A field trial was conducted on sandy loam soil having low status of organic carbon and accessible nitrogen, medium in accessible phosphorous and high in accessible potassium at pot house of department of Soil Science and Agricultural Chemistry of C.S.A.U.A&T, Kanpur (campus) under Indo-Gangetic Plain zone of Uttar Pradesh, amid Rabi season of 2018-19. The experiment comprised of 5 treatment combinations in randomized block design with four replications consisted of T1: [Control], T2: [100% RDF], T3: [75% RDF + FYM at 6 t ha-1], T4: [50% RDF + FYM at 12 t ha-1], T5: [25% RDF + FYM at 18 t ha-1]. Wheat variety PBW-343 was grown with the recommended agronomic practices. On the premise of the comes about exuded from the present investigation, it might be concluded that application of 25% RDF + FYM at18 t ha-1 significantly recorded maximum nutrient content viz. N, P and K content in grain is 1.97%, 0.25% and 0.36% respectively and N,P, and K content in straw is 0.32%, 0.064% and 1.76% respectively. Maximum nutrient uptake viz. N, P and K uptake in grain is 86.58 %, 10.77% and 5.85% respectively and N, P, and K uptake in straw is 22.98%, 4.16% and 1.76 % respectively. Among the quality traits maximum protein content (11.78 %) was also associated with application of 25% RDF + FYM at 18 t ha-1. The present investigation clearly points out the significance of balanced use of nutrients including FYM in wheat for improving the nutrient content and uptake indices and quality of wheat crop.

The present field experiment was conducted during Rabi season of 2017–18 at the Student's Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh to evaluate the effect of different fertility levels and biofertilizers on growth parameters, root architecture and quality of late sown chickpea (Cicer arietinum L.). The experiment comprised of 12 treatment combinations in split plot design which comprised 4 treatments [F1 (control), F2 (RDF 100%), F3 (75% RDF), F4 (50% RDF)] in main plot and 3 treatments [B1 (Rhizobium + PSB), B2 (Rhizobium + PGPR) and B3 (Rhizobium + PSB + PGPR)] in sub plots with three replications. Results showed that among the different fertility levels, application of 100% RDF significantly enhanced growth parameters, root architecture and protein yield over the control. Among the different biofertilizers treatments application of Rhizobium + PSB + PGPR had significantly improved growth parameters, root architecture and protein yield as compared to Rhizobium + PGPR. The combined application of 100% RDF with Rhizobium + PSB + PGPR resulted in significantly higher growth parameters, root architecture and protein yield of late sown chickpea during winter (Rabi).

Maize (Zea mays L.) is one of the most important cereal crop, next to rice and wheat and is used as a food for human and feed for animals. This crop has been developed into a multi dollar business in countries viz. Thiland,

Field experiments were conducted to studies effect of integrated nutrient management on growth parameters, yield components and yield of wheat during rabi season of 2020-21 and 2021-22 at students instructional farm, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur. The experiment consist of 10 treatments combinations in randomized block design with three replications consisted of different combination of inorganic fertilizer, organic manure and biofertilizer. Wheat variety HD-2967 was grown with the recommended agronomic practices. On the basis of results emanated from investigation it can be concluded that among the growth parameters maximum plant height at maturity was 109.25 cm and 110.12, maximum number of effective tillers is 352.67 and 355.72 and maximum spike length is 13.55 cm and 13.79 cm are associated with the treatment T10 [100%NPK + FYM + S30+ Zn5 +Azotobacter + PSB] during the both years of experimentation. Similarly, among the yield components and productivity parameters maximum values in relation to number of spikelet ear-1, grain ear-1, 1000 grain wt. (gm), grain yield (q ha-1) and straw yield (q ha-1) were found in the treatment T10 [100%NPK+FYM+S30+Zn5+Azotobacter+ PSB].

A field experiment was conducted on student instructional farm (SIF) of Chandra Shekhar AzadUniversity of Agriculture and Technology, Kanpur, U.P. during kharif season 2019 and 2020, the present experiment having 32 treatments replicated thrice in factorial randomized block design on same laid out at same location. Hybrid maize variety Pioneer 3377 was sown at 60 × 20 cm (row×plant) during both the years, Soil application of Zinc (5.0 kg) and Iron (10 kg) along with 2.5 tonne vermicompost ha-1 gave significant increase (except plant population) in plant population m-2 (9.23 & 9.26), Plant height (195cm & 198 cm), number of cobs plant-1 (1.80 & 1.82), number of cobs m-2 (18 & 18) over control during 2019 and 2020.

The improvement in grain yield characters was the manifestation of improved growth characters as a result of higher uptake of nutrients caused by balanced supply of nutrients in this regard soil test based nutrient management approaches aims provide a scientific basis for balanced fertilization to obtain more yield per unit of fertilizer investment. An experiment was conducted during kharif season 2017-18 in the Soil Science and Agricultural Chemistry Research Farm, SHUATS, Prayagraj. The cursory glance of data revealed that the bulk density and particle density of soil was found to be non-significant in different levels of fertilizer recommendation based on soil test values. The maximum soil pore space (60.37%) and water retaining capacity (81.25 %) was recorded in treatment T4 [STCR + 5 t FYM]. The maximum available Nitrogen (305.82 kg ha-1), available Phosphorus (26.90 kg ha-1), available Potassium (205.07 kg ha-1) and available Sulphur (14.23 ppm ha-1) in soil was recorded in treatment T8 [STCR + @ 50 % FYM + @ 50 % S]. The maximum seed yield of mustard (11.53 q ha-1) and stover yield (16.03 q ha-1) was associated with the treatment T8 [STCR + @ 50 % FYM + @ 50 % S]. Result showed that that application of T8 [STCR + @ 50 % FYM + @ 50 % S] significantly recorded maximum nutrient content viz. N (2.19%), P (0.23%), K (1.68%) and S (4.8%) content in grain N (1.73%), P (0.21%), K (1.47%) and S (3.9%) content in stover and maximum nutrient uptake viz. N (25.25 kg ha-1), P (2.65 kg ha-1), K (19.37 kg ha-1) and S (55.34 kg ha-1) uptake in grain is and N (27.73 kg ha-1), P (3.36 kg ha-1), K (23.56 kg ha-1) and S (62.51 kg ha-1) uptake in stover.

P. during kharif season 2019 and 2020, the present experiment having 32 treatments replicated thrice in factorial randomized block design on same laid out at same location. Hybrid maize variety Pioneer 3377 was sown at 60 × 20 cm (row×plant) during both the years, Soil application of Zinc (5.0 kg) and Iron (10 kg) along with 2.5 tonne vermicompost ha -1 gave maximum increase in yield attributing characterstics viz. cob length (19.25cm & 19.80 cm), cob girth (13.60cm & 13.95 cm), number of grain row cob -1 (17 & 17), number of grain row -1 (33 & 35), test weight (24.10 gm & 24.30 gm) in comparison to all the treatments during 2019 and 2020.

A field experiment was conducted on Pot culture house of Department of Soil Science and Agricultural Chemistry at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during the rabi season 2016-17, In the present experiment 8 treatments  T1 (Control), T2 (100% RDF Recommended dose of fertilizer) , T3 (100% RDF+S30), T4 (100% RDF+Zn5), T5 (125% RDF), T6(125% RDF+S30 ), T7 (125% RDF+Zn5), T8 (150% RDF), were laid out in Randomized Block Design(RBD) with four replications. Mustard variety Pusa Bold was taken for study. The results revealed that the Yield (grain and stover yield) and their attributing characterstics of mustard respond significantly with the different treatment combination. The highest grain (20.11 q/ha) and stover yield (43.13 q/ha) was obtained in T7 (125% RDF+Zn5) . The treatment T7 cause 32.72 % increase in mustard grain yield and 14.22% increase in stover yield over control.. The treatment combination T7 (125% RDF+Zn5) gave the best result in terms of yield and their attributing characterstics.
