Sodic soils have immense productivity potential, if managed throughproper technology interventions. Biocompost is prepared by composting pressmuda sugar industry byproduct received from cane juice filtration and spent washreceived from distilleries through microbial aerobic decomposition and can beused to reclaim sodic soils. Field experiments were conducted during the wetseason of 2011 and 2012 to study the effect of incorporation of biocompost insodic soil with four treatments: T1—Control, T2—Biocompost at 2 t ha-1,T3—Biocompost at 4 t ha-1 and T4—Biocompost at 6 t ha-1.The two promising salt tolerant rice varieties preferred by farmers, Narendrausar 3 and NDR 359 were used as test crops, which can produce yields rangingbetween 2-4 t ha-1 in soil having a pH range of 9.2 to 10.5. Among the different doses ofbiocompost tested, application of biocompost at 6 t ha-1 registeredhighest yields, enabled by a higher biomass, ear bearing tiller EBT, andgrain fertility in both varieties. Narendra usar 3 was more responsive totreatments even at lower doses of biocompost than NDR 359, but NDR 359 yieldedslightly higher than Narendra usar 3 in all treatments. Soil health was alsoimproved evidently on better fertilityand low soil pH and EC at harvest. Thus, biocompost can be considered as a commerciallyviable, environmentally acceptable and practically enforceable option forimproving the crop productivity and soil fertility status.
