Influence of Fertilization and Spacing on Growth and Nutrient Uptake in Poplar (Populus deltoides) Nursery

An experiment was conducted to determine the effect of four fertilizer levels (NoPoKo, N100P56K25, N200P1ooK50 and N4OOP2ooK1OO kg ha.1), and three spacings (35 cm x 35 cm, 50 cm x 50 cm and 65 cm x 65 cm) on growth parameters, biomass production and uptake of nutrients by PopUlus deltoides in nursery. Fertilizer application increased significantly the collar diameter, height, shoot biomass and nutrient uptake. Wider spacing (65 cm x 65 cm) produced plants having significantly higher biomass and growth parameters. The uptake of nutrients was significantly higher at closer spacing of 35 cm x 35 cm than at wider spacing (65 cm x 65 cm) but uptake per plant was lower.

Abstract


An experiment was conducted to determine the effect of four fertilizer levels (NoPoKo, N100P56K25, N200P1ooK50 and N4OOP2ooK1OO kg ha.1), and three spacings (35 cm x 35 cm, 50 cm x 50 cm and 65 cm x 65 cm) on growth parameters, biomass production and uptake of nutrients by PopUlus deltoides in nursery. Fertilizer application increased significantly the collar diameter, height, shoot biomass and nutrient uptake. Wider spacing (65 cm x 65 cm) produced plants having significantly higher biomass and growth parameters. The uptake of nutrients was significantly higher at closer spacing of 35 cm x 35 cm than at wider spacing (65 cm x 65 cm) but uptake per plant was lower.
