Micro Irrigation

Eight hundred million of the current 1.1 billion people who earn less than a dollar-a-day live in rural areas in developing countries. Since more than 550 million of them earn their living from agriculture, poverty eradication depends on increasing their income from farming. The millennium goals for hunger and poverty in the semi-arid tropics will not be met without four simultaneous revolutions. A revolution in water is needed to develop and mass disseminate a whole range of new affordable small plot irrigation technology. A revolution in agriculture is required to enable smallholders to produce a variety of high value marketable labor intensive cash crops. A revolution in markets is needed to open access to inputs and to profitable markets for their high value crops, incorporating effective strategies for aggregation, quality control, and decentralized added value processing. Finally, a revolution in design based on the ruthless pursuit of affordability is needed to support the other three revolutions. This paper describes the rapidly growing micro-irrigation revolution exemplified by the $250 million in new net annual income now being earned by Treadle Pump farmers, and outlines the key features of the other three revolutions required to meet millennium poverty goals.

Efficient Water Use

The deficit of the irrigation water requires irrigation technologies with more efficient water use. For cucumbers, the most suitable is the drip irrigation technology. For establishing of the appropriate irrigation schedule of cucumbers under the soil and climate conditions in the village of Chelopechene, near Sofia city, the researchеs was conducted with drip irrigation technology, adopting varying irrigation schedules and hydraulic regimes - from fully meeting the daily crops water requirements cucumbers to reduced depths with 20% and 40%. It have been established irrigation schedule with adequate pressure flows in the water source, irrigation water productivity and yields of in plastic unheated greenhouses of the Sofia plant.

Operation Characteristics

If the center pivot or linear moving irrigation machines are operated with their own individual irrigation technologies, but the irrigation machines with combined center-pivot and linear moving mode are operated on one field in turn as a center pivot and as a linear. The goal of this work is creation of theoretical base for calculation of improved irrigation machines parameters and existing irrigation equipment modernizing, according to the different natural conditions. The research object is investigation of characteristics of rain delivered from irrigation machines with combined center-pivot and linear moving mode, assuring uniform irrigation distribution according to the irrigation technology and operation parameters, size and configuration of seasonal norm as well as to the irrigation scheduling. The pointed goal is achieved by the given problem solving, when having basic data on the irrigation norm and time, as well as operation characteristics and the irrigation area configuration, the predicted hydro modulus are calculated for the irrigation machine working in a center pivot and in a linear mode. The simulation of sprinkling devices operation on the machine is made by one universal formula, when on the plots irrigated in center pivot and linear mode is achieved equality of arranged hydro modulus to the corresponding calculated data. At that, are considered all the possible combinations of the total irrigated area parts, irrigated with different technologies.

Main Factors

Quinoa is considered a strategic crop because it is well adapted to the adverse abiotic conditions of the Bolivian Altiplano; however, the average yield is low. Previous studies have demonstrated that quinoa yield would increase with deficit irrigation technology. Nevertheless, to irrigate quinoa is not a normal practice in the farming systems of the Altiplano. This paper examines the main factors that determine the attitude of farmers towards adopting deficit irrigation using a sample of 137 surveys in seven communities of the Central Altiplano. Statistic analysis demonstrates that the most important factors influencing farmers' willingness for irrigation adoption are the acreage planted with quinoa, quantity of surplus production for trading, and having irrigation experience. Also, the age and education level were important to know willingness to adopt a new technology. Therefore, deficit irrigation is more likely to be performed in area where farmers own larger fields and where there is already certain type of irrigation.
