A research was conducted in Southern Italy to study the changes in seed yield, oil content andfatty acids composition, in response to irrigation at different stages of growing season (at sowing,Dry; from sowing to beginning of flowering, S-BF; from visible bud to 75% flowering, VB-FF;from beginning of flowering to seed ripening, BF-M; from sowing to seed ripening, Full), in astandard sunflower ...

The shortage of water resources makes it urgent to increase agricultural irrigation efficiency. In response this need, study develops a real-time adaptive control (RACI) system for border irrigation. Avoiding the need traditional systems calculate soil infiltration properties in real-time, RACI adjusts inflow rate based on difference between actual and expected advance time. Simulations collect...

If your irrigation system is not performing as efficiently as you would like then it may be time to consider updating. This can be done by renewing sprinklers, installing a more advanced control panel, renewing that worn out pump — or a complete redesign of the whole system using modern technology. If you already have Weather-matic equipment installed, Prime offers a full repair and maintenance...

planting at the right time and supplemental irrigation are considered as the effective management practices in increasing rain productivity and rainfed lentil yield and have been discussed in several studies. in this study, the suitable planting date and supplemental irrigation time for lentil in qazvin weather conditions were examined in a computerized model. in this model, soil water content ...

A simulation model was developed to estimate the effect of deficit irrigation upon crop yield. The model was designed to provide relative yield estimates for numerous combinations of irrigation system, crop growth and irrigation management parameters. A daily soil moisture balance was used to predict evaporation and transpiration from which crop yields were estimated. Gross irrigation water req...

Irrigation application in cotton crops is traditionally discharged at a constant rate for an entire field. However, not all plants in a crop may require the same amount of water due to the stochastic nature of the crop response and the spatial variability of environmental factors within the field. Control strategies are required to effectively manage spatially and temporally varied irrigation a...

* Corresponding author. [email protected] Abstract – Previous studies have shown that irrigation can impact the near-surface climate, but none refer to the differences in the impacts of irrigation types such as flooding and spraying. In this study, we add a novel irrigation module to the recently released community land model 4.0 and simulate irrigation in two ways: first, by spraying water...
