ABSTRACT The use of mini-cuttings is an option for obtaining sweet potato propagules of excellent quality. The objective of this research was to evaluate the production and quality of sweet potato roots propagated by mini-cuttings in different types of trays and ages of seedlings. Six treatments, resulting from the factorial 2x3, were evaluated: two types of trays (162 and 200 cells, with 31 and 18 mL of substrate per cell, respectively) and three ages of seedlings (39, 46 and 53 days after placement of mini-cuttings in trays), in a randomized block design, with five replications. Seedlings characteristics, production and quality of roots were evaluated. Higher number and dry weight of leaves per seedling were observed in the tray with 162 cells than in trays with 200 cells. The younger seedlings (39 days) had a lower number of leaves, dry weight of leaves, stem, roots ant total (leaves + stem + roots) than seedlings of other ages. There was no difference in root production depending on the type of tray, regardless of the age of the seedlings. For the 162-cell tray, the age of the seedlings did not affect the production of roots. On the other hand, for the 200-cell tray, higher roots production was observed on seedlings 39 days age compared to seedlings with 53 days. No differences were observed among the roots of different treatments for titratable acidity, and levels of sucrose, reducing sugars ant total sugars. It is recommended to avoid old seedlings, that is, it is recommended to use seedlings with a maximum of 43 days after planting of mini-cuttings for trays with 200 cells, while for trays with 162 cells no difference in root production was observed with the different ages of the seedlings.

Utilization of acid soils for food crop development must be carried out because of land conversion. The main problem in acid soils is the unavailability of P nutrients. Utilization of Arbuscular Mycorrhiza on acid soils has been found to contribute to the availability of P nutrients. This study used a factorial randomized block design with 2 factors, namely the application of tofu waste and arbuscular mycorrhiza. Tofu waste dosage consists of 0, 125, 250 and 375 g/polybag and Arbuscular Mycorrhiza application, namely: 0, 6, 12 and 18 g/polybag. The results showed that the application of tofu waste at a dose of 375 g / polybag affected significantly and gave the best results for the parameters of plant height, number of branches, wet weight and dry weight of soybean crop stover. While the application of arbuscular mycorrhiza with the best dose of 18 g / polybag affected significantly to fresh weight and dry weight of the roots of soybean. However, the interaction between the two treatments did not affected significantly to all observed variables.

<p><strong>Status of cadmium and rhizome yield l/temuireng (Cur¬ cuma aeruginosa Roxb.) at by d fferent dosages phos¬ phatefertilizer</strong></p><p>Cadmium is a heavy metal which is for human being. The concentration of Cd in the soil will increase if phosphate fertilizer is applied, because Cd is available in the sediment rock of phosphate as a raw material for phosphate fertilizer. Recently it is said that simplicia of medicinal crops originated from Asia is contaminated with heavy metals. That contamination mainly derives from Ihe environmental growth. Theefore, the research on the status of Cd in rhizomes Curcuma aeruginosa Roxb. due phosphate fertilizer is essential to be conducted. The experiment was conducted in the experimental garden of Research Institute for Spice and Medicinal Crops from August 1997 - June 1998. The experiment used polybags which were illed with 25 kg Bogor dry latosol soil mixed with I kg of rice husk and 2 kg cattle manue It used randomized block design (RBD) with four replications and ive samples each treatment. The treatments were (I) no NPK; and 8 dosages of TSP, (2)0; (3)2.5; (4)5; (5)7.5; (6)10.0; (7)12.5; (8)15.0; and (9)20.0g/ polybag respectively. Each TSP treatments was added with 1 5 g uea and 19 g KCI/ polybag. The plant wee harvested at 8.5 month after planting. The results of experiments showed that application of2.5; 5; 7.5; 10; 12.5; 15; and 20 g/polybag of TSP increased dry weight of simplicia from 24.3- 40%. The content of Cd in rhizomes, produced by plant with 5 up to 20 g TSP fertilizer was 1.181 - 2.756 ppm. The Cd content was higher than tolerance limited value as determined by laws of heavy metal in Japan (I ppm) and WHO (0.24 ppm). While fertilizer teatments of 0 and 2.5 g TSP produced rhizomes with Cd content 0.630 - 0.945 ppm, and it is still under tolerance limited value by Japan, but, higher than WHO laws. Due to high Cd content in rhizomes (1.181 - 2.756 ppm), those simplicia can not be used as row material for medicine.</p>
