Moringa leaf bokashi contains many nutrients but a low C/N ratio. Therefore, moringa leaf bokashi must be combined with another ingredient containing a high C/N ratio. This study aimed to obtain the appropriate proportion of moringa leaves and empty oil palm fruit bunches for making good bokashi according to standard organic fertilizers and their application dosage to okra plants. The experiment of the combination of moringa leaf and empty palm oil fruit bunches (1:1, 1:2, and 1:3) and the application dosage to okra plants (10, 15, 20, and 25 tons ha-1) were arranged according to a completely randomized design with three replication. The results showed that single moringa leaf bokashi with a C/N ratio of 2.8 became 6-7.5 in bokashi made from a combination of moringa leaves and empty oil palm fruit bunches. Bokashi, made from moringa leaves mixed with empty palm oil fruit bunches in a ratio of 1:1, has a crumb texture and is black. Bokashi, with a ratio of 1:2 and 1:3, has a slight crumb texture and blackish-brown color. Only the number of leaves was affected by the ratio of moringa leaves and empty palm oil bunches and the application dose. The composition of moringa leaves and empty oil palm fruit bunches and the application dosage did not significantly affect the growth and yield of okra plants. However, the growth and yield of okra plants tended to be better at a 1:2 ratios of 10 tons-1 application dose.

Abstract The germination phase of sugar cane is a critical period that determines productivity. This phase lasts until the sugar cane is three months old, and in this phase, sugarcane requires an adequate supply of water to support the formation of shoots. Poor soil conditions and high rainfall can cause the failure of bud formation. This study aims to determine the relationship between rainfall and soil permeability on the successful construction of sugarcane shoots. We divided the 1 ha research area into nine points (A, B, C, D, E, F, G, H, I) to observe plant growth and soil permeability. The growth factors measured included the number of stems, diameter, and plant height, measured zigzag. Intact soil samples at a depth of 0-15 cm were then analyzed in the laboratory using Darcy^s law to determine the value of soil permeability. The results showed variations in sugarcane growth in the nine research plots. The average number of sugarcane stalks is eight stalks/meter with a height of 159 cm and a diameter of 3 cm. This result is caused by the low soil permeability value of 0.13-0.5 cm/hour, which cannot compensate for the average rainfall in the budding phase, thereby suppressing plant growth by up to 50% of the average productivity that should be.

Growth and Production of Japanese Taro (Colocasia esculenta var. antiquorum) by Using Biofertilizer and Plastic Mulch Masyhur Syafiuddin(a*), Asmita Ahmad(a), and Dewi Sartika (a) a) Department.of Soil Science, Faculty of Agriculture, Hasanuddin University, Makassar, Indonesia Abstract Japanese taro production in Indonesia is around 20 tons/hectare, but it is still relatively low due to the low level of farmer management including fertilizing and watering especially in dry season. The aim is to determine the effect of biofertilizer and mulch on the growth and production of japanese taro plants. This research used a split plot design. The main plot was plastic mulch consisting of two levels, namely control and plastic mulch, while the subplots were biofertilizers, which consisted of two levels: control and biofertilizer- and with four replications. Each plot planted with 22 plants. Parameters observed were plant height, number of leaves, leaf width, fresh plant weight, plant dry weight, plant tuber yield, and number of tubers. The results are plastic mulch treatment had an effect on plant height with the largest average found in the M1 treatment of 55.98 cm, the largest average leaf width in the M1 treatment was 25.09 cm, the average fresh weight of the M1 plant was 197, 03 g, and the average dry weight of M1 plants was 22.50 g. The biofertilizer treatment affected plant height, with the largest average found in treatment B1 of 55.00 cm. The most significant average number of leaves in treatment B1 was 6.53 strands. The largest average leaf width in treatment B1 was 25.16 cm. Mulch affects the production of taro plants with the highest number of tubers found in the M1 mulch treatment of 32 bulbs with a weight of 881.50g/24.2m2. In contrast, the biofertilizer treatment was not significant in the production of taro plants. We conclude that mulching can increase the number of tubers and tuber weight and more effective than the biofertilizer treatment and it combination in the dry season.

Increased Yield of Three Shallot Varieties from Seed with Addition of Liquid Organic Fertilizer in the Highlands Agustina E Marpaung*), Bina Br Karo, Susilawati Barus, Rina C. Hutabarat, Rasiska Tarigan, Delima Napitupulu and Perdinanta Sembiring Research Center for Horticultural and Estate Crop, National Research and Innovation Agency (BRIN) Indonesia *) Corresponding Author: agus196[at]brin.go.id Abstract Shallot is a vegetable commodity that is widely consumed as a spice in cooking, so the need of the consumer is high. To supply this high consumption is needed increased productivity. Productivity can be increased by using varieties suitable for the growing environment, quality seeds, and proper fertilization. One of the uses of quality seeds is from seeds, but to obtain high production from seeds, appropriate fertilization is necessary. The research aimed to determine the use of liquid organic fertilizers and shallot varieties from true shallot seed (TSS) can increase yield in the highlands. This research was conducted in IP2TP Berastagi, Karo Regency, with a height of 1340 meters above sea level and andisol soil type. This research was conducted from May to September 2018. The design used was a factorial Randomized Block Design with 3 replications. The first factor is liquid organic fertilizer (LOF): Without LOF, Rabbit manure LOF, Fish fertilizer LOF, and Fish teillation LOF. The second factor is shallot varieties from seed: Bima, Trisula, and Tuktuk. The results showed that the application of LOF did not affect the growth of shallots from seeds. The Trisula shallot variety from seed can be adapted to grow and produce well in the highlands, while the Tuk-tuk variety is only adapted for growth and the Bima variety is less adaptive for growth and yield. The Trisula shallot variety from seeds given rabbit manure LOF increased the yield by 13.70 - 65.10%. The implication of this research is that the growth and production of shallots will increase in the highlands if there is an interaction between the type of fertilizer and the variety.

Optimizing the use of submergence and drought tolerant rice varieties to reduce the impact of climate change on swampland Izhar Khairullah, M Saleh, Yustisia, and D Riyanto Research Center for Food Crops, National Research and Innovation Agency (BRIN) Indonesia Abstract The swamplands is one of the prospective suboptimal land for agriculture. The land consists of tidal swamplands and freshwater land which are widely available in Indonesia. The hydrotopography of tidal swampland is strongly influenced by tide and neap of water, while in freshwater land it is largely determined by rainfall. Drought, flooding or deep inundation, and shifts in rainfall patterns as a result of extreme climate change have an impact on agriculture in decreasing food crop production, particularly for rice in swamplands. One strategy in anticipating the impact of climate change in agriculture, especially food crops (rice) is to use submergence and drought tolerant varieties as well as early maturing rice varieties. Rice varieties tolerant of submergence in swamplands such as Inpara 3, Inpara 4, Inpara 5, Inpari 29, and Inpari 30 Ciherang sub1. While drought tolerant varieties such as Inpari 18, Inpari 19, Inpari 20, Inpago 4, Inpago 5, Inpago 6, Inpago-8, and Inpago Lipigo-4. In addition to avoiding drought, early-maturing aged rice varieties such as Hipa 6 Jete, Inpari Si Denuk can be used, Inpari-34 Salin Agritan, Cakra Buana Agritan, Inpari 12 and Inpari 13. The purpose of this paper is to describe how to reduce the impact of climate change on swampland agriculture by planting submergence and drought tolerant rice varieties. By using submergence and drought tolerant varieties and early maturing varieties, it is expected to reduce and anticipate the impact of climate change, particularly for agriculture on swamplands.

Raya Jakarta - Bogor, Cibinong, Bogor, Indonesia *paul006[at]brin.go.id Abstract True seed shallot (TSS) has become an alternative material for shallot seeds to fulfil the lack of good-quality seed bulbs. Transplanting was the most popular TSS planting method for farmers. This technic uses seedlings as planting material. The seedling production was the most crucial stage in transferring technology from vegetative propagation (seed bulb) to generative propagation (TSS). Seedling production can be developed as a new unit system (seedling grower) to produce excellent quality propagation material. Nevertheless, production and strategy in seedling management are not widely known. Several techniques can be used to produce shallot seedlings, including technical seedling, use of seedling media, seed treatment and seedling harvest arrangements. The selection of seedling techniques and maintenance management is influenced by several factors, including environmental factors of cultivation, capital availability, labor and other site-specific conditions. This paper reviews the advantages and disadvantages of each technique and the strategy for selecting techniques and maintaining seedlings that are suitable to the specific conditions at the seedling site. The implications of this paper are expected to be used by seedling growers to improve the best practice of seedling production with local wisdom technology Keywords: true seed of shallot- seedling- local wisdom- nursery Share Link | Plain Format | Corresponding Author (Retno Pangestuti)

West Java. Indonesia Abstract Microalgae (Spirulina platensis), as an organic nutrition source, may play an important role in stimulating the nutritional needs of Pak Choy (Brassica rapa) in a hydroponic system. This study aimed to use S. platensis dry biomass as a nutrient source of Pak Choy grown hydroponically compared to commercial hydroponic nutrients (AB Mix) as a control in screenhouse conditions. The experiment was arranged in a factorial design, the first factor was maceration time (0, 1, and 2 weeks), and the second was the concentration of S. platensis solution (0.1, 0.5, 1.0 g/l, and AB Mix). The experimental design was arranged in a completely randomized design with three replications. The observed variables were plant height, total leaf, fresh weight of root, shoots, total weight, and chlorophyll content. The results showed that there was no interaction in all observed variables. The maceration treatments did not affect the plant growth, except for plant weight (23.6 g) and leaf width (0.8 cm). However, S. platensis concentration treatments affected all observed variables significantly (p<0.01). On the other hand, all treatments showed tip burns three to four weeks after planting. It concluded that organic substances from S. platensis dry biomass have a potential use as hydroponics nutrient solutions. However, further study needs to be conducted to obtain the optimum treatments (concentration and maceration time) to produce healthier vegetables.

Research Organization for Governance, Economy, and Community Welfare, National Research and Innovation Agency, Indonesia c. Assessment Institute for Agricultural Technology of South Kalimantan, Indonesia Abstract The tidal swampland in Central Kalimantan has the potential as a source of production and as a rice barn. Some obstacles in tidal swampland are high acidity and toxic elements that result in low rice yields. IAARD has several new superior rice varieties that can be used in swampland. However, not all of these varieties can provide high productivity in the same environment. Adaptive and tolerant varieties are needed as well as site-specific cultivation technology. This study aims to obtain adaptive and tolerant rice varieties in the tidal swampland. The adaptation test of several rice varieties was carried out in tidal swampland, Sei Jangkit village, Bataguh sub-district, Kapuas district, and Central Kalimantan. The activity was carried out from September 2021 to April 2022. The varieties planted, namely, Inpara-2, Inpari-32, Inpari Nutrizinc, and Baroma. They covered an area of 4 ha and involved eight cooperative farmers. The technology applied in the farming activity is tidal management which includes water management, ameliorant applicant, balanced fertilization, and control of pests and disease. ANOVA was used to determine the effect of varietal treatment on agronomic observation, followed by an average difference test with LSD at a 95% confidence level. Farmers^ preference data were analyzed by Kruskal Wallis and continued with the Mann-Whitney test at the 5% level if there was a significant difference. The results showed that Inpara-2 gave the highest grain yield (5.12 t/ha), Inpari-32 gave 4.48 t/ha, Inpari Nutrizinc 4.58 t/ha, and Baroma 4.98 t/ha. Farming analysis using the B/C ratio of the varieties planted ranges from 1.28 - 1.57, with Inpara-2 giving the highest B/C ratio (1.57), followed by Baroma (1.51). The Baroma and Inpari-32 varieties are preferred over other types because of the taste of cooked rice, aroma, and color of the rice. These two varieties are close to the rice quality of the local Siam Mayang variety based on farmers^ preferences.
