Abstract:
An experiment entitled “Effect of nutrient levels and planting geometry on yield, quality and economics of knol-khol (Brassica oleraceae var. gongylodes L.) under protected cultivation” was conducted during the Rabi and Summer season of 2021-22 at Agricultural and Horticultural Research Station, Madikeri, Karnataka. The experiment consisted of nine treatment combinations involving three levels of nutrient viz., 100, 125 and 150 percent RDF and three planting geometry viz., 30 cm × 15 cm, 30 cm × 20 cm and 30 cm × 25 cm was laid out in Factorial Complete Randomized Design with three replications. The result revealed that crop fertilized with 150 percent of RDF was recorded significantly higher diameter and fresh weight of knob per plant (7.29 cm and 181.38 g, respectively), knob yield (29.22 t ha-1), TSS content (7.09 0Brix), ascorbic acid content (41.80 mg 100 g-1), shelf life of knob (6.81 days), net return (Rs. 8,24,925 ha-1) and B:C ratio (3.40) which was on par with 125 percent of RDF. Among planting geometry, crop sown with a spacing of 30 cm × 25 cm was recorded significantly higher diameter and fresh weight of knob per plant (7.79 cm and 189.02 g, respectively), TSS content (7.29 0Brix), ascorbic acid content (42.89 mg 100 g-1) and shelf life of knob (7.06 days) whereas, significantly higher knob yield (32.96 t ha-1), net return (Rs. 9,71,977 ha-1) and B:C ratio (3.81) recorded with a spacing of 30 cm × 15 cm.
