Abstract
Present study investigated the effect of sowing time and organic manure on biochemical attributes of cluster bean (cv. Pusa Navbahar) under the agro-climatic conditions of Sikkim. The experiment was laid outusing eight sowing times [fourth week of April (Sl), second week of May (S2), fourth week of May (S3), second week of June (S4), fourth week of June (S5), second week of July (S6), fourth week of July (S7), and second week of August(S8)] and four organic manure levels [Control (O1), FYM @ 100% of RDF(O2), vermicompost @ 100% of RDF (O3), and FYM @ 50% of RDF + vermicompost @ 50% of RDF (O4)]. Results revealed that both sowing time and organic manure levels shown significant differences in the biochemical traits of cluster bean. The second week of August sowing time + vermicompost @ 100% of RDF (S8O3) recorded the significantly highest level of total sugar (1191.24 mg/100g) and reducing sugar (767.05 mg/100g), while the highest amount of non-reducing sugar (485.33 mg/100g) was recorded in the fourth week of July sowing time + vermicompost @100%of RDF (S7O3). Second week of August sowing time + FYM 50% of RDF +vermicompost @ 50% of RDF (S8O4) resulted in the highest TSS (2.89 oB) and titratable acidity (2.45%) under investigation.
