Abstract:
A research was conducted at Instructional Farm, Polytechnic in Horticulture, Junagadh Agricultural University, Junagadh with an objective to determine the effect of different doses of NPK fertilizers and split applications on yield of dragon fruit. The selected plants were subjected to different fertigation schedules during April, 2021 to February, 2022. The treatments comprised of four levels of NPK fertilizer doses (F) viz., F1 = 450: 250: 250 g NPK/pillar, F2 = 450: 350: 300 g NPK/pillar, F3 = 500: 750: 300 g NPK/pillar and F4 = 550: 800: 350 g NPK/pillar, with five levels of split application (S) viz., S1 = 2 splits, S2 = 3 splits, S3 = 4 splits, S4 = 6 splits and S5 = 8 splits. Among different treatments, the application of soluble chemical fertilizers @ 500: 750: 300 g NPK/pillar improved the yield of dragon fruit. Similarly, 4 split application of fertilizers (in April, July, October and January) improved yield of dragon fruit. Thus, the combined application of soluble chemical fertilizers @ 500: 750: 300 g NPK/pillar with 4 split applications (in April, July, October and January) through fertigation, improved yield and yield attributing characters of dragon fruit.
