- Notes:
- 5 pages, We developed an Excel-based computational template Extension educators can use to assist clientele with scheduling irrigation for efficient use of water. With the template, the user applies the dual crop coefficient method to calculate evaporation and transpiration rates separately, with the result being more accurate soil water tracking as compared to what occurs when a single crop coefficient is used. Crop water needs can be conveniently calculated on the basis of soil characteristics, crop growth stages, and weather information. Application examples demonstrate that the amount and frequency of irrigation should be adjusted according to soil texture. The template and application examples are available to Extension professionals as electronic supplementary material.

- 12 pages, We use the 2013 cotton precision farming survey data to study the adoption of irrigation technologies by cotton farmers in 14 states of the United States. We find that farmers with a higher irrigated yield, and who are from the Southern Plains (Texas and Oklahoma), adopt water-efficient irrigation technologies, such as sub-surface drip and trickle irrigation technologies. There are 10 irrigation technologies that farmers can adopt for cotton production in these 14 cotton-growing states. The intensity of the irrigation technologies, as measured by the number of irrigation technologies adopted in cotton production, is affected by the irrigated cotton yield realized, land holding (total land owned), education, computer use, and the origin of the cotton farmer being from the Southern Plains. We use a multivariate fractional regression model to identify land allocation by the different irrigation technologies used. Our results indicate that significant variables affecting land allocation with different irrigation technologies are the age of the operator, the cover crop, the information sources used, the per acre irrigated yield, the education, and the cotton farmer being from the Southern Plains.

- Notes:
- 16 pages, The study examined the factors that drive decisions to adopt and use irrigation technologies among smallholder farmers in Machakos County, Kenya. Data were collected from a sample of 300 smallholder farmers. Cross-sectional survey design, a multistage sampling procedure and random sampling method were employed. Percentages, means and econometric analysis were used in data analysis. Results showed that, 31.7% of the respondents practiced irrigation. Sex of household head, education, farm size, off-farm income, credit accessed and access to extension services positively influenced adoption of irrigation technologies. Adoption intensity was positively influenced by gender, off-farm income, farming experience, primary occupation and extension services. As a result, it is suggested that while formulating development strategies and programs for smallholder farmers, agricultural extension organizations should give priority to these factors.

- 10 pages., Via online journal., The purpose of this study was to investigate the factors influencing people's participation in the exploitation of water resources for agriculture. The population consists of experts with a B.A. and higher degree employed in various sectors of Agriculture Organization, Water Organization and Research Center of Urmia city. The sample was randomly selected, and the sample size was determined through Kerjice and Morgan table to be 196. This is an applied field study. The survey tool is a structured questionnaire with close-ended question and its validity and reliability is confirmed by experienced professors, and Cronbach's alpha coefficient which indicates the validity of the questionnaire is calculated to be 0.834. The results show that there is a significant relationship among the administrative, social, cultural, educational, economic, ecological, technical, structural and political factors and the importance of people's participation in the exploitation of water resources for agriculture. The results of multiple regression showed that the independent variables explained 66 percent of the dependent variable variance. According to finding in this research these recommendation comments: Improvement and shortening of water transfer networks in order to speed up the transfer of water and reduction of water loss. Government financial support in the agricultural-industrial sector in order to use new technologies. Preventing economic, social, environmental and political losses due to Urmia Lake drying. Maintaining the diversity of plants and crops through water management and environmental management and environmental ethics. The role of mass media such as radio and television, the use of other channels of communication in highlighting the importance of optimal water consumption. Government support for farmers to renew or launch pipeline for farms and gardens to prevent water losses, as well as supporting new irrigation methods and repairing old transmission lines. Increasing cooperation between people and society and even the state regarding participation in the optimal use of water resources.
