Relationship of trunk cross-sectional area with growth, yield, quality and leaf nutrient status in Kinnow mandarin

An experiment was on five-year-old Kinnow trees, planted at a spacing of 6 m × 6 during the year 2008–10. Plants receiving uniform management practices were selected during September and classified into five different trunk cross-sectional area groups. The canopy volume, leaf area, yield and production efficiency increased gradually with the increase in trunk cross-sectional area. The maximum canopy volume (10.34 m³) was recorded at the highest trunk cross-sectional area (97.45 cm²). A positive and significant correlation was observed between TCSA and fruit yield (+0.953) and TSS (+0.872).
