Fifty eight (58) irrigation water samples were collected from 58 villages of Chirawa Block, Jhunjhunu district. The cations and anions in irrigation waters were found in the order of Na+ > Cl- > CO3(2+) + HCO3 > Ca2+ (+) Mg2+ > SO4(2)- > K+. SAR and RSC of the waters ranged between 2.54 to 17.21 and 0.10 to 6.0 meq/l, respectively. pHc and adj. SAR of the waters ranged between 7.1 to 8.2 and 4.0 to 36.0 respectively. EC of irrigation water has significant positive non-significant correlation with EC of soil and weak positive correlation with pH of soil. Significant positive correlation was found in SAR (0.53) and RSC (0.47) of irrigation water with pH of soil.
从朱尼胡努区奇拉瓦街区的58个村庄采集了58份灌溉水样。灌溉水中阳离子和阴离子的顺序为：Na+ > Cl- > CO3(2+) + HCO3 > Ca2+ (+) Mg2+ > SO4(2)- > K+。水的钠吸附比（SAR）和残留碳酸钠（RSC）分别在2.54至17.21和0.10至6.0 meq/l之间。水的pHc和调整后的SAR分别在7.1至8.2和4.0至36.0之间。灌溉水的电导率（EC）与土壤电导率呈显著正相关但不显著，与土壤pH呈弱正相关。灌溉水的钠吸附比（0.53）和残留碳酸钠（0.47）与土壤pH呈显著正相关。
