Drought stress that causes a significant reduction in maize productitivity, addresses the unpreditable forecast on incidence, severity level and occurrence frequences. Therefore, drought tolerance breeding on maize hybrids has always become an interest subject to be discussed. Otherwise, planting density and fertilizer levels are considered as the key factors to mainly affect maize productivity. Optimum planting density and appropriaate fertilizer application are essential to offer desirable grain yield.

Thirty-three potato clones were evaluated for resistance to the common scab disease of potato caused by Streptomyces scabies by artificial inoculation under greenhouse conditions at Dalat.

Study on controlling Ralstonia solanacearum bacterium disease of gourp crop by grafted technicque was conducted in Tra Vinh province anh Ho Chi Minh city from October 2010 to June 2012

The objectives of study were to determine some limitation factors on yield of bottle gourd and to find out one  -  two  cucurbit  rootstocks which might highly compatible with bottle gourd plant; high quality and main diseases tolerance. The study was included one survey and two experiments.

 Hepatocellular carcinoma (HCC) is the most common primary cancer of the liver, accounting for 70% - 85% of liver cancer cases. HCC has the leading incidence and mortality rate of cancer diseases in general. All most HCC cases were detected in late stage and patients have little chance of effective treatments. Recently, the use of microRNA molecules as potential markers has been focused on the diagnosis of HCC cases and other cancer diseases.

The study conducted from December 2011 to June 2012, the approach is to apply theory ” ValueLinks” (2007) – Eschborn - GTZ (Deutsche Gesellchaft für Technische Zusammenarbeit-Đức) and ”Market for  the Poor – Tool of value chain analysis” -  M4P (2007).

SSR  genotyping was  combined with selective genotyping to map quantitative trait loci (QTLs) associated with drought tolerance in rice. A total of 229lines (BC2F2) derived from the cross of OM1490/WAB880-1-38-18-20-P1-HB was evaluated for drought at flowering (DRF), root dry weight (RDW)

The study showed that capacity of rice milling plants ranged from 30 tons to 500 tons per day, average of 170.2 tons/day. There were 20% millers operated over ideal capacity / year, from 130 – 141%. However, almost millers (80%) operated below ideal capacity/year. The paddy inputs among millers were ranged from 6 tons to 500 tons/day, average with 136 tons/day.

The study on rice production and marketing via survey showed that farmers in Mekong had 0.5 ha, 2.2 ha and 6.5 ha for minimum, average and maximum farm size per household, respectively. 100% households carried out their rice production in winter- spring (Dong Xuan-DX) and summer- autumn (He Thu- HT) seasons
