Effect of different levels of organic fertilizers and inorganic Fertilizers on growth and yield of barely (Hordeum vulgare) under Poplar (Populus deltoids) based agroforestry system

A field experiment which was carried out in the nursery of College of Forestry, SHUATS, Prayagraj 2019 - 2020 to evaluate effect of the different levels of Organic and Inorganic fertilizers on growth and yield of Barely (hordiumvulgare) under poplar based agroforestry system. Field was prepared, plot was divided into 33 blocks and 11 treatments were given and replication of each treatment was three, then seeds of Barley were line sown and mild irrigation was given to field. There were eleven treatments viz., T0 (controlled); T1 (recommended doses of NPK); T2 (compost); T3 (FYM); T4 (Vermicompost)., T5 (Vermicompost 50% + Compost 50%), T6 (Vermivompost50% + FYM50%), T7 (Vermicompost 33% + Compost 33% + FYM33%), T8 (Vermicompost50% + Recommended NPK), T9 (Compost50%+ Recommended NPK), T10 (FYM 50% + Recommended NPK). Experiment was laid out in the Randomized Block Design (RBD) with three replications. The study also revealed that application of T8 (NPK 50% + Vermicompost 50%) was found to be the best treatment for obtaining the maximum plant height (95.66 cm), no. of tillers hill-1 (11.20), length of spike (16.32 cm),no. of grains spike-1 (55.63)test weight (47.16g), grain yield (37.80 q ha-1) and straw yield (47.63 q ha-1) of Barley. As for the economic yield of barley cultivation study revealed that the results application of T9 (NPK50% +Compost50%) was found to be the best treatment for obtaining benefit cost ratio (1: 2.08) of Barley.
