A field experiment was conducted at Department of Vegetable Science, College of Horticulture, GKVK Campus, Bengaluru during Rabi Season of 2018-19 to study the effect of fertigation levels on available nutrients status of soil and nutrients uptake by cabbage. The experiment was laid out in RCBD with seven treatments replicated thrice. The treatments included three different dosages of fertilizer (100, 75 and 50% RDF) and each dose of fertilizers was applied in 12 and 6 equal splits at 5 and 10 days intervals, respectively and they were compared with soil application of 100% RDF (150: 100: 125 kg NPK ha-1). The phosphorus was applied as basal dose through soil application while nitrogen and potassium were applied through fertigation. The results revealed that application of 100% RDF in 12 equal splits at 5 days interval showed significantly lower pH of 5.84 and higher soluble salt content of soil (0.57 dS m-1). The soil application of 100% RDF recorded significantly maximum available nitrogen (340.93 kg ha-1) and phosphorus (47.93 kg ha-1) content of soil while significantly maximum available potassium content (146.50 kg ha-1) of soil was recorded with application of 100% RDF through drip in 6 equal splits at 10 days interval. The significantly maximum total uptake of NPK (159.85, 62.35 and 117.35 kg ha-1 respectively) by cabbage was recorded with application of 100% RDF in 12 equal splits at 5 days interval using water soluble fertilizers through drip.
