The present study was undertaken to study the influence of sowing methods and mulching on soil salt dynamics and performance of fodder sorghum. Results showed that the application of saline water (4 irrigations with 6.0 dS/m EC), gradually increased the soil salinity in soil profile depth of 0-60 cm. The mean soil salinity in 0-60 cm soil increased by 127.2 per cent over normal irrigation water. Among the sowing methods, ridge and furrow sowing with alternate furrow irrigation recorded lowest salinity development in upper soil layers. The salinity was 36.4 and 49.1 per cent higher under two row raise beds as compared to ridge and furrow in upper 0-15 and 15-30 cm soil layers, respectively. Mulching with crop residue maintained lower levels of salinity over bare soil. Mulched soil had 24.8 per cent higher moisture content in 0-60 cm soil profile then un-mulched treatment. Irrigation with saline water significantly reduced the fodder yield of sorghum by 10.6 per cent as compared to irrigation with normal water. Sowing of fodder sorghum on two row raised beds recorded significantly highest fodder yield over flat bed and ridge and furrow sowing which was 8.2 per cent higher over flat bed sowing.
