An experiment to evaluate the growth and yield of two sweetpotato clones in intercropping with maize was conducted in IPB experimental farm in Sawah Baru from December 2004 to April 2005. In intercropping, the two sweetpotato clones of CIP-1 and CIP-6 were planted among to maize rows. Planting space of sweet potato was 100 cm x 25 cm and maize was 100 cm x 12.5 cm in a plot size of 3 m x 3 m. Besides, the two crops were also planted in monoculture. The experiment was designed as a Randomized Block Design (RBD) and replicated three times. Dry matter of stem, leaves, and roots of the two sweet potato clones in intercropping were lower than in monoculture. The same response occurred for yield of storage root. The storage root weight of sweet potato clone, respectively, in monoculture and intercropping was 1.350 and 2.533 kg plot-1 of CIP-1 and 3.167 and 11.083 kg plot-1 of CIP-6. On the other hand, there was no significance difference in growth and yield of maize in monoculture (3.35 kg plot-1) and intercropping (3.13 kg plot-1). Land equivalent ratio of the intercropping maize with CIP-1 and CIP-6 were 1.7 and 1.4, respectively. It means that land productivity can be increased by those intercropping. Key words: Sweet potato clones, intercropping, maize

The aim of this research was to study the relationship between fruit drop and contents of auxin, polyamines, ACC, total sugar, and starch. Cultivars of mango used were Gadung 21 and Lalijiwo.The persisting fruit and abscising fruits were used to quantify auxin, polyamine, ACC, total sugar, and starch. The content of polyamine and ACC was determined on pericarp, auxin on seed, whereas the content of starch and total sugar was determined on mesocarp. The result of research showed that fruit drop was preceded by low content of auxin that increased the sensitivity of abscission zone to ethylene. The increased sensitivity of abscission zone to ethylene was supported by low content of polyamine and high content of ACC. The abscising fruit has high content of starch, but low in total sugar content. Key words : Mango, persisting fruit, abscising fruit, auxin, polyamine, ACC, total sugar, starch

The research consisted of two experiments, they were shoot multiplications experiment and root induction with anthocyanins content experiment. Randomized block design with two factors was used in the two experiments. In the first experiment BAP and IAA were used which were 0, 1, 2, 3 ppm and 0, 0.5 and 1 ppm, respectively. In the second experiment IAA and sucrose were used which were 0, 0.5, 1 ppm and 30, 40, 50 and 60 g/l. Addition of BAP 3.54 and 2.98 ppm without IAA to in vitro MS medium in the first experiment, significantly increased the number of shoots (33.21) and number of leaves (52.53) at 5 weeks after planting. MS medium with BAP 0.32 ppm without IAA produced maximum shoot heights (4.11 cm), while addition BAP up to 3 ppm significantly reduced number of roots and induced callus diametres (1.48 cm). Purple pink leaf colour was produced without BAP application. In the second experiment, addition of IAA 1 ppm with sucrose 52.18 g/l and IAA 1 ppm with sucose 48.36 g/l produced maximum of shoot number (15.01 shoots) and leaf number (29.16 leaves) at 8 weeks after planting, but the size of shoot and leaf were smaller. Maximum shoot height (10.03cm), number of root (35.4) and length of root (22.3 cm) were produced at the IAA 0.5 ppm and sucrose 30 g/l. The highest anthocyanins content (0.071 %) and number of plantlet (2.6) were produced by addition of sucrose 30 g/l. Anthocyanin and number of plantlet decreased quadratically with sucrose addition. Key words : Anthocyanin, In Vitro, Gynura pseudochina (L.) DC

Ultisol is a soil type with the widest distribution in Indonesia. However, ultisol is characterized with acid reaction and low content of organic matter and nutrients. Ultisol contains a high concentration of Al at a level that can interfere plant growth. The objective of this study was to evaluate the effect of lime and crop residue composts application on the activities of exch-Al and the soybean yield. A greenhouse experiment using Vertic Hapludult from Gajrug, Banten was conducted in a completely randomized design. Liming treatments with 0.0 and 20.7 tons/ha (equals to 1x exch-Al) were combined with the application of different crop residue compost from upland rice, corn, soybean and peanut. The dose of the compost at 0, 1 and 2% organic-C. In this study, soybean was used as the indicator plant. The results of this experiment indicated that the application of lime equal 1x exch-Al significantly decreased exch-Al and resulted in good plant growth and soybean yield. Application of different types of crop residue compost decreased exch-Al. On the unlimed and limed soils the application of upland rice residue compost at dose of 2% organic-C (D2) increased soybean yield (23.21 g/pot and 25.67 g/pot), 72.53% and 1.87% respectively. Key words : Liming, crop residue compost, exchangeable aluminum (exch-Al), soybean
