Summary

 

The Effects of Planting Time and Spacing on Growth and Yield of Cabbage

in Erzurum Conditions

 

This study was carried out to determine the effects of planting times and

spacing on plant growth and yield in Erzurum conditions. Plants were grown

at the Agricultural Experiment Station No 6 in Erzurum, Turkey. Cabbage

cultivar named Zöhrap locally, was grown in the field conditions.

Three different planting time, May 13, May 23, and June 3; and four different

spacing, 50 by 50 cm, 75 by 50 cm, 75 by 75 and 100 by 75 cm were used.

At the end of the harvest, total yield and percent of heading were determined.

Diameter, height of heads, height of stem; number and weight of open leaves

were determined, too.

Data obtained in this study were analyzed statistically and Duncan's Multiple

Range Test was applied.

The following results were obtained:

1- The highest yield was obtained in the earliest planting with 75 by 75 cm

spacing, and the lowest yield in the last planting with 50 by 50 cm spacing.

2- Low plant density increased head diameter but delayed planting time decreased.

3- The highest and lowest head-heights were obtaineden the first planting with

100 by 75 cm and the last planting with 50 by 50 cm, respectively.

4- Percent of heading increased with decreasing of plant density in the first

planting. The highest percentage of heading in cabbage is obtained in the

last planting time with 75 by 75 cm spacing.

5- The highest and lowest marketable head weights were obtained in the first

planting with 100 by 75 cm and in the last planting with 50 by 50 cm, respectively.

6- The height of stems was greatest in 2 nd planting with 75 by 50 cm.

7- The number and weight of open leaves were highest in 3 rd planting time with 100 by 74 cm spacing.
