Abstract
Optimal tree spacing not only enhances yield but also boosts carbon
sequestration, a key factor in combating climate change. To optimize tree
spacing and assess biomass accretion patterns, a
study was conducted to assess the growth and biomass parameters of Grewia
optiva trees within an existing agroforestry system under three different tree
spacings: S1 (8 × 1 m), S2 (8 × 2 m), and S3
(8 × 3 m) in the mid-hills of Himachal Pradesh during the years 2021-2022 and
2022-2023. The results revealed significant variation under different tree
spacings (S1 to S3). Growth and biomass parameters values
of tree height (6.34 m), diameter at breast height (16.32 cm), crown spread
(2.30 m), number of branches (4.82), fodder yield (6.92 kg tree-1),
torchwood yield (5.65 kg ha-1), and bast fiber (750 g tree-1)
were maximum under spacing S3 and minimum under S1. Leaf
Area Index (LAI) was maximum (1.22) in spacing S1, and
photosynthetic active radiation (PAR) in the understorey was maximum (433 µmol
m-2s-1) in spacing S3. Therefore, trees spaced
at spacing S3 (8 × 3 m), which exhibited the highest growth parameters,
can be recommended for different agroforestry models in the mid-hills of
Himachal Pradesh.
