In addition to carbohydrates, rice contains other minerals that function to growth and development of vital human organs. On the other hand, the content is influenced by genetic and milling processes. Indonesian Centre of Rice Research (ICRR) has genetic collection resistant to strains of the brown plant hopper (BPH). Genotypes were studied to assemble the pest-resistant varieties with high iron (Fe) and zinc (Zn) content. This study aims to determine the BPH-resistant lines that had high and stable Fe and or Zn content. The study was conducted in XRF Laboratory, ICRR Sukamandi, West Java in 2015. Fe and Zn were determined by using XRF machine with a system of performance-based X-ray. Total 20 rice lines that resistant to BPH was used Fe and Zn content on brown and polished rice were evaluated duplo. The results showed that milling generally decreased the content of Fe and Zn at rate 56.31% and 20.54%, respectively. The highest Fe content was found in BP19564b-WBC-1-1-4-3 (12.25 ppm), while the highest Zn content in BP19564b-WBC-1-9-8-3 (26.35 ppm). Genotype BP19564b-WBC-1-9-4-2 and BP19564b-WBC-1-9-8-3 exhibited the lowest in reduction Fe and Zn content, respective, from brown to polished rice.

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is the major disease in rice plants causing considerable economic losses. The objective of the study was to evaluate the resistant International Rice Bacterial Blight (IRBB) lines against bacterial leaf blight and the identification of Xoo pathotype from Central Java Province as the basis recommendation of the resistant varieties assembly with the background of resistant genes to overcome BLB disease. The evaluation of Xoo isolates from 22 districts in Central Java Province on IRBB lines was conducted in the rainy season 2016-2017 using split plot with three replications. The main plot was 15 IRBB lines, while the subplot was 110 Xoo isolates. Among 15 lines of IRBB, there were 10 lines have functioned as pathotype examiner of Xoo. The results obtained 6 lines were reacted resistant, namely IRBB5, IRBB7, IRBB8, IRBB57, IRBB64, and IRBB66. The IRBB66 line can be used as a resistant elder for the assembly of BLB resistant varieties because it has a combination of pyramiding resistant genes that were effective against BLB in some areas of Central Java Province. Pathotype IX was only found and dominant in Pemalang. Pathotype X was obtained in six districts of Tegal, Brebes, Banjarnegara, Purbalingga, Purworejo, and Grobogan. Pathotype XII was the most dominant prototype in 15 districts. Assembling of resistant varieties with resistant gene backgrounds based on the existence of a specific Xoo pathotype in the field can reduce the severity of BLB disease.

This research aims to determine the growth of Brassica plant species under various planting media. The study was conducted in a room at Building A, Faculty of Agriculture, Campus 2, Universitas Singaperbangsa Karawang, in Margasari Village, East Karawang District, Karawang Regency, West Java. The experiment took place from April to May 2024. The research method employed a Randomized Block Design with a factorial pattern consisting of two factors. The first factor is the Brassica family (t), divided into three levels, while the second factor is the planting media (m), also divided into three levels. There were a total of nine treatments, each repeated three times, resulting in 27 experimental units. Each unit contained seven plant samples. The effects of treatments were analyzed using analysis of variance (ANOVA), and if the F-test at the 5% significance level was significant, a post hoc Duncan Multiple Range Test (DMRT) was conducted. The experimental results showed an interaction between Brassica family and planting media on growth parameters, including plant height growth rate, leaf emergence age, fresh weight, and dry weight. Cabbage plants grown in soil yielded the best results in terms of fresh weight, while purple cabbage plants grown in cocopeat media performed best in terms of dry weight. Radish plants grown in peatmoss media exhibited the best growth rate, leaf emergence age, fresh weight, and dry weight. Broccoli plants grown in soil showed the best results in terms of leaf emergence age, while broccoli plants in cocopeat media excelled in fresh weight.

The diminishing amount of land available for agriculture and the growing demand for nutritious food have made it necessary to find alternative sources of fresh vegetables. Urban farming, especially the cultivation of microgreens, can help meet this demand. Microgreens offer several advantages, such as time and cost savings, and they require minimal space while growing quickly. However, the optimal spacing for different types of microgreens is not extensively documented, as research on microgreens is still limited in Indonesia. The Brassicaceae family is one of the most commonly cultivated families for microgreens. This study was carried out at Room A, Faculty of Agriculture, Singaperbangsa Karawang University, Campus 2. The experimental method used was a factorial randomized block design (RBD Factorials) with two treatments for varieties and three for spacing, repeated five times, resulting in 30 experimental units. Factor I, Varieties, consisted of v1 (Tosakan) and v2 (Shinta). Factor II, Spacing, consisted of j1 (1 cm x 1 cm), j2 (1 cm x 2 cm), and j3 (2 cm x 2 cm). The data were analyzed using an analysis of variance (Uji F) at a 5% level. If the results of the analysis of variance were significantly different, the study continued with a multiple range test (DMRT) at a 5% level to determine the best-performing treatment. There was an interaction between the treatments for microgreen varieties and spacing on parameters such as plant density, dry weight of the plant, and fresh weight. There was a significant effect of the variety on the parameter of chlorophyll content, and a significant effect of spacing on the parameters of plant growth rate and the age of leaf appearance. Additional types of plants are needed to determine significant differences related to spacing and their interactions.

The objective of this research was to determine the trait variance in black soybean lines in terms of yield and yield components. The materials used were F8 lines generated from hybridization of two local varieties, i.e. black seeded Ceneng and greenish yellow seeded Godek, and then selected under single seed descent method, except SC-39-1, SC-62-2 and GC-74-7 that were generated through bulk selection method. The results showed that the traits between plant genotypes were significantly different, except number of productive node and number of unfilled pod. Total variance was contributed more by number of filled pod, seed weight per plant and 100 seed weight. Seed weight per plant and 100 seed weight had high heritability with genetic variance and broad-sense heritability which were significantly different from zero. These characters are important for further selection to improve yields of black soybean lines.Keywords: black soybean lines, broad sense heritability, total variance
