The researchers studied how different levels of nitrogen and spacing between plants affect the growth and yield of sweetcorn. They tested three nitrogen levels (80, 100, and 120 kg/ha) and three spacing configurations (75x10 cm2, 60x20 cm2, and 45x30 cm2) in a field experiment. The results showed that using 120 kg/ha of nitrogen with a spacing of 60x20 cm2 led to taller plants, more cobs per plant, higher green cob yield, and better financial returns compared to other treatments. This combination also resulted in a higher harvest index, indicating efficient resource use.
