Food loss and waste generation are also the major inefficiencies in the food processing sector. Bolting was not influenced by sowing time, but by the volume of the root zone during cultivation in the high temperature season.
Introduction
BUDDING AND FLOWERING OF Delphinium grandiflorum IS NOT AFFECTED BY THE TIME OF PLANTING BUT THE VOLUME OF THE ROOT AREA. In this experiment, the effects of seedling growth period and root area volume on growth, flowering and cut flower characteristics in 'F1 Morpho Grand Blue' were investigated.
Material and methods
In a preliminary experiment, when 'F1 Morpho Platinum Blue' sown in a 406-cell tray with root zone volume of 4 ml was continued to grow in the cell, it did not bolt at all, even at high temperatures in the summer and even beyond autumn. There is a possible production that high quality cut flowers can be done. 2022) reported that 'F1 Morpho Platinum Blue' and 'F1 Morpho Grand Blue' grown in 406-cell trays could prevent early bolting.

Conclusion
In 'Nessho', flower color is also affected by the expression level of DvFNS in the whole plant (Okada et al., 2018). In the cultivar dahlia 'Nessho', there is also a correlation between DvFNS gene expression levels in young, unexpanded leaves and flower color expression (Okada et al., 2018).
Materials and Methods 1. Plant materials
- Classification of plants
- Induction of DvFNS expression
- Total RNA extraction and real-time qPCR
- Statistical analysis
We compared DvFNS gene expression in young unexpanded leaves of relatively low-susceptible and relatively high-susceptible plants before and after treatment with DvFNS gene-inductive conditions. Eight candidate plant strains with relatively low sensitivity (CRL1, CRL2, CRL3CRL4, CRL5, CRL6, CRL7, and CRL8) and one highly sensitive CRH strain were used in subsequent experiments for analysis of DvFNS gene expression.
Results and Discussions
In petunia, gene expression for CHS is increased by exposure to low temperatures (Shvarts et al., 1997). African swine fever (ASF) is an acute infectious disease caused by African swine fever virus (ASFV), genus Asfivirus, family Asfarividae (Dixon et al., 2013).
The infection and spread of ASFV in Vietnam
This study aimed to provide a general picture of the clinical symptoms, lesions and risk factors of ASF in the complex epidemiological context of Vietnam. In addition, we used the references from Vietnamese journals, including Journal of Veterinary Science and Technology, Vietnam Journal of Agricultural Sciences, and Can Tho University Journal of Science.
The risk factors of ASF in Vietnam
Farms using river water had a 1.67 times higher risk of disease than farms using well water (Nguyen et al., 2020). Farms near burial sites had a much higher risk of disease than others (Vo et al., 2021).
Clinical signs and lesions of ASF in Vietnam
In some cases, the lymph nodes swell up large and dark, similar to a blood clot (Nguyen et al., 2020). The spleen of pigs infected with AFSV shows signs of infarction that make it enlarged and fragile (Tran et al., 2021).
Conclusion
Clinical and pathological investigation of the first outbreak cases of African swine fever in Vietnam, 2019. The future of the pig industry after the introduction of African swine fever in Asia.
MATERIALS AND METHODS 1. General structure of the study
- Establishing the set of questions for biosecurity assessment
- Building the software Pighealth Security-X
- Evaluating the reliability of scores by applying the App in the file of pig farms To evaluate the reliability of scores given by Pighealth SecurityX software in the field, a survey
- Data analysis
The traditional approach involved eight aspects of biosafety assessment, including location and structure; Livestock farming practice;. In breeding sow farms with suckling piglets, sows and boars, the maximum disease score was 85; at fattening pig farms the maximum disease score was 50.
RESULTS
The questionnaire for the App Pighealth Security-X
For suckling piglets, weaned pigs, growing pigs and boars, the maximum number of disease points for each group of pigs was 25 points. On-farm disease incidence results were converted to a percentage (%) by dividing the total number of diseases on the farm by the maximum number of diseases and multiplying by 100%.
Building the software Pighealth Security-X
In detail, large farms had a higher score in all eight aspects with a statistical difference (P<0.05). In the modern approach, large-scale farms had a higher biosecurity score in all aspects (P<0.05).
DISCUSSION
Respiratory and gastrointestinal failure contributed significantly to disease status in study farms, especially on medium-sized farms. The study also found that large farms had a higher biosecurity score in all eight aspects of biosecurity compared to medium-sized farms.
CONCLUSIONS
EFFICIENCY OF WATER USE FOR IRRIGATION OF WET RICE CULTIVATION UNDER CLIMATE CHANGE IN PHU THIEN DISTRICT, GIA LAI PROVINCE. Keywords: AquaCrop, CropWat, climate change, irrigation water use efficiency, alternating flooding and drying.
Materials and Methods 1. Study area
Data collection 1. Climate
- Crop
- Soil
In Phu Thien district, paddy rice is grown in spring and summer-autumn crops, which is alternately wetted and dried during floods. The Kc of wet rice in CropWat was calibrated based on Vietnam National Standard TCVN 8641-2011 for irrigation water.
AquaCrop model
Results and Discussions 1. Irrigation requirement
Rice yield
Thus, the average rice yield reached 4.61 tons/ha in the base scenario and decreased significantly with climate humidity. The reason is that higher temperature promotes higher evaporation leading to increased evaporation and reduced rice yield.
Irrigation Water Use Efficiency
The impact of three climate change scenarios compared to the baseline scenario on rice yield on three soil textural classes and two crops in Phu Thien district is shown in Figure 3. The impact of salt and fertilizer concentrations on rice yield is not taken into account in the AquaCrop model.

Convolutional Neural Network
The SoftMax function is a function that converts a vector of n values to a vector of n values that sums to 1. The final fully connected layer's output is generally equivalent to the layer to be identified.
The architecture of the AlexNet model
As a result, image details are preserved while the image size is drastically reduced (Krizhevsky, A., Sutskever, I., 2012; Zeiler & Fergus, 2014). The SoftMax function is used as the activation function in a final layer to normalize the outputs, each output value is interpreted as the probability of each class (Chen et al., 2022).
The architecture of the ZFNet model
Research Methods 1. Collecting data
- Introducing datasets
- Data collection methods
- Request picture samples
- Proposed model
The pictures of some plants' leaves were taken with the leaves still on the plant (without clipping the leaves), as cutting the leaves causes leaf curling, which leads to image degradation. This is the most suitable time for sampling because the sunshine is at its peak and the standing water on the leaves has evaporated.
Based on the AlexNet and ZFNet models, we proposed a model with eleven layers (excluding the input data layer) with four convolution layers, four maximum-pooling layers and three fully connected layers, as shown in Figure 9. We have more than a max pool layer and less than a convolution layer and changed the order of layers.
Convolution of 96 filters, size 7 x 7, stride 2, padding 3
Experimental results
The proposed model requires 1.82 MB of memory for each image and has 33 million parameters, significantly lower than AlexNet and ZFNet's 60 million. The number of generated parameters is reduced, resulting in a lower complexity of the proposed model and a reduction in training time.

In the agricultural sector, the factors influencing the choice of marketing channels also differ significantly. Empirical studies on factors influencing farmers' choice of marketing channels mainly focus on demographic factors (age, gender, experience, education, household size); agricultural factors (farm size, production, location, membership, access to information, off-farm work), transaction-specific factors (price, transportation costs, payment, channel offers) and relationship dynamic factors (trust, personal relationships, power and negotiation).
