Effect of thidiazuron on microspore embryogenesis and plantlet regeneration in Chinese flowering cabbage (<i>Brassica rapa.</i> var. <i>parachinenis</i>)

This research aimed to obtain land characters and qualities data and to determine land suitability for clove and nutmeg and their spatial distribution in Nusalaut Island, Central Maluku Regency. The results showed that the land suitability for clove are marginally suitable class (S3) with the coverage area is 1452.38 ha or 66.51%, and the limiting factors are water availability and nutrient retention (wa, nr) limiting factors and unsuitable class (N) of 731.52 ha or 33.50 %. While the land suitability for nutmeg are moderate suitable (S2) with root media and nutrient retention (rc, nr) limiting factors and the coverage area is 123.75 ha or 5.66%, S2nr of 409.93 ha or 18.77%, slope (S2eh) limiting factor with the coverage area is 918.7 ha or 42.1% and the unsuitable class (N) with the area of 731.52 ha or 33.50 %. The land suitability of the clove and nutmeg is located in the Other Used-Areas (APL) with the area of 2183.63 ha, while total land units in the study area is 2697 ha.

“…One way to overcome this problem is by cultivating plants by utilizing narrow land such as using polybags. There are several advantages of using polybags as planting containers, namely, they are easy to move, plant development is easy to control, the nutrients given to plants are also directly absorbed by the roots, cultivated plants do not know the season, the composition of the planting media can be adjusted, saving space and planting space and efficient fertilization (Jia et al, 2019). According to Hayati (in Jin et al, 2022) growing media is one of the environmental factors that need to be considered.…”

The Effect of Cultiving Media and N Fertilizer Application on the Growth and Results of Flowering Cabbage (Brassica oleracea var. botrytis L.)

Tarigan

2023

Research to study the effect of a good combination of growing media and application of N fertilizer on the growth and yield of cauliflower (Brassica oleracea, L.). The research time was carried out from June 2022 to October 2022 at Raya Village garden, Berastagi District, Karo Regency, North Sumatra Province, with an altitude of 1,300 above sea level with latosol soil type and soil pH 6.8. This research was conducted from June 2022 to October 2022. This research was conducted with a factorial experiment of 3x2 = 6 + 1 controls arranged in a factorial randomized block design (RAK). The first factor was the composition of the planting medium (M), which consisted of 3 treatment levels, namely: Mo: Control (without mixture), M1: Soil + husk charcoal with a volume ratio (1:1), M2: Sand + charcoal husk with a volume ratio (1:1) , M3: Soil + sand + husk charcoal by volume ratio (1:1:1) . The second factor was the dose of ZA (N) fertilizer which consisted of 3 treatment levels, namely: N1 : 50 kg/ha, N2 : 100 kg/ha, N3 : 150 kg/ha . The observed variables were plant height, number of leaves, number of roots, fresh weight of plants, fresh weight of flowers/plant, dry weight of plants, initiation of flowering, flower diameter. Mixing plant media and N fertilizer can increase the growth and yield of cauliflower plants. M3N3 treatment ( Soil + sand + husk charcoal with volume ratio (1:1:1) + Nitrogen fertilizer 150 kg/ha, is the best treatment that can increase growth and yield of cauliflower on the number of roots (7.27 fruit), fresh weight of plants (7.95 g), dry weight of plants (2.69 g), initiation of flowering (6.00 hst), fresh weight of flowers/plant (6.98 g), flower diameter (3.09 mm).

“…When multi-actor knowledge networks bring together different stakeholders, the negotiation of the meaning and practice of sustainable agriculture is part of their interaction and contestation. Such "social" brings more sustainable results than purely rational top-down planning, especially in situations when decisions have to be taken on complex issues (Jia, Zhang, Cui, & Feng, 2019). To achieve mutual understanding of different stakeholders and enhance the transition towards sustainable agriculture, mediators or knowledge intermediaries play a key role through interaction facilitation, collaborative reflection, integration of various knowledge cultures.…”

Integration of Local Farmers' Knowledge for Sustainable Agriculture (Case Study of Horticultural Farmers in Waihatu Village)

Kakisina

2023

This research aims to explore farmer knowledge and learning practices with a focus on the role of informal knowledge and learning in strengthening agricultural sustainability and resilience. This research was conducted from May-June 2023 in the village of Waihatu, Kairatu District, West Seram Regency, Maluku Province, which is a center for horticultural crop production. This research uses a qualitative research design using case studies and in-depth interviews, observation, and document research. The results showed that the diversity of knowledge sources and forms of learning used by farmers and the special role of local farmer knowledge. That the knowledge potential of farmers is not utilized optimally and there are several ways in which various types of knowledge can be integrated by individual farmers by synthesizing knowledge from various sources, through farmer networks, both facilitated by formal agriculture and knowledge institutions, through collaboration between farmers and researchers as knowledge generators, and through multi-actor knowledge networks that bring together various fields. That dynamic context, complexity and local specificity of today's challenges facing agriculture and the many roles it is asked to fulfill requires more inclusive, flexible modes of knowledge generation, integration and sharing. All stakeholders and all types of knowledge need to be brought together on the same basis in the innovation process. To this end, policy frameworks and initiatives that promote interactive multi-actor approaches to development agriculture, can play a sizeable role.
