Abstract: A field experiment was conducted on Model Organic farm of CSKHPKV, Palampur with 42 treatments of seed bed manipulations and weed management with an objective to study weed management in organically grown wheat during rabi 2015-16. The Interaction effects of seed bed manipulations and weed management methods were found significant on total weed dry weight and wheat equivalent yield. Stale seed bed resulted in significantly lower total weed dry weight over standard seed bed. However, standard seed bed recorded 8.22 per cent higher wheat equivalent over stale seed bed. In stale seed bed, two manual hoeings being at par with gram intercropping + one manual hoeing produced significantly highest wheat equivalent yield as compared to other treatments. Gram intercropping + one manual hoeing being statistically at par with two manual hoeings recorded significantly lower total weed dry weight, higher weed control efficiency and wheat grain equivalent yield.
