An investigation was carried
out to ascertain the effect of planting density and nitrogen on the performance
of kaon. The planting density was regulated by the seed rate per hectare. Four
different seed rates (4, 6, 8 and 10 kg ha‾1) and five nitrogen
levels (0, 15, 30, and 60 ka ha‾1) were used for this study.
The result of the study revealed that the planting density significantly influenced
the yield and yield contributing characters such as plant population per square
meter, plant height, number of tiller per plant, effective tiller per plant,
grains per panicles, grain and straw yields. Nitrogen too significantly influenced
the yield and yield contributing characters except plant population per square
meter. The maximum grain yield (1.98 t ha‾1). The dose of 60
kg N ha‾1 produced the highest grain yield (1.87 t ha‾1)
and it was statistically similar to 45 kg N ha‾1 (1.82 ha).
The interaction effect due to seed rates and nitrogen levels showed significant
influence on effective tiller per plant, grain and straw yield and harvest index.
The combination of 10 kg seed and 60 kg nitrogen per hectare produced the highest
grain yield (2.15 t ha‾1). |

The growth and yield potential of nine selected genotypes of sweet potato was studied. Length and weight of vines per plant, number of main stems per plant, number and weight of tubers per plant and weight, length, diameter and dry matter content of tuber varied significantly among the genotypes. The genotypes SP3 gave the highest yield 47.59 t ha -1 followed by SP4 (42.82 t ha -1), SP16 (36.15 t ha -1) and SP1 (35.89 t ha -1). Tuber yield had significant and positive correlation with length and weight of vines per plant, number and weight of tubers per plant, average weight of tuber and diameter of tuber. Considering the associations into direct and indirect effects, weight of tubers per plant followed by average weight of tuber and number of tubers per plant found to contribute to the higher yield. |
