Abstract: Four types of spacing viz. 2.5 x 5cm (B1), 5 x 5cm (B2), 10 x 5cm (B3) and 10 x 10cm (B4) along with fertilizer viz. control (F0), 50 kg N ha-1 (F1), 100 kg N ha-1 (F2), 150 kg N ha-1 (F3), N50+1.0 t FYM ha-1 (F4), N50+1.5 t FYM ha-1 (F5), N100 + 1.0 t FYM ha-1 (F6) and N100 + 1.5 t FYM ha-1 (F7) were used to assess their effect on survival and growth parameters of seedlings. This experiment was laid out in factorial randomized block design with three replications each. All the seedling growth parameters increased with the increase in spacing except plant height which was found maximum (22.27cm) at narrow spacing (2.5 x 5cm). All other growth parameters viz. collar diameter (2.29 mm), root dry weight (0.30 g), shoot dry weight (0.63 g), shoot root ratio (2.13), total fresh biomass (2.53 g) and plant per cent (66.54%) were found maximum in seedlings at wider spacing (10 x 10 cm) and minimum values in these growth attributes were recorded in narrow spacing (2.5 x 5cm).The nitrogen fertilizer along with farm yard manure showed significant effect on seedling morphological characters. The maximum plant per cent (67.10), plant height (23.53cm), collar diameter (2.40 mm), dry root weight (0.35 g), dry shoot weight (0.74 g), shoot root ratio (2.16) and total fresh biomass (2.87 g) were recorded in seedlings supplied with N50+1.5 t FYM ha-1 (F5). The minimum values in all these parameters were recorded under control conditions. Under open nursery beds, the seedlings of Pinus halepensis on application of N50+1.5 t FYM ha-1 in two equal splits (half at transplanting and another half after 30 days of transplanting) with 10 x 10 cm spacing is found to be the most promising treatment combination for producing more biomass per plant and healthy nursery stock.
