No full textIn line with the increase number of populations, the shallot demand is also increase. Thus, some efforts are needed to increase the shallot production on the degraded agricultural land, especially on ultisol. This study aimed to (1) identify the best dose of organic matter and mycorrhiza and the interactions between these two treatments in increasing shallot production on ultisol, (2) analyze the improvement of chemical properties of ultisols using mycorrhiza and organic fertilizer, and (3) measure the increase of vegetative and generatif (production) growth of shallot using these treatments. The study was designed by factorial randomized block design with some levels. Treatment 1 (Mycorrhiza), M0 = Control, M1 = 10 g/polybag, M2 = 20 g/polybag, M3 = 30 g/polybag, M4 = 40 g/polybag, and Treatment 2 (Organic Fertilizer), P0 = Control, P1 = organic fertilizer (0.6 kg/polybag), P2 = organic fertilizer (1.2 kg/polybag), P3 = organic fertilizer (1.8 kg/polybag), P4 = organic fertilizer (2.4 kg/polybag). The results show that the mycorrhiza treatment just give the significant effect on the paramters of the wet and dry shallot weights. The highest result was found in the M4 treatment (13,9 dan 1,79 gr) and the lowest in the M0 treatment (7,89 dan 0,86 gr) for the wet and dry shallot weigths respectively. The organic fertlizer gives significant effects on all parameters, for the highest output was found in the P3 (30,24 cm, 38,47 leaves, 12,75 gr dan 1,58 gr) dan the lowest from P0 (12,58 cm, 9,57 leaves, 5,46 gr dan 0,86 gr) for the parameters of the height, number of leaves, wet weight and dry weight, respectively. The interaction between two paramters did not give the significant effect on the wet and dry weights. Fortunately, the interaction of the M4P4 treatment give significant effect on the height parameter (37,17 cm) and the M1P3 treatment give significant effect on the parameter of the number of leaves (46 number of leaves).The development of the shallot commodity in Indonesia is excelent. This can be monitored by the consumption of shallots which continues to increase in line with the increase in population. Cultivation of shallots usually utilizes bulbs for planting material. This is because the use of bulbs is easier and more practical. Besides that, the success rate is high. This study aimed to (1) identify the best formula/dose of organic matter and mycorrhiza and the interactions between the two treatments in increasing shallot production on ultisols, (2) analyze the improvement of chemical properties of ultisols using soil enhancers, and (3) analyzing the increase in the production of mini bulb shallots using soil amendments. The study used several levels of factorial randomized block design (RBD) with mycorrhiza and organic fertilizer.

The results showed that the interaction between mycorrhizal treatment and organic fertilizers had a significant effect. The highest yield on shallot plant height was in the M4P4 treatment, while the lowest was in the M3P0 treatment. The interaction between mycorrhizal treatment and organic fertilizers had a significant effect. The highest yield on the number of shallot leaves was in the M1P3 treatment, while the lowest was in the M3P0 treatment
IDENTIFIKASI KERAGAMAN GENETIK SORGUM LOKAL HASIL IRADIASI MENGGUNAKAN PENANDA MOLEKULER RPAD
Full text linkSorghum (Sorghum bicolor L. Moench) is an alternative food commodity with significant potential for development in Indonesia. However, its genetic diversity in Indonesia is relatively low. The low genetic diversity of sorghum prompts efforts to improve and search for new sources of genetic diversity, including through plant breeding. Radiation-induced mutation is a plant breeding technique aimed at obtaining new traits that are not present in the parent plants. Gamma ray irradiation can damage DNA, and during the repair process, DNA undergoes new mutations induced randomly. This study aims to investigate the agronomic characteristics, genetic diversity, and relationship among plants that have been irradiated with gamma rays using the Random Amplified Polymorphic DNA (RAPD) molecular markers. In this study, local sorghum varieties from Bandung, Demak, and Jember were subjected to gamma ray irradiation at doses of 0 Gy, 300 Gy, and 500 Gy to induce genetic diversity. The application of gamma ray irradiation doses had a significant impact on parameters such as viability, vigor, and morphology. The isolated DNA was analyzed using the Random Amplified Polymorphic DNA technique. OPA-12 showed the highest level of polymorphism among the four primers used. The bands produced by the four scored primers were analyzed using the NTSYSpc program to determine the level of relatedness between genotypes. The genetic distance between genotypes was considerably wide, ranging from 0.1 to 0.46, indicating the potential for crossbreedingSorgum (Sorghum bicolor L. Moench) termasuk komoditas pangan alternatif yang memiliki potensi cukup besar untuk dikembangkan di Indonesia. Namun tingkat keragaman genetiknya di Indonesia masih terbilang rendah. Rendahnya keragaman genetik sorgum memicu untuk memperbaiki dan mencari sumber-sumber genetik yang baru, upaya yang dapat dilakukan diantaranya melalui pemuliaan tanaman. Mutasi induksi radiasi merupakan pemuliaan tanaman yang bertujuan untuk mendapatkan sifat-sifat baru dan memiliki sifat yang tidak dimiliki oleh induknya. Irradiasi sinar gamma dapat merusak DNA dan selama proses perbaikan, DNA akan mengalami mutasi baru yang diinduksi secara acak. Penelitian ini bertujuan untuk mengetahui bagaimana tampilan karakter agronomis, keragaman geneitk, dan hubungan kekerabatan dari tanaman yang telah diiradiasi sinar gamma berdasarkan penanda molekuler Random Amplified Polymorphic DNA (RAPD), Pada penelitian ini sorgum lokal bandung, demak, dan jember di induksi keragaman genetiknya dengan iradiasi sinar gamma dosis 0 Gy, 300 Gy, dan 500 Gy. Pemberian dosis iradiasi sinar gamma memberikan pengaruh nyata pada parameter viabilitas vigoritas, dan morfologi Hasil isolasi DNA dianalisis dengan teknik Random Amplified Polymorphic DNA (RAPD). OPA-12 memiliki tingkat polimorfisme tertingi daripada ketiga primer lainnya. Pita yang dihasilkan dari empat primer diskoring dan dianalisis menggunakan program NTSYSpc untuk mengetahu tingkat kekerabatan antar genotip. Jarak genetik antar genotip terbilang jauh berkisar antara 0.1-0.46 sehingga berpotensi untuk dilakukan persilanga
