A field experiment was conducted at the Department of Soil Science and Agriculture Chemistry, CoA, JNKVV, Jabalpur, during Rabi season 2021–22 to investigate the effect of Integrated Nutrient Management (INM) on chickpea production. The experiment involved three replications and three main treatments: 0% NPK at 20:60:20 kg ha-1, 50% NPK at 20:60:20 kg ha-1, and 100% NPK at 20:60:20 kg ha-1. Six sub-treatments of vermicompost plus biofertilizer treatments were also tested: T1vermicompost + (Rhizobium + PSB), T2 vermicompost + (Rhizobium + KSB), and T3 vermicompost + (Rhizobium + PSB + KSB), T4 vermicompost + (Rhizobium + PSB + KSB + Trichoderma), T5 vermicompost + (Rhizobium + PSB + KSB + Trichoderma + Pseudomonas), and T6 (control) have the same effect on the productivity of chickpeas. The results showed that different variations in vermicompost and biofertilizer had different effects on chickpea plant height, nodules in plant-1, chlorophyll content in leaves, and pod plant -1 at harvest. The highest response was observed in 100% NPK + VC + (Rhizobium + PSB + KSB + Trichoderma + pseudomonas), with a maximum response of 28.51 pods plant-1, 25% more than the control. The seed and straw yield of chickpea in 100% NPK + VC + (Rhizobium + PSB + KSB + Trichoderma + pseudomonas) was also significantly higher, with 18.41 qha-1, 28% more than the control.

Chlorophyll, Pseudomonas, Rhizobium, Vermicompost etc

The treatments of NPK 100+ VC+ Rhizobium +PSB+ KSB+ Trichoderma+ pseudomonas influence almost every parameter under study. This seemed to indicate that co-inoculation with different microbial cultures performed better than that of individual ones; application of the microbial consortia positively influenced parameters like plant height, nodulation, chlorophyll content, number of pods, seed yield, and straw yield.
