Other claims from this paper (5)

Observation Simulated national maize yields were slightly above the mean reported from 1984 to 2014.
Association Periodic drought delayed maize sowing.
Association Periodic drought reduced maize yield.
Observation The modeled maize production had high risk and low sustainability in most maize areas.
Intervention effect Long maturity, drought tolerant cultivars combined with high fertilizer input could increase national maize production up to fivefold.

Diverse fertility building leys in arable rotations (OK-Net Arable Practice Abstract)

Katie Bliss; Mark Measures Organic Eprints (International Centre for Research in Organic Food Systems, and Research Institute of Organic Agriculture) 2017

Other claims from this paper (12)

Observation Complex mixtures had greater resilience to variable conditions.
Observation Complex mixtures combined early and late weed suppression.
Observation Complex mixtures decomposed more slowly on incorporation.
Observation Complex mixtures extended forage availability for insect pollinators.
Observation Complex mixtures generally achieved higher forage yields.
Association Grass species in the mix reduced free soil nitrogen.
Association Low soil nitrogen was associated with higher nitrogen fixation by rhizobia.
Association Low soil nitrogen was associated with greater biomass.
Association Higher carbon-to-nitrogen ratio prolonged nitrogen release to later crops.
Observation Annual nitrogen accumulation of ley mixtures decreased after two years.
Observation Including a third or fourth legume was generally advantageous for forage yield.
Recommendation The best multifunctional mixtures contained Black Medic, Lucerne or Red Clover with other legumes.
