A seven fold increase in the rate of respiratory O2 uptake was observed 24 h after slicing of potato tuber disks. The maximum activity of pyrophosphate:fructose-6-phosphate phosphotransferase (PFP) was 5-7 times greater than that of ATP-dependent phosphofructokinase (PFK) in fresh or aged potato slices. Thus, PFP may participate in glycolysis which supplies respiratory substrate in potato tuber...

The use of dry land for shallot cultivation in Indonesia is still not optimal because it considered as that has no good potential crop cultivation. Dry problems include limited availability water, low organic matter and soil nutrients, especially potassium. purpose this experiment was to determine the response vermicompost KNO3 fertilizer growth yield shallots on land. experimental design used ...

Various physical and chemical properties of host plants influence insect larval performance and subsequent adult fitness. Tomato plants are relatively new hosts to the potato tuber moth, Phthorimaea operculella (Zeller), with the fruit being its preferred feeding site. However, it is unclear how the biochemical and physical properties of tomato fruits relate to potato tuber moth performance. Si...

Potato tuber is a high yielding food crop known for its high levels of starch accumulation but only negligible levels of triacylglycerol (TAG). In this study, we evaluated the potential for lipid production in potato tubers by simultaneously introducing three transgenes, including WRINKLED 1 (WRI1), DIACYLGLYCEROL ACYLTRANSFERASE 1 (DGAT1) and OLEOSIN under the transcriptional control of tuber-...

Experiments were conducted to study the plant growth and tuber yield of the seed potato collected from PVY and PLRV infected plants. The seed potatoes were graded as under size (<28 mm), A grade ( 28-40 mm), B grade (41-55 mm) and over size (>55 mm) which were planted following RCBD in the field. Third generation seed potatoes of Diamant variety were used. The incidence of viruses was confirmed...

This research aims to know the agronomic character and resistance of shallots against fusarium wilt disease under various salicylic acid treatments. was conducted in a greenhouse using completely randomized design with one factor, namely treatment concentrations (0 ppm, 15 20 25 ppm) 3 replications. Each inoculated Fusarium acutatum inoculum (106 conidia ml-1 distilled water) except for negativ...

Shallot production in Central Sulawesi recorded a decline from 8.651-8.362 tons, between 2017-2018. However, the use of an accurate composition planting medium serves as possible alternative to boost yield. Also, introduction organic matter tends increase nutrient content, influence aeration, and subsequently leads drainage. This study is aimed at determining effect plant media on shallot growt...

Abstract Waxy cassava having high amylopectin content could contribute and increase genetic background. Unfortunately, the parameter information of three elite clones as Waxy, UJ-5, BW-1 is still limited. Consequently, objective this study was to evaluate leaf weight yield by correlation path analysis clones. This conducted on Integrated Field Lab Lampung from December 2019 October 2020. Treatm...

Abstract Japanese taro (Colocasia esculenta var. antiquorum) production in Indonesia is around 20 tons/hectare, but it still relatively low due to the level of farmer management including fertilizing and watering especially dry season. We determined effect plastic mulch biofertilizer on growth japanese plants. This research used a split plot design. The main was consist two levels, namely contr...

Soil-incorporated rotation/green manure crops were evaluated for management of potato early dying caused by Verticillium dahliae and Pratylenchus penetrans. After two years of rotation/green manure and a subsequent potato crop, P. penetrans numbers were less after 'Saia' oat/'Polynema' marigold, 'Triple S' sorghum-sudangrass, or 'Garry' oat than 'Superior' potato or 'Humus' rapeseed. The area u...
