Abstract

The experiment of seed treatment and storage longevity on cacao seed valiability was. conducted at Seed Science and Technology Laboratory, Departement of Agronomy, Faculty of Agriculture, Bogor Agriculture University since March to July 1995. The objectives of this experiment were to find out the optimum dosage of fungicide treatment and storability on cacao seed. Split plot design was used in this experiment; main plot were storage periods i.e. I, 3, 5, 7, and 9 weeks and .sub plots were dosages of fungicide (active ingredient carbendazim + mankozeb) 0, 2, 4, 6, g/kg of ,seed with 3 replication. Each unit consisted of 40 seeds. Result (the experiment indicated that control seed (without fungicide) were infected by fungi 90.67 % on the first week and its germination capacity was only 57.33 %. Fungi infection increased rapidly after 1 week and its caused the viability lost. Application of 2, 4, 6 g fungicide/kg of seeds inhibited fungi growth and that treatments maintained seed viabilility until 9 weeks of storage periods. There are no significant difference among fungicide dosage, except on index vigor; application of 4 and 6 g (of fungicide result lower index vigor. Better fungicide dosage was4 .21g/kg of seeds based on quadratic regression Y = 20.80 + 43.10 X - 5.12 X2 (Y = germination capacity, X = dosage fungicide). Dominant fungi infected on seed storage were identified as Fusarium sp and Aspergillus sp. The storability of cacao seed with fungicide treatments on 9 weeks of storage period were still relatively high, the germination capacity more than 80% and the seeding vigor were not different among of all storage periods

Abstract

The objective of the research was to determine the effect of GA3 application on the flowering of Anthurium andreanum cv. Avo Cuba. The experiment consisted of two factors namely dosage and frequency of application: once or twice with one half dosage each. The result showed that GA3 increased leaf area, length of flower stalk, and the number of flower produced, shortened the time of flower emergence and harvest date. GA3 did not influence flower size and vase life. The frequency of application had no effect on Anthurium flowering. There was no interaction of dosage and frequency of application. Dosage of GA3 at 10 mg per plant gave good effect on reproductive characteristics.

Abstract

An experiment of transplanting one and two nodes of green Bambusa vulgaris branch cutting from water culture the field was carried out with the application of chicken manure 0.0, 0.2, 0.4, 0.6, and 0.8 kg/plantlet, with based fertilizer Urea, TSP, and KCl 0.50, 0.50, and 0.50 kg/plantlet, respectively. Split plot design was used, with chicken manure as main plot and number of nodes as sub plot. All the combination were replicated thrice. Chicken manure 0.4 kg and Urea 0.50, TSP 0.25 and KCl 0.50 kg/plantlet is relatively needed to transplant green Bambusa vulgaris branch cutting from water culture to the field. Plantlet with two nodes had better growth ability than one nodes on 12 and 14 weeks after transplanting, although no significant differences observed at the initial and the end of the experiment.

Abstract

Intercropping of maize, rice, and cassava is commonly practice by subsistent farmer on rainfed agriculture in Indonesia. In general grain yield of rice in intercropping is lower than monoculture sole crop. This due to the fact that rice varieties planted in intercropping was bred and selected under elite, monoculture crop environment. Field experiments to evaluate grain yield relative stability of the three selected rice breeding materials planted in association with maize and cassava were carried out in Pekalongan (Lampung), December 1994 - September 1995. Tb153e-Tb-1 and Tb47h-Mr-17 are relatively stable in respect to grain yield. Individual mass selection in these two population will be practiced in association with maize and cassava.
