Irrigated agriculture in Turkey currently consumes 75 percent of the total water consumption, which corresponds to about 30 percent of the renewable water supply. Unfavorable future global climate and economic conditions will increase the stress in the water sector. The operation and maintenance (O&M) of almost all large surface irrigation schemes developed by the state has been transferred to irrigation associations governed by the farmers. The purpose of this paper is to provide an overview of irrigation management practices and an evaluation of irrigation water pricing after the transfer using price data at the association level since 1999. Results indicate that both irrigation water charges and collection rates increased following the transfer. However, the recuperation of investment costs for irrigation development from the users has remained minimal. The price of the irrigation water continued to be on per hectare basis, and farmers using pumping water face 2.5 times higher water charge per hectare then the gravity water users. The uptake of more efficient water application technology accompanied by pricing mechanisms reflecting scarcity value of water will certainly ease the adjustment burden of the irrigation sector in the future.

Land Improvement

Due to greenhouse gas effect temperature around the world will increase (0.06ºC/yr.) resulting in increased evapo-transpiration and increased need of crop irrigation pressurizing ground water resources and its judicious use. An experiment in a deep tubewell area with improved land and irrigation management undertaken in early 1980’s has shown that doubling of agricultural productivity is possible. This system can be taken as mitigative/adaptive measure of climate change.This paper involves experiences of managing tubewell irrigation schemes through improving basically these development parameters in the irrigation command area: Land improvement (land consolidation, rectangular shaping and leveling), Irrigation canal efficiency improvement,Introduction of crop water management, and Evolving Farmers Group into a Co-operative Organization- for managing land collectively. The evaluation has shown that through this intervention approach yields of paddy, wheat, maize and pulse can be doubled in the irrigated areas. This concept might be useful to modify the present policy and program vision of irrigated agriculture development in Nepal through enhancing water productivity a mitigation measure of the effects of climate change. Also, this approach is applicable to surface irrigation schemes of Terai and hills of Nepal.DOI: http://dx.doi.org/10.3126/hn.v10i0.7117 Hydro Nepal Vol.10 January 2012 66-72

Modeling the growth of field-grown tomato (Lycopersicon esculentum Mill.) should assist researchers and commercial growers to outline optimal crop management strategies for specific locations and production systems. A generic crop-growth model (CROPGRO) was previously adapted to simulate the growth of fresh-market tomato under field conditions. Plant growth and development of field-grown tomato, and fruit yields, will be outlined and compared to model predictions for a number of locations in Florida, nitrogen fertilizer rates, and irrigation management practices. Possible application of the model to quantify effects of crop management on crop production will be discussed using simulated yield values for a wide range of environmental conditions.

Salt Affected Soils

Salinity seriously constrains crop yield in irrigated agriculture throughout the world. Also, salinity is a serious threat to agriculture in arid and semi arid regions. Nearly 10 % of the world’s land surface can be classified as endangered by salinity. Salinity in the soil and irrigation water is an environmental problem and a major constraint for crop production. Currently, 20 % of the world’s cultivated land is affected by salinity, which results in the loss of 50 % of agricultural yield. At present, there are nearly 954 million hectares of saline soils on the earth’s surface. All these salt affected soils are distributed throughout the world. The salinity response of legumes in general varies greatly depending on factors like climatic conditions, soil properties, salt tolerance and the stages of crop growth. Successful cultivation of legumes can be achieved by the selection and/or development of a salt-tolerant legume Rhizobium combination although high salinities are known to affect rhizobial activities. The aim of present study is the effect of strains of salt tolerant Rhizobia on IAA, EPS, nodule ARA activity, Nitrogen content, leghemoglobin content, siderophore production, IAR and salt concentration of Groundnut on coastal area of Cuddalore District of Tamil Nadu. The GNR CD-4 is the effect salt tolerance strain compared to other strains.

The earth’s supply of fresh water is fixed. Its distribution is skewed spatially and temporarily. The maximum usage of water withdrawals is by agricultural sector for irrigation. It is socially, economically and culturally entwined with the lives of people. In the course of irrigation development many irrigation projects have been evolved across India. There are various irrigation techniques followed in different parts of India. The continued growth of population, industrialization, urbanization, climate change, emission of greenhouse gases and deforestation build up pressure on available water resources and arable land for food production. It is further worsened with crop production loss, deterioration of water sheds, disappearance of wetlands and reoccurrence of erratic monsoon. The fall of ground water table, deterioration of quality water, salinization, soil degradation, water logging and irrational use of water emphasized the need for conservation of irrigation water sources. While we have adopted many conservation measures like artificial recharge scheme, percolation ponds, check dams, irrigated agriculture modernization and rehabilitation works on the one side, the problem of irrigation water scarcity and shortage in the availability of quality water still persists. Hence, an attempt has been made to study the need s and effective management on conservation of irrigation water resources.

Farming systems play a key role in maintaining the sustainability, productivity as well as provide better income in the farming community. The present study was carried out in Sankarankovil, Vasudevanallur and Kuruvikulam blocks of Tirunelveli district during 2007-08 to 2010-11 under Tamil Nadu – Irrigated Agriculture Modernization and Water Bodies Restoration and Management (TN-IAMWARM). These blocks are come under Nichabanadhi sub basin. The field demonstrations were carried out in 875 ha in these three blocks for various crop components <italic>viz</italic>, paddy, maize, sunflower, cotton, sugarcane and pulses. A total of 569 farmers were selected for field demonstration in improved production technologies (IPT) and conventional method (CM) for various crops viz., paddy, sugarcane, maize, sunflower, cotton and pulses. The results revealed that performance of all crops was better in IPT than CM. The average productivity and income of different crops were significantly higher under IPT as compared to CM. The IPT also gave higher net return and benefit:cost ratio to the farmers as compared to traditional farming. The overall result revealed that the improved production technology with different crops is an adoptable good approach for sustainable production and income generation of the farmers of Tamil Nadu.

A study was undertaken in Bhagwanpur distributary of Vaishali Branch Canal in Gandak Canal Command Area, Bihar to optimally allocate land area under different crops (rice and maize in kharif, wheat, lentil, potato in rabi and green gram in summer) in such a manner that maximizes net return, maximizes crop production and minimizes labour requirement employing simplex linear programming method and Multi-Objective Fuzzy Linear Programming (MOFLP) method. Maximum net return, maximum agricultural production, and minimum labour required under defined constraints (including 10% affinity level of farmers to rice and wheat crops) as obtained employing Simplex method were ` 3.7 × 108, 5.06 × 107 Kg and 66,092 man-days, respectively, whereas Multi-Objective Fuzzy Linear Programming (MOFLP) method yielded compromised solution with net return, crop production and labour required as ` 2.4 × 108, 3.3 × 107Kg and 1,79,313 man-days, respectively. As the affinity level of farmers to rice and wheat crops increased from 10% to 40%, maximum net return and maximum production as obtained from simplex linear programming method and MOFLP followed a decreasing trend and minimum labour required followed an increasing trend. MOFLP may be considered as one of the best capable ways of providing a compromised solution, which can fulfill all the objectives at a time.
