Abstract

This study aims to identify and determine the viability and vigor of seeds of some species of plants in Ambon city market. This research was conducted in the Laboratory of Seed Control and Certification Institute (BPSB) Passo and at the Faculty of Agriculture, University of Pattimura Greenhouse Ambon from February to April 2012. The method used was testing seed with duplo system and using T test with three replications. There were eight seed plant types tested, i.e corn, mustard, long bean, eggplant, bitter melon, cucumber, large chili, and cabbage. Responses observed consisted of viability parameters, i.e. germination percentage, germination rate, and germination rate index, and vigor parameters consisted of simultaneity sprouted seeds and sprouted seeds pace. The results showed that seeds in the market city of Ambon, such as corn, mustard, long beans, eggplant, bitter melon, cucumber, large chili, and cabbage were in excellent quality, as shown by the results of the seed germination rate which reached 90.33 - 97.33% at laboratory test, meanwhile at greenhouse test the rate reached 90.33 - 94.33%, strong vigor with synchrony seed grow were 51.00 - 64.67%, and the growth rate reached 29.46 - 33.65%.

Abstract

Nutmeg (Myristica fragrans H) is native to Indonesia, which has been known as herbal plants.  Its planting areas, however, are often hindered by the presence of unwanted plants. Weeds are among the plant pest organisms (PPO), which inhibit the growth, development and productivity of crops. Identification of dominant weed species is the first step in determining the success of weed control. This research was conducted in Hutumury Village, Ambon, with an aim to determine weed species composition and dominant weed species in producing and non producing (juvenile) nutmeg plantations. The process of data collection in the field was undertaken by a survey method. The results showed 18 weed species were found in the plantation of non producing phase and 13 weed species were found in the plantation of producing phase.  In the producing plantation, the dominant weed species was Selaginella plana Heron with an SDR value of 57.80%. In the non producing plantation, the dominant weed was also Selaginella plana Heron with an SDR value of 44.42%.  The overall dominant weeds in the nutmeg plantations belonged to the annual broad leaf weeds.

Abstract

The decline of mustard (Brassica juncea L.) production can indicate a plant nutrition problem. The purpose of this pot experiment was to determine the response of green mustard to the application of NPK and Chitosan fertilizers which were applied at the same time. The experimental design completely randomized design with three replications and two factors, namely NPK fertilizer with five levels of dosage, namely 0.0 g/plant, 0.4 g/plant, 0.8 g/plant, 1.2 g/plant, and 1.6 g/plant, and Chitosan with four levels of concentration, namely: 0%, 10%, 20% and 30%. Observed variables were plant height, number of leaves, average leaf area, total leaf area, root length, root fresh weight, stem diameter, and plant fresh weight. The results of the study found that the use of NPK and Chitosan fertilizers increased plant growth indicated by plant height, number of leaves, leaf area and  root length, as well as plant yield indicated by plant fresh weight. There was no interaction effect between the two treatments but independently both  treatments have a positive effect on growth and yield of green mustard. The higher the dose of NPK fertilizer and the concentration of chitosan will increase the effect. The best treatment composition recommended for green mustard cultivation was NPK fertilizer with a dose of 1.6 g/plant and chitosan with a concentration of 20%.

Abstract

Nutmeg (Myristica fragans Houtt) is one of the plantation crops that has high economic value in addition to cloves, rubber, coffee, tea and cocoa. To get good plant growth, quality seeds are needed and to get good seeds, sufficient nutrients are needed for the growth of roots, stems and leaves. Planting media in nurseries must be of good quality so that the seeds produced are also of good quality, one of the quality planting media is using sago ela compost and using young coconut water as a growth regulator. This study aims to obtain the optimal dose of sago ella compost and young coconut water concentration on the growth of nutmeg seedlings in nurseries. The treatments used sago ella at a dose of 300 g/pot and 600 g/pot), and young coconut water with concentrations of 0%, 25% and 50%. The results showed that the sago ella treatment had a significant effect on the variables of plant height, leaf number and root length, but had no effect on stem diameter and root crown ratio, while young coconut water treatment had an effect on seedling height and number of leaves, but had no effect on root length. , stem diameter and crown to root ratio. The real interaction was only on plant height
