dc.description.abstractThe present investigation entitled “Performance of different barley varieties under Populus deltoides based agroforestry system” was carried out at the research area of Department of Forestry, CCS Haryana Agricultural University, Hisar during 2019-20. The performance of five barley varieties (BH 946, BH 959, BH 393, BH 885 and BH 902) grown under poplar plantation and as sole crop were examined to ascertain the effect of environment on growth, physiology, yield attributes and yield. The various growth, physiological and yield attributing parameters of different barley varieties were observed significantly higher in sole barely crop (devoid of trees) than under poplar plantation except chlorophyll content, relative water content, relative stress injury, canopy temperature depression. The plant population/m2 , number of effective tillers/m2 and test weight of variety BH 885 was maximum, however yield of BH 885 was lesser than other barley varieties (BH 946, BH 393 and BH 902). A significant reduction was observed in yield of different barley varieties under poplar plantation. The maximum reduction of 23.39 % was observed in variety BH 959 followed by BH 885 (21.34 %), BH 902 (18.26 %), BH 393 (16.33 %), and it was minimum in variety BH 946 (15.19 %). The B:C ratio was maximum in BH 946 (1.22) followed by BH 393 (1.12), BH 902 (1.11), BH 885 (0.96) and minimum in BH 959 (0.89) under poplar plantation. Soil pH and EC were decreased more significantly under poplar plantation than sole barley crop. A significant increase in soil organic carbon, available N, P, K and DTPA extractable micronutrients (Zn, Cu, Mn and Fe) was observed at all depths (0-15, 15- 30 and 30-45 cm) under poplar plantation than sole crop. The total N, P K and micronutrients uptake was observed maximum in variety BH 946 and minimum in BH 959. The moisture content was observed higher under poplar plantation than sole crop at all the soil depths. Furthermore, the soil moisture content increased along with an increase in distance from the tree line. The average per cent reduction in light available to understory crops was maximum in November (60.22%) and minimum in February (35.62%). The temperature was observed slightly lesser under poplar plantation than open environment (devoid of trees), however a reverse pattern was observed in case of relative humidity.en_US
