growth and yield. The maximum value for total tuber yield 292.33 q ha Article Info biological yield 404.17q ha marketable yield 267.66 q ha and harvest index 67.40 were maximum with the application of nitrogen @120 kg ha N2 . Interaction effect of Accepted fertigation frequency and nitrogen levels showed remarkable variation. The maximum total 04 April 2017 tuber yield 307.78 q ha biological yield 428.17 q ha and marketable yield 280.79 q ha . Available Online Significantly higher marketable tuber yield 280.79 q ha maximum net return Rs. 10 May 2017 1 17 488 ha and benefit cost ratio 1.75 was found highest with F 1N2 treatment combination. .
