Description The present investigation entitled “Effect of various spatial arrangements of Populus deltoides
on growth and yield of wheat varieties” was carriedout at research area of Forestry Department, CCS
Haryana Agricultural University, Hisar during winter seasons of 2013-14 and 2014-15 to study the
effect of different spatial arrangements(5 × 4 m, 10 × 2 m and paired row 18 × 2 × 2 m) and different
row directions (East-West and North-South) after completing 7 years and 8 years of age of poplar on
the performance of different wheat varieties (HD-2967, WH-542, DPW-621-50, HD-943 and WH-1105). Production of various wheat varieties was significantly reduced in association with all the three
spatial arrangements of poplar in comparison to control. Paired row planting (18 × 2 × 2 m) of poplar
was found best for production of wheat followed by 10 × 2 m and 5 × 4 m. Among wheat varieties,
variety HD-2967 produced significantly higher number of total tillers, effective tillers, number of
spikes, spike length, number of grains/spike, test weight, grain and straw yield in paired row (18 × 2×
2 m) planting than planting at 10 × 2 m and 5 × 4 mduring 2013-14 and 2014-15. The variety WH-1105 was found to be very sensitive to shade and exhibited very poor growth, yield attributing
characters and yield under different spatial arrangements of poplar however, it showed highest growth
and yield under control. Growth of poplar was significantly higher in 5 × 4 m planting than 10 × 2 m
and paired row planting (18 × 2 × 2 m). The organiccarbon in soil increased with the decrease in tree
spacing and was maximum (0.74%) under 5 × 4 m spacing and which had followed the order of 5 × 4
m >10 × 2 m >18 × 2 × 2 m > control after the harvesting of wheat crop during 2014-15. On the other
hand, in different row directions of bund planted poplar after the harvest of wheat crop, the organic
carbon was found significantly higher up to 2 m distance from poplar tree line during 2014-15. The
available nitrogen, phosphorus and potassium were also significantly influenced by row directions of
bund planted poplar as in organic carbon. The significant differences in total tillers, effective tillers,
number of spikes, spike length, number of grains/spike, test weight, grain and straw yield were also
observed in all the four aspects during both the years. Among different wheat varieties, HD-2967
recorded maximum number of spikes, spike length, number of grains/spike, test weight, grain and
straw yield in southern aspect, at all the distances (2, 4, 6, 8 and 10 m) from tree line followed by
variety WH-542 and DPW-621-50 during 2013-14 and 2014-15.The reduction in wheat production was
maximum in northern aspect followed by eastern and western aspect. The variety WH-1105 exhibited
lesser number of growth and yield attributing parameters in all the four aspects of East-West and
North-South poplar bund plantation however, it showed higher number of growth and yield attributing
parameters in control during both the years under the study.
