Abstract


A field experiment was carried out on TwinN in Rabi sorghum at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad Karnataka during Rabi seasons (2009 and 2010) to evaluate the sorghum growth and growth parameters. The experiment was laid out in Randomized Block Design with eight treatments and three replications. The pooled results for two seasons showed significantly higher plant height (230.33 cm), number of leaves per plant (9.23), root length (19.20 cm), dry root mass (84.33 g) and ear head girth (19.07 cm) were recorded in 40:40:40 N:P2O5:K2O kg/ha with two TwinN sprays at 5th leaf and flower primordial stage(T5) which was at par with 80:40:40 N:P2O5:K2O kg/ha. Further dry matter production and accumulation in stem, leaves, ear heads and TDMP (42.44,4.88,22.92 and 68.19 g /plant, respectively) also showed similar trend in T5
