บทคัดย่อ (EN): The effect of weeding frequency and fertilizer (N P K Mg 20:10:10:5) rates on the growth and budding successes of Hevea rootstock seedlings was evaluated at the nursery field of Rubber Research Institute of Nigeria, Akwete Substation. The weeding frequencies consisted of 24,12,8 and 4 times weeding per year, while the fertilizer rates were 200,100 and 0 kg/ha. Thus having a 4x3 factorial experiment fitted into a randomized complete block design with three replications. The result showed that seedlings in field weeded 12 times/yr had a significantly taller seedlings with wider stem girths compared to the plots with weeded 6 or 4 times/yr. The fertilizer rate effect indicated no significant difference in growth performance and budding successes of seedlings that received 200 kg/ha and those that had 100kg/ha N P K Mg. The interaction between weeding frequencies and fertilizer rates was significant with seedlings that received 100 kg/ha N P K Mg 20:10:10:5 and 12 times weeding per year being more robust and with a mean budding success of 76.2% relative to other treatment combination; hence could be said to be a more suitable fertilizer rate and weeding frequency for Hevea seedling root stock mainly in a humid forest region.
