Corn (Zea mays L.) green matter production in different sowing densities

Abstract

Objective: To evaluate the corn green matter production at different sowing densities, in Valle del Mezquital, Hidalgo, Mexico. Design/Methodology/Approach: The DK-4018 hybrid corn was sown in the spring-summer 2021 cycle. The treatments (T) were different sowing densities: (T1) 112,500, (T2) 120,000, and (T3) 136,000 plants per hectare. The experimental design was completely randomized. The evaluated variables were: plant height at 30, 60, and 76 days after sowing (cm); final stem diameter at ground level (cm); fresh weight (g); and green matter yield (ton ha-1). The results were analyzed with the SAS program (2001) and the means were compared with the Tukey test (p ≤ 0.05). Results: The highest green matter production of the DK-4018 hybrid corn was obtained with a sowing density of 136,000 plants per hectare, with an estimated yield of 114.6 ton. Study limitations/implications: No scientific publications about the DK-4018 hybrid corn green matter production were found. Findings/Conclusions: With a population density of 136,000 corn plants per hectare, 114.6 ton of DK-4018 corn green matter yield is estimated.

“…The corn plant (Zea mays L.) is native to Mexico and Central America and has adapted to various edaphoclimatic conditions (Osorio-Santiago et al, 2022). Its uses are diverse, including as food, fodder, feed, and fuel, making it a standout and a high-value crop (Aakash et al, 2022).…”
