Abstract:
An investigation was carried out to find out the response of organic manures on growth and flowering parameters of tuberose (Polianthes tuberosa L.) cv. Phule Rajani at BTCC, Orissa University of Agriculture and Technology, Bhubaneswar, Odisha during the period 2015 to 2016. The trial was conducted with ten treatments viz. T₁ (Control), T₂ (Vermicompost @ 2 kg/ m²), T₃ (Mustard oil cake @500g/m²), T₄ (Karanja oil cake @500g/m²), T₅ (Neem oil cake @ 500g/ m²), T₆ (Groundnut oil cake @500g/m²), T₇ (Vermicompost @ 1Kg/m² + Mustard oil cake @ 250g/m²), T₈ (Vermicompost @ 1Kg/m² + Karanja oil cake @250g/m²), T₉ (Vermicompost @ 1Kg/m² + Neem oil cake @250g/m²) and T₁₀ (Vermicompost @ 1Kg/m² + Groundnut oil cake @250g/m²). The experiment was laid out in Randomized Block Design with three replications. The result of the study revealed that, application of organic manures obtained significant differences in vegetative and flowering parameters of the plant. Among all the organic manures and their combinations treatment T₇ (Vermicompost @ 1Kg/m² + Mustard oil cake @250g/m²) recorded the maximum value for vegetative growth parameters like, plant height, plant spread, number of leaves per plant, leaf length, breadth and leaf area; Maximum value for floral characteristics like, number of spike per plant and number of florets per spike were recorded in treatment T₈ (Vermicompost @ 1Kg/m² + Karanja oil cake @250g/m²) compared to other treatments. It is therefore suggested that better quality spikes under organic farming can be obtained with application of T₇ (Vermicompost @ 1Kg/m² + Mustard oil cake @250g/m²) and T₈ (Vermicompost @ 1Kg/m² + Karanja oil cake @250g/m²) respectively in tuberose cv. Phule Rajani.
