Abstract:
The present investigation entitled, “Study of Organic and Inorganic Fertilizer on Growth Yield Quality and Shelf Life of Gladiolus (Gladiolus Grandiflorus L.) cv. Priscilla” was under taken in the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. During rabi season (2021-2022). The experiment was layout in Randomized Block Design (RBD) with 10 treatments and each treatment replicated thrice. The treatments consist of different combinations of organic fertilizers (N, P and K) and inorganic fertilizers. The treatment T₆ (50% RDF + 50% Vermicompost) was found the statistically significant compared to other treatment combination, which recorded highest plant height (75.16 cm), number of leaves (12.59), leaf length (64.89 cm), leaf width (5.41 cm) followed by T₆ (50% RDF + 50% FYM). The treatment T₈ ((50% RDF + 50% Sheep manure) was found the statistically significant compared to other treatment combination, which recorded highest days to first spike initiation (earliness) (49.73 days), days to first floret initiation (earliness) (73.51 days), floret diameter (10.68 cm²), spike weight (35.6 g), vase life in normal tap water (13.26 days), spike per plant (2.61), number of spike per plot (33.67), number of spike per ha. (234332.3 Lakh), weight of single come (66.40 g), number of come per plant (2.85), corm yield per hectare (282221.5 lakh) followed by T₃ (25% RDF + 75% Vermicompost) and lowest yield was obtained from T₀ (control).
