Abstract

Tomatoes are one of the daily necessities for people. In general, consumers favor tomatoes with few seeds. Therefore, there must be efforts made to improve the quality of tomatoes, one of which is to reduce the number of seeds, even if it is possible to make tomatoes without seeds (seedlessness). By applying Gibberellic acid (GA) during the growth phase of tomato plants, it is possible to enhance tomato quality through technology. The application of GA to certain plants can reduce the number of tomato seeds and increase their sweetness. It is necessary to discover a way to use GA-containing natural ingredients to prepare for the high cost of synthetic GA. Onions are one of the natural ingredients that contain GA. Thus, this study aimed to examine the effect of applying onion extract as a source of GA to obtain the optimum concentration of onion extract that can improve the quality of tomato fruit. The experimental design utilized Randomized-Group Design with five different treatments: no spraying, spraying with 25%, 50%, 75%, and 100% onion extract. According to the findings, the application of onion extract improved the quality of tomato fruit. This condition is reflected by a decrease in the number and weight of seeds per fruit and an increase in the fruit's vitamin C content. Therefore, it is essential to conduct this research to produce inexpensive, high-quality tomatoes to sustain the economy and increase farmers' income

Abstract

Tangerines (Citrus reticulata var. Tejakula) were destroyed in 1984 by CVPD, allegedly because the use of chemicals was too intensive, resulting in land degradation. Since ten years ago, these oranges have been successfully cultivated again using healthy organic cultivation, but farmers have difficulty getting organic fertilizer. This research aimed to identify and isolate the Arbuscular Mycorrhizal Fungi (AMF) on tangerines cv. Tejakula, their colonization of the roots and effect on soil fertility. Exploration was conducted by collecting root and soil samples in tangerine cv. Tejakula production centers are in the Tejakula District, Buleleng Regency. Spore isolation was conducted using wet filtration and centrifugation techniques, while root colonization by AMF was carried out using the staining method with trypan blue. The isolated spores are composited into AMF biofertilizer using volcanic sand as a carrier medium. The biofertilizer was then tested for its effect on soil fertility with three treatment levels of AMF spore doses (0, 20, and 40 spores/50 g of carrier media per plant). The results of exploration, isolation, and identification showed that three genera and six species of AMF were found. The spore density ranged from 17 to 32 per 100 g of soil (mean 24.17 ± 2.02 spores). The average root colonization by AMF was very high, ranging from 90 to 100%, and the application of AMF biofertilizer at a dose of 20 and 40 spores per plant provided soil fertility was much better than the control (0 AMF spores per plant).

Abstract

Badung River, a primary irrigation source for the subak system in South Denpasar, has been reported to contain excessive levels of heavy metals, exceeding the standard quality for irrigation water. Corn cultivated on subak systems irrigated by this irrigation source had heavy metal residues in its roots and kernels. Long-term consumption of corn containing heavy metals such as Pb, Cd, Cu, Cr, and Hg will cause toxicity to plant tissues and the human body. This study examined the content of heavy metals in soil and corn plants in subak systems in South Denpasar, which are irrigated with water from the Badung River. Remediation of the soils contaminated by heavy metals was conducted using rice straw and husk biochar (Br), coconut coir and shell biochar (Bc), vegetable and fruit waste biochar (Bw), and lignohumic biochar (Bl). The study also evaluated the effect of applying biochar on growth and yield of corn grown on soils contaminated by heavy metals. The results of this study showed that the heavy metal contents in the soil and irrigation exceeded the threshold for soil and water quality standards. The application of Bl yielded the highest biomass fresh weight and seed weight at 14% moisture content compared to other treatments. The Bl treatment also resulted in the best performance in binding and translocating heavy metals based on the bioaccumulation and translocation values ??of the biochar types. Hence, it can be concluded that the most suitable biochar for the remediation of heavy metal-contaminated paddy soils in subak systems is lignohumic biochar.

Abstract

Purpose: This research aims to analyze the effect of organic and inorganic fertilizer packages on the growth of Tejakula tangerine plants and changes in soil chemical properties after being given organic and inorganic fertilizer packages. Research methods: The method used in this research was a Randomized Block Design (RAK) with 1 (one) factor. The treatment tested was the fertilizer package dose (P), consisting of 3 levels, namely organic fertilizer/cow manure (Po), organic cow manure + 22.6 g Urea fertilizer + 4 g KCl fertilizer + Phonska Plus 15 fertilizer -15-15 dose 84 g (Ph), and organic cow manure fertilizer + Urea fertilizer dose 22.6 g, KCl fertilizer dose 4 g, Phonska Plus fertilizer 15-15-15 dose 84 g + mycorrhizal biofertilizer + liquid organic fertilizer (POC) probiotics (Pc). Each treatment was repeated 8 times to obtain 24 treatments. Findings: The response to the fertilizer package had a significant to very significant effect on plant growth, such as increasing plant height, increasing the number of primary branches, increasing stem diameter and number of leaves. The fertilizer package that gave the highest response to plant height, number of leaves, while the increase in stem diameter had the same effect. Primary branch augmentation is the most influential Ph package but is not significantly different from PC. The effect of fertilizer packages on changes in soil chemical properties is that pH is neutral, DHL is classified as low to very high, C-org is classified as high, N-tot is classified as medium, P-available and K-available is classified as very high. Implication: The effect of mixed organic, inorganic and biological fertilizers and probiotic POC provide the best response to plant growth and increase DHL in the soil.
