Comparative impact of organic and inorganic fertilizers on the growth parameters of mustard (Brassica juncea L.) var.M-27

A field experiment was conducted at Borum Village, Itanagar, Arunachal Pradesh to investigate comparative impact of organic and inorganic fertilizer on the growth attributes of Mustard (Brassica juncea L.) during Rabi season 2021-22. The field experiment was laid out under randomized block design (RBD) with 7 treatments in three replications using organic and inorganic fertilizers in combination. The mustard variety M-27 was sown on 9^th January, 2022 and harvested on 15^th April, 2022 since the Mustard variety M-27 used in the experiment is an early maturity variety. Among the treatments, the maximum plant height and number of leaves per plant are 57.84 cm and 11.70 were obtained on 90 DAS with the application of 100% VC + 0% NPK. Meanwhile, the lowest plant height and number of leaves per plant are 38.20 cm and 6.92 on 90 Das were observed under control treatment. From the present investigation it is found that all the growth characters such as plant height (cm) and number of leaves per plant recorded at 30 days interval from sowing upto 90 days significantly influence by the application of 100% vermicompost (T₂). From the present investigation it can be concluded that the higher growth was recorded with the application of 100% vermicompost (T₂).
