An experiment was conducted to evaluate the effect of organic and conventional nutrient management on post harvest status of Broad Leaf Mustard (Brassica juncea var. rugosa) in field at Dakshinkali Municipality-2, Kathmandu, Nepal during the year 2016-2018. The experiment was laid out in a Randomized Complete Block Design. There were 13 treatments viz. T 1 (24 t ha-1. farm yard manure (FYM), T 2 (6 t ha-1. vermicompost), T 3 (4 t ha-1. poultry manure), T 4 (12 t ha-1 compost), T 5 (½ N: P 2 O 5 : K 2 O + 3 t ha-1 vermicompost), T 6 (¾ NPK + 1.5 t ha-1 vermicompost), T 7 (½ NPK+12 t ha-1 FYM), T 8 (¾ NPK +6 t ha-1 FYM), T 9 (½ N: P 2 O 5 : K 2 O + 2 t ha-1. poultry manure), T 10 (¾ N: P 2 O 5 : K 2 O +1 t ha-1 poultry manure), T11 (½ N: P 2 O 5 : K 2 O + 6 t ha-1 compost), T 12 (¾ N: P 2 O 5 : K 2 O + 3 t ha-1. compost) and T 13 (control) with three replications. In the study, maximum shelf life (8.67 days) was recorded in T6 (¾ N: P 2 O 5 : K 2 O + 1.5 t ha-1. vermicompost) and maximum organolaptic test score out of ten (7.72 Score) was detected in T 2 (6 t ha-1. vermicompost) while the maximum vitamin C (75.00 mg/100gm) and vitamin A (13.57 mg/g) were detected in T 5 (½ N: P 2 O 5 : K 2 O + 3 t ha-1 vermicompost)in green leaf of Broad Leaf Mustard.
