| Summary: | The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agroecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and
yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain
yield was 17% under one year old poplar plantation, which increased to 52.15% under five year old
plantation. The values of micro-meteorological parameters (light intensity and air temperature) were also
low under plantations than in open condition and decreased with increase in plantation age. The current
and mean annual increments in biomass and carbon storage curves exhibited a sharp increase of up to
three years which thereafter increased with decreasing order. The carbon storage in the poplar biomass
was estimated to be 34.075t/ha at the age of five years, which can be fixed as the maximum volume
production rotation of this species under the prevailing conditions. |
