20.500.12556/RUL-170766 Effect of high residual sodium carbonat (RSC) water and amendments on soil properties under rice-mustard (Brassica juncea ‘Khanpur Raya’) rotation Učinek velikih vsebnosti rezidualnega natrijevega karbonata (RSC) v vodi in dodatkov na lastnosti tal v kolobarju riža in gorjušice A trial was designed to study the deleterious ef-fect of high RSC water on soil properties under rice-mustard crop rotation. Treatments included were; T1: high RSC water, T2: gypsum on the basis of RSC of water, T3: H2SO4 on the basis of RSC of water, T4: green manuring with guar, T5: farm yard manure (FYM) at the rate of 10 t. ha-1. For irrigation tube well water having (electrical conductivity (EC) 1.37 dS m-1, sodium adsorption ratio (SAR) 8.40 (mmol l-1)1/2 and RSC 7.85 me l-1) was used. The results revealed that lowest paddy (2.22 t ha−1) and grain yield (1.00 t ha−1) of rice and mustard were recorded when irrigated with high RSC water. In case of soil analysis, long-term use of high RSC water induces secondary salinity by increasing pH (1.92 %), EC (5.73 %) and SAR (35.71 %) over their initial values. Harmful effects of high RSC water were thwarted by all the treatments; however, positive effects of gyp-sum were more visible that increased crop growth and grain yield of rice-mustard crops by promoting soil properties. Gyp-sum recorded the highest paddy and grain yield (3.66 t ha−1, 1.70 t ha−1) of rice and mustard crop and decreased soil pHs(4.98 %), ECe (29.93 %) and SAR (54.54 %) over their initial values. Poskus je bil izveden z namenom preučiti škodljive učinke velikih vsebnosti natrijeva karbonata na last-nosti tal v kolobarju riža in gorjušice. Obravnavanja so bila; T1: velika vsebnost RSC v vodi, T2: dodatek sadre vodi z veliko vsebnostjo RSC, T3: dodatek H2SO4 vodi z veliko vsebnostjo RSC , T4: zeleno gnojenje z guarom, T5: dodatek hlevskega gnoja (FYM) v odmerku 10 t ha-1. Za namakanje je bila up-orabljena voda iz vodnjakov naslednjih lastnosti: električna prevodnost (EC 1.37 dS m-1), razmerje adsorbiranega natrija (SAR; 8.40 mmol l-1)1/2 in RSC 7.85 me l-1). Rezultati so poka-zali, da je bil najmanjši pridelek biomase (2,22 t ha−1) in zrnja (1,00 t ha−1) v kolobarju riža in gorjušice pri zalivanju z RSC vodo. Analize tal so pokazale, da je dolgotrajno namakanje z RSC vodo povzročilo sekundarno salinizacijo s povečanjem pH (1,92 %), EC (5,73 %) in SAR (35,71 %) glede na začetne vred-nosti. Škodljivi učinki namakanja z vodo z veliko vsebnostjo rezidualnega natrijeva karbonata so bili oblaženi z vsemi ob-ravnavanji vendar je bil največji pozitivni učinek opažen pri do-datku sadre zaradi izboljšanja lastnosti tal, kar je povečalo rast poljščin in pridelek zrnja riža v kolobarju riža z gorjušico. Do-datek sadre je dal največji pridelek biomase in zrnja riža (3,66 t ha−1, 1,70 t ha−1), zmanjšal pH (4,98 %), električno prevodnost (ECe ; 29,93 %) in SAR (54,54 %) glede na njihove izhodiščne vrednosti. residual sodium carbonate rice mustard salinity sodic water gypsum sulfuric acid guar rezidualni natrijev karbonat riž gorjušica slanost slana voda sadra žveplena voda guar true false true Angleški jezik Slovenski jezik Članek v reviji 2025-07-15 15:23:51 2025-07-15 15:23:58 2025-07-18 03:48:32 0000-00-00 00:00:00 2025 0 0 12 str. no. 2 Vol. 121 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 633 1854-1941 10.14720/aas.2025.121.2.18513 242637059 Ahmed+et+al.+(D).pdf Ahmed+et+al.+(D).pdf 1 24D12672028B8A33045D6BE7591A8236 984bd03dd310edf80c486493fec1f6986bb3540349af079bc13a7782c1d5f80d 2a5d8d34-617d-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=212954 https://journals.uni-lj.si/aas/article/view/18513/18439 1 06e6db5b-617d-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=212953 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
