 ABSTRACT

The investigation was carried out at Floriculture and Landscaping Block, College of Horticulture, VCSG, Uttarakhand University of Horticulture and Forestry, Bharsar, Pauri Garhwal, Uttarakhand, India during March to September, 2017 to find out the effect of integrated nutrient management (INM) on vegetative growth, floral attributes, corm yield and economics of gladiolus var. Arka Amar along with effect on soil. The experiment consists of 8 (x 3) treatments in Randomized Complete Block Design. The minimum number of days taken to corm sprouts (17.27 ± 0.70 days), maximum number of sprouts corm-1 (2.40 ± 0.12) and number of leaves (9.80 ± 0.70) were recorded in treatment T7 i.e., 50% RDF + 50% FYM + Azotobacter @ 25 g L-1 + Trichoderma  harzianum @ 20 g m-2. The results also showed that earliness in spike emergence and first floret opening (87.00 ± 0.42 days and 95.30 ± 1.19 days, respectively), maximum days taken to full bloom of spike (24.73 ± 0.13),  spike length (101.30 ± 1.19 cm), rachis length (72.34 ± 0.97 cm), spike weight (92.84 ± 1.82 g), number of florets spike-1 (18.60 ± 1.06), number of spike plant-1 and  plot-1 (2.77 ± 0.03 and 29.33 ± 0.33, respectively)  and vase life (10.00 ± 0.19 days), number of corms plant-1 and corms plot-1 (3.00 ± 0.31 and 34.33 ± 1.45, respectively) were recorded in T7. However, maximum number of cormels plant-1 (44.08 ± 7.97), corm weight and diameter (1.24 ± 0.10 g and 5.10 ± 0.22 cm, respectively) were recorded in T6 and found statistically at par with T7 (40.93 ± 6.28, 1.10 ± 0.11 g and 4.83 ± 0.07 cm, respectively). With respect to soil parameters, treatment T7 recorded the maximum available organic carbon (1.40 ± 0.04 %,), available nitrogen, phosphorus and potassium (389.77 ± 2.03, 38.42 ± 2.85 and 257.24 ± 7.85 kg ha-1, respectively) content in soil after harvesting of corms and cormels. The most profitable treatment in terms of economics of cultivation was T7 with a cost: benefit ratio of 1:2.12.
