abstract
A field experiment was conducted during rabi season of 2021-22 at the Chamelti Agriculture Farm, MS Swaminathan School of Agriculture, Shoolini University of Biotechnology and Management Sciences, Solan to study the effect of waste derived materials (biochar and compost) on yield attributes and yield of rapeseed. The field of the experimental site represented ideal spatial unit in respect of texture, make up and fertility status. The experiment was laid out in randomized block design with three replications comprising of eight treatments of waste derived materials viz. (T₀) Control, (T₁) Biochar @ 2.5 t ha^-1, (T₂) Biochar @ 5.0 t ha^-1, (T₃) Biochar @ 10.0 t ha^-1, (T₄) Compost @ 5.0 t ha^-1, (T₅) Compost @ 8.0 t ha^-1, (T₆) Compost @ 8.0 t ha^-1 and (T₇) 50% biochar + 50% compost. Him Sarson-1 variety of rapeseed was used for sowing. Application of waste derived materials (biochar and compost) were done as per treatment. Other crop management practices were followed as per the recommendation of the area. It is to be concluded that marked improvement in yield attributes and yield of rapeseed were observed with application of Compost @ 10.0 t ha^-1 under Solan conditions.
