After disintegration of large agricultural enterprises (state farms), the maintenance of inter- and intra-farm irrigation systems – that were earlier on the balance of state farms – appeared to exceed the technical capacity of small-scale private and owner-operated farms.  Due to this reason, in the majority of agricultural districts the tray irrigation networks got out of order.  The wear of the lion’s share of hydraulic engineering facilities in Alakol District reached nearly 70% leading to water losses associated with crops watering – the analysis showed that 40% of water was lost to filtration and evaporation.  In its turn, that resulted in ineffective and irrational use of water resources and contraction of irrigated land area.  For example, whereas in 2003 water intake for irrigation amounted to 195 mln m³, in 2009 it decreased to 114.8 mln m³ (41.1% drop).

Issue: Low efficiency of irrigation water due to wear of hydraulic engineering facilities/installations (tray irrigation system).

Low efficiency of furrow irrigation; deficit of irrigation water; poor alfaalfa yields; eroded soil; low income of farmers.

Drip irrigation in combination with soil mulching with polyethylene film

Sprinkling irrigation system for alfaalfa

Drip irrigation combined with filming has been widely adopted around the world in vegetable and cucurbits cultivation.  Thanks to long moisture preservation and proper thermal balance achieved under film, deployment of this technology allows reducing the overall need for irrigation water and receiving earlier and higher crop yields.

Actions:

The K-DEN Farm was offered to apply drip irrigation through film cover on the area of 5 hectares in Yntaly Rural District.  The technique was adapted for project site by Doctor of Engineering R.I. Vagapov. The recommended technology is the most available to local farmers and ensures significant saving of irrigation water.

Necessary resources:

1) seeds of vegetable and cucurbit crops;

2) polyethylene film;

3) equipment (DT-75 tractor, seeder, cultivator);

4) labor for preparatory works, sowing and harvest campaigns;

5) expert consultations and training.

Results:

Financial and economic:

The yield of vegetable and cucurbit crops increased twofold compared to two previous years allowing the farm to receive the profit of $12,000/ha in spite of the fact that the whole yield was sold at low price to the local population of Eastern Kazakhstan and Almaty Regions.  In particular, the productivity of vegetable crops amounted to 350-400 dt/ha, and cucurbits – 400 dt/ha.

Technical:

Water saving made 220,040 m³.

Actions:

• Project design and budgeting, procurement of sprinkling nozzles;
• Installation of sprinkling irrigation system, alfaalfa planting and cultivation, crop care.

Results:

Financial and economic:

increased farmer incomes due to better alfaalfa hay yields; enhanced labor productivity; reduced production costs.

Ecological:

improved ecological and reclamation condition of irrigated land; production of ecologically clean goods; significantly reduced unproductive water losses and soil erosion.

Technical:

increased alfaalfa hay yields (29 t/ha) compared to furrow irrigation (on average 18 t/ha); 40% saving of irrigation water.

Social:

increased wellbeing of local residents due to better agricultural yields; reduced hard manual labor.

Lessons learnt:

The practice of drip irrigation in combination with the application of polyethylene film has increased the efficiency of water use and crops productivity as well as reduced labor needs.

Recommendations:

The widespread deployment of water-saving technologies requires the presence of effective financial incentives for at water consumers.

• Domestic tools (outcomes of research by domestic R&D organizations),
• Foreign tools (transfer of foreign experience)

Lessons learnt:

Deployment of sprinkling irrigation systems allows increasing alfaalfa productivity and water saving as well enhancing soil reclamation condition and structure, watering efficiency, etc.

Recommendations:

It is necessary to widely introduce sprinkling irrigation to enhance the efficiency of water and land resources, reduce manual labor costs and save irrigation water.
