In Vietnam, esp. In the northwest region, tea and coffee crops have been increasing in both quality and quantity and scientists are trying to find ways to increase productivity, as well as eliminate damaging insects and coffee berry borer, etc in order to reduce damages for farmers. The fact in agriculture is that when farmers are in good crops, the coffee price is going down and vice versa. In our last paper, we have mentioned coffee berry borer, and until this paper, we will explore new issues of increasing productivity, quality and quantity for both tea and coffee crops in Vietnam, esp. in the northwest area. Among results is relating to coffee seeds and technique planting of farmers with suitable land area and the solutions and ways for farmers to earn profits after they invest into coffee and tea crops. Our paper can be foundations for suggesting and setting agriculture development policies as well. For instance, we recommend that Completing the equivalent system of food hygiene and safety regulations/standards market in developed countries. Additional regulations on safety inspection and supervision food straight from the field. Last but not least, we proposed marketing solutions for farmers to expand exporting markets to other countries.

Fungus Beauveria Bassiana

Among important crops in Vietnam, we have to mention the coffee crop as the main cultivated crop in northwest area of the country, then we have to deal with the negative factor, or insect, coffee berry borer (CBB), which cause losses and damages for farmers with negatively significant impact. In previous studies, we isolated and identified five Beauveria bassiana strains of entomopathogenic fungus that damaged on coffee berry borer in local coffee fields of Son La province, Vietnam. The objective of this study continued to choose one of them for management CBB by autoinoculation trap. The result show that the virulence against CBB of the Bb5(MCB1) strain was highest (71.3 % confirmed mortality). Although 62.5% of CBB females that exposed to the Bb5(MCB1) fungus product with an average of 0,47 x 1012 conidia.gram-1 were able to penetrate the coffee berry exocarp, only 3.7% reached the endosperm. An autoinoculation trap containing the entomopathogenic fungus Bb was designed for the management of the CBB (trap TBU-AIT). Traps TBU-AIT baited with methanol and ethanol (1:1 ratio) mixtures at 868 mg day-1 attracted more insects than those traps baited at 452, 715 and 1050 mg day-1. We found a statistically-significant difference in average confirmed mortalities by fungus and by different field conditions in the period between 0 - 63 days setting traps TBU-AIT. Altogether, these results and relatively low production costs these auto-infection system can be recommended for integrated pest management on coffee auto-infection trap.

Physical Capital Accumulation

This paper discusses the relation between the quality and quantity indicators of physical capital and modernisation. While international academic literature emphasises the role of intangible factors enabling technology generation and absorption rather than that of physical capital accumulation, this paper argues that the quantity and quality of physical capital are important modernisation factors, particularly in the case of small, undercapitalised countries that recently integrated into the world economy. The paper shows that in Hungary, as opposed to developed countries, the technological upgrading of capital assets was not necessarily accompanied by the upgrading of human capital i.e. the thesis of capital skill complementarity did not apply to the first decade of transformation and capital accumulation in Hungary. Finally, the paper shows that there are large differences between the average technological levels of individual industries. The dualism of the Hungarian economy, which is also manifest in terms of differences in the size of individual industries' technological gaps, is a disadvantage from the point of view of competitiveness. The increasing differences in the size of the technological gaps can be explained not only with industry-specific factors, but also with the weakness of technology and regional development policies, as well as with institutional deficiencies.

Land Saving

During the last few decades there has been a sharp transition in economic doctrine, within the context of economic growth, on the relative contributions of agriculture and industrial development. There has been a shift away from the earlier 'industrial fundamentalism' to an emphasis on the significance of growth in agricultural productivity and production. The focus, especially in the context of the present-day less developed countries like Pakistan, has sharpened with the rapid growth in demand for food, resulting from the increasing growth in population and the high income-elasticities of the demand for food. Coupled with this is the transition from resource-based agriculture to science-based agriculture. Agricultural economists are unanimous in the view that by the end of this century all increases in world food production will come from higher yields, i.e. increased output per hectare. This increasing emphasis on 'land-saving' technology to increase productivity and production has resuited from the growing population pressures on land and declining land-man ratios. Agricultural research has come to the fore in providing technologies that increase productivity and production. However, these technologies do not explicitly take into account the equity aspects of the problem. The extent to which the poor gain or lose from the introduction of a new agricultural technology depends on a host of complex and interrelated socio-economic and political factors such as the existing distribution of productive resources, access to modem inputs, the structure of the market, etc.

Coffee Yield

Coffee agroforestry systems could reconcile agricultural and environmental objectives. While pests and diseases can reduce yield, their interactions with shade and nutrition have been rarely researched, and are particularly lacking in perennial systems. We hypothesized that intermediate shade levels could reduce coffee pests while excess shade could favor fungal diseases. We hypothesized that organic rather than mineral fertilization would better synchronize with nutrient uptake and higher nutrient inputs would be associated with reduced pest and disease damage due to higher plant vigor, yet effects would be less obvious in shaded plots as coffee growth would be light-limited. Using three-year-old trees of Coffea canephora var. Robusta (robusta coffee) in the Ecuadorian Amazon, we compared a full-sun system with four shading methods creating different shade levels: (1) Myroxylon balsamum; (2) Inga edulis; (3) Erythrina spp.; or, (4) Erythrina spp. plus Myroxylon balsamum. Conventional farming at either (1) moderate or (2) intensified input and organic farming at (3) low or (4) intensified input were compared in a split-plot design with shade as the main plot factor and farming practice as the sub-plot factor. The infestation of the following pests and disease incidences were evaluated monthly during the dry season: brown twig beetle (Xylosandrus morigerus), coffee leaf miner (Leucoptera coffeella), coffee berry borer (Hypothenemus hampei), anthracnose disease (Colletotrichum spp.), thread blight (Pellicularia koleroga), and cercospora leaf spot (Cercospora coffeicola). Coffee berry borer and brown twig beetle infestation were both reduced by 7% in intensified organic treatments compared to intensified conventional treatments. Colonization of coffee berry borer holes in coffee berries by the entomopathogenic fungus Beauveria bassiana was also assessed. Brown twig beetle infestation was significantly higher under full sun than under Inga edulis, yet no other shade effects were detected. We demonstrate for the first time how intensified input use might promote pest populations and thus ultimately lead to robusta coffee yield losses.
