Certain experiments on nursery techniques for propagation of poplar plants from shoot cuttings.

Cuttings obtained from one year old poplar plants or stool shoots gave better nursery stock than the cuttings obtained from older trees. Longer cuttings (35 cm length) gave better growth as well as survival of plants than smaller cuttings. Thicker cuttings (2.5 cm diameter) proved better than thinner cuttings (1-2 cm diameter). Best time of planting was January and in no case planting of cuttings beyond February is advisable. Of the various a pre-treatments, the soaking of cuttings in water for 12 hours before planting gave better results. Different spacings tried had no significant effect on survival of plants in nursery. The 40 × 60 cm spacing is recommended for best height and diameter growth.
