Abstract:

In Pakistan many soils out of total lands are occupied by sodic soils which in turn is upsetting farmer's income and cause soil quality decline. This trial was led to appraise the toxic consequences of NaHCO3 on growth as well as rice yield parameters. Various levels of NaHCO3 or Sodium Adsorption Ratio (SAR) were developed in the normal soil. This experiment comprised of 7 treatments that were repeated three times according to Completely Randomized Design (CRD). These treatments included; T 1= Control, T2= 15 SAR, T3= 20 SAR, T4= 25 SAR, T5= 30 SAR, T6= 35 SAR and T7= 40 SAR. Subsequently NaHCO3 was added to the soil as per treatment plan and adequate time was allowed to accomplish chosen sodicity levels. Later on, rice nursery was transplanted in all the pots. Various agronomical operations were carried out as per crop requirement. At maturity, rice was harvested from all pots. Various yield contributing components like plant height, fertile tillers, total biomass, straw and paddy yield were noted for all pots of the experiment. Statistical analysis of all collected data was accomplished. It was noted from the results that control (T1) proved superior with regard to plant height, fertile tillers/pot, total biomass, straw and paddy yield. All these yield contributing components indicated a declining trend in all subsequent treatment. Treatment T7 (40 SAR) proved inferior to all others in these regards.
