<p>ABSTRACT</p><p>Drought stress in crop occurs due to imbalance between demand and supply of water. Crop responses to drought stress depend on their genotypes. Drought stress causes anatomical changes and root damage. The objective of this research was to study the effect of drought stress on anatomy and physiology of soybean root. The research was conducted at Laboratory of Microtechnique, Department of Agronomy and Horticulture, Bogor Agricultural University in November 2013. A Completely Randomized Design with two factors was used in the research i.e. soybean genotypes (Wilis, PG 57-1, SC 39-1) and PEG (0, 20%) with three replications. The result showed that genotype and PEG affected the size of the cortex, stele, and xylem. PG 57-1 genotype showed the decrease of cortical thickness, diameter of stele and the diameter of xylem, on the other hand, in SC 39-1, there was an increase. Drought stress (PEG 20%) could also cause damage to the root membrane as indicated by the occurrence of lipid peroxides. Wilis and PG 57-1 were tolerant while SC 39-1 was sensitive to drought stress.</p><p>Keywords:cortex, lipid peroxides, PEG, Schiff’s reagent, xylem</p>

Soybeans are a very important food requirement in Indonesia, but they often face drought problems. Drought stress causes inefficient nitrogen absorption and makes the stomata close early so photosynthesis is not optimal, resulting in reduced yield. This research was conducted from August 2020 to October 2020 in Demangan village, Sambi sub-district, Boyolali district with polybags in a plastic house. This research method used Factorial Completely Randomized Design (CRD) consisting of two factors and repeated 3 times. The first factor was soil moisture content consisting ie. 100%, 75%, 50%, and 25% of field capacity. The second factor, the growth phase consists of active vegetative, flowering, and seed filling. Observations included the number of branches, number of productive branches, number of trifoliate leaves, the weight of filled pods, and weight of 100 dry seeds. Drought stress reduced the growth and yield of soybean at 25% moisture content in the field capacity of the seed filling phase. The number of branches, the number of productive branches, the number of trifoliate leaves, the weight of filled pods, and the weight of 100 dry seeds decreased with the lowest value.

ABSTRAK<br />Tanaman nilam (Pogostemon cablin Benth) merupakan tanaman<br />atsiri utama di Indonesia. Saat ini sekitar 90% minyak nilam dunia<br />dihasilkan oleh Indonesia. Produktivitas dan mutu nilam sangat<br />dipengaruhi oleh faktor genetik dan lingkungan. Salah satu faktor<br />lingkungan abiotik yang sangat berpengaruh terhadap pertumbuhan dan<br />produksi nilam adalah cekaman kekeringan. Sampai saat ini informasi<br />mengenai toleransi nilam terhadap kekeringan masih sangat terbatas.<br />Untuk itu, sebuah penelitian pemanfaatan pupuk hayati mikoriza untuk<br />meningkatkan toleransi kekeringan pada tanaman nilam dilakukan pada<br />kondisi rumah kaca di Balai Penelitian Bioteknologi dan Sumberdaya<br />Genetika Pertanian pada bulan Januari sampai dengan bulan Juni 2003.<br />Percobaan menggunakan rancangan acak lengkap (RAL) yang disusun<br />secara faktorial dengan 3 ulangan. Faktor pertama 2 taraf aplikasi mikorisa<br />masing-masing dengan dan tanpa mikoriza. Faktor kedua adalah 4 taraf<br />cekaman kekeringan dengan tingkat pemberian air (KL) yang berbeda<br />masing-masing (1) tanpa cekaman kekeringan (100% KL), (2) cekaman<br />kekeringan rendah (75% KL), (3) cekaman kekeringan sedang (50% KL),<br />dan (4) cekaman kekeringan tinggi (25% KL). Aplikasi mikoriza dilakukan<br />1 bulan setelah tanam (BST), sedangkan perlakuan cekaman kekeringan<br />diberikan 2 BST. Hasil penelitian menunjukkan bahwa nilam yang diberi<br />mikoriza mempunyai pertumbuhan yang lebih baik. Kekeringan menekan<br />partumbuhan dan hasil tanaman nilam secara linier. Sebaliknya, cekaman<br />kekeringan mampu meningkatkan kadar minyak dan patchouli alkohol<br />daun nilam. Interaksi antara kedua faktor yang diuji terjadi pada parameter<br />panjang akar total dan kadar prolina daun nilam. Keberadaan mikoriza di<br />dalam akar mampu meningkatkan toleransi terhadap cekaman kekeringan.<br />Kandungan patchouli alkohol daun tertinggi dijumpai pada kombinasi<br />perlakuan aplikasi mikoriza dengan cekaman kekeringan tinggi (25% KL).<br />Kata kunci : Nilam, Pogostemon cablin Benth, mikoriza, cekaman<br />kekeringan, pertumbuhan, produktivitas, Jawa Barat<br />ABSTRACT<br />Use of mycorhiza bio-fertilizer in increasing drought<br />tolerance of patchouli plant (Pogostemon cablin Benth)<br />Patchouli (Pogostemon cablin Benth) is a primary essential oil in<br />Indonesia. More than 90 percent patchouli oil of the world is produced by<br />Indonesia. Productivity and quality of patchouli oil are strongly affected by<br />genetic and environmental factors. One of abiotic environment which has<br />strongly effected growth and productivity of patchouli is drought stress.<br />The information on the tolerance of patchouli to drought stress is limited.<br />For that purpose, an experiment of the effect of mycorhiza application and<br />drought stress treatments was conducted at a glass house condition in<br />Indonesian Agricultural Biotechnology and Genetic Resources Research<br />Institute, from January to June 2003. A factorial experiment was arranged<br />in a completely randomized design (CRD) with three replication. The first<br />factor was 2 mycorhiza treatments namely with and without mycorhiza<br />inoculation. The second factor were 4 drought stress treatments using<br />different water application level (FC), i.e. (1) without drought stress (100%<br />FC), (2) lowly drought stress (75% FC), (3) moderately drought stress<br />(50% FC), and (4) highly drought stress (25% FC). Mycorhiza inoculation<br />was applied 1 month after planting (MAP). While drought stress treatments<br />were applied at 2 MAP. The results of observation showed that the<br />inoculation of mycorhiza improved growth performance. Drought stress<br />reduced growth and production components linearly. On the contrary, the<br />drought stress was able to increase oil and patchouli alcohol contents in the<br />leaf. The interaction between the two factors treatment was found on total<br />root length and leaf proline content. The existing of mycorhiza in<br />patchouli root was able to increase drought stress tolerance. The highest<br />patchouli alcohol content of leaf was found at mycorhiza application and<br />highly drought stress (25% FC) combination treatment.<br />Key words: Patchouli, Pogostemon cablin Benth, mycorhiza, drought<br />stress, growth, productivity, West Java

Abstract Background A need for research searching for alternative rumen enhancers warrants immediate attention. The in vitro fermentation experiment was conducted using factorial arrangement of two factors of roughage to concentrate and seven level of red amaranth leaf powder percentage of total substrate in a Completely randomized design (CRD). Two factors, namely Factor A was two ratio of roughage (R) to concentrate (C) at 60:40 and 40:60 and Factor B was level of red amaranth (Amaranthus cruentus, L) leaf powder (RALP) supplementation at 0, 2, 4, 6, 8, 10, and 12% of total dietary substrate. Results Red amaranth leaf powder (RALP) contained phytonutrients both condensed tannins and saponins in addition with high macro minerals (Ca, K, and Mg). This experiment revealed innovations of the RALP supplementation by enhancing rumen propionate (C3) production, reducing acetate (C2) to (C3) ratio, reducing protozoal population and mitigating methane (CH4) production. Furthermore, rumen dry matter degradation percentages were remarkably enhanced (P < 0.001) by increasing RALP supplementation. Conclusion Plants rich in phytonutrients and minerals such as red amaranth leaf powder (RALP) have a vital and promising role in modulating rumen fermentation, mitigating methane production, as well as increasing substrate degradability.

Shallots (Allium cepa var. Aggregatum L) have many varieties that can be grown in the highlands and lowlands and one of them is the Batu Ijo variety. Nutrients N and K play an important role for plant needs. This research was conducted from March to June 2019 in Medan Baru, Bengkulu City. This study used a completely randomized design with two factors. The first factor was the dose of N fertilizer and the second factor was the application of K fertilizer. The application of N fertilizer had a significant effect on the number of shallots at week 2. The Urea dose given decreases the number of spring onions. For the best treatment at plant height is the treatment of Urea 300 kg/ha and KCl 50 kg/ha. Plant growth from week 2 to 5 increased significantly. The application of K fertilizer has an effect on the number of shallots at week 2 and the number of tubers. The higher the plant age, the more the number of leaves produced, but at higher doses, the number of leaves and the number of tubers decreased. The best treatment for the number of leaves produced was Urea 300 kg/ha and without giving KCl. For the best treatment of fresh plant weight, namely Urea 300 kg/ha and KCl 150 kg/ha, the best treatment fresh tuber weight was Urea 300 kg/ha and KCl 150 kg/ha, for tuber diameter the best treatment was 200 kg/ha of urea and KCl 100 kg/ha and for the number of tubers of Urea 0 kg/ha and KCl 150 kg/ha.Keywords: shallots, N fertilizer, K fertilizer

Whey waste contains organic materials, particularly high complex proteins and amino acids in the form of suspended and dissolved solids, however the utilization of whey as a organic liquid fertilizer still has a less attention. Thus the Utilization of the whey waste through anaerobic process to be used as a organic liquid fertilizer is the purpose of the research. This research was conducted using factorial design with completely randomized design (CRD) which consists of two factors: the yeast concentration (without yeast; 0.25 and 0.50 g/500 ml of whey waste) and the fermentation time (0, 3, and 5 days). The variables measured were the content of organic C, C/N Ratio, and Total N, P2O5 and K2O contents. The results showed that the fermented whey waste on the different fermentation time and yeast concentration had increased the organic C and C/N ratio, but decreased P2O5 and K2O contents. The utilization of whey combined with solid or other liquid wastes gave a chance to produce a quality organic liquid fertilizer
