The present field experiment was conducted during the Rabi season of 2020-21 and 2021-22 at the Student's Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh. The experiment comprised of 18 treatment combinations in Factorial randomized block deign with three replications. The result shown among the growth parameters the following assessed data: maximum plant height (48.56 cm) at 90 DAS, the number of nodules (31.27) at 60 DAS, dry weight of nodules (185.77 mg) at 60 DAS and the number of branches (18.12), similarly among yield attributes and yield viz. number of pod plant-1 (69.54), number of grains pod-1 (1.78), 100 grain weight (20.19 gm), grain yield (20.89 q ha-1) and stover yield (25.26 q ha-1) were recorded under T18 (P60+Zn2.5+ rhizobium) during the second year (2021-22) of experimentation. The application of phosphorous, zinc and rhizobium inoculation significantly increase growth, yield and yield attributes of chickpea during the both years of experiments. The present study shown that application of phosphorus, zinc and rhizobium inoculation along with recommended nitrogen and potassium could been an effective option for enhancing the chickpea growth parameters, yield attributes and yield of chickpea.

The current field experiment was carried out during Rabi season of 2020-21 and 2021-22 at the Student's Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh to assess the Studies on the root architecture with nodulation of the chickpea (Cicer arietinum L.) as influence by different moisture management practices along with seed inoculation and level of zinc. The experiment was laid out in split-split plot design with 27 treatment combination comprising three moisture conservation practices namely, flat bed with 2.5 t/ha crop residue, narrow bed and furrow with 2.5 t/ha crop residue, broad bed and furrow with 2.5 t/ha crop residue in main plot and three seed inoculation (control, rhizobium and PSB) in sub-plots and three zinc level (control, 2.5 kg zinc/ha and 5.0 kg zinc/ha) in sub- sub plot with three replication. Results showed that among the different moisture management practices, used of broad bed and furrow with 2.5 t/ha crop residue were significantly enhanced root architecture, nodulation and grain yield, over the flat bed with 2.5 t/ha crop residue, respectively. Among the different Biofertilizers treatments seed inoculation with Rhizobium had significantly improved the root architecture, nodulation and yield, over control. Application of increasing levels of zinc up to 5.0 kg Zn/ha has significant influences on root architecture, nodulation and yield, over control. The combined application broad bed and furrow with 2.5 t/ha crop residue with Rhizobium and 5.0 kg/ha zinc resulted in significantly higher root architecture, nodulation and seed yield of chickpea during both the years of experimentation.

A field experiment was conducted during the Rabi season of 2020-21 and 2021-22. The experiment was laid out in split-split plot design with 27 treatment combination comprising of three moisture conservation practices viz. flat bed with 2.5 t/ha crop residue, narrow bed and furrow with 2.5 t ha-1 crop residue and broad bed and furrow with 2.5 t ha-1 crop residue in main plot and three seed inoculation viz. control, rhizobium and PSB in sub plot with three zinc level viz. control, 2.5 kg Zn ha-1 and 5.0 kg Zn ha-1 in sub-sub plot. Result shows that the broad bed and furrow with 2.5 t ha-1 crop residue produced significantly all growth parameters and yields attributes as compare to flat bed with 2.5 t ha-1 crop residue and narrow bed and furrow with 2.5 t ha-1 crop residue, respectively. The all growth parameters and yields attributes were significantly recorded higher under seed inoculation with rhizobium over PSB and control. The application of different dose of zinc produced marked significant variation in growth parameter and yield attributes when it increased up to 5.0 kg Zn ha-1. The highest yields were significantly receive in broad bed and furrow with 2.5 t ha-1 crop residue over narrow bed and furrow with 2.5 t ha-1 crop residue and flat bed with 2.5 t ha-1 crop residue, respectively with percent increment 16.33, 24.65, 11.47 and 7.16 in respect of biological yield, grain yield, stover yield and harvest index, respectively over control in pooled data. Seed inoculation with rhizobium produced significantly higher yields parameter over control and PSB with percent increment 5.37, 7.72, 3.84 and 2.34 in biological yield, grain yield, stover yield and harvest index, respectively over control. Application of 5.0 kg Zn ha-1 were produced significantly higher yields with percent increment 6.24, 7.25, 5.56 and 1.01 over control in respect of biological yield, grain yield, stover yield and harvest index, respectively. Therefore, broad bed and furrow with 2.5 t ha-1 crop residue and rhizobium inoculation with dose of 5.0 kg Zn ha-1 were significantly superior in respect to growth and yield attributes and yields of chickpea in present investigation.
