Abstract:
The present investigation on Response of organic manure on the growth and flowering behaviour of Gladiolus (Gladiolus grandiflora L.) cv. Summer sunshine under Chhattisgarh plains was conducted at Horticulture Nursery, Horticultural Research cum instructional farm, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during rabi season 2021-22. The experiment was laid out in Randomized Block Design (RBD) with two replications and 19 treatments. The treatment comprised of FYM 50 t/ha, Vermicompost 30 t/ha, Goat manure 20 t/ha, Mustard cake 500 g/m², Neem cake 500 g/m², Cow urine 20%, Cow dung wash 20% in different combinations including control (RDF 150:100:120 kg/ha). The result revealed that among all the organic manures and their combinations, treatment T₃ (FYM 50 t/ha + Mustard cake 500 g/m² + Cow urine 20%) showed best results in vegetative growth parameters like minimum days to 50% sprouting of corms (6.00 days), maximum plant height (42.79 cm, 77.45 cm at 30 and 60 DAP), maximum number of leaves plant^-1 (3.60, 8.50 at 30 and 60 DAP). However, flower yield parameters like minimum days to spike emergence (66.50 days), number of spike plant^-1 (2.30), spike length (71.20 cm), rachis length (45.31 cm), number of floret spike^-1 (15.80) were also recorded in treatment T₃ (FYM 50 t/ha + Mustard cake 500 g/m² + Cow urine 20%) as compare to other treatments.
