| dc.description.abstract | The application of fertilizers in agriculture crops has been widely practiced since many years, but its application in forestry plantation is of a recent origin. The usefulness of fertilizers in the forest nurseries for production of healthy planting stock usually will be of much use in getting established the plantation. Keeping this view in mind an experiment entitled "Influence of nitrogenous, phosphatic and potassic fertilizers on production of healthy seedlings of Albizia lebbek (L.) Benth. in nursery" was conducted at the nursery of Faculty of Forestry, Birsa Agricultural University. Ranchi. Kala Siris [Albizia lebbek (L.)Benth.] is a leguminous multipurpose tree, produces nitrogen rich fodder, green manure, high quality fuel and timber, medicine and host tree for lac. Three type of fertilizers viz, Urea, Single Superphosphate and Muriate of Potash were used either singly or in combination. There were 15 treatments with three replications, arranged in completely randomized design. All treatments of SSP and MOP were applied as basal dose at the time of tube filling and simultaneous seed sowing, however Urea was applied as one basal. dose and two equal split doses at 15 days interval. Various parameter such as seedling height, collar diameter, root length, number of root nodules, number of branches, leaf number, leaflet area, fresh weight, dry weight and survival were taken from the end of second month upto the seventh month. At the end of seven month maximum seedling height was observed in N100 (20.40 cm) followed by N100P 100Kso (19.70 cm). Similarly in the case of collar diameter, maximum value was obtained by N100 and minimum value is noticed in K treatment. A significant difference in root length of seedlings was found for all the treatments with the maximum value in N100P100Kso (32.36 cm) followed by K75 (31.43 cm) and minimum value in Kas (24.68 cm) treatment. In the case of root-shoot ratio, maximum effect was noticed in combined dose of Psokso which was at par with control (2.11). The formation of root nodules was more actively noticed between the age of 3 to 5 month, which decreases afterwards. Treatments like N100 K75,P50K50 were at par with control in formation of root nodules. | |
