Correlational Analysis between Growth and Yield Parameters of Cabbage (Brassica oleracea) as Affected by Organic Manure and Inorganic Fertilizer in Jos

Aim: To determine the correlation between the growth and yield parameters of cabbage grown with organic manure and inorganic fertilizer.

Study Design: The experimental design consist of randomized complete block design with five treatments which were replicated four times.

Location and Duration: The experiment was conducted at the experimental field of Federal College of Forestry, Jos, during the 2018/2019 raining season.

Methods: Land clearing was done and the land was properly demarcated based on the different treatments and replicates. Cabbage seeds were first planted in a nursery bed and later transplanted onto the experimental plots. Data was taken on the plant height, leaf count, cabbage head diameter and head weight. The data collected were subjected to analysis of variance (ANOVA) using SPSS version 23 and Duncan Multiple Range Test, used to separate the means were significance occurred.

Results: The result of the correlation coefficient of growth and yield showed that a strong correlation exist between plant height and cabbage head weight (r = 0.681 and 0.648) at P ≤ 0.01. Plant height was also positively correlated with head weight (r = 0.365, P ≤ 0.05) and head weight was as well and positively correlated with head diameter at (r = 0.501, P ≤ 0.05).

Conclusion: Based on the results obtained, it can be concluded that application of organic manure and inorganic fertilizer has positive correlations between the growth and the yield parameters of cabbage.
