Effect of weed management practices on weeds and yield of wheat under organic conditions of North-West Himalayas

A field experiment was conducted at Model Organic farm of CSKHPKV, Palampur during rabi 2015-16 to assess the impact of seedbed manipulations and weed management methods in organically grown wheat. The results indicated that stale seedbed registered significantly lower density and dry matter accumulation of grassy and broadleaf weeds over standard seedbed. The significantly higher wheat grain yield (2711 kg/ha) was recorded in standard seedbed as compared to stale seedbed (2540 kg/ha). Gram intercropping + one manual hoeing being statistically at par with two manual hoeings recorded lower weed dry matter accumulation and higher weed control efficiency in grassy (73.58%) and broadleaf weeds (80.70%). Two manual hoeings produced significantly higher wheat grain yield (3796 kg/ha) as compared to other treatments.
