Dalbergia sissoo Roxb. AND Gmelina arborea RoxbThe research work entitled “Effect of different watering frequencies on the seed germination, seedling growth and quality of two agroforestry species viz Dalbergia sissoo Roxb. and Gmelina arborea Roxb. “was undertaken at the Nursery site .Faculty of forestry, B.A.U. during the period from June, 2018 to November, 2018.The study was conducted with objective to study the germination, growth and quality of Dalbergia sissoo and Gmelina arborea at six different watering frequencies viz. Daily Watering (W1), Watering 3rd day (W2), Watering 6th day (W3), Watering 9th day (W4), Watering 12th day (W5) and Watering 15th Day (W6). To achieve the objectives the research was carried out under 4 experiments, each laid out in Completely Randomized Block Design, replicated three times and provided with six watering frequencies. Experiment 1 and 2 were conducted for studying the germination of Dalbergia sissoo (S1) and Gmelina arborea (S2) respectively where both the species germination was studied independently for one month. Seed germination of both the species were recorded on daily basis from each treatment. Experiment 3 with Dalbergia sissoo (D) and 4 with Gmelina arborea (G) were conducted for the study of growth and quality of seedlings of both the species under six watering frequencies. Results pertaining to the data of Experiment 1 (Dalbergia sissoo) and 2 (Gmelina arborea) showed that increasing intervals of watering frequencies delays the germination of seeds of both the species and also reduces the germination percentage and germination energy. In experiments 1 and 2 data recorded on commencement of germination showed that S1W1, S1W2, S1W3 are at par and significantly different from S1W6. In Gmelina arborea S2W1, S2W2, S2W3, and S2W4 (at par) are statistically different from S2W5, S2W6 which are at par with each other .EnglishThesis
