Other claims from this paper (14)

Intervention effect AS1 intercropping achieved a land equivalent ratio above 1 for fresh and dry biomass, compared with sole crop controls.
Intervention effect AS1 intercropping reduced millet yield compared with sole crop controls.
Observation Sole soybean had the highest P concentration in its vegetative and reproductive parts.
Intervention effect AS1 increased B and Zn accumulation in the vegetative part of biomass, compared with sole crop controls.
Intervention effect AS1 intercropping gave only a minimal reduction in P in the vegetative part of biomass.
Intervention effect AS1 intercropping had no significant change in Fe concentration compared with sole crop controls.
Intervention effect Alternating rows (AR) significantly increased P accumulation in the reproductive part of millet, compared with sole crop controls.
Intervention effect All intercrop combinations reduced B concentration in millet, compared with sole crop controls.
Intervention effect AS1 intercropping improved Fe level in both parts of millet biomass, compared with sole crop controls.
Association Zn accumulation and translocation in millet differed with planting pattern.
Intervention effect The biofertilizer Coveron positively influenced P accumulation in soybean pods.
Intervention effect The biofertilizer Coveron positively influenced B in millet panicle.
Intervention effect The biofertilizer Coveron negatively affected P and Zn accumulation in the vegetative part of millet.
Recommendation The authors recommend alternating two-row soybean-common millet strips for enhancing land use efficiency and nutrient accumulation in forage biomass.

Other claims from this paper (11)

Association LER depends on the relative densities of two crops.
Method / resource LER fails to indicate the optimal density combination for maximum productivity.
Association Maize monocrop yield had an asymptotic relation with density.
Association Bean monocrop yield had an asymptotic relation with density.
Intervention effect Adding a second crop had no effect on maize yield.
Intervention effect Adding a second crop greatly reduced bean yield.
Observation No LER value differed significantly from unity.
Association Highest LER values occurred in high density maize plots.
Method / resource The reciprocal model explained up to 90% of observed intercrop yields.
Observation A planting density of 11 maize and 39 bean plants per square metre maximized yield advantage in the tested range.
Observation Authors consider the maximum productivity combination unlikely to maximize gross economic margin.
