Technological innovations will leads to meet the present and future challenges of agriculture sector. Water is one important natural resource, since time immemorial, also acted as catalyst during Green Revolution helped India achieve self-sufficient status in food grain production. Fresh water only 2.6% total resources world has be utilized efficiently. Inspite coverage under irrigation phenome...

In this study was examined the factors affecting the unwillingness to adopt pressurized irrigation methods among farmers' groups (with different levels of drought) in Ardabil province (Iran). Mixed method (Qualitative – Quantitative paradigm) was used for doing this research. First, by drought zoning of Ardabil province (by SPI method and GIS), three regions included the mild, moderate and seve...

Field water balance measurements using monolithic lysimeters were used in validating the Cupid-DPE model for predicting water loss partitioning during sprinkler irrigation from a moving lateral system fitted with impact sprinklers and spray nozzles. The model combines equations governing water droplet evaporation and droplet ballistics with a comprehensive plant-environment energy balance model...

limited water resources, especially in iran, require most effective method of water use to avoid losses. one of the important parameters in irrigation is water distribution uniformity coefficient (cu) in sprinkler irrigation. cu in every irrigation depends on pressure heads (p), riser height (rh), distance between sprinklers on lateral pipes (sl), and the distance between lateral pipes (sm). th...

Monitoring of diamondback moth (Plutella xylostella L) population on cabbage and Chinese cabbage over the past eight years has indicated that heavy rains from June to September limit the population of the insect. Therefore, during the dry period when diamondback moth is a serious pest, water was applied by sprinkler system placed 1.5 m over the cabbage crop rather than by traditional furrow irr...

The article presents the results of research on effect sprinkling structural and aggregate composition soil its density. high quality irrigation is achieved with uniform distribution rain over area, acceptable intensity drop diameter impact force, at which plants structure are not damaged, puddles surface runoff formed. For complete absorption water into preservation low intensity, small drops ...
