Abstract:
The field experiment to study the “Efficacy of different Liquid Biofertilizer under varying Fertility Levels on Growth and Yield of Chickpea (Cicer arietinum L.)” was laid out at research farm, RARI, Durgapura for two conductive years during rabi seasons of 2015-16 and 2016-17 on loamy sand soil. In all twenty eight treatment combinations consisting of four fertility levels i.e. control (F₀), 50%N + 75%P₂O₅ + 75%K₂O + 50%S (F₁), 75%N + 85%P₂O₅ + 85%K₂O + 75S% (F₂) and 100% NPKS (F₃) and seven liquid biofertiliser combinations i.e. control (B₀), Rhizobium (B₁), PSB+PMM (P-Solublizer & Mobilizer) (B₂), KMB (K-Mobilizer) (B₃), Rhizobium + PSB + PMM + KMB (B₄), SSB (S-solublizer) (B₅) and Rhizobium + PSB + PMM + KMB + SSB (B₆) were laid out in split plot design with three replication. Results showed that the dose of 50%N+75% P₂O₅+75%K₂O+50% S recorded highest nutrient use efficiency and apparent recovery and 75%N+85% P₂O₅+85%K₂O+75% S recorded highest factor productivity of nitrogen and Rhizobium + PSB + PMM + KMB + SSB recorded highest nutrient use efficiency and apparent recovery of N during both the years and in pooled analysis than control.
