Effect of integrated nutrient management on growth, flower yield and vase life of marigold (Var. Pusa Narangi)

Abstract

The experiment was conducted in the experimental area of the department of Horticulture, College of Agriculture, RVSKVV Gwalior (M.P.) with a view to certain the optimum requirement of NPK, FYM and Biofertilizer (PSB and Azotobacter). The experiment was laid out in a Randomized Block Design with eight treatments replicated thrice. The results revealed that application of the treatment of T8 (50% NPK+FYM+AZB+PSB) recorded maximum duration of flowering, flower diameter (19.77 days, 7.20 cm). Whereas application of T5 (75% NPK+FYM+AZB+PSB) produced significantly maximum branches, plant spread, fresh weight and dry weight of plant and flower (29.82 per plant, 0.357 cm, 413.28 gm and 85.20 gm per plant and 500.42 gm and 99.00 gm flower per plant respectively) and maximum shelf life and vase life of flower, both these treatments were statistically at par to each other. Treatment T5 showed maximum yield of flower recorded (312.76 q/ha) with maximum gross income (Rs.312700), net return (Rs.275843) and benefit cost ratio (7.48) followed by (50% NPK+FYM+AZB+PSB) T8 and gave best result in all respect.
