Experiments were conducted to assess the effects of different dripper discharges, dripper spacings and lateral spacings on yield and physical quality attributes of drip-irrigated green beans. Three different drip irrigation systems were arranged as: DS1, in which dripper discharge is 2 L h‒1 , dripper spacings is 33 cm and lateral spacings is 50 cm (a lateral line for each plant row); DS2, in which dripper discharge is 2 L h ‒1 , dripper spacings is 33 cm and lateral spacings is 100 cm (a lateral line for two plant rows); DS3, in which dripper discharge is 4 L h‒1 , dripper spacings is 50 cm and lateral spacings is 100 cm (a lateral line for two plant rows). In irrigations, wetted area percentage was taken as 75%. Present findings revealed that different drip irrigation treatments did not have significant effects on yield and physical quality attributes of green beans. Therefore, it was concluded that lateral spacing in drip irrigation of greenbeans could be selected as 100 cm (a lateral line for two plant rows). This will bring at least 50% saving in lateral pipe costs of drip irrigation systems.

Experiments were conducted to assess the effects of different dripper discharges, dripper spacings and lateral spacings on yield and physical quality attributes of drip-irrigated green beans. For this purpose, three different drip irrigation system were arranged as: DS1, in which dripper discharge is 2 L h‒1, dripper spacing is 33 cm and lateral spacing is 50 cm (one lateral line for each plant row); DS2, in which dripper discharge is 2 L h‒1, dripper spacing is 33 cm and lateral spacing is 100 cm (one lateral line for two plant rows); DS3, in which dripper discharge is 4 L h‒1, dripper spacing is 50 cm and lateral spacing is 100 cm (one lateral line for two plant rows). In irrigations, wetted area percentage was taken as 75%. Present findings revealed that different drip irrigation treatments did not have significant effects on yield and physical quality attributes of green beans. Therefore, it was concluded that lateral spacing in drip irrigation of green beans could be selected as 100 cm (one lateral line for two plant rows).

Volume 20182126

In this paper, drip irrigation green bean farming is evaluated in terms of energy use and economy. The study used data from a research conducted in field conditions on green beans under three drip irrigation systems with different dripper flow and interval and lateral interval. The amounts of inputs used in production, their economic values ​​and product yield values ​​were obtained from the literature within the scope of the study, and the energy equivalents of the inputs and product output were obtained. According to the results obtained, the total energy input in drip irrigation green bean production was determined as 47782 to 53353 MJ/ha according to the drip system design, and the energy produced-energy consumed ratio was determined as between 0.60-0.86. According to the results of the economic analysis, the net income of the subjects was determined as 22195-25014 TL/ha and the gross income-expense ratio was determined as between 1.76 and 1.86, and green bean production was evaluated as economically efficient and sustainable.

IRAQ'S WATER RESOURCES AVAILABILITY AND WATER MANAGEMENT PROBLEMS

Oct 27, 2022

Journal INTERNATIONAL CONGRESS of EDUCATION and SCIENCE

In this paper, Iraq's water resources and water management problems were evaluated. Water is a natural resource that is of great importance in terms of the existence of countries, security interests and economic development beyond its vital importance for human beings. Water resources are the main factor for achieving agricultural production and food security goals. Especially in arid and semi-arid regions such as the Middle East, water problems are increasing even more day by day. The Republic of Iraq is located in the southwest of the Asian continent and creates the northeastern part of the Arab world. It is one of the most important countries of the Gulf with its strategic location and oil reserves. It shares borders with Turkey in the north, Iran in the east, Syria, Jordan and Saudi Arabia in the west, and Kuwait and the Persian Gulf in the south. The total area of Iraq is 438,317 km². The total population for 2022 is 42,104,000 person. Water resources in Iraq consist of rain, snow, surface waters (rivers, streams, lakes) and groundwater. The most important surface water resources of the country are the Tigris and Euphrates rivers. These rivers is fed from the basins of six countries, including Turkey, Iraq, Syria, Iran, Saudi Arabia and Jordan. The largest area (46.4%) of the Tigris and Euphrates basins is in Iraq. These are the soruce of life of Iraq. Groundwater is Iraq's third most basic water resources and its annual potential is estimated to be 6 billion m3. The most important and most common groundwater source of the country is wells. The average share of drinking water per capita in Iraq is 397 liters per day. Since the water reserves of water resources are gradually decreasing, the per capita water is also decreasing, and there is even a decrease in the amount of water used for agriculture and other sectors. As a result of the survey studies, there is a serious problem in water management in Iraq. The most important of the problems can be summarized as follows; The Iraqi economy's dependence on oil as the only source of wealth, neglect of other sectors, including the agriculture sector, the scarcity of water produced in large terrain and the desertification situation as a result of global warming which leads to a decrease in climate, weather conditions and precipitation, lack of modern agricultural mechanization to support the farmer in reclaiming farmland, the prevalence of administrative problems in government institutions and most of the agricultural facilities hinders the progress of the agricultural sector. Therefore, the Iraqi government should take serious measures to have a strategic view of water management.
