A double cropping system has been commercially adopted in southern China, where there is abundant sunshine and heat resources. In this viticulture system, the first growing season normally starts as a summer cropping cycle; then, the vine is pruned and forced, resulting in a second crop in winter. Due to climate differences between the summer and winter growing seasons, grape ripening progressi...

The designs of Water distribution systems are based on certain objectives such as equity, adequacy to access its efficacy. The design of canal systems for distributing the water is based on the size of command areas. Duration of operation. It is a fact that Odisha is a predominantly agrarian state as more than 2/3rd of the state population depends on agriculture. Irrigation is the paramount imp...

The multiple cropping practice is essential to agriculture because it has been shown to significantly increase the grain yield and promote agricultural economic development. In this study, potential multiple cropping systems in China are calculated based on meteorological observation data by using the Agricultural Ecology Zone (AEZ) model. Following this, the changes in the potential cropping s...

Green Revolution triggered in India with the introduction of high yielding varieties of crops particularly wheat and rice in seventies. The cultivators rapidly adopted these varieties in states like Punjab, Haryana and Western Uttar Pradesh in North India, which produced high yields by greatly responding to modern inputs, generation of suitable crop production and protection technologies and fa...

one of the core elements of water management and increase agricultural productivity is the efficient use of available resources. due to increasing demand for agricultural products, increase the productivity of scarce resources is essential. optimal utilization of these resources, in addition to meet the demand of the community as a major goal, can also increase operating income to be followed. ...

ABSTRACT- Inadequate water supply is the major problem for agriculture in arid and semi-arid regions. Thus, effective management should be considered for water resources planning. In this research, a model was provided which is able to estimate optimal land and water allocation in the Doroodzan irrigation network. Optimal water management model was used at farm level to evaluate different defic...

A mathematical programming model is proposed for optimal cropping patterns under water de®cits in dry regions. Crops may be deliberately under-irrigated in order to increase the total irrigated area and possibly the pro®t. An operating policy will identify both the total area and the irrigation level allocated to a given selected crop taking into account the possible successors and predecessors...

introduction: the appropriate-use optimization of the limited spaces of the iranian hospitals is believed to be a crucial step towards promoting the efficiency of these healthcare centers. the issue determining the optimization patterns of the layout of units has led to a lot of efforts by researchers as it increases the efficiency of the hospitals through patients’ improvement, changing the lo...
