SKRIPSI PENGARUH DOSIS DAN WAKTU PEMBERIAN THIAMIN TERHADAP PERTUMBUHAN BIBIT TEMBAKAU (Nicotiana tabacum L.) KEDU VARITAS GOBER
ABSTRACT
The obyective of this experiment is know the in- fluence of time and dosage of Thiamin aplication on Kedu tobacco (Nicotiana tabacum L) seedlings growth of Gober variety, this experiment was caried out at Secang village, Secang district, Magelang regency, from May until August 1987.
This experiment used Randomized Completely Block Design, arranged was factorial, with two factors and three replications.
The first factor was dosage of Thiamin 0,00 ppm/m² (D0), 0,15 ppm/m² (D1), 0,30 ppm/m² (D2), 0,45 ppm/m 2 (D3) and scond factor was time aplication this 0 days (P0) or this seedling together, 7 days seedling after and 14 days seedling after.
The result obtained were as follows:
1. The dosage Thiamin aplication at 0,15 ppm/(D₁) gi- ve the best result and significantly influence to the seedling growth height, seedling total leaf seed ling leaf width, seedling total root, seedling weight fresh and seedling dry weight. Whereas the stem diameter and seedling root lenght did'n significantly influence.
2. The best result of average seedling on treatment do- sage 0,15 ppm/m² (D₁) and this seedling aplication together (P0).
