Problem solved through this practice |
Uneven distribution of irrigation water, lack of water accounting means to ensure observance of recommended irrigation norms for cotton |
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). |
Tools used in the practice |
Tubular water outlet flowmeter |
Drip irrigation in combination with soil mulching with polyethylene film |
Description of the practice and its results |
Actions:
- Construction of tubular water outlet flowmeter with removable nozzles (procurement of polyethylene piping to make tubular water outlets and matching nozzles); - Installation of tubular water outlet flowmeter along temporary sprinklers.
Results:
Financial and economic:
saving of irrigation water; low cost of irrigation system automation (total kit cost: $500/ha) with the service life of 5 years.
Technical:
simple design allowing a more even distribution of irrigation water stream among furrows, thus, ensuring the prescribed water supply mode.
Social:
improved working conditions of irrigators; lower labor needs/costs; enhanced mutual trust among farmers and water users. |
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. |
Lessons learnt and recommendations made |
Lessons learnt:
Installation and deployment of tubular water outlet flowmeter allows to improve the uniformity of irrigation stream’s distribution among furrows and conduct irrigation water accounting.
Recommendations:
It is necessary to widely use the small-scale irrigation automation means like the tubular water outlet flowmeters which have simple design, are convenient to operate, are low-cost and mobile and ensure supply of the prescribed amount of irrigation water. |
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.
