Abstract

Begonia is one of the world's largest genera of flowering plants that spread in various tropical and subtropical regions worldwide. However, deforestation, overexploitation, climate change, and pathogen-causing diseases have threatened the diversity of begonia. Diseases on begonia need to be handled seriously because the level of spread and damage can result in the death of the plant. Thus, this study was conducted to identify the main pathogens causing diseases in the begonia which is expected to be basic information in determining the effective control treatment. As a result, begonia collections of Eka Karya Bali Botanic Garden were mainly infected by three pathogenic fungi (Fusarium spp., Oidium begoniae, and Botrytis cinerea) and one bacterium (Xanthomonas begoniae).

Abstract

One type of cereal that can be used as a functional food is hanjeli (Coix lacryma-jobi L.). Hanjeli production has many problems, i.e., low productivity and long life. Hanjeli cultivation from ratoons has several advantages, including reduced production costs, shorter lifespan, and less water requirement. Fertilization of NPK and application of GA3 as gibberellin hormone are expected to increase the growth and yield of hanjeli. This study aims to determine the interaction effect between NPK and GA3 on the growth and yield of hanjeli from ratoon. This experiment was carried out at the Experimental Field of the Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, Sumedang Regency, West Java, from August to December 2020. The experimental design used a Randomized Block Design, while the treatment design consisted of 2 factors. The first factor was the dose of NPK fertilizer which consisted of 3 levels, namely 100, 200, and 300 kg. The second factor was the concentration of GA3, consisted of 3 levels, namely 0, 10 and 20 ppm. All treatments were repeated 3 times. The results showed that there was an interaction effect between NPK fertilizer application and GA3 concentration on growth and yield of hanjeli, namely plant height, number of tillers, number of branches, leaf area index, number of productive tillers, grain weight per plant, harvest index and grain size and hardness. At a high concentration of GA3, increasing NPK fertilizer dose could improve the growth, yield, and yield quality of the hanjeli.

Abstract

 The addition of cytokinin to the multiplication of white turmeric (Curcuma zedoaria) seedlings in vitro proved effective in shoot multiplication, but the addition of high cytokinin concentrations could cause stunted shoots and stunted growth. The addition of the hormone gibberellins (GA­3­) is often used in tissue culture for shoot elongation, so increasing the viability of plantlets. The experiment aims to determine the effect of GA3  and obtain the best concentrations of GA3 consisting of 0.50, 1, and 1.5 ppm GA3 on optimizing the growth of zedoary plantlets. The experimental parameters included the number of shoots, roots, leaves, plantlet height, and chlorophyll content observed at 6 WAP after subculturing. The results showed that giving 1 ppm GA3 had the best effect on optimizing plantlets' growth, namely the growth component of the number of shoots and plantlets' height.

Abstract

Inceptisols have problem in phosphate availability. Soil P content is very low available to plants because it is bound by soil colloids. One of the efforts to increase the P nutrient in the soil in a sustainable way by using P-Solubilizers that can dissolve phosphate in the soil so that it is available for plants. The purpose of experiment was to determine the effect of the combination dose of kaolin based P-Solubilizer and P fertilizer for improving P availability, P uptake, phosphatase, and maize yield on Inceptisols. The kaolin-based P-Solubilizer was used a consortium of phosphate solubilizing microbes (PSM) consisting of Bacillus subtilis, Burkholderia cepacea, Pseudomonas mallei, and Trichoderma asperellum. This experiment was conducted in the experimental field of the Laboratory of Soil Chemistry and Plant Nutrition, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, from July to December 2021. The experiment used a randomized block design (RDB) method with nine treatments and three replications, with details of 0 P-Solubilizer + 0 P-fertilizer; 100% P-fertilizer; 100% P-solubilizer; and combination 50%, 75 %, 100%, and 150% P-solubilizer with 50%, 75%, and 100% P-fertilizer. P-solubilizer 100% recommended dose 50 kg ha-1 and P-fertilizer recommended dose 100 kg ha-1. The results showed that the dose of 100% P-Solubilizer (50 kg ha-1) + 75% P (75 kg ha-1) showed the best results in increased P-availability (346,93%), P-uptake (312,5%), Phosphate activity (33,5%), and maize yields (48,09%) compared to without application of P-solubilizer and P-fertilizer. This consortium isolate could be developed as a P-Solubilizer with the ability to increase the efficiency of P up to 25%.

Abstract

Soybean production has not met domestic demand, causing dependence on imported soybeans. Increasing soybean production can be done by giving organic materials such as fertilizer and biostimulants. Applying Padina minor extract as a biostimulant and black soldier fly (BSF) fertilizer can be an alternative to increase the growth and production of soybean. The research aims to determine the effect of Padina minor powder extract, BSF fertilizer, and the combination of Padina minor powder extract and BSF fertilizer on the growth and yield of soybean. This research was carried out from April  to July 2021 at the Plant Physiology Laboratory and Greenhouse, Department of Biology, Andalas University, Padang. The experiment was arranged in a Completely Randomized Design with four treatments (control or without extract and fertilizer), Padina minor extract, BSF fertilizer, and the combination of Padina minor extract and BSF fertilizer) and six replications. The results showed that the extract of Padina minor did not significantly affect the growth and yield of soybean. BSF fertilizer significantly increased the number of leaves, branches, leaf area, chlorophyll b, and total chlorophyll of soybean. The combination of Padina minor extract and BSF fertilizer gave similar effects as BSF fertilizer on increasing the number of leaves, leaf area, chlorophyll b, and total chlorophyll of soybean.

Abstract

In the last three years, potato production in Indonesia fluctuated every year. One of the factors that cause low productivity of potatoes is weed. The presence of weeds in potato planting areas can inhibit plant growth and affect potato yields. The aim of this study is to determine the effectiveness of herbicide glufosinate ammonium 150 g/L to control common weeds in potato plants. This research was conducted in a farmer field in Lebak Muncang Village, Ciwidey District, Bandung Regency, West Java Province. The experimental design used was a randomized block design with six treatments and four replications. Weed control using the herbicide glufosinate ammonium 150 g/L at a dose of 2.75– 4.50 L/ha was completely (100%) controlled Eleusine indica, Galinsoga parviflora, Amaranthus spinosus, Richardia brasiliensis, and total weeds for up to 6 weeks after application without causing symptoms of poisoning and could increase the number of potato tuber per plant and yield of potato per plot.

Abstract

The Inoculation of beneficial soil microbes is an effective method for lowering doses of inorganic fertilizers. This study was aimed to observe and compare the effect of doses and formulas of Bacillus-coated NPK (BCN) and conventional NPK fertilizers on biomass, major macro-nutrient in soil and their uptake by shoots of lettuce (Lactuca sativa L.); as well as evaluate the potency of BCN for decreasing doses of NPK fertilizers. The greenhouse experiment was set up in a randomized block design with seven treatments and five replications. The treatments included one and a half doses of recommended NPK fertilizer and two BCN fertilizer formulas; control treatment was without any fertilizer. This experiment showed that NPK fertilizer had comparable effect with BCN on growth traits; but application of NPK and coated NPK had a potency to increase the fresh weight of lettuce up to 24-45% which was in line with the increase of shoot-to-roots ratio. The potassium (K) content in soil and their uptake in lettuce shoots depend on doses and type of NPK but Nitrogen (N) and Phosphorus (P) content in soil and in shoot were not determined by treatments. The results showed that the recommended NPK dose (200 kg/ha) for lettuce can be reduced up to 50%; moreover, 50% of BCN enabled to maintain the N, P and K uptake as well as the lettuce yield.

Abstract

Microgreen is a popular food product that is interesting to study and can be produced in the building with the support of artificial light, especially in terms of smart lights. This study aims to analyze the growth and yield response of red amaranth, red radish, and coriander microgreens under different types of light color treatment from smart lights. The study was conducted in August 2022 at the microgreen culture room, Department of Agronomy, Universitas Padjadjaran, Indonesia, using a completely randomized design with two factors, namely three levels of plant species and five levels of smart light color. The results showed differences in seed viability, first-day count, and the day the cotyledons were open among three microgreen species. Seed growth into microgreens had the same pattern, namely linear and positive, even in the light absence condition as the evidence of etiolation occurrence leading to the production of thin and yellow pale color of microgreens. The difference in light color is specific to each type of plant.  Red radishes thrived in all colors, although red light tended to do better. On the other hand, red amaranth was inhibited in red light and coriander in white light. Blue light is strongly recommended for increasing red amaranth and coriander microgreens yields.

Abstract

The environment is one important factor that must be considered in supporting sweet potato productivity. Environmental factors can be biotic and abiotic, including the availability of nutrients and microbes in the soil. This study aims to identify the nutrient content of the soil in wetland and upland, identify the total invertase microorganisms in wetland and dupland, and identify the relationship between soil nutrients and microorganisms during the growth of Cilembu sweet potato in dry and wetland agroecosystems. This research was conducted on upland and wetland in Cilembu Village, Sumedang Regency. The experimental design used was a single randomized block design (RBD) with six treatments and three replications:  A; Rancing, wetland, B; Biang wetland, C; Mencrang wetland, D; Rancing, uplands, E; Biang, uplands, F; Mencrang, upland. Parameters observed included pH, C-organic, total-N, available-P, exchangeable K, exchangeable Na, exchangeable Ca and exchangeable Mg, CEC, and total invertase-producing bacteria. The results showed that in wetland nutrient content such as N, P, exchangeable Ca,  Mg, Na, CEC, C-organic and pH tended to be more available. K content and abundance of invertase bacteria are more available in upland. The availability of invertase bacteria has a close relationship with the K content. The information generated in this study can be used as a basis for determining an effective location to produce good quality.
