Coffee, black pepper, tea and fruit trees have been grown in the red soils (Rhodic Ferralsols – FRr). The study objectives aim at (1) assessing the organic fertilizer, N and P fertilizer application to soil fertility in case of coffee plantation in Di Linh, Lâm Đồng; (2) analyzing the fertilizer application to robusta coffee (Coffea canephora Pierre); (3) proposing a sustainable development of coffee farm under red soil condition.
The objectives aim at (1) identifying amino acid components among 25 popular materials for porcine feed-stuff industry in Vietnam; (2) identifying the digestion potential by the amino acids, which include in 25 materials; (3) identifying the industry demand to optimize the feed-stuff. The materials for starch and protein in animal feed-stuff included lower essential amino acids as lysine, threonine, methionine and tryptophan; with low CP of 16% and other essential amino acids exhibited lower than swine demand.
Study on mycotoxin has been conducted for more than 40 recent years as well as animal husbandry industry. The study aims at (1) evaluating the status and critical levels of DON and FUM, which contaminate maize and commercial feed stock for pig farms in southern Vietnam; (2) impacting to dietary with different amount of DON and FUM to perform commercial pigs; (3) assessing the effect absorbent substances using to treat contaminated feed or feedstuffs.
The study was conducted from 2011 to 2016 at Department of Genetics and Plant Breeding - Cuu Long Delta Rice Research Institute and five rice-producing provinces in the Mekong Delta viz. Long An, Hau Giang, Can Tho, An Giang and Tra Vinh. The study aims at (a) determining breeding materials to develop new genotypes adapted to heat tolerance due to climate change; (b) determining elite progenies from backsrossing populations via molecular markers-assisted selection with recurrent parent AS996 and donor N22.
Dendrobium Sonia (D. Sonia) is the cut-flower orchid commonly grown in Ho Chi Minh city. The study aims at to improve the fertilizer management to enhance Dendrobium Sonia obtaining more economic value. In particular, how (i) to determine the effect of P, Ca and boron B on growth and flowering;
The main purpose is characterization of Vietnamese wild rice to apply them as valuable genetic resources to improve cultivars. In the past, one of wild rice accessions has been used to breed superior variety AS996 which are cultivated in Vietnam and getting more cultivating areas. This thesis is composed from two parts, 1) Evaluation genetic resources in the Mekong delta, 2) Characterization of superior variety AS996 bred with a particular wild rice in Vietnam. 1
During 2014- 2016, farmers in Chau Thanh district, Tra Vinh province, Vietnam under financial support from Tra Vinh Department of Science and Technology, applying technical package and supervision of IAS and economic contract with Ecotiger Ltd company has been, produced, processed and exported organic rice following standard of EU, USDA and JAS to EU and America.
Phaeoacremonium parasiticum has been found to be associated with oleoresin deposition in Aquialaria malaccensis (Agar plant). Mass culture of P. parasiticum needs to be done for its economic and large scale production of Agarwood oil. P. parasiticum cultured on PDA petriplate at 30±1oC, showed very slow growth rate.
Dendrobium is a major orchid species growing in Vietnam farms. Two viruses CyMV (Cymbidium mosaic virus) and ORSV (Ondotoglossum rinspot virus) have become severe damages to orchids. However, the infection to Dendrobium by CyMV in Ho Chi Minh City offered 67.5% more severely than ORSV. Variety Sonia’ s PLDs were successfully transformed via Agrobacterium tumefaciens – mediated with strain C58 (EHẠ and LBA4404).
Shrimp value chain in Vietnam functions with a large number of farmers. They stay in the weakest position in the chain due to their small individual scale with an average land of about 0.5 ha/farm, and low skills (Ho, 2012). As a leader and holding the strongest power in the shrimp value chain, the processors determine shrimp prices and set up requirements of shrimp quality and size in the market though quality control has not been completely implemented due to the limitations of financial capital,
Value chain governance in the shrimp sector refers to the relationships among the primary and secondary actors namely input suppliers, farmers, collectors, processing plants and governmental institutions. Traditional governance type of the shrimp value chain in the early state (before the year 2004) showed the different levels of coordination of farmers with collectors, among collectors, and collectors with processing plants.
Straw mushroom sector has been strongly growing in Vietnam since last decade with more than 64,500 tons/year of production. The development of the sector helps improving both farm household’s income and the environment by reducing pollution from rice straw burning at the end of the rice cultivation season.
