Organisme pengganggu tumbuhan (OPT) seperti hama, patogen, dan gulma menimbulkan masalah dalam budidaya tanaman sehingga perlu upaya penanganan yang tepat. Solarisasi tanah merupakan salah satu alternatif pengendalian OPT tersebut. Makalah ini membahas informasi tentang pengendalian organisme pengganggu tanaman dengan teknologi solarisasi. Beberapa komponen yang berperan dalam proses solarisasi yaitu radiasi matahari sebagai sumber energi, mulsa plastik sebagai pengubah sumber energi, serta lengas tanah sebagai penangkap dan penghantar panas yang dihasilkan plastik pada jeluk tanah yang lebih dalam. Solarisasi tanah bersifat ramah lingkungan dan dilakukan sebelum tanam dengan mengelola energi panas dari radiasi matahari. Solarisasi tanah terbaik yaitu dengan menggunakan lembaran plastik transparan karena bersifat tembus cahaya dimana sebagian besar cahaya ditransmisikan melalui lembaran plastik dan hanya sedikit yang diserap dan dipantulkan. Suhu tanah yang tinggi akibat solarisasi tanah dapat menekan patogen tanah, hama tanah, dan propagul gulma serta dapat meningkatkan kesuburan tanah, pertumbuhan dan hasil tanaman.

Soybeans are rich in protein and very appreciated by the public of Indonesia. However, soybeans decreased productivity and improved through the expansion of planting areas such as shallow swampy wetlands and the use of biofertilizers such as phosphate solubilizing bacteria (PSB), Azospirillum, mycorrhiza, and bio-organic fertilizer. The results of previous studies have shown that biofertilizer can increase rice productivity in lowland and tidal land. Furthermore, the biofertilizer can assist in providing the uptake of N and P and improve soybean productivity in the lowland area. Field research in shallow swampy areas in Ogan Ilir, South Sumatra Province. Random Group prepared five treatments with five replications. The treatments include biofertilizers, PSB, mycorrhiza, Azospirillum, and BOF.

Rice is one of the main sources of carbohydrates for Indonesian society. The development of new varieties depends on the availability of germplasm as the source genetic material. The development of new varieties can be done through artificial crosses (local cultivars and superior lines) for the creation of diversities. The research aimed to explore the genetics parameters from eight rice characters, for the selection program. The crossing was conducted by using four local cultivars and one pure line with diverse agronomic characters. Four hybrids (F1) were planted using completely randomized design with four replications, and five parental as the check varieties (landrace and pure line). The correlation coefficient was found that there was one character showed strong correlation almost all the character that is panicle weight. While high heritability was found in harvest age, panicle length, number of grain per panicle, 1000 grain weight, and plant high. Hybrids that showed negative heterosis for harvest age are from B14081H-296 x Salak and Dampak x Carogol, which have shorter harvest age compared to the average of the parental plant which is dominant gene action and additive.

The brown planthopper (BPH)-resistant rice, early maturity, and aromatic are expected by both farmers and consumers. The traits have been combined through gene pyramiding and some promising rice genotypes obtained. However the genetic control of BPH resistance and maturity is quantitatively inherited, it is therefore both molecular and phenotypic assessments would be tremendously helpful in selecting promising genotypes. The study aimed to obtain genotypes with such valuable traits. Rice lines were analyzed using molecular markers i.e., RM586, RM589, RM8213 (BPH resistant gene markers); RM7610 and RM19414 (early maturity markers), and IFAP (Internal Fragrant Antisense Primer) for detecting aromatic, and INSP (Internal Non-fragrant Sense Primer) for non-aromatic rice. Phenotypic assessment was performed for brown planthopper resistant-related traits, such as chlorophyll content, stomatal conductance, and trichome density. Other evaluations were heading date and aroma (using 1.7% KOH solution). Results showed that molecular markers for evaluating BPH resistance genes (Bph3, Bph4, Qbph4, and Bph17), aroma (fgr gene), and heading date (Hd2 and Hd3 genes) could differentiate genotypes, and they serve as perfect markers, except for heading date markers. Seven genotypes i.e., #2, #3, #4, #5, #6, #10, and #11 were related to all traits expected based on molecular marker analysis. Meanwhile, genotypes #1, #2, #4, #6, and #11 were similar to their parents based on phenotypic analysis. Pyramiding program based on molecular and phenotypic markers enables us to combine three valuable traits into one rice genotype as presented in this study

The germination period is a critical phase of abiotic stress, including salinity stress. Invigoration can be done to reduce the effect of salinity stress and speed up the germination process. This research was aimed to find out the effect of invigoration to mitigate salinity stress of soybean seed germination. This research was conducted in the Greenhouse of Faculty of Agriculture, Siliwangi University. The experiment was arranged in a randomized block design with factorial patterns and three replications. First factor was the level of salinity of seawater, consisted of 3 levels ( 0% = EC= 0,6 mS cm-1; 10% =EC = 7,69 mS cm-1 ;and 20% = EC =11,4 mS cm-1). The second factor was invigoration, which consisted of 4 levels (water as control, mangosteen peel extract, turmeric extract, and mixture of mangosteen peel extract + turmeric extract with a ratio of 1:1). Results showed that there was no interaction effect between the invigoration and salinity stress on all parameters observed, but there was an independent effect of invigoration on soybean vigor and salinity stress. The salinity stress had a significant negative effect on seed germination. The invigoration of mangosteen peel extract or turmeric extract was able to maintain soybean seed vigor under salinity stress conditions. Therefore the invigoration could mitigate the effect of salinity stress of soybean seed germination.

Foxtail millet has the potential to be developed as a healthier food alternative because of its high nutritional value. Disease such as leaf blight caused by Bipolaris setariae is one of the limiting factors in Foxtail millet productivity. One of the efforts to control the pathogen is by utilizing resistant varieties. In this study, two candidate varieties and two germplasm accessions were tested to determine the level of resistance to Bipolaris setariae leaf blight. The study was arranged based on a complete randomized design with six replications. Each test material was inoculated with the spore suspension at 4 WAP. Disease intensity was observed based on the disease scoring at 7, 9, and 11 WAP. AUDPC value is calculated based on the intensity of the attack at a particular observation time. Grain weight was recorded and statistically analyzed. The two candidate varieties of foxtail millet Pagamogo and Tedamude from Nagekeo Regency showed a moderately resistant response to leaf blight and had the lowest AUDPC values of 907.69 and 912.31. The highest increase in AUDPC values was observed in the initial observation period at 0-49 DAP.
