Effects of planting method on agronomic characteristics, yield and yield components of sweet and super sweet corn (Zea mays L.) varieties under saline conditions

In order to evaluate the effects of planting pattern on morphological, Phonological, yield and yield components of sweet and super sweet corn (Zea mays L.) varieties under saline conditions, a field experiment was conducted as split plots based on a randomized complete block design with four replications. Planting pattern in 3 levels included one row in ridge, two row in ridge and furrow planting, as a main plot and varieties in 4 levels sweet corn with 2 types (KSc 403 su, Merit) and super sweet with two types (Basin, obsession) as sub plots. The results showed that planting pattern had significant differences on plant height, ear height, leaf length, leaf width, number of kernel per row, number of rows per ear and 1000-kernel weight. but had no significant effects on the length of tassel, number of leaf/plant, number of leaf per plant above ear, stem diameter, time of anthesis, time of silking, anthesis silking interval) ASI), grain yield, biological yield and harvest index. Different varieties had significant effects on the total characteristics studied except number of leaf above ear and stem diameter. Most of the conservable grain yield and harvest index was in Obsession variety (10 kg and 39%, respectively) and the least was seen in Basin (4 kg and 20%, respectively). The result showed that use of furrow planting pattern for sweet and super sweet corn in saline conditions can effects result in higher yield.
