Effect of drip irrigation on the production and economic returns of sorghum (sorghum bicolor) in semi arid areas of Tanzania

Field trials were conducted in semi arid area of Dodoma, central Tanzania with the aim of assessing the effect of three drip irrigation watering regimes on the production and economic returns of sorghum (Sorghum bicolor). The irrigation treatments were: EM (early in the morning), EL (late in the evening) and ELE (both early in the morning and late in the evening). Each treatment was replicated three times in a RCBD for two seasons (dry and wet season).

Impacts of land-use changes on the soils of the Nguruman area, Kajiado district.

This paper considers the impact on soils physical (texture and structure) and chemical (pH, electrical conductivity and exchangeable sodium percentage) characteristics of changes in land use following clearing of vegetation for cultivation under both rain fed and irrigated conditions in the Nguruman area of Kajiado District, Rift Valley Province, Kenya. The results show that the accumulation of salts was directly related to the physiographic position of the soils and their texture.

Farmers’ perspectives on factors limiting tomato production and yields in Kabete, Kiambu county, Kenya.

A survey was carried out at Kabete, Central Kenya to establish the limitations and constraints experienced by farmers’ growing tomatoes. A structured questionnaire was prepared and tested in the field before actual survey was carried out. Fifty farmers were interviewed and with the data analyzed it was established that most farmers lacked enough land; irrigation water; cash and technological know-how to enable them optimize tomato production especially during dry spells when they could fetch premium prices.

GIS based Multi Criteria Analysis in Mapping Potential for Irrigated Agriculture. Case study: Machakos County

Agriculture in Kenya is fundamental in economic development, it contributes 35% of the gross domestic product and such remains the backbone of the economy, it’s growth is important for alleviation of poverty and stimulation of economic growth and development. Economic growth and development envisioned in the Kenya Vision 2030 can only be achieved by investing and transforming this sector of the economy which ensures constant food supply and food security for the population. Through all this multiplier effects agriculture is perceived to be an engine of economic growth and development.

Characterization of irrigation farm households and economic valuation of irrigation water: the case of Ahero Rice Irrigation Scheme in Nyando district of Kenya

Irrigated farming can play a great role to enhance agricultural development in Kenya, given that Kenya's economy is predominantly agricultural based and that about 80% of Kenya's land area is arid and semi-arid land (ASAL) where annual rainfall rarely exceeds 400 millimetres. However, irrigation tends to be carried out under intensive water use and low water use efficiency in many parts of the world, Kenya included. Household characteristics and subsidized or low water charges have been identified as a major contributor to intensive water use and low water use efficiency in irrigation.

Modern technology and sustainable irrigation of small scale dry-land farming in Kitui county, Kenya

The Purpose of this study was to investigate the influence of technology on sustainable irrigation of small scale dry land farming in Kitui Central District, Kitui County, Kenya. The study sought to establish the extent to which adoption of new irrigation technology, gravity free flow irrigation and access to access to credit has influenced sustainable irrigation of small scale dry land farming. Descriptive survey research design was adopted. A sample of 150 participants was randomly selected from 1540 small-scale dry land irrigation farmers in the district.

The role of resource use optimization in improving farm incomes in small-scale irrigation schemes: a case study of Mitunguu irrigation project in Meru district, Kenya.

This research was carried out in Mitunguu Irrigation Project which is an organised Smallscale Public Irrigation Scheme.Mitunguu Irrigation Project covers 400 Ha of gravity fed sprinkler irrigation. The project has a potential of upto 1500 Ha of irrigable land. Each farm within the project is provided with a hydrant box so that the irrigation water in each farm is opened only when irrigation needs arise. Fanners with land holdings larger than 2 Ha are supplied with irrigation water sufficient to irrigate 2 Ha only. Those with land holdings of less than 2 Ha.

Factors Influencing Shift from Pastoralism to Irrigated Agriculture and its Impact on Soil Quality in Kajiado

Crop cultivation in the arid and semiarid ecosystems is mainly constrained by inadequate and unreliable rainfall. Smallholder irrigation in such areas is therefore necessary to supplement l rainfall to meet crop water requirements. As cultivated agriculture encroaches into marginal ecosystems that are fragile and delicate, there is need to understand the drivers of the transition from pastoral to irrigated agriculture and the effects of irrigation on soil quality for better management of the smallholder irrigation systems towards increased and sustainable crop production.

Factors Influencing the Performance Of Smallholder Irrigation Schemes in Nyanza Province: A Case of South West Kano Nyando, Kenya

Irrigation is the controlled application of water for agricultural purposes. It is necessary when rainfall is insufficient to meet the water requirements for crops throughout their growing period. There are over 250million ha globally under irrigation with Nyanza province only having 7264 ha despite the fact that agriculture is the backbone of the economy. Irrigation practice uses different technologies and management approaches.

Factors Influencing Conflict Within Management During Implementation Of Irrigation Projects In Mukurweini Constituency, Nyeri County- Kenya

All over the world implementation of the community based irrigation projects involve execution of activities by team leaders elected from the self-help group whose composition is not based on professionalism but by membership and therefore faced with conflict challenges. Effectively managed conflicts can have positive outcomes while unresolved conflict undermines projects and relationships, as well as the morale and reputations of stakeholders.
