The bacterium 'Dickeya solani', an aggressive biovar 3 variant of Dickeya dianthicola, causes rotting and blackleg in potato. To control this pathogen using bacteriophage therapy, we isolated and characterized two closely related and specific bacteriophages, vB_DsoM_LIMEstone1 and vB_DsoM_LIMEstone2. The LIMEstone phages have a T4-related genome organization and share DNA similarity with Salmon...

Vegetative propagation of potato allows the dissemination of viruses that can cause drastic drops in tuber yield. Potato virus Y (PVY) is one of the most important viruses of potato due to the non-persistent mode of transmission through vector insects. Genetic resistance is the recommended control measure since the chemical control of vector insects is not effective. This study aimed to identif...

Potato is one of the most important crops worldwide. Its commercial cultivars are highly susceptible to many fungal and bacterial diseases. Among these, bacterial wilt caused by Ralstonia solanacearum causes significant yield loss. In the present study, integrated proteomics and genomics approaches were used in order to identify bacterial wilt resistant genes from Rs resistance potato cultivar ...

potato is one of the sensitive plants to drought stress and it is one of the main crops in the north regions of fars province. since the planting time is simultaneous with wheat irrigation period, due consideration should be given to reduce irrigation consumption for this crop. this research investigated the effect of potassium sulfate on the drought tolerance of potatoes. field experiment was ...

Currently the world is moving towards organic production of crops for the discovered and envisaged advantages. Despite this, farmers are faced with the challenges of the bulkiness of organic fertilizer to be used and further gains that could be accrued from it even if sacrifice of using it is made. To be quite sure of the appropriate fertilizer type to be used in improving quality as well as th...

the aim of this study was to examine potato growers' perceptions of risk sources and risk management strategies and their risk management behavior. a survey research method was used in this study. the data originated from a sample of potato growers (n= 128) of ardabil province in the cropping year of 2013. the respondents were divided into two groups of less risk-averse (lra) and more risk-aver...

Accurate predictions of crop yield are critical for developing effective agricultural and food policies at the regional and global scales. We evaluated a machine-learning method, Random Forests (RF), for its ability to predict crop yield responses to climate and biophysical variables at global and regional scales in wheat, maize, and potato in comparison with multiple linear regressions (MLR) s...

Hortic. bras., v. 22, n. 2, abr.-jun. 2004 C potato (Solanum tuberosum L.) is one of the most important vegetable crop of Brazil and the world’s fourth most important crop (Solomon-Blackbourn & Barker, 2001). In 2002, Brazil produced 3,126,411 t of potato with an average yield of 19,4 kg/ ha (IBGE, 2002). Potato is a tetraploid species and the use of its botanical seeds in commercial cultivatio...

Effects of oxidative browning inhibitors on sweet potato protein (SPP) recovery and quality were studied. Oxidative browning inhibitors successfully decreased sweet potato oxidative browning, but reduced both SPP extractability and recovery. Ultrafiltration/diafiltration processed sweet potato (UDSP) protein (at pH 4, 6 and 7) showed significantly (p<0.05) higher yield, purity, solubility, ther...

Chemical marker M-2 (4-hydroxy-5-methyl-3(2H)-furanone) can be used as a tool to evaluate heating patterns of foods in microwave sterilization. This research studied the kinetics of the M-2 formation in mashed potato as influenced by temperature and salt content. Mashed potato (83.12% moisture content) with 1.5% D-ribose was heated in the capillary tubes at four temperature levels. Chemical mar...
