Abstract
The present investigation, was conducted in the Kharif of 2021–2022 at the Student's Instructional Farm at the A.N.D. University of Agriculture & Technology, Kumarganj, Ayodhya (U.P.). The experiment was laid out in Randomized Block Design, replicated thrice, having 8 treatments i.e. T1 (Absolute Control), T2 (Bio dynamic compost 1q/ha + 50 % RDF), T3 (Bio dynamic compost 2 q/ha + 50 % RDF), T4 (T2 + Root dipping with Bio dynamic compost wash 10 ml/ lit of water), T5 (T3 + Root dipping with Bio dynamic wash 10 ml/lit of water), T6 (T2 + foliar application of Bio dynamic compost wash of 10 ml/10 lit of water), T7 (T3 +foliar application of Bio dynamic compost wash of 10 ml/ lit of water), T8 (100 % RDF. Result revealed that the highest growth attributes viz., Plant height (cm), maximum dry matter accumulation, highest number of tiller (m-2), Panicle length (cm), number of grain per panicle and test weight (gm), maximum grain yield (q ha-1), highest straw yield, maximum biological yield (q ha-1) and maximum harvest index (q ha-1) was recorded significantly over rest of the treatments in T7 (T3 +foliar application of Bio dynamic compost wash of 10 ml/ lit of water) while it recorded lowest in in T1 (absolute control) during the investigation.
