Abstract

Tujuan penelitian adalah untuk mengetahui komponen hasil dan hasil beberapa genotip ubi jalar yang ditanam di lahan basah dan lahan kering dengan pemberian kombinasi pupuk KCl dan bokashi jerami. Penelitian dilaksanakan di Kebun Percobaan UNPAD Ciparanje Jatinangor, Kabupaten Sumedang, Jawa Barat dari bulan Februari hingga Juli 2015. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) pola faktorial, yaitu faktor genotip yang terdiri dari 4 genotip dan 1 check, dan faktor kedua kombinasi bokashi jerami dan KCl terdiri dari 6 kombinasi dan 1 kontrol. Masing-masing satuan percobaan diulang 2 kali, sehingga secara keseluruhan terdapat 70 satuan percobaan di tiap lahan. Penelitian menunjukkan komponen hasil dan hasil ubi jalar lebih baik di lahan basah daripada di lahan kering. Genotip 95 [265 (653)] lebih dominan di lahan basah sedangkan genotip Rancing lebih dominan di lahan kering. Kombinasi pupuk 50 kg/ha KCl + 20 t/ha bokashi jerami dapat meningkatkan komponen hasil dan hasil ubi ubi jalar di lahan sawah, sedangkan kombinasi pupuk  50 kg/ha KCl + 15 t/ha bokashi jerami dan 100 kg/ha KCl + 15 t/ha bokashi jerami dapat meningkatkan komponen hasil dan hasil ubi ubi jalar di lahan kering.The  aims of this study were to see the difference characters of genotype in two agro ecosystems, wet and dry lands fertilized with KCL and straw Bokashi.  The research was conducted at the Experimental Field of Faculty of Agricultural UNPAD Ciparanje Jatinangor from February to July 2015. The research was carried out using Randomized Block Design (RBD) two factorials. The first factor was genotype, consisted of 4 genotypes and 1 control, second factor was combination of KCl and straw bokashi that consisted of 6 combinations and 1 control. The study was repeated twice so there were 70 treatments. Storage root yield component and storage root yield growth were better in wet land than dry land. Genotype 95 [265 (653)] was dominant in wet land and Rancing was dominant in dry land. Combination of fertilizers 50 kg/ha KCl + 20 t/ha straw bokashi could increase storage root yield component and storage root yield in wet land, while in dry land combination of fertilizers 50 kg/ha KCl + 15 t/ha straw bokashi and 100 kg/ha KCl + 15 t/ha straw bokashi could increase storage root yield component and storage root yield.

Abstract

Agricultural soil is possibly threatened by lead (Pb) contamination due to the intensive use of fertilizers. The rhizobacteria were recommended for the bioremediation of soils contaminated by low concentrations of Pb. The experiment was conducted to observe the Azotobacter's ability to proliferate in Pb-contaminated broth and to decrease the Pb availability in soil, Pb uptake by sweet potato roots, and sweet potato growth. The resistance test was performed by growing five Azotobacter isolates in N-free broth with various Pb levels. A pot experiment was conducted in a factorial randomized block design to test three levels of Pb in soil and two Azotobacter isolates. The results showed that Azotobacter Azv4 and A. choroococcum were resistant to 100 mg L-1 Pb in N-free broth. In the pot experiment, Azotobacter Azv4 Inoculation caused less Pb in soil and roots of sweet potatoes grown in Pb-contaminated soil than A. choroococcum. Either Azotobacter or Pb soil did not influence vine length. However, Azv4 was more prominent in increasing branch number, root volume and length; higher Pb in soil reduced branch number but did not affect root parameters. Azotobacter Azv4 increased more shoot and root dry weight compared to A. choroococcum, but both isolates did not change the shoot-to-root ratio (S/R). The Pb contamination only reduced root dry weight and reduced the S/R. This research considered utilizing rhizobacteria Azotobacter for reducing Pb levels in soil and roots; and increasing sweet potato biomass.

Abstract

Artisanal gold miners usually dispose of gold mine tailings in storage ponds or agricultural land used for farming. However, the gold mine tailings still contain heavy metals such as cadmium, copper, lead, and zinc and can lead to bioaccumulation in food chains. This study investigated the influence of composted cow manure as organic fertilizer on heavy metals (Cd, Cu, Pb and Zn) content in sweet potatoes grown on soil contaminated by gold mine tailing. The MZ119 clone sweet potato plants were grown on soils added with mixtures of gold mine tailings at ratios of 0% (control), 30%, 50%, 70%, and 100% (w/w), and composted cow manure (0, 250, 500, and 750 g/10 kg of soil). The results showed that the higher the ratio of gold mine tailings to the soil, the higher the accumulation of metals in sweet potatoes. According to the translocation factor (TF) value, heavy metals (Cd, Cu, Pb and Zn) accumulated higher in the shoots than in the roots of sweet potatoes. Accumulation of heavy metals in sweet potato occurred in the following order: Zn>Cu>Pb>Cd. This study recommends that sweet potatoes could be used for the phytoremediation of heavy metals (Cd, Cu, Pb and Zn) in polluted soils, but the plants may not be used for consumption.

Abstract

Biofertilizers are recommended to improve crops yield but researches regarding biofertilizer inoculation on foxtail millet in Indonesia is still Tlimited. The objective of the experiment was to analyze the growth and yield responses of five local-millet accessions to Bacillus biofertilizer with reduced NPK fertilizer dose; and the germination rate of millet seeds. The pot experiment was arranged in randomized block design with 10 treatments and 10 replications. The treatments were combination of five millet accessions with one dose of NPK fertilizer, and half dose of NPK fertilizer with biofertilizer. Generally, half dose of NPK with Bacillus inoculation did not change the height of six-weeks old plant, and panicle weight and length of millet compared to one dose of NPK. However, this combined fertilizer increased plant height and panicle length of Mani-Mani 79. Reduced dose NPK with Bacillus inoculation increased panicles number of J3 but reduced that of Polman 3; moreover, this combined fertilizer increased the grain weight of J3 and J4, but decreased the yield of Polman 3. The Enrekang and Polman 3 accession had better germination rate; 92% and 89.33%, respectively. This research considered that Bacillus biofertilizer reduced NPK fertilizer dose by 50% and is suggested for growing millet.ABSTRAKPupuk hayati banyak disarankan untuk meningkatkan produksi tanaman tetapi riset mengenai inokulasi pupuk hayati pada jewawut aksesi lokal Indonesia belum banyak dilakukan. Percobaan ini bertujuan untuk menganalisis respons pertumbuhan dan hasil lima aksesi jewawut lokal terhadap inokulasi pupuk hayati Bacillus dan pengurangan dosis pupuk NPK; serta daya berkecambah biji jewawut setelah panen. Percobaan pot disusun dalam rancangan acak kelompok dengan 10 perlakuan dan 10 ulangan. Perlakuan percobaan adalah kombinasi lima aksesi jewawut dengan satu dosis pupuk NPK, dan setengah dosis pupuk NPK disertai pupuk hayati. Umumnya, tinggi tanaman umur enam minggu, serta bobot dan panjang malai jewawut dengan setengah dosis NPK disertai inokulasi Bacillus sama dengan tanaman yang diberi satu dosis NPK. Namun, tinggi tanaman dan panjang malai Mani-Mani 79 meningkat setelah aplikasi setengah dosis NPK dengan inokulasi Bacillus. Jumlah malai aksesi J3 meningkat sedangkan Polman 3 menurun dengan aplikasi setengah dosis NPK disertai inokulasi Bacillus. Kombinasi pupuk ini meningkatkan bobot biji J3 dan J4 tetapi  menurunkan hasil Polman 3. Aksesi Enrekang dan Polman 3 memiliki daya berkecambah yang lebih baik; masing-masing sebesar 92% dan 89,33%. Penelitian ini menunjukkan bahwa pupuk hayati Bacillus dapat mengurangi dosis pupuk NPK sampai 50% dan dapat disarakan untuk tanaman jewawut.

Abstract

The environment is one important factor that must be considered in supporting sweet potato productivity. Environmental factors can be biotic and abiotic, including the availability of nutrients and microbes in the soil. This study aims to identify the nutrient content of the soil in wetland and upland, identify the total invertase microorganisms in wetland and dupland, and identify the relationship between soil nutrients and microorganisms during the growth of Cilembu sweet potato in dry and wetland agroecosystems. This research was conducted on upland and wetland in Cilembu Village, Sumedang Regency. The experimental design used was a single randomized block design (RBD) with six treatments and three replications:  A; Rancing, wetland, B; Biang wetland, C; Mencrang wetland, D; Rancing, uplands, E; Biang, uplands, F; Mencrang, upland. Parameters observed included pH, C-organic, total-N, available-P, exchangeable K, exchangeable Na, exchangeable Ca and exchangeable Mg, CEC, and total invertase-producing bacteria. The results showed that in wetland nutrient content such as N, P, exchangeable Ca,  Mg, Na, CEC, C-organic and pH tended to be more available. K content and abundance of invertase bacteria are more available in upland. The availability of invertase bacteria has a close relationship with the K content. The information generated in this study can be used as a basis for determining an effective location to produce good quality.

Abstract

The meticulous harvesting process and appropriate post-harvest techniques play pivotal roles in preserving the quality and health benefits of white tea. This careful approach maintains the bioactive compounds such as polyphenols, caffeine, gallic acid, Epigallocationchin (EGC), Epigallocationchin gallate (EGCG), and Epicatechin gallate (ECG), integral to white tea's health benefits. The stability of catechin content in tea plants is greatly influenced by the environment (clone, plant age, leaf age, altitude, temperature, humidity, processing, and pH when storing dry tea). In Indonesia, the raw materials used to produce white tea are mostly pecco from the superior GMB clone Assamica variety which has high polyphenol content (14.83 – 15.43% dry weight). To increase polyphenol levels, the treatment that needs to be considered is the provision of optimum and appropriate fertilizer. The highest catechin content comes from plucking in summer and spring season. Subsequently, controlled post-harvest processes, including controlled withering and drying, safeguard the integrity of active compounds like catechins as antioxidants in white tea, mitigating free radicals and cellular damage.  The highest antioxidant showed from 23 hours whithered. The storage time for white tea also has an impact on quality. The content of catechins and amino acids showed a tendency to decrease with storage time. On the other hand, gallic acid increases with the length of storage. The combined effect of these phases, from harvesting through post-harvesting, contributes significantly to white tea's health benefits, encompassing cardioprotective effects, anti-diabetic potential, prevention of anticarcinogenic and antimutagenic activity, neuroprotective properties, and antimicrobial attributes.
