Fertilizer Reduction Techniques on Growth and Yield of Cabbage (Brassica oleracea var capitata L.)

An investigation was carried out to find out the effect of reduction in RDF through foliar application of water-soluble fertilizers on the growth and yield of cabbage. The result showed that the growth and yield parameters significantly varied with a reduction in RDF through foliar application of water-soluble fertilizers at different concentrations. The maximum plant height (15.83 cm), number of loose leaves (15.85), leaf length of outer leaf (22.46 cm), leaf breadth of the outer leaf (22.48 cm), leaf area (504.90 cm2), and weight of loose leaves per plant (549.98 g) and yield parameters like maximum weight of head (0.96 kg), fresh weight of five heads (4.80 kg), head diameter (15.78 cm), yield per plot (33.54 kg ), total yield (54.09 tha-1)  and highest marketable yield (53.26 tha-1) were recorded superior in the treatment T9 (66 % RDF + 2.5 % F A) in all growth and yield parameters with foliar sprays of water-soluble formulation NPK 19:19:19 sprayed at 3 times compared to check treatment T13 (100  RDF% alone) and all these parameters are minimum in T1 (33 % RDF + 2.5% FA).
