Substitution of Nitrogen and Phosphorous by Bio-Inoculants and Their Effect on Growth Parameters, Yield Attributes and Yield of Barley

Abstract

A field experiment was conducted during Rabi season of 2022-2023 at Rajoula Agriculture farm, of Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya Chitrakoot, Satna (M.P.). The present experiment having 13 treatment combinations replicated thrice in randomized block design. Barley variety HUV-113 was grown with recommended agronomic practices. On the basis of the results emanated from present investigation, it could be concluded that application of T11 [100 % N & P + PSB + Azotobacter + 100 % K] significantly recorded maximum growth parameters of barley such as plant population plot-1 (41.56 m-2), plant height (91.78 cm), and number of tillers (87.74) and maximum yield attributing characters such as no. of spike (73.38 m-2), spike weight plant-1 (51.20), number of spikelet (256.19) and test weight (45.76 g). Similarly highest grain yield (40.19 q ha-1) and straw yield (62.71 q ha-1), with application of treatment T11 [100 % N & P + PSB + Azotobacter + 100 % K] in comparison to all the treatments. While minimum value of all the growth parameters, yield components and yield were associated with the treatment T1 [Control].
