Evaluation of Bio Dynamic Compost and Bio Dynamic Compost Wash on Growth and Yield of Rice

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.
