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...

Maximum potato (Solanum tuberosum L.) tuber yields occur when an active plant canopy is maintained until normal plant maturation. Plaid nutrient concentrations and uptake rates play a major role in maintaining an active plant top. The objectives of this study were to relate the plant P concentrations to the P and dry matter balance between tuber and total plant growth needs. Growth analysis dat...

This study examined the effects of season-long exposure to elevated carbon dioxide (CO2) and/or ozone (O3) on tuber quality in potato (Solanum tuberosum L. cv. ‘Bintje’). Stands of potato were grown to maturity in open-top chambers (OTCs) in 1998 and 1999 under a factorial combination of three CO2 (ambient, 550 and 680 mol mol−1) and two O3 levels (ambient and elevated; 8 h per day seasonal mea...

Rapid wound-healing is crucial in protecting potato tubers from infection and dehydration. Wound-induced suberization and the accumulation of hydrophobic barriers to reduce water vapour conductance/loss are principal protective wound-healing processes. However, little is known about the cognate mechanisms that effect or regulate these processes. The objective of this research was to determine t...

in order to study of yield and qualitative characteristics of potato (aola variety), an experiment was conducted in mashhad conditions under irrigation regims and different levels of potassium fertilizer. this experiment was based on randomized copmpletely block with split plot design with three replications in khorasan razavi agricultural and natural resource research center in 2010. three lev...

The production of shallots can still be increased through technical improvements in cultivation, such as the application organic fertilizers and eruption Mount Merapi (volcanic ash). Organic have a significant role improving chemical biological properties soil do not negative impact on environment, although nutrient content manure is high that artificial fertilizers. This study aims to determin...

The uptake and distribution of Cd in potatoes over the course of a growing season was investigated in two cultivars of potatoes that differed in tuber Cd concentration. Plants were grown in soil with supplemental Cd. The concentrations of Cd in different tissues varied greatly in the order roots>shoots>> tubers. After the initiation of tuber bulking, shoot growth ceased and the increase in tota...

Methods to identify Pinelliae Tuber and Arisaematis Rhizoma are required because of frequent reciprocal substitution between these two herbal medicines and the existence of several closely related plant materials. As a result of the morphological similarity of dried tubers, correct discrimination of authentic herbal medicines is difficult by conventional methods. Therefore, we analyzed DNA barc...

Potato late blight, caused by the oomycete phytopathogen Phytophthora infestans, is a devastating disease found in potato-growing regions worldwide. Long-term management strategies to control late blight include the incorporation of host resistance to predominant strains. However, due to rapid genetic changes within pathogen populations, rapid and recurring identification and integration of nov...
