Intercropping with optimal nutrient management increased sweet corn yield by 13% to 15.6%.
Planting sweet corn and cowpea in a 2:2 row pattern significantly enhanced growth and yield metrics.
Nutrient management using 75% of soil test based recommended fertilizer led to higher sugar and protein content in sweet corn.
Findings highlight sustainable intercropping practices, benefiting both yield and economic viability for farmers.
