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.

• Title: Učinek velikih vsebnosti rezidualnega natrijevega karbonata (RSC) v vodi in dodatkov na lastnosti tal v kolobarju riža in gorjušice

Abstract

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.
