Abstract: This research focuses on various aspects of the constraints that farmers experience when producing vegetables. An attempt was made to describe selected characteristics of vegetable producers in the research region and to investigate the relationship with the constraints they experience. Data were gathered at random from vegetable producers from several places in Chapainawabganj by a properly structured interview schedule. The findings reveal that in terms of overall constraints most of the

farmers (90.5%) encountered medium constraints in vegetable cultivation. Based on the constraint facing index (CFI) input constraints affect the production of vegetables more than any other. The highest amount of land rent was obtained at the 1st rank among the input constraints. Lack of a suitable cold storage system holds the first position in case of technical constraints, and the higher price fluctuation of vegetables scored highest among the constraints in the marketing of vegetables. The technical constraints also had a great impact on the production of vegetables in the study area. High land rent, lack of suitable cold storage, and high cost of cold storage were scored above 100 out of a total score of 126 according to the CFI index.

Abstract: A data set of 140 selected rice varieties from regional registration testing in the Mekong delta published from 2018 to 2020 with four rice registering groups was studied for quality properties and the correlation between each quality parameter and comprehensive taste quality in this paper.. The differences in rice quality among four registering groups and three taste categories were identified. (1) Three groups of A0, A1, and A2 could be divided into fairly good and medium taste categories

only whereas the aromatic group could be divided into three taste categories. (2) In A0, A1 and A2 groups, the amylose content of the fairly good taste category was lower than that of medium taste category in three groups, by 5.91%, 4.38% and 6.38% respectively (P<0.05). However, the gel consistency of fairly good taste category was higher than that of medium one, by 25.79mm, 16.53mm and 26.66mm respectively. (3) In the aromatic group, the hulling percentage and milling percentage of good taste category were lower than that of medium one, by 2.65% and 2.47% respectively. The grain length, length/width ratio, smell and taste of high taste quality category rice were higher than those of medium taste category rice, by 1.04mm, 1.3, 1.72 and 0.79 respectively, however, the amylose content was non-significantly different among three taste quality categories (P<0.05). (4) The smell and tenderness were found highly positive correlation to comprehensive taste quality but amylose content was highly negative correlated to comprehensive taste quality in all groups (P<0.01).

Abstract: This study aimed to estimate allelic and genotypic frequencies of single nucleotide polymorphisms (SNPs) of MC4R (melanocortin-4-receptor gene) and PIT1 (pituitary specific transcription factor-1) genes, their additive dominance genetic effects on production and carcass traits in Duroc pigs. A total of 2170 tail tissue samples (1728 gilts and 442 male pigs) were collected at Dabaco Nucleus Breeding Pig Company, Bac Ninh province, Vietnam from January 2017 to June 2020. The polymorphisms in MC4R

and PIT1 genes were detected using the PCR-RFLP method. For MC4R, the frequencies of alleles A and G were 0.430 and 0.570, respectively. The frequencies of alleles A and B were 0.460 and 0.540 respectively for PIT1. The genotype frequency of the MC4R gene was in Hardy-Weinberg equilibrium (P=0.375), while not for PIT1 (P <0.001). MC4R and PIT1 polymorphisms were significantly associated with final body weight and average daily gain (P<0.001). Significant additive effects were also found (P<0.05) for the two traits. The selection of individuals with MC4R genotype AA and PIT1 genotype AA could improve final body weight and average daily gain.

Measures Used for Water Quality Management in Intensive Pangasius Catfish Production in Vietnam’s Mekong Delta: An Experience from Household Practice and Gender Role

Measures Used for Water Quality Management in Intensive Pangasius Catfish Production in Vietnam’s Mekong Delta

Abstract: Intensive aquaculture on a household-scale in Vietnam’s Mekong Delta region often decreases the quality of the water. The consequence is a negative effect on the yield of Pangasius catfish, which in turn reduces the income generation potential. Water quality management has become an important consideration, not only for sustaining livelihoods from household-scale aquaculture but also for mitigating the impacts on the surrounding water bodies. The purposes of this paper are to identify

strategies for improving water quality management in households practicing aquaculture and to understand the gender role in water management in the Mekong Delta. The effectiveness of existing household approaches to water quality management was found through analyzing data gathered through interviews. The primary data consists of interviews with 32 operators of different household-scale aquaculture systems. It was found that in 46% of these households, water quality had declined over the last three years. Several causes were identified including the accumulation of chemical and antibiotics residues, excessive stocking rates, and a lack of a system for water treatment. Several strategies to better manage water quality in these ponds have been identified including: changing the clean water more frequently, removing sediment after each harvest, planting trees around ponds, and applying lime to the base of the pond, or using potassium permanganate for disinfection before use. Although many water quality management approaches are in use by households, more than 90% of these activities are implemented by men.

Abstract: Small and Medium Enterprises, at over 90% of total enterprises, play the important role in economic development not only in Hanoi but also whole of Vietnam country. As an effective tool in business management, accounting supplies the important information for making decisions. Recently, information technology in business, especially in accounting works or e-accounting, has increased to take the advantages as much as possible and been considered making the change of accountants’ role in

business. In order to show the evidences of these changes for being the background of issuing solutions to improve the information technology application in accounting area of enterprises, this study conducted a survey of 186 small and medium-sized enterprises in Hanoi. The research results showed that the knowledge of current accounting staffs is one of two most obstacles to improve application of information technology or develop E-accounting in accounting areas of small and medium-sized enterprises. Almost enterprises accepted the positive features of information technology for accounting work, whereas they still strongly consider about the dynamic as well as satisfaction of specific information technology products in the accounting work, especially in appearing the new business transactions
