Influence of tillage and rotation sequence on corn response and planting pattern

Plain Language Summary Corn ( Zea mays L.), cotton ( Gossypium hirsutum L.), and peanut ( Arachis hypogaea L.) are traditional crops grown in the southeast region of the United States. Row crop producers have adopted many strategies to reduce the presence of disease and parasitic nematodes among peanut. One management strategy that has not been considered is the potential use of twin‐row planting patterns compared to single‐row cropping systems under various tillage practices. The objective of this study is to determine if corn yield differs when comparing twin‐row and single‐row planting patterns when planted in various rotation sequences following corn, cotton, and peanut in continuous strip tillage or conventional tillage. Results indicated that corn yield increased as the length of rotation increased relative to peanut. Furthermore, the increase in the planting of cotton within the rotation also increased corn yield. The use of strip tillage increased corn yield compared to conventional. No significant yield increase was seen when comparing twin‐row to single‐row.
