Intervention effect Plant height of lentil and field pea was similar in sole crops and intercrops.
Intervention effect Faba bean and chickpea were stunted in some intercrop treatments.
Intervention effect Intercropping reduced lodging of lentil and field pea in 2016 and 2017.
Intervention effect Seed yield and LER of faba bean and chickpea in intercrops were similar or noticeably lower than sole crops.
Intervention effect The 2015 intercrops gave very little gain in total seed yield and total LER because of very dry weather.
Intervention effect With adequate rain in 2016 and 2017, lentil intercrops gave greater total seed yield and total LER than sole crops.
Intervention effect Gains in total seed yield and total LER from field pea intercrops over sole field pea were small and not consistent.
Association Intercropping lentil with faba bean and chickpea shows potential for improving seed yield and total LER over sole lentil.
Observation Plant counts of lentil and field pea sole crops were similar or slightly lower than the intercrop seeding rates.
Observation Plant counts of faba bean and chickpea sole crops were similar or lower than the intercrop seeding rates.
