Abstract
Field experiments were conducted in red lateritic soils of National Pulses Research Centre, Vamban, for investigating the influence of organic and inorganic amendments for overcoming soil crusting and hardening conditions using black gram (KB 51) as test crop. Results showed that bulk density and soil hardness were favourably influenced by application of pressmud (5 tha). Grain yield of black gram increased due to application of amendments from 31.8 to 74.5% per cent. Experiment on the residual effect of amendments indicated positive influence on the yield of the succeeding crop.
