Abstract

At the selection stage in breeding with gamma irradiation mutation induction, seeds from the previous generation are needed to be planted in the field to obtain the next generation of mutants. The seeds before planting have undergone a storage period, during the storage period if the temperature, humidity, and storage conditions are not right it will affect the viability and vigor of the seeds which can reduce the germination of seeds in the field Tests to determine seed vigor can be done by conducting a conductivity test (DHL). The purpose of this study was to determine the conductivity value of each genotype of the third generation mutant and the percentage of germination of black soybean seeds during the storage period. This study used a non-factorial completely randomized design (CRD) with 10 mutant genotypes and 1 control (without irradiation), and each treatment was replicated four times. Observation variables were electrical conductivity/conductivity, germination rate, growth speed, growth synchronously, vigor index, and maximum growth potential. Based on the conductivity/DHL test, genotypes with high Conductivity/DHL values ​​have a low percentage of germination, but the percentage of germination is still above 80% during the storage period, so it is expected that they will still have high germination ability in the field. Keywords: electrical conductivity, black soybean, and conductivity.

Abstract

Jamur tiram merupakan jamur konsumsi yang disukai oleh masyarakat karena memiliki rasa yang enak dan nilai gizi yang tinggi. Jamur tiram dapat dibudidayakan dalam media (Baglog) yang berasal dari serbuk kayu atau bahan lignin yang telah lapuk dan dibungkus plastik dan disterilkan.Bahan baku serbuk kayu semakin sulit diperoleh karena berkurangnya pemanfaatan kayu, yang menyebabkan harga serbuk kayu semakin tinggi dan biaya produksi jamur akan meningkat. Oleh karena itu diperlukan alternatif limbah lignoselulosa yang diperlukan sebagai media untuk pertumbuhan jamur, salah satunya adalah jerami. Penelitian ini menggunakan perlakuan tunggal dalam rancangan acak kelompok (RAK) dengan empat ulangan. Perlakuan kombinasi media sengon dan jerami terdiri dari 8 taraf. P0 = Serbuk kayu sengon 100%; P1 = Serbuk kayu sengon 90% + Jerami 10%; P2 =Serbuk kayu sengon 80% + Jerami 20%; P3 = Serbuk kayu sengon 70% + Jerami 30%; P4 = Serbuk kayu sengon 60% + Jerami 40%; P5 = Serbuk kayu sengon 50% + Jerami 50%; P6 = Serbuk kayu sengon40% + Jerami 60%; P7 = Serbuk kayu sengon 30% + Jerami 70%. Percobaan diulang sebanyak empat kali. Hasil penelitian diketahui bahwa jamur yang ditanam pada media 100% serbuk kayu sengon menunjukkan pertumbuhan dan produktivitas terbaik dibandingkan dengan perlakuan lainnya.

Abstract

Patchouli (Pogostemon cablin Benth.) is one of the essential oil-producing plants which is Indonesia's leading export commodity so that it can contribute foreign exchange for the country. Patchouli production nationally is still fluctuating and the productivity of patchouli oil is still relatively low. Therefore, proper patchouli cultivation techniques are needed. Plant distance is an important factor in determining the quality and quantity of production. In addition, the use of superior varieties is also a technology that aims to increase the productivity, yield and quality of patchouli oil. This study aims to determine the interaction and analyze the growth and yield of three varieties of patchouli (Pogostemon cablin Benth.) at different plant distance. This research was conducted in October 2021 – March 2022 at the Experimental Garden of Agrotechno Park, Universitas Brawijaya, Jatikerto Village, Kromengan, Malang, East Java. The tools and materials used in this study were tractors, ovens, LAM, scales, hoses, alphaboard, polybags, stationery, cameras, patchouli seeds of Sidikalang variety, Patchoulina 1 variety, Patchoulina 2 variety, planting media, rainfall data, manure, fertilizer. Urea, KCL fertilizer, SP36 fertilizer, raffia rope and water. The design used in this study was the Randomized Block Design which was arranged in a factorial manner consisting of 6 treatment combinations and 4 replications, namely: V1J1: Sidikalang variety + 75 cm x 40 cm plant distance; V1J2: Sidikalang variety + 60 cm x 50 cm plant distance; V2J1: Patchoulina 1 + plant distance 75 cm x 40 cm; V2J2: Patchoulina 1 variety + 60 cm x 50 cm plant distance; V3J1: Patchoulina 2 variety + 75 cm x 40 cm plant distance; V3J2: Patchoulina 2 variety + 60 cm x 50 cm plant distance. The results showed that the treatment of varieties and plant distance had a significant effect on the components of patchouli plant growth. While the yield component of patchouli shows the interaction between varieties and plant distance. The conclusion of this study is that there is an interaction between the treatment of varieties and plant distance on the increase in fresh weight, dry weight and productivity of patchouli. The Sidikalang variety with a plant distance of 60 × 50 cm had the highest yield and oil quality compared to other treatments. The Sidikalang variety also had the highest growth compared to the Patchoulina 1 and Patchoulina 2 varieties. Likewise, the 60 cm x 50 cm plant distance treatment had the highest growth compared to the 75 cm x 40 cm plant distance.

Abstract

Superior hybrid watermelon seeds developed by university plant breeders are currently very limited, with most farmers relying on seeds from national seed companies. This research aims to identify the superior characteristics of watermelon plants, both qualitatively and quantitatively. This study employed a Randomized Block Design (RBD), with six F1 hybrid watermelon lines and four control varieties as factors. Data were analyzed using the F-test, and significant differences were further examined using the Least Significant Difference (LSD) test at the 5% level. Qualitative data were used to cluster analysis based on agronomic characteristics, calculated using NTSYS software. The results indicate significant variations in several morphological and agronomic traits among watermelon genotypes. Genotype WM 2210-1606 is superior in stem diameter, flowering time, and early harvest. Genotype WM 2210-1110 excels in vine and leaf length. GARNIS has the highest fruit weight, and WM 2210-1606 shows higher sugar content at the fruit's edge. Cluster analysis divides the genotypes into three main groups based on trait similarities. These variations highlight the potential for improving watermelon quality through breeding superior genotypes.
