Pattern of Fertiliser Uses Under Micro-irrigation System in Poor Quality Water Areas

摘要

Micro-irrigation technologies are more suited to undulating areas where water quality is poor and its availability is extremely scarce.Non-adoption of such technologies also led to problem related to environment,salinity and water-logging etc.and long-term sustainability of agricultural production is also affected badly.The micro-irrigation technologies help save large amount of water and enhance water use efficiency,increase the crop yields,reduce environmental hazard and salinity problems,also help in maintaining ecological balance.By adopting micro-irrigation technologies under such adverse conditions,it is possible to harvest 4-5 tonnes/ha/year wheat with recommended doses of fertilisers.Hence,the study was carried out in selected districts of Haryana where water quality is poor.The water,which cannot be used for irrigation purposes directly,can be used safely as damage losses to crops are reduced.The quantity of different type of fertilisers kg/ha used by the farmers was recorded and it was observed that majority of them were using less or higher doses of fertilisers for different crops without consulting any agricultural specialists/experts.Comparative advantages of sprinkler vs.traditional irrigation on farmers' fields were also recorded and it was observed that there was an increase in yield of different crops,namely,wheat,bajra,barley,mustard,cotton and gram,respectively,after adoption of sprinkler irrigation.The data also clearly indicated that in sprinkler irrigation there was time,water and monetary saving in addition to income generation.
