Abstract

The present investigation was undertaken under net house conditions with an objective to study the effect of spacing, nitrogen and phosphorous on growth, flowering and yield of heliconia cv. Golden Torch at Floriculture Research Scheme, ASPEE College of Horticulture and Forestry, NAU, Navsari, Gujarat, India during the year 2007-08.The experiment was laid out in a Randomized Block Design with Factorial concept (FRBD) with three replications and twenty-four treatment combinations, comprising of two levels of spacing (S₁=50 x 40 cm and S₂=75 x 40 cm), four levels of nitrogen (N_o=00, N₁=100, N₂=200 and N₃=300 kg N/ha) and three levels of phosphorus (P_o=00, P₁=50 and P₂=100 kg P₂O₅/ha). The potassium @ 100 kg/ha and FYM @ 5 kg/m² were applied as a common dose. The collected data was analysed by adopting ‘Analysis of Variance’ technique and the experimental results revealed that, among spacing treatments, planting of heliconia at a spacing of 50 x 40 cm (S₁) enhanced growth, yield and quality parameters as compared to those planted at 75 x 40 cm (S₂). Whereas, in case of nitrogen and phosphorus fertilizers, application of 300 kg N/ha and 100 kg P₂O₅/ha, respectively were found to significantly increased the growth, yield and quality parameters as compared to other levels. Among the different interactions, the significant effect of S x N interaction for number of suckers per clump at 9 MAP, number of flowers per clump and flower yield per hectare was obtained with the treatment combination of S₁N₃. Similarly, S x P interaction was found significant for number of flowers per hectare which were higher under S₁P₂. Likewise, the significant effect of N x P interaction was also obtained for number of suckers per clump, number of bracts per flower and flower yield per hectare with better shelf life with the treatment combination of N₃P₂. Hence it can be concluded that, for obtaining higher yield and flower quality,heliconia cv. Golden Torch should be planted at 50 x 40 cm spacing and fertilize with 300:100:100 kgNPK per hectare.

Abstract

The investigation was carried out during the year 2011-12 at the Horticultural Research Farm, Department of Horticulture, B.A. College of Agriculture, Anand Agricultural University, Anand to assess the role of different concentration of GA₃ and conditions on seed germination, vegetative growth of acid lime cv. KAGZILIME. The experiment was laid out in Factorial Romized Block Design with twelve treatments and four replications. The fresh, moderate uniform in size and viable seeds of Kagzilime were treated (soaked) with six different levels of GA₃ for 12 hours and sown in prepared raised seed bed in the field and net house condition. The results revealed that the seeds treated with 500 mg/l GA₃ took significantly less time for 75 per cent germination (29.25 days) as well as recorded maximum germination (83.50 %), plant height (24.33 cm), number of leaves (30.03), length of seedling (36.48 cm), thickness of primary ischolar_mains (2.07 mm), girth of seedling at top (1.01 cm), middle (1.00 cm) and bottom (1.14 cm), fresh weight of seedling (20.81 g), dry weight of seedling (11.58 g), total leaf area of seedling (8.28 cm²) as well as survival (74.45 %) at 120 DAS, respectively as compared to rest of the treatments. The results also indicated that the seeds sown under the net house conditions took significantly less time for 75 per cent germination (32.58 days) as well as recorded maximum germination (79.04 %), plant height (22.00 cm), number of leaves (26.50), length of seedling (34.96), thickness of primary ischolar_mains (2.00 mm), girth of seedling at top (0.98 cm), middle (1.09 cm) and bottom (1.13 cm), fresh weight of seedling (18.92 g), dry weight of seedling (10.07 g), total leaf area of seedling (7.95 cm²) as well as survival (71.38 %) at 120 DAS, respectively as compared to open field condition (C₁). In case of interaction between levels of GA₃ and conditions, significantly the maximum number of leaves (11.75 at 30 DAS), thickness of primary ischolar_mains (2.26 mm at 120 DAS), fresh weight of seedling (15.70 g at 90 DAS), dry weight of seedling (5.53 g at 90 DAS) and survival percentage of seedling (80.01% at 120 DAS) recorded under the treatment G₅C₂ (GA₃ 500 mg/l under net house conditions).
