    INFLUENCE OF EDAPHIC FACTORS ON GROWTH AND YIELD OF FOREST SEEDLINGS IN RANCHI, JHARKHAND
    (Birsa Agricultural University, Ranchi, 2019) Mahato, Ashok Kumar; Mahto, M.
    The research entitled with ‘’Influence of Edaphic factors on growth and yield of forest seedlings in Ranchi, Jharkhand’’ to find out the maximum growth and yield of the tree species in the available soil conditions of the site. Forest department of Jharkhand has done the reforestation work in the site located at Bhusur (Ormanjhi), 30 km away from Birsa Agricultural University campus, in the year 2017 with four different tree species, namely Acacia, Chakundi, Bakain and Teak. The purpose of reforestation is to meet the demands of the local inhabitant and to check the site against soil erosion. The current experiment was carried out using RBD experimental design taking 4 treatments (T1 is Cassia siamea, T2 is Acacia auriculiformis, T3 is Melia azedarach and T4 is Tectona grandis ) and 5 replications.. Following are the objectives of the experiment- To study the Physico-chemical properties of soils of the site in relation to growth of the seedlings, Traits association analysis of Edaphic factors with growth, yield and survival of seedlings and To study the survival and growth of seedlings. Following parameters were measured during the experiment, growth parameter- Height (cm), Diameter (cm), Basal Area (m2), Volume, Crown width (m3), Number of branches, Survival of seedling (%) and Soil parameters- Soil moisture, Soil texture, Soil Organic Carbon, Soil pH, Soil available Nitrogen, Soil available Phosphorus, soil available Potassium. The results for the soil parameters are, moisture percentage of the soil is 15.59%, Soil texture is sandy loam, soil organic carbon is 0.198, pH is 4.64, Soil available Nitrogen 211.23, Soil available Phosphorus is 14.07 and soil available Potassium is 166.43. Above soil conditions influenced the growth and yield of seedlings species in the following manners, Maximum height among the different seedling species of Bhusur, Ormanjhi was found under treatment T2 Acacia auriculiformis (2.30 m) and it was at par with T1 Cassia siamea (1.85 m), T3 Melia azedarach (1.73 m) and least was found under treatment T4 Tectona grandis. The maximum number of branches was found in case of treatment T2, Acasia auriculiformis (15.82) followed by T1, Cassia siamea (13.27), T3 Melia azedarach (3.24) which was at par with the least value which was treatment T4 Tectona grandis (1.77). The maximum value of girth was found in case of treatment T2 Acasia auriculiformis (2.32 cm) which was at par with treatment T1 Cassia siamea (2.13 cm) followed by T3 Melia Azedarach (0.66 cm) which was at par with the treatment T4 Tectona grandis (0.62 cm) which was having least value. The maximum value of diameter was found in T2 Acacia auriculiformis (0.74 cm) which was at par with the treatment T1 Cassia siamea (0.68 cm), Melia azedarach (0.21 cm), and minimum was found in T4 Tectona grandis (0.2 cm).The maximum crown spread was found in case of treatment T1 Cassia siamea (1.93 m) followed by T2 Acacia auriculiformis (1.69 m), T3 Melia azedarach (0.95 m) and minimum was found in T4 Tectona grandis (0.31 m). Significantly highest basal area was found in case of T2 Acacia auriculiformis (0.22 ) followed by T3 Melia azedarach (0.09 ) which was at par with the treatment T1 Cassia siamea (0.07 ) and least was found in case of treatment T4 Tectona grandis (0.05 ). In case of volume, Significant highest volume ( ) was found in case of Acacia auriculiformis (0.50 ). Followed by Cassia siamea (0.29 ), Melia azedarach (0.07 ) and it was at par with the treatment, tectona grandis (0.04 ). And The maximum survival percentage among different seedling species of Bhusur Ormanjhi was found under treatment T1 Cassia Siamea (73.39 %) and it was at per with the treatment T2 Acacia auriculiformis (72.39 %), T3 Melia azedarach 964.05 %) and least was found under treatment T4 Tectona grandis (47.00 %). In case of plant height, diameter, girth, and number of branches among four species, Acacia auriculiformis showed the maximum growth and Cassia siamea showed the maximum crown spread. In case of basal area and volume Acacia auriculiformis has showed more basal area and volume. Cassia siamea has showed the maximum survival %, followed by Acacia auriculiformis, Melia azedarach and least is Tectona grandis. The soil of the site is sandy loam which suits Acasia auriculiformis to grow better than Cassia siamea, Melia azedarach and Tectona grandis. In respect to all the growth parameters Tectona grandis showed the least growth as well as survival percentage.
