Abstract

ABSTRACT


Objective: The objective of this research was to evaluate the green matter production of corn at different planting densities, in the Mezquital Valley, Hidalgo, Mexico.


Design / methodology / approach: In the spring-summer cycle of 2021, the corn hybrid DK-4018 was sown. The treatments (T) were different planting densities, (T1) 112,500, (T2) 120,000 and (T3) 136,000 plants per hectare. The experimental design was completely random, the variables were plant height at 30, 60 and 76 days after sowing (cm), final stem diameter at ground level (cm), green plant weight (cm) and material yield. fresh (t ha-1). The results were analyzed with the SAS program (2001) and the comparison of means with the Tukey test (P<0.05).


Results: The best maize sowing density for the production of green matter with the DK-4018 hybrid was obtained with 136,000 plants per hectare and an estimated yield of 114.6 ton.


Limitations of the study / implications: In the literature review it was found that there are no published works on this variety of corn for the production of green matter.


Findings / conclusions: It is concluded that, with a population density of 136,000 corn plants per hectare, a yield of 114.6 ton of DK-4018 corn green matter is estimated.


Keywords: production, fresh weight, plant height, Valle del Mezquital.
