Other claims from this paper (5)

Intervention effect Five environmental clusters had significant yield gains of 17–36% as rows narrowed.
Intervention effect Three other clusters had nonsignificant yield increases with narrower rows.
Intervention effect One cluster had virtually no yield change with narrower rows.
Association Yield responded most to row spacing at 100 to 270 mm July and August rainfall.
Recommendation The authors recommend rows at most 40 cm to optimize ESPS yields in the midsouthern USA.

Observation Profitability indicators varied substantially in absolute and relative terms.
Intervention effect Intercropping had a higher 20-year NPV of Tsh 19,238,798.43 versus Tsh 10,934,669.90 for sole maize.
Intervention effect Intercropping had a higher BCR of 4.27 versus 3.59 for sole maize.
Intervention effect Returns to labour per person day were 1.5 times sole maize returns.
Intervention effect A 30% output price decrease reduced intercropping NPV by 38%.
Intervention effect A 30% input price increase decreased sole maize NPV by 11.1%.
Intervention effect A 30% input price increase decreased intercropping NPV by 8.8%.
Intervention effect Equal input price changes had the same relative economic effect on both systems.
Recommendation Intercropping is judged profitable over time and could increase household income and food security.
