2.8 Statistical Analysis
The least significant difference (LSD) was executed along with one-way analysis of variance (ANOVA) with four replications in randomized complete block design (RCBD) to determine mean differences between different treatments for plant and soil variables, besides runoff and soil loss. The R studio (Version 3.5.1) software was used for statistical analysis. The statistical significance was determined and compared using Duncan multiple range test at a significance level of P < 0.05 (Gomez & Gomez, 1984). To demonstrate relationship between different parameters and their interaction with various treatments, we utilized above software to conduct principal component analysis (PCA) and correlation matrix.
