A field experiment was conducted at Instructional-cum-Research (ICR) farm, Assam Agricultural University, Jorhat during 2016. The experiment was laid out in split-plot design with three replications. The treatments consisted of three different tillage practices in main plots viz., minimum tillage (T1), zero tillage with non-selective herbicide (Glyphosate) (T2) and conventional tillage (T3) along with sources of nutrient - recommended doses of fertilizer (F1) 60:20:40 N:P2O5:K2O kg/ha, 50% N replacement through Vermicompost + 50% RDF of N and full RDF of P2O5 and K2O (F2) and 50% N replacement through Enriched compost + 50% RDF of N and full RDF of P2O5 and K2O (F3) in sub plots. The results of the experiment revealed that growth characters of rice were significantly influenced by different tillage treatments. Conventional tillage recorded significantly higher growth and yield attributing characters. Conventional tillage also recorded significantly higher grain yield (42.81q/ha) and straw yield (71.83q/ha) over other tillage practices. The INM treatment receiving 50% N replacement through Enriched compost +50% RDF of N and full RDF of P2O5 and K2O shown its superiority in regards to growth and yield attributing characters of rice. The grain yield (38.26q/ha) as well as straw yield (66.66q/ha) obtained in this treatment were significantly higher than other treatments.
