Other claims from this paper (10)

Intervention effect Sunflower monoculture gave the highest sunflower grain yield, 275 g m-2
Intervention effect Soybean monoculture gave the highest soybean grain yield, 130.1 g m-2
Intervention effect The 100:50 additive intercropping ratio gave the lowest soybean grain yield, 48.5 g m-2
Intervention effect Intercropping ratio of 25:75 gave the highest land equivalent ratio, monetary advantage index and intercropping advantage value
Association Sunflower had higher aggressivity and crowding ratio values than soybean in all cropping patterns
Observation The highest density of herbivores was recorded in soybean monoculture
Observation Thripidae had the most relative density among insects in the sunflower and soybean system
Observation Cicadellidae had the most relative density among insects in the sunflower and soybean system
Intervention effect Intercropping sunflower with soybean increased the abundance of pollinators and natural enemies compared with monocultures
Recommendation Intercropping sunflower with soybean at 25:75 is a feasible alternative to monocropping for similar production
