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

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].

Electromagnetic field in and around the campus of Jawaharlal Nehru University, New Delhi.

We have surveyed the levels of magnetic field in the open environment around the high-tension lines as well as in the domestic and laboratory environment in the JNU campus. Measurements were made in the direction of most likely access, and from the surface of the appliances. The data so obtained are analyzed and compared with some quoted in the literature. It is hoped that the results will be useful for epidemiological studies in determining the criteria for safe human exposure.
