Effect of Rhizobium Inoculation with Different Levels of Inorganic Fertilizers on Yield, Nutrient Content & Uptake of Chickpea (Cicer arietinum L.)

The field experiment was conducted during Rabi season of 2021-22, to study the effect of combination of biofertilizer and different level of inorganic fertilizers on yield, quality, nutrient content & uptake of chickpea (Cicer arietinum L.) at pot culture farm of Department of Soil Science & Agricultural Chemistry of Chandra Shekhar Azad University of Agriculture & Technology, Kanpur (U.P.). The experiment comprises of eight treatments T1 (Control), T2 (RDF 75%), T3 (RDF 100%), T4 (RDF 125%), T5 (Rhizobium), T6 (RDF 75% + Rhizobium), T7 (RDF 100% + Rhizobium), T8 (RDF 125% + Rhizobium) in randomized block design with four replications. The chickpea variety RVG-202 is grown by adopting various agronomic practices. The result revealed that among all the treatments, RDF 125% + Rhizobium (T8) treatment recorded maximum yield, highest nutrient content in terms of % N(3.58 %), % P (1.34 %) and % K (0.69 %) in grain % N(2.38 %), % P (1.35 %) and % K (0.86 %) in stover. Highest nutrient uptake viz. N (65.69 kg ha-1), P (24.58 kg ha-1) and (12.66 kg ha-1) in grain and N (61.14 kg ha-1), P (8.99 kg ha-1) and (47.78 kg ha-1) stover is also associated with the treatment T8 [RDF 125% + Rhizobium]. It is clearly identified that seed inoculated with rhizobium can increase yield, nutrient content and uptake values of chickpea crop.
