Second Crop of Corn Cultivation and Soybean Agricultural Evaluation of Characters and Their Relationships

Abstract

This research was carried out in the summer season of 1990-1991 vegetation in order to determine the most suitable sowing rates of corn and soybean to be grown in Cukurova ecological conditions. In the trial; LG 55 medium late hybrid corn and SA 88 soybean were used as materials. Sowing ratios subject to the experiment are 1 Corn (10,15,20 cm) + 1 Soybean (2.5 and 5.0 cm) and 2 Corn (10,15,20 cm) + 2 Soybean together with pure corn (70cmx20cm) and soybean parcels (35cmx5.0cm). (2.5 and 5.0 cm) mixture threads were included. Accordingly, each block consists of 14 plots and four repetitive random blocks were run according to the trial pattern. In the co-cultivated corn, there is a significant and positive relationship between plant height, first cob height and crude protein yield, and a negative significant relationship between peak tassel emergence and the number of days of ripening. In the co-cultivated soybean significant and positive relationship between the number of branches in the soybean and the number of beans, important and positive relationship between grain yield and crude protein yield and there was a significant and negative relationship between 50% of the number of days of flowering of the same character. Findings obtained showed that in co-cultivation system studies, plant height in corn, the height of the first cob, number of branches in soybean, number of broad beans, and number of seeds in broad beans have vegetative features that should be emphasized.
