The study was conducted at Agricultural Research Centre with the objective of identifying best-performing perennial grass species under supplemental irrigation and advising promising cultivated fodder for smallholder livestock producers. Randomized Complete Block Design six three replications employed. used were T1 (Brachiaria mutica_18659), T2 (Cynodon aethiopicus), T3 (Pennisetum sphacelatum)...

Interpretation of sugarcane field records can bc greatly improved by linking them to a Geographic Information System database, which allows trends to be mapped and queries to be performed. Linking a Geographic Information System to a crop or irrigation model allows simulation of crop yield and irrigation water use efficiency for each field, based on ficld informatton. The Arcview Geographic Inf...

The use of Precision Agriculture systems is in its infancy in Greece, because of the high fragmented land and the adherence of farmers to traditional farming methods. This paper presents the design, implementation and performance evaluation of an integrated agricultural monitoring and irrigation system using energy-autonomous wireless sensors and actuators. Monitoring and irrigation of the fiel...

Drip irrigation is one of the new irrigation methods for optimum use of water resources and increase of irrigation efficiency. The emitters' clogging is the most important problem in these systems. The physical clogging is the most important factor in reducing the discharge and emission uniformity of emitters. The emitter position on the laterals and emitter spacing are the factors that affect ...

The past 50 years of water policy have seen alternating policies emphasize the state, user groups, or markets as essential for solving water-management problems. A closer look reveals that each of these solutions has worked in some places but failed in others, especially when policies attempted to spread them over too many countries and diverse situations. A study of the variable performances o...

In this study, a model was developed to determine the optimal irrigation schedule for the Qazvin Plain in such a way that economic productivity is maximized with the amount of water available and the area under cultivation. The AquaCrop plant growth model was used to determine crop performance in different irrigation programs. The plant growth model was connected to the MATLAB programming envir...
