Effect on yield and net returns of pea+maize intercropping on raised bed with weed management.

摘要

An experiment was carried out during 2007-08 and 2008-09 to study the effect on inter yield and net returns of pea+maize on raised bed with weed management practices in winter season in KVK, Jamui (Bihar) operational area. The experimental area was sandy loam in texture with pH 7.5, medium in available nitrogen, phosphorus and potassium. Three treatments consisted of intercropping and five treatments consisted of weed management practices on pea+maize on raised bed. The maximum maize equivalent yield was found (84.2 q/ha) in intercrops on raised bed, whereas pea and maize sole crop on raised bed was 48.75 and 43.8 q/ha, respectively. Highest weed control efficiency (74.1%) was recorded with atrazine @ 0.5 kg a.i./ha followed by pendimethalin @ 1.00 kg a.i./ha (71%) and lowest under one hand weeding (60%).
