摘要

灌溉水的质量是植物生长的重要方面之一,它一直是发展中国家和发达国家关注的一个主要问题。在过去的十年里,该国的灌溉面积经常增加,这导致了更高的产量潜力。如果使用质量差的灌溉水,就会导致产量下降。因此,在灌溉用水用于农作物之前,有必要对其质量进行评估。试图使用各种水质参数评估卡纳塔克邦Chikkamagalur区Chikkamagarur区块不同村庄的地下水质量。pH值范围为6.3至8.0,电导率范围为0.10至1.10dSm-1。灌溉水中的钠和钾含量分别为0.13至3.83和0.10至5.12meq L-1。钙和镁的含量表示水的硬度,是重要的阳离子,记录在0.60和5.85meq L-1之间。氯化物浓度为4.40至11.2meqL-1,碳酸氢盐浓度为0.4至8.8meqL-1。根据灌溉水质指数(IWQI),研究区87.5%的水样水质较差,略不可持续灌溉,8.3%的水样非常差,只有~4.2%的水样质量良好。

Ground water quality assessment of different villages of chikkamagalur block in Chikkamagalur district of Karnataka
Quality of the irrigation water is one of the important aspects for plant growth and it has been a major global concern in developing and developed countries. There has been a regular increase in the irrigated area in the country in the last decade that led to a higher yield potential. If poor quality of irrigation water is used it results in decreased yield. So there is a need to assess quality of the irrigation water before its use on the crops. An attempt was made to assess the ground water quality of different villages in Chikkamagalur block of Chikkamagalur district in Karnataka using various water quality parameters. The values of pH ranged from 6.3 to 8.0, while electrical conductivity ranged from 0.10 to 1.10 dS m-1. Sodium and potassium content in the irrigation water ranged from 0.13 to 3.83 and 0.10 to 5.12 meq L-1, respectively. Calcium and magnesium contents which indicate the hardness of the water and are the important cations was recorded between 0.60 and 5.85 meq L-1. Chloride concentration varied from 4.40 to 11.2 meq L-1, while bicarbonate ranged from 0.4 to 8.8 meq L-1. Based on irrigation water quality index (IWQI), it was found that 87.5% of the water samples of the study area was poor in quality and slightly unsustainable for irrigation, while 8.3% was very poor and only ~4.2% was good in quality for irrigation.
