This study was aimed to obtain the best combination of organic-inorganic fertilizer, the best triacontanol concentration and both interactions for increasing clove growth. This study used a Randomized Complete Block Design (RCBD) with two factors. The first factor was the organic-inorganic fertilizer dosage package that consisted of 6 levels, i.e no fertilizer, 100% recommended dosage of inorganic fertilizer (r.d.i.f), 25% recommended dosage of organic fertilizer (r.d.o.f) + 75% r.d.i.f, 50% r.d.o.f + 50% r.d.i.f, 75% r.d.o.f + 25% r.d.i.f, 100% r.d.o.f. The second factor was the concentration of triacontanol that consisted of 3 levels, i.e no triacontanol, 2 mg L-1 and 4 mg L-1. The results showed that the application of 25% r.d.o.f + 75% r.d.i.f produced the best clove growth, but it was not significantly different from the combination treatment of the two other types of fertilizer as indicated by the greatest improvement on stem diameter, branches number, leaf area, chlorophyll a, chlorophyll b, total chlorophyll and carotenoids. Clove plants did not respond to the application of triacontanol at a concentration of 2 mg L-1, but gave a negative response to the application of triacontanol 4 mg L-1 on the plant height and leaf area variables. The interaction of the two factors did not have significant effects on all variables. Keywords: chlorophyll, morphology, nutrient dynamics, physiology, vegetative growth

Laboratory-produced alginate-bead inoculum of ectomycorrhizal (ECM) fungi Cortinarius sp. and Gomphidius glutinosus, fungal commercial products ECtovit® and Trichomil®, bacterial commercial product BactoFil B®, and commercial rooting stimulator Vetozen® were applied to a peat-perlite (1:2, v:v) rooting substrate of Norway spruce stem cuttings collected from 4-year-old nursery-grown seedlings immediately before the insertion of cuttings into the substrate. The application of beads free of fungi and the substrate without an additive were the other treatments. The cuttings were rooted in vessels (60 cuttings per vessel, 180 per treatment) placed in a glasshouse and arranged in a randomized complete block design. The cuttings were estimated for one growing season (approximately for 26 weeks) after their insertion into the rooting substrate. Rooting % of the cuttings ranged from 45 (mycelium-free beads) to 75 (control) according to treatments, 64 on average. No significant differences among treatments were found in % of ECM morphotypes, total ECM colonization of roots (%), and growth parameters of shoots and roots of the cuttings. The applied microbial additives were not sufficiently efficient to form treatment-related ectomycorrhizas that were formed by naturally occurring ECM fungi. Inoculation by the ECM fungus Cortinarius sp. and application of Trichomil had a partial stimulative effect on the shoot growth of cuttings. Shoot and root growth parameters were not significantly correlated with total ECM colonization, except for a negative dependence of the root number in Trichomil treatment. A higher concentration of K but lower concentrations of Ca and Mg in Ectovit treatment than in the other treatments were detected.

Traditional medicines have been used in both developed and developing countries for a long time, one of which is longevity spinach (Gynura procumbens). Its plants are one type of plant that is used by the community to treat various diseases with their flavonoid content. This plant produces various flavonoids, such as quercetin, which can be optimized by providing shade and increasing nitrogen nutrients by giving biochar and fertilizing. This study aimed to determine the effects of biochar, shade, and fertilizer on the growth and quercetin content of Gynura procumbens plants. This research was arranged in a randomized complete block design (RCBD) with two factors. The first factor was the administration of biochar at four doses, consisting of B0 (without biochar), B10 (biochar 10 tons/ha), B15 (biochar 15 tons/ha), and B20 (biochar 20 tons/ha). Meanwhile, the second factor was the intensity of the shade with three levels of treatment, namely, I0 (without shade), I50 (50%), and I70 (70%). The results showed that the addition of 15 ton/ha of biochar with 70% shade increased the quercetin content by 0.51%.

Diversification of plant species is needed to anticipate price fluctuation of vegetables. Intercropping system compared to monoculture can give more benefits to farmers. The arrangement of plant spacings of sweet corn and cabbage variety is expected to result in higher yields and benefits in intercropping. The field experiment, which had the objective to study the effects of plant spacing of sweet corn and cabbage variety on yields of sweet corn and cabbage in the intercropping system, had been conducted from March to July 2008. The experiment was carried out at the dryland farming area at Candikuning Village, district of Baturiti, Tabanan regency, 1.200 m asl. In the experiment, a randomized complete block design with two factors namely plant spacing of sweet corn (120 cm x40 cm, 180 cm x 40 cm and 240 cm x 40 cm) and variety of cabbage (Green Nova and Summer-Autumn) were used. Plant spacing of cabbage was 60 cm x 40 cm. All treatments were replicated four times. The results of the experiment showed that the effect of interaction between plant spacing of sweet corn and cabbage variety in intercropping was not significant on yields of sweet corn and cabbage. Individually, sweet corn plant spacing of 120 cm x40 cm gave the highest fresh weight of cob without husk (10,91 t ha"'), which was 44.50% and 80.93% respectively higher than the spacing of ! 80 cm x 40 cm and 240 cm x 40 cm. The spacing of 180 cm x 40 cm resulted in not the significantly different fresh weight of cob with husk but gave the highest fresh weight of cabbage heads (56.101 ha'1), which was 27.36% higher than that at sweet corn spacing of 120 cm x 40 cm and was not significantly different from that at 240 cm x 40 cm. Cabbage variety Green Nova gave the highest head (56.101 ha1), which was 14.48% higher than variety Summer-Autumn. Intercropping between cabbage variety Green Nova and Sweet corn at 180 cm x 40 cm spacing resulted in the highest benefit (Rp. 20,488125 t ha'1), which was Rp. 3,335500 higher than the average benefit of cabbage monoculture. The efficiency of land use in intercropping was higher (LER: 1.69) than in monoculture (LER: 1). It is suggested to use cabbage variety Green Nova intercropped with sweet corn at I 80 cm x 40 cm spacing. An experiment studying the effect of cabbage intercropped with sweet corn and other short season vegetables planted after harvesting cabbages is also suggested.

Borneo sour eggplant, a popular indigenous fruit vegetable in Borneo, has become an important fruit not only to local people, but also to tourists who visit Borneo. One of the challenges in planting this crop is lacking information, particularly in finding suitable media for its growth, eventually inhibiting local farmers from growing the crop commercially. This study was conducted to investigate the effects of 4 growing media compositions (M1: topsoil, M2: topsoil and compost, M3: topsoil and cocopeat and M4: topsoil, compost and cocopeat) on the germination and growth performance of sour eggplant seedlings. The experiment was tested in a randomized complete block design (RCBD) with 10 replicates. At the end of germination period, seeds planted in M4 medium produced the highest germination rate of 96.67% and was significantly different (P < 0.05) from those sown in other growing media. However, the performance of the seedlings in terms of height, stem diameter, number of leaves and length of leaves showed significant increase (P < 0.05) in M2 medium. This study has demonstrated that M2 medium could improve the growth performance of the seedlings and therefore is recommended as suitable growing media for planting sour eggplant.
