International trade and agricultural productivity: Evidences from least developed countriesFrom the development perspective, our paper raises the issue that expanding trade does not necessarily provide a favourable background for improvement in the agriculture sector in LDCs. Governments, therefore, should be aware of the impacts of trade negotiation not focusing only on trade values. It should also be noted that the high protecti...

Isolation and identification of an actinomycete strain with biocontrol effect against Xanthomonas oryzae pv. oryzae causing bacterial blight disease in riceTwo actinomycete strains which expressed antagonistic activity against Xanthomonas oryzae pv. oryzae causing bacterial leaf blight were selected. Among them, the strain 43 showed stronger activity with 22 mm in diameter of clear zone. The biological characteristics of the actinomycete strain 43, such as morphology, culture, physiology and b...

Simulating yield response of maize to climate change with aquacrop model in Northwest VietnamClimate change scenario B2 was used to predict the impact of climate change for the period of 2013 - 2100. The AquaCrop model, after calibration, was applied to simulate the yield of maize under climate change conditions. The results are shown in Table 3. Figure 3 indicates a slightly increasing trend of maize yield for climate change scenar...

Effects of irrigation methods on the growth, yield and water use efficiency of tomatoes in Red river delta alluvial soilDrip irrigation increased the tomato fruiting rate in comparison with furrow irrigation but unevenly. The drip irrigation treatment with 70 - 100% βdr (T4) had the highest fruiting rate of 71.3%, 7.3% higher than furrow irrigation, and the fruiting rate of the drip irrigation treatment of 60 - 100% βdr (T3) was also higher than that of furro...
