Abstract:
A two-year field experiment was conducted during boro seasons of 2015 and 2016 at
Research Farm of Institute of Agriculture, Visva-Bharati University, Sriniketan, West
Bengal, India. The experiment was laid out in a Randomized Block Design with three
replications and fifteen treatments in a typical Lateritic soil of West Bengal. The soil
properties of the experimental site ware sandy loam with acidic in reaction; low in organic
carbon, low in available nitrogen, phosphorus, potassium, sulphur and boron; medium in
available zinc. After harvesting of boro rice, soil samples were analyzed for soil reaction,
electrical conductivity, organic carbon, available N, P, K, S, B and Zn. Application of 2.2
kg B ha-1
, 4.2 kg Zn ha-1
, 0.26 kg Mo ha-1
, 20 kg S ha-1
, RDF along with 2.5 t
Vermicompost ha-1
and 6 kg Azospirillum ha-1 were showed significantly highest grain
yield of boro rice. i.e. 6.66 t ha-1 (T13) followed by T12, T11, T8, T5, T9, T6, T4, T14, T7, T10,
T15, T3, T2 and T1. Integrated nutrient management increased the availability of N, P, K, S,
B and Zn in soil and also increased the yield of boro rice.
