Abstract:
An investigation was carried out in the Department of Horticulture, in North Eastern Hill University, Tura Campus, Meghalaya (India) during 2019-2020 to study the response of Tuberose (Polianthes tuberosa Linn.) cv. Prajwal to application of FYM and the Vermicompost on vegetative growth, and flowering. The experiment was conducted to examine the performance of tuberose in organic amendments compare to inorganic fertilizer. The experiment consisted of 11 treatments and replicated 3 times in Randomized Block. The treatments were T₁: Control, T₂: Recommended dose of NPK (60:30:45 Kg/ha), T₃: FYM @ 25 tonnes/ha, T₄: FYM @ 50 tonnes/ha, T₅: FYM @ 75 tonnes/ha, T₆: vermicompost @ 10 tonnes/ha, T₇: vermicompost @ 20 tonnes/ha, T₈: vermicompost @ 30 tonnes/ha, T₉: FYM + vermicompost (25 tonnes/ha + 10 tonnes/ha), T₁₀: FYM + vermicompost (50 tonnes/ha + 20 tonnes/ha) and T₁₁: FYM + vermicompost (75tonnes/ha + 30 tonnes/ha). In terms of vegetative growth, result showed that T₁₁ significantly produced the earliness to days to 50% plant emergence (19.22 days), highest plant height (87.47 cm), numbers of leaves per clump (90.10), leaf area (207.82 cm²), number of plants per clump (11.91). In flowering character, earliness in emergence of spike (98.89 days), days to first floret opening (117.66), highest spike length (101.48 cm), rachis length (30.96 cm), highest florets/spike (39.76), floret diameter 4.29 cm, floret length (5.33 cm), number of spike/clump 5.72 and 49.44 per plot and maximum flower spike yield/ha was found maximum in T₁₁. Tuberose responded positively to all the parameters recorded in organic treatments and their combination than inorganic and control treatments. In the light of rising concerns for environmental and ecological impact of chemical inputs in agriculture, these organic amendments can be successfully used for ecofriendly crop production.
