Variety and weed management effects on organic chickpea stand establishment and seed yield
Abstract The need for organic produce is increasing worldwide but weed control remains a critical problem for organic crop production. Three types of weed control practices were evaluated for two organic chickpea (Cicer arietinum L.) varieties at the Western (Corvallis) and Eastern (Sidney) Agricult...

Three types of weed control practices were evaluated for two organic chickpea (Cicer arietinum L.) varieties at the Western (Corvallis) and Eastern (Sidney) Agricultural Research Centers of Montana State University. Treatments included two chickpea varieties (Black and CDC Orion chickpeas), two seeding rates (standard seeding rate or 1× at 43 seeds m−2 and 50% increase over the standard rate or 1.5×), and two pre‐emergent weed control practices (flame weeding and shallow tillage). Results revealed that Black chickpea was associated with greater stand densities and grain yield with lower weed biomass than CDC Orion. Increasing seeding rate for Black chickpea improved crop density and increased grain yield to the extent of 26% compared with the standard seed rate. Flaming increased chickpea grain yield only at Corvallis in 2016. The combined effects of shallow tillage and increased seeding rates resulted in reduced weed biomass. Shallow tillage can be successfully integrated to improve yields and reduce weed pressure in organic chickpea. However, precaution must be taken for the tillage timing to avoid damage to emerging chickpea seedlings. More research is needed to select chickpea varieties that have improved vigor and are more competitive to weed pressure commonly seen in organically managed fields.https://doi.org/10.1002/agg2.20035 |
