Food shortage has been among the most threatening problems to the world since the beginning of the new century. And it means more to the countries with a large amount of citizens such as China. Chinese governments at different levels have being taken different kinds of actions to stabilize and increase the yields of grains. A major premise of making right decisions is the ability to accurately ...

The agricultural sector will require more water in the near future to provide more food, fibre and fuels (Molden et al., 2007). As population increases and development calls for increased demand of food, a change in diet due to increased prosperity, and a recent focus on biofuels. This population growth coupled with industrialization and urbanization will result in an increasing demand for wate...

assessment of agricultural drought risk at critical times before and during the growing season can provide sufficient time to policy makers and farmers to implement appropriate strategies to reduce the potential of risk. the purpose followed in the present study is to develop a statistical model to estimate the quality of agricultural drought risk for rainfed barley crop (prior to planting and ...

Diseases caused by plant pathogens significantly reduce growth and yield in agricultural crop production. Raising immunity in crops is therefore a major aim in breeding programs. However, efforts to enhance immunity are challenged by the occurrence of growth inhibition triggered by immunity that can be as detrimental as diseases. In this review, we will propose molecular models to explain the i...

This study aimed at examining the merit of crop diversification as a strategy for agricultural growth in Bangladesh. Specifically, the existence of economies of diversification, scale economies and diversification efficiencies at the farm level were examined using a stochastic input-distance function approach. Results reveal strong evidence of diversification economies amongst most crop enterpr...

Indonesia sustained an average increase in agricultural output of 3.6% per year between 1961 and 2006, resulting in a more than fivefold increase in real output. This paper constructs Tornqvist-Thiel indices of agricultural outputs, inputs and total factor productivity (TFP) to examine the sources of growth in Indonesian agriculture over this period. The paper extends previous work on measuring...

Weather has a significant impact on crop growth and development. This paper presents an overview of crop modeling and applications of crop models, and the significance of weather related to these applications. To account for the impact of weather and climate variability on crop production, agrometeorological variables are one of the key inputs required for the operation of crop simulation model...

FOR MOST COUNTRIES, HIGH PRODUCTIVITY GROWTH IN THE AGRICULTURAL SECTOR HAS BEEN A KEY DRIVER of structural transformation promoting long-term economic growth. Historically, low agricultural productivity growth has hindered economic growth and employment creation in the Philippines, where agriculture—which accounts for one-third of employment—remains a key sector. Climate change has the potenti...

Patterns of crop diversification of modern agricultural technology, especially during the period of the Green Revolution in the late sixties and early seventies, there is a continuous surge for diversified agriculture in terms of crops, primarily on economic considerations. Indian agriculture is increasingly getting influenced more and more by economic factors. This need not be surprising becau...
