This topic provides select best practices related to Irrigation Water Management.

Mission Kakatiya, Telangana

Place of implementation : Telangana
Implementing agency : Telangana State Government

Intervention

Mission Kakatiya is a flagship program under Telangana government aimed at restoring minor irrigation sources of water like ponds and tanks. The objective is to enhance the development of Minor Irrigation infrastructure, strengthening community based irrigation management in a decentralized manner and to adopt a comprehensive programme for restoration of tanks and sources of water to effectively utilize 265 TM of water allocated for minor irrigation sector under Godavari and Krishna river Basins. Gram Sabha were conducted and the proposed plans were discussed with the villagers. Farmers were motivated to co-operate and were suggested to deposit the silt for field preparation. Several district level coordination committees were formed. Emphasis was given for improvement in delivery time of services. Steps like tank de-siltation, restoration of the feeder channels, re-sectioning of irrigation channels, repair of bund, weir and sluice, raising of FTL (Full Tank Level) wherever required were carried out.

Achievements

The intervention helped in increasing the storage capacity of tanks and other water bodies. It helped in making water available and accessible to small and medium farmers in particular and benefitted other farmers as well. The intervention helped in increasing the water retention capacity of the sources and also helped in improving the on-farm moisture retention capacity. The intervention bridged the 63% ayacut gap and also helped in stabilization of ayacut under minor irrigation. Measures like mixing of the slit on farm land preparation reduced the use of chemical fertilizers and also improved the land water retention capacity. An appreciable change was observed in the nutritive values of the soil. It resulted in diversification of high value crop and crop intensification and also gave rise to loop irrigation. Other achievements that accompanied the project are development of fisheries and livestock and rise in the ground water levels in that area. The increase in plantati on of palm trees on the slopes also added to the income generation for the rural people.

Takeaways

  • Public participation will lead to ownership and help in long-term sustainability of the interventions.
  • Restoration and maintenance of water resources should be a continual process and local people should be trained to manage their resources.

Mulching: Harvesting Many Benefits in Cardamom, Kerala

Place of implementation : Western Ghats
Implementing agency : The Indian Cardamom Research Institute (ICRI)

Intervention

Any material, usually organic, that is spread on the ground to protect the soil and the roots of plants from the effects of soil crusting, erosion, or freezing is known as a Mulch. A mulch may be made of materials such as straw, sawdust, grass clippings, peat moss, leaves, or paper etc. For large areas under cultivation a tilled layer of soil serves the purpose of a mulch but intensive cultivation of cardamom, ignoring the traditional cultural practices, has resulted in repeated losses. The Indian Cardamom Research Institute (ICRI) studied the soil fertility on a farm and found that the organic carbon/humus content is higher in the farms where this technique is practiced compared to neighbouring plantation. The soil bulk density is also very low. Mulching reduced the acidity of the soil and increased the soil moisture.

Achievements

The studied showed significant achievements like high humus content on farm. It was observed that mulching resulted in several advantages - the plant growth is healthy and the damage due to thrips on capsules and stem borer is negligible; the height of the 17 year old plant is 15 – 20 feet tall and there are about 100 tillers in each clump. Usually cardamom fields are replanted with new suckers in 8 - 10 years of cultivation. But mulching helped in retaining the plantation successfully for 17 years with compact clumps. There is no need for weeding as the soil is not exposed and self-shade of cardamom clumps discourages weed growth.

Takeaways

  • Mulching helps in conserving soil moisture
  • It also acts as temperature regulator in hot summers and cold winters.
  • Live mulching technique is very good for nitrogen fixation.
  • Organic waste generated from field can fruitfully be utilised to reap significant benefits.
  • Growth of unwanted weeds can be cont rolled in farm using this technique.
