Abstract

The research was conducted at Seed Science and Technology Field Experimental and Laboratory, Faculty of Agriculture, Bogor Agricultural University since January until July 1998. Randomized Block Design was used in this experiment which consist of two factors and three I replications. The first factors were row spacing 60 cm x 25 cm (J1) and 60 cm x 45 cm (J2) and the second factors were application of 100 ml paclobutrazol/plant with concentration 0 ppm (P1), 125 ppm (P2), 250 ppm (P3) and 500 ppm (P4). The plant height was increased at narrow spacing especially at 0 ppm paclobutrazol. Paclobutrazol application reduced plant height, increased stem diameter and it's caused minimal lodging at generatif period. The highest seed production per plot was resulted at 60 cm x 25 cm with 250 ppm and 500 ppm of paclobutrazol (146 % and 155 % as compared with control treatment), and the highest seed production per plant showed at 60 cm x 45 cm and 60 cm x 25 cm with 500 ppm of paclobutrazol (197 % and 198 % compared with control treatment). Paclobutrazol125 ppm, 250 ppm, and 500 ppm increased flower diameter, number seed per flower, 1000 seed weight, germination capacity, and seed vigour. The optimum combination of treatment was showed at 60 cm x 25 cm and 250 ppm of paclobutrazol.

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

Landscape plant nurseries are propagation and growing areas for trees, shrubs, ground cover plants, vines, water plants and herbs that are associated with several stakeholders such as landscape consultants, maintenance companies, contractors, and ornamental plant sellers. Nurserymen play a crucial role in providing plants for landscape projects, but the limited visibility of some nurseries poses a challenge to the procurement process. To address this issue, it is necessary to conduct a study that maps the location of nurseries and creates a database in several landscape plant production centers to facilitate consumers in meeting their plant needs. The study aimed to inventory plant diversity, analyze procurement and marketing practices in various ornamental plant centers, and assess the impact of different aspects of nurseries on plant application. Conducted from November 2023 to March across 10 districts in Bogor, Cianjur, and Depok regency, the research used descriptive quantitative analysis and correlation analysis to identify relationships between various aspects of plant procurement to identify key aspect for nurseries development. The research findings indicate a considerable diversity of plants within the production centers, with a total of 805 varieties across 10 districts in Bogor, Cianjur, and Depok regency. Despite 76% of these production centers employing conventional procurement methods, they are sufficiently able to meet the plant needs of their users. The study recommends policy initiatives focusing on plant specifications and net pricing, establishing a real-time plant database, and mapping nursery distribution locations to enhance procurement efficiency, benefiting both consumers and producers.

Abstract

Urbanization and rapid population growth have reduced agricultural land, impacting food security and environmental sustainability. This study aims to identify the agricultural landscapes in six districts of Bogor City and the landscapes surrounding farmer groups' gardens, analyze environmentally friendly urban agriculture practices and their benefits, and provide recommendations for the development of urban agriculture. Data were collected from 40 farmer groups through surveys, interviews, and questionnaires, supplemented by land cover analysis using processed Sentinel-2 image data. The results showed that the South Bogor sub-district has the largest proportion of agricultural land (10,70%), while the Central Bogor sub-district has the smallest proportion (0,04%). The landscape around farmer groups' farms in central Bogor is dominated by built-up areas, while in the peripheral it is more diverse. Most farmer groups have adopted environmentally friendly farming systems, utilizing organic and inorganic waste as agricultural inputs and using technologies such as hydroponics and aquaponics to maximize yields on limited land. However, the application of such technologies faces challenges related to cost and technical knowledge. Urban landscape agriculture provides benefits in improving the aesthetics of the cityscape, encouraging social interaction, and improving food access. The development of urban landscape agriculture is directed at preserving existing agricultural land, developing productive green open spaces, utilizing vacant land, and using simple technology and selecting commodities that are suitable for the environmental and social conditions of the community.
