Response of three waxy corn (Zea mays L. var. ceratina kulesh) varieties and various planting date of intercropped groundnut (arachis hypogaea L.) in dry field

Abstract

The research aims to determine the combination of waxy corn variety and planting date on the growth and yield of waxy corn in an intercropping system of corn and groundnut (Arachis hypogaea L.). The experimental design is a split-plot with the main plot consisting of waxy corn varieties (local variety; Uri variety and Binte Pulu variety and the sub-plot consisting of the alternate crop planting date. Three replications are performed. Data collection is done destructively. The F test at 5% is used to examine the effect of treatments, while differences across treatments are based on the LSD at 5%. Research results show an interaction between the waxy corn variety and planting date on the growth parameter. There is an improved yield from the local variety planted 15 days before the groundnut planting date, as well as from the Uri variety planted both simultaneously with, and also 15 days before, the groundnut planting date, with maximum yields of 2.99, 2.75 and 2.69 ton ha-¹, respectively.
