Abstract
The present investigation entitled “Performance of barley varieties under Melia dubia Cav. based agroforestry system” was carried out at a farmer field in village Gillan Khera of district Fatehabad situated in western semi-arid region of Haryana during Rabi season of 2018-2019. The experiment was carried out to study the performance of five barley varieties (BH-902, BH-959, BH-885, BH-946 and BH-393) under Melia dubia along with growth of trees, moisture and changes in chemical properties of soil. The mean of various tree growth parameters viz. diameter at breast height (55.95 cm), tree height (15.70 m), and canopy spread (6.31 m) was recorded higher in intercropped trees compared to pure stand of Melia dubia. Plant growth parameters and yield attributes were reported significantly higher in open conditions as compared to under plantation. Different growth parameters viz. number of tillers, number of spikes, test weight were found higher in BH-885. Maximum grain yield was obtained in barley variety BH-946. Plant height at different stages of growth, number of plants per meter, spike length, biological and straw yield was observed significantly higher in BH-902. Barley variety BH-885 was recorded with lesser yield among both the conditions however, it had maximum number of tillers per meter, number of spikes per meter and significantly higher test weight. The soil pH and EC decreased more under plantation of Melia dubia plantation over control (sole barley). A considerable increase in soil organic carbon and available N, P and K content was also observed under Melia dubia based agroforestry system than under control (devoid of trees).A significant increase in soil moisture content was observed while going deeper in soil depth and vice versa while going away from tree row. Physiological parameters viz. photosynthetic rate, stomatal conductance and transpiration were found higher in open conditions whereas RWC and MSI were recorded higher in intercropped conditions.
