In Indonesia, the superior sweet cassava varieties are still limited due to the situation on which the majority of the superior varieties -bitter varieties- are used as industrial raw material until now. Therefore the availability of new high yielding of sweet cassava varieties is still needed. Assembling varieties requires the support of germplasm that has identified its superiority. The research objective was to evaluate tuber yield, morphology, and physico-chemical properties of cassava tuber from sweet cassava germplasm. A total of 75 accessions were characterized in Jambegede research station in February-November 2016, using Randomized Block Design. Variables observed included plant height, number of plants at harvest, harvest index, number and weight of tuber yield, and starch content. Physico-chemical analysis of tubers was carried out on 15 accessions with high tuber yields. Plant height at harvest was 393.2 cm in average. There were 10 accessions of sweet cassava with high fresh tuber yields ranging from 36.61 ton.ha-1 to 61.64 ton.ha-1, i.e MLG 10366, MLG 10365, MLG 10318, MLG 10197, MLG 10325, MLG 10341, MLG 10018, MLG 10279, MLG 10298, and MLG 10263. Physico-chemical analysis showed that the average of HCN content was 9.40 ppm, moisture content of 59.5 %, starch content of 28.8 % wb, and amylose content of 11.0 % wb. The bitter cassava with steamed tuber texture not cracked had relatively higher levels of HCN and water content, which was 82.88 ppm and 74.8 %, while the starch and amylose content was relatively lower (15.8 % wb and 5.5 % wb).

Peanuts (Arachis hypogaea L.) are the second main commodity in the annual cropping pattern in lowland and dryland in North Lombok District of NTB Province. However, peanut productivity is still low, and it varies across regions, which might be due to the traditional crop management of farmers and the difference in land suitability classes. Effects of crop varieties and land suitability on the peanut productivity have not been evaluated in the Region. Thus, this study aimed to evaluate the productivity and profitability of peanut varieties at various land classification in KLU NTB. The experiment was arranged in a Split Plot Design consisting of three classes of land suitability as main plot and six peanut varieties as sub-plot with three replications. The results showed that the land suitability classes have a significant effect on the agronomic variables of peanut varieties, including plant height, number of branches, number of pods and productivity. The highest peanut yield was obtained at suitable land class (S1), followed by moderately suitable land class (S2) and marginally suitable land class (S3) at 2.37 ton.ha-1, 2.08 ton.ha-1 and 1.71 ton.ha-1, respectively. Likewise, the R/C ratio follows a similar pattern to productivity in various land suitability classes. The highest yield (above 2 ton.ha-1) in each land suitability class was produced by Kelinci variety, followed by Tuban, Bima and Talam varieties. Those varieties have potential prospective to be developed in North Lombok Regency.

Several species of Rutaceae have been widely used and commercialized in all regions in Indonesia. Some species of Rutaceae are consumed as fresh fruit and traditional medicine for various kinds of diseases, as well as to add aroma to various Indonesian culinary. Since 1959, Eka Karya Bali Botanic Garden (Eka Karya BBG) has successfully collected dozens of Rutaceae species with unknown potential. In addition to reporting the conservation of Rutaceae in Eka Karya BBG, this study aimed to screen the antifungal activity of Rutaceae methanolic extract toward Aspergillus niger, Cladosporium sp., and Fusarium solani. Leaves of 13 species of Rutaceae (Boenninghausenia sp., Citrus aurantifolia, C. maxima, C. medica, Clausena sp., Melicope sp., Micromelum sp., Murraya paniculata, Toddalia sp., Zanthoxylum sp., Z. alatum, Z. limonella, and Z. ovalifolium) were collected, cleaned, air-dried, soaked in methanol for three days, then evaporated using a rotary evaporator to obtain the plant crude extract. The in vitro inhibitory assay was conducted by the diffusion method. As a result, only C. medica, Clausena sp., and Z. limonella exhibited antifungal activity against those tested fungi. Their antifungal activity increased on day 2 post-treatment but slowly decreased on day 3. Thus, the result of this experiment can be used as preliminary data to researchRutaceae plant extracts as an alternative method to control pathogenic fungi. However, further research is needed to maintain and increase its inhibitory effect.
芦花科的几种植物在印度尼西亚的所有地区都得到了广泛的利用和商业化。芸香科的一些品种被用作新鲜水果和治疗各种疾病的传统药物，以及为各种印度尼西亚烹饪增添香味。自1959年以来，Eka Karya Bali植物园(Eka Karya BBG)已成功收集了数十种潜力未知的芸香科物种。本研究在报道芸香科植物在鄂卡山核桃地区的保存情况的基础上，筛选芸香科植物甲醇提取物对黑曲霉、枝孢霉和枯萎菌的抑菌活性。收集芸香科植物(Boenninghausenia sp.， Citrus aurantifolia, C. maxima, C. medica, Clausena sp.， Melicope sp.， Micromelum sp.， Murraya paniculata, Toddalia sp.， Zanthoxylum sp.， Z. alatum, Z. limonella和Z. ovalifolium)的13种叶片，清洗，风干，甲醇浸泡3 d，然后用旋转蒸汽器蒸发得到植物粗提物。体外抑菌试验采用扩散法。结果表明，只有草芽孢杆菌、克氏菌和柠檬芽孢杆菌具有抗真菌活性。抗真菌活性在处理后第2天升高，第3天缓慢下降。因此，本实验结果可为研究芜科植物提取物作为防治病原菌的替代方法提供初步数据。然而，维持和增强其抑制作用还需要进一步的研究。

Research on rice plant breeding to get superior black rice varieties with tender rice texture can be carried out by crossing Black Rice and Mentik Wangi variety. The rice lines derived from a crossing of these two varieties have recently reached the F6 line. The texture of rice is distinguished by the amylose content. The lower of the rice amylose, the more tender of the rice texture, and vice versa. This study aimed to find out the profile of amylose content and the grains morphology of the lines that will be developed as waxy pigmented rice. Analysis of amylose content was carried out using iodine-colorimetry methods. The quantification of amylose was measured based on the regression of the standard amylose curve. The results showed that all the F6 lines had the potential to be developed as waxy pigmented rice. Based on the Kruskall Wallis test, there was a variance in the amylose profile average of the eight genotypes. In terms of grains morphology, the line 482-17-7 and 482-17-18 had a combination colour between the two parents. In addition, there was a significant difference in grains size between the genotypes and the grain size of all lines were classified in the medium size. F6 lines resulted from the crossing between Black Rice and Mentik Wangi are recommended to be used as superior varieties of waxy pigmented rice.

To fulfill the demand of soybeans, the expansion of the planting area can be one of the choices through the conversion of marginal land by utilizing suboptimal land, such as saline soil. One of the plant breeding techniques to obtain tolerant plants to salinity is the use of chemical mutations, such as colchicine. The study aimed to reveal the effect of salinity on the characters of soybean plants (mutated with colchicine) and the effect of colchicine on the number of chromosomes and ploidy level. This study was conducted from January to March 2020 and carried out in the plastic house of Faculty of Agriculture, Universitas Sumatera Utara. The experiment was arranged in a Randomized Block Design with salinity levels (0 dS.m-1, 2 dS.m-1, 4 dS.m-1, 6 dS.m-1) as treatments and consisted of ten replications in each treatment. The result showed that the soybean plants were not successfully induced by colchicine at a concentration of 0.04 % with soaking duration of 10 hours, as indicated by the number of chromosomes and analysis of ploidy level. The soybeans that had been induced were planted in saline soil. There were significant effects observed on the productive branch, number of filled pods, and the weight of seeds per plant. Colchicine treatment did not successfully affect the number of chromosomes of soybeans but had an impact on the chromosome pattern. In addition, the salinity treatment of 4 dS.m-1 significantly affected the number of filled pods compared to the treatment of 6 dS.m-1.

Lombok upland rice is one of the cultivars that have the potential as a genetic source. However, Lombok upland rice is almost rarely found. Therefore, conservation was carried out through morphological characterization to provide genetic information. This study aimed to describe the characteristics of six Lombok upland rice cultivars, namely, Reket Putek Bulu, Reket Putek Buntung, Reket Bireng Bulu, Reket Bireng Buntung, Pare Beaq Sapit, and Beaq Ganggas. A completely randomized design was used, consisting of these six Lombok upland rice cultivars as treatments. Two superior cultivars were also used for comparison. The study revealed sufficient divergence for various qualitative and quantitative traits. Pare Beaq Sapit and Beaq Ganggas shared common morphological characters, and both were tall plants. The auricle and ligule colors of Reket Bireng Bulu were different from those of the other cultivars. Reket Putek Buntung had the latest flowering and harvesting age. Reket Putek Bulu and Reket Bireng Buntung had a high number of productive tillers. Six cultivars of Lombok upland rice were characterized to have morphological diversity, so that they are expected to be used as genetic material in rice plant breeding, thereby developed to avoid extinction.

Two cultivars of local rice, namely Mentik Wangi and Mentik Susu, have been grown around west to south flank of Merapi volcano. They are highly valued for their good taste and cooking characteristics. An attempt to introduce drought-tolerant rice varieties has been conducted by crossing them with two sources, namely Kasalath and Bluebonnet. Molecular-assisted selection using a set of SSR markers was applied to check the F1 and F2 generation trueness and segregation. This research was conducted in the facilities of Department of Agronomy, Faculty of Agriculture, Universitas Gadjah Mada, Yogyakarta. The research was a field experiment arranged in a completely randomized design, consisting of Mentik Wangi, Mentik Susu, Bluebonnet, and Kasalath, as well as their crossings’ F1 and F2 plants as treatments. The SSR markers used are RM72, RM228, RM518, and RM20(A). Polymorphism test of the parents showed that polymorphism exists between local and donor parents, thus these markers were considered eligible for the F1 and F2 tests. The heterozygous individuals of F1 were 75% for Bluebonnet × Mentik Wangi, 44.4% for Bluebonnet × Mentik Susu, and 46.7% for Mentik Wangi × Bluebonnet; all were consistent in every primer used. We could not confirm that the F2 populations showed segregation pattern that followed Mendelian segregation in some crosses due to too small size of the sample. Heterozygous individuals in F2 showed the differences pattern for each marker, indicating that the location of the SSR markers were far from each other in the genome.

A swampland has considerable potential in agriculture. This land has high soil acidity level, and high iron content. Therefore, the application of ameliorant to acid sulfate soil is essential to improve the soil and make it more suitable for rice cultivation. This study aimed to know the effects of phosphorus (P) from Moroccan Rock Phosphate (MRP) and fertilization on swamp rice (Oryza sativa L.). The experiment was conducted at the experimental location of Indonesian Swampland Agricultural Research Institute (ISARI), Puntik Village, Barito Kuala District, South Kalimantan and arranged in a randomized nested design with four replications consisting of 100 kg.ha -1 TSP (Control), 750 kg.ha -1 , 1,000 kg.ha -1 , and 1,250 kg.ha -1 Moroccan rock phosphate with four replications in each treatment. The yield component of grain increased significantly at 3.77 ton.ha -1 . The highest of grain yield was obtained in the application of 1,000 kg.ha -1 MRP. Meanwhile, significant positive correlation was observed between plant height and the number of spikelets per panicle. The application of phosphate fertilizer can increase soil pH, which affects the growth and yield of rice plants such as plant height and yield.

The application of phosphate fertilizer can increase soil pH, which affects the growth and yield of rice plants such as plant height and yield.","PeriodicalId":13282,"journal":{"name":"Ilmu Pertanian (Agricultural Science)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43086588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nutrients availability and plant's ability to absorb nutrients are essential factors in supporting plant performance. There are two forms of fertilizer as a source of nutrients for oil palm, which are single-nutrient fertilizer (SNF) and briquette compound-nutrient fertilizer (BCNF). This study observed the concentration, uptake, distribution, and efficiency of macronutrients in plant organs of oil palm seedlings with two different fertilizer types. An experiment using oil palm seedlings was arranged in non-factorial complete randomized design (CRD) with three treatments, namely control, NPK in the form of briquettes, and single nutrient fertilizer consisting of urea, TSP, MOP, and kieserite with doses adjusting the composition of the slow-release BCNF (16-10-24-0.75) in three replications with a total of 27 seedlings. The results showed that the concentration, uptake, and distribution of nutrients between treatments and control were not significantly different. The order of nutrient uptake in leaves and stems of plants was N > K > Mg and P, while in roots was K > N > Mg > P. In BCNF and SNF treatments, the biomass accumulation in the stems, roots, and leaves were at percentage of 41 %, 30 %, and 29 %, while in the control, the biomass accumulation in the roots, stems, and leaves were at percentage of 39 %, 33 %, and 28 %, respectively. BCNF treatment had a greater efficiency indicated by a higher nutrient use efficiency (NUE) value compared to SNF or control.
养分利用率和植物吸收养分的能力是影响植物生产性能的重要因素。油棕的养分来源主要有两种形式的肥料，即单养分肥料(SNF)和型煤复合养分肥料(BCNF)。本研究观察了两种不同施肥方式对油棕幼苗各器官中常量营养素的浓度、吸收、分布和效率的影响。以油棕幼苗为试验材料，采用非因子完全随机设计(CRD)，设置3个处理，分别为对照、NPK型压块和尿素、TSP、MOP、kieserite组成的单肥，剂量调节缓释BCNF(16-10-24-0.75)的组成，3个重复，共27株幼苗。结果表明，各处理与对照间养分的浓度、吸收和分布无显著差异。植物叶片和茎的养分吸收顺序为N > K > Mg和P，而根系的养分吸收顺序为K > N > Mg >p。在BCNF和SNF处理下，茎、根和叶的生物量积累比例分别为41%、30%和29%，而在对照处理下，根、根和叶的生物量积累比例分别为39%、33%和28%。与SNF或对照组相比，BCNF处理具有更高的养分利用效率(NUE)值。
