Effect of planting geometry and plant nutrition on growth, yield and quality of red cabbage (Brassica oleracea var. capitata f. rubra) under shade house condition



The field experiment was carried out at College of Agriculture, Vijayapur, University of Agricultural Sciences,Dharwad during kharif 2015 on Red cabbage hybrid Redma RZ F1 hybrid. There were nine treatment combinationscomprising of three spacing (S1: 45 cm x 30 cm, S2: 45 cm x 45 cm and S3: 45 cm x 60 cm) and three levels of fertilizer(F1,150:100:125, F2,175:125:150 and F3,200:150:175 kg N, P2O5 and K2O ha-1). The significantly higher red cabbage headyield of 36.0 t ha-1 and net returns of 4, 20,719 ha-1 with B: C ratio of 2.4. was achieved with the closer spacing of 45 cm x30 cm. Application of fertilizer at the rate of 200:150:175 kg N, P2O5 and K2O ha-1 (F3) produced significantly higher plantheight (23.3 cm), plant spread (51.9 cm), number of leaves (22.3), head diameter (10.9 cm), head weight (665.5 g), headyield (30.4 t ha-1) and highest net return of ` 3, 47, 614 ha-1 with B: C ratio of 2.3. Interaction effect of spacing and fertilizerlevels (S x F) revealed that, a spacing of 45 cm x 30 cm (S1) along with 200:150:175 kg N, P2O5 and K2O ha-1 (F3) resultedin significantly higher head yield of red cabbage (40.5 t ha-1), net returns ( 5, 07,680 ha-1) and B:C ratio (2.68) compared torest of the interactions.
