Abstract

Converting solid Vermicompost into liquid form is an alternative for garlic cultivation in the Dibawah Lake Solok region, and the cost is cheaper. A preliminary study evaluated the impact of applying solid Vermicompost (0, 5, 10, and 15 t/ha) on garlic growth and yield. A subsequent study examined the effect of applying solid Vermicompost in liquid form using a chitosan solution and identified effective NPK fertilizer doses to optimize local garlic growth and yield. The experimental design was a randomized factorial with NPK doses of 0, 100, and 200 kg/ha and Vermicompost concentrations of 0, 30, 60, or 90 g/L chitosan solution. The preliminary study demonstrated that applying 10 to 15 tons per hectare of solid Vermicompost combined with 100 kilograms per hectare of NPK fertilizer significantly increased garlic yield compared to no solid Vermicompost application. A subsequent study found that varying NPK doses from 0 to 200 kilograms per hectare and Vermicompost from 0 to 90 grams produced similar effects on local garlic growth and yield. However, yields remained lower than those achieved with 15 tons per hectare of solid Vermicompost. In contrast, substituting solid with liquid Vermicompost at all tested concentrations resulted in higher profitability than the 15 tons per hectare solid Vermicompost treatment, particularly for 100 NPK and 60 grams of Vermicompost in chitosan solution. That treatment was more cost-effective for farmers because it increased income by 63% and was more environmentally friendly than the solid form application in the Dibawah Lake Solok region.

Abstract

Shallots are essential for Indonesia's economy and food security. In West Sumatra, cultivating shallots in the highlands is more challenging than in the lowlands. Lowland areas have poor Ultisol soil, but its chemical properties can improve with cultivation. Using organic materials, such as goat manure and granular guano with dolomite, is one solution to this problem. Unfortunately, shallot farmers often apply excessive amounts of dolomite. The ideal dosage of guano and dolomite as calcium, phosphorus, potassium, and magnesium sources must be determined for optimal shallot growth. Using goat manure may reduce the need for other inputs like dolomite. Guano and dolomite combination treatments have never been used on Peking shallot varieties grown on Ultisol soil. This study evaluated the growth and yield responses of Peking variety shallots to dolomite and guano applications on Ultisol soil improved with goat manure as a base fertilizer. The experimental design was two-factorial, completely randomized, with three replications. The first factor was the dolomite dose, with three levels: 0, 2, and 4 tons/ha. The second factor was the dose of granulated guano, with four levels: 0, 100, 200, and 300 kg/ha. All experimental units received goat manure-based fertilizer at a dose of 10 tons/ha. Data were analyzed with ANOVA at 5% confidence, then with Duncan's Multiple Range Test if the treatment had a significant effect. The results showed that applying dolomite and granulated guano did not significantly affect the growth parameters or yield of Peking variety shallots.

Abstract

The farmer's interest in garlic planting is low because the yield is unsatisfied. One reason is the use of small cloves. Giving paclobutrazol is expected to increase the size of garlic cloves and bulbs. This research aims to determine the interaction between concentration and time of giving paclobutrazol, which produces the best size for cloves and bulbs. The research is a factorial, Completely Randomized Design. The first factor is the concentration of paclobutrazol:250 mg.L-1 and 500 mg.L-1 of water. The second factor is the time of applying paclobutrazol: 6 and 10, 8 and 12, 10 and 14 weeks after planting (w.a.p). Data were analyzed using variance, which will be continued with DNMRT at the 5% level. The results showed that giving paclobutrazol at 10 and 14 w.a.p resulted in the highest apparent stem diameter and yield, but even so, the weight of the largest and the smallest cloves was the lowest. Meanwhile, giving paclobutrazol at 6 and 10 w.a.p resulted in the highest weight of the largest cloves 1.95 g and the highest of the smallest cloves 0.55 g, even though the apparent stem diameter and yield were the lowest. Treatment of 250 mg.L-1 paclobutrazol resulted in the highest weight of the largest cloves 1.80 g.

Abstract

Shallots are a high-value horticultural commodity. But so far, they have been mostly developed in the highlands. Shallots are plants that like areas with hotter air temperatures, so they are suitable for cultivation in the lowlands. Still, the soil that is widely available in the lowlands of the city of Padang is Ultisol. Ultisol contains high clay, so the soil becomes dense, the available nutrients are low, and the ground has difficulty passing water. Using Ultisol as a land for planting shallots, it requires using organic fertilizer in large doses. One of the agricultural waste products that is available and has yet to be widely used in Lambung Bukik Village is rice straw. Rice straw is a waste that is difficult to decompose. Therefore, it is necessary to use a decomposer to get compost faster. Training on making rice straw compost and making demonstration plots was carried out in Lambung Bukik, Padang City, to support the development of shallot cultivation on lowland Ultisol. Farmers are very enthusiastic about learning to cultivate shallots and making organic fertilizer from rice straw.

Abstract

The quality of the Garlic seed bulbs needs to be improved by seed propagation through tissue culture techniques to get uniform and big cloves. Utilizing the suitable color spectrum of light is one way to stimulate plant morphogenesis. This study aimed to identify the influence of light color and obtain the best color in the morphogenesis of garlic callus explants. This research was carried out from June to September 2022 at the Tissue Culture Laboratory, Faculty of Agriculture, Universitas Andalas. This study used a completely randomized design with three treatment levels: red, blue, and white. The F test analyzed observational data at a 5% level, followed by Duncan's multiple Range Test (DNMRT) at a 5% level. The results showed light color influences embryogenic callus formation and shoot formation from garlic callus explants. Blue light is better than red and white light in inducing embryogenic callus, increasing the rate of explants forming shoots but giving no significant difference in the length of the shoot.
