Effect of Age and Spacing of Mother Plant Cuttings on Seed Yield

Abstract

Plant height was highly influenced by ages of cutting. The cuttings made and planted from 120 days of mother plants gave highest plant height (1.283 m) which was significantly higher than cuttings of 105 days (1.213 m) and 135 days (1.210 m) of plant age (Table 1). Spacing had no significant influence on plant height although higher spacing (15ʺx5ʺ) gave taller plants than lower spacing (18ʺx4ʺ) of 1.254 m and 1.216 m, respectively (Table 2). Plant height was also affected significantly due to interaction of cutting age and spacing. The highest plant height (1.283 m) was obtained from cuttings of 120 days of mother plants in both the spacing (15ʺx5ʺ and 18ʺx4ʺ) whereas the lowest plant height (1.167 m) was found in 105 days of cutting with spacing 18ʺx4ʺ. Plant height decreased when cuttings planted from other than 120 days plants (Figure 1). These results indicate that effect of cutting age was more dominant than that of spacing on plant height.
