Experiments were conducted to study the influence of fertigation on growth and yield of broccoli and red cabbage under nethouse conditions during 2013-14 and 2014-15 at the University of Agricultural Sciences, Dharwad, India. The experiments were laid out separately for broccoli and red cabbage in a randomized block design with five treatments: T1, T2 and T3, fertigation with 50, 75 and 100% recommended dose of fertilizers (RDF), respectively, using water-soluble fertilizers (WSF); T4, fertigation with 100% RDF using conventional fertilizers; and T5, soil application of 100% RDF using conventional fertilizers. The mean of 2 years of data revealed that growth and yield parameters were significantly higher under T3 in both broccoli and red cabbage in terms of plant height (50.00 and 37.60 cm), plant spread (92.64 and 61.64 cm), number of leaves (24.75 and 31.15) and head yield (1.59 and 3.75 kg m‑2), respectively. However, yield in broccoli and red cabbage under T2 (1.51 and 3.66 kg m‑2, respectively) was on a par with that under T3, with higher benefit: cost (B:C) ratio (3.10 for broccoli and 2.72 for red cabbage). Soil application using conventional fertilizers generated the lowest growth and yield in broccoli and red cabbage during both years of study. In conclusion, fertigation with 75% RDF through WSF (T2) gave similar yields to 100% RDF and higher B:C ratio with 25% fertilizer saving for sustainable production of broccoli and red cabbage under nethouse conditions.
