The researchers studied how growing winter maize with other crops like potato and pea affects its growth and yield. They found that intercropping maize with potato resulted in the highest plant height and dry matter accumulation. Maize + potato intercropping gave the highest grain yield compared to growing maize alone. The study showed that the stems and cobs of maize contributed the most to its total dry matter production. Intercropping maize with toria and wheat led to a decrease in total dry matter production. Overall, intercropping maize with certain crops can increase its yield by improving biomass production and maximizing the partitioning of dry matter into cobs.
