“…High dry matter in those treatments is due to long plant height, high stem girth, and high root weights. These findings are in the harmony with those obtained by Marngar and Dawson [10] and Palai et al [11].…”

The study aims to highlights the effect of different biofertilizers and zinc levels on growth and yield of maize (Zea mays. L). The study was conducted during Rabi 2021 at crop Research farm, Department of Agronomy, SHUATS, Prayagraj, (U.P), India. The soil of this experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), in low organic carbon (0.36%), available N (171.48 kg/ha), available P (15.2kg/ha), available K (232.5 kg/ha). This experiment was performed in Randomised Block Design with nine treatments each replicated thrice on the basis of one-year experimentation. The treatments which are T1: Azospirillum+ZnSo4 10 kg/ha, T2: Azospirillium+0.1% ZnSo4, T3: Azospirillum+0.2% ZnSo4, T4: Azotobacter + ZnSo4 10 kg/ha, T5: Azotobacter + 0.1% ZnSo4, T6: Azotobacter + 0.2% ZnSo4, T7: Azotobacter + Azospirillum + ZnSo4 10 kg/ha, T8: Azotobacter + Azospirillum + 0.1% ZnSo4, T9: Azotobacter + Azospirillum + 0.2% ZnSo4. The results showed that application of Azotobacter + Azospirillum + 0.2% ZnSo4 was recorded significantly higher Plant height (195.29 cm), Plant dry weight (183.65 g/plant), Whereas significantly highest crop growth rate (5.31 g/m2/day) was recorded with the treatment Azospirillum + ZnSo4 10 kg/ha. Significantly maximum Cobs/plant (2.60), Cob length (27.17 cm), Rows/cob (15.19), Grains/cob (30.16), weight of grains/cob (140.88 g), seed index (230.66), Cob yield (6.33 t/ha), Stover yield (14.30 t/ha), Harvest index (30.67%), Gross returns (Rs.107553.00/ha), Net returns (Rs.71570.00/ha) and Benefit cost ratio (1.99) were obtained with application of Azotobacter + Azospirillum + 0.2% ZnSo4 as compared to other treatments.

The experiment was conducted in CRF in Department of Agronomy during summer season of 2022 on Maize crop. The aim was to study the effect of soil application of zinc and foliar application of boron and growth and yield of maize. The Treatments consisted of 3 levels of Zinc (5,10 and 15 kg/ha) and Boron (0.5, 1 and 1.5%) as foliar spray and a control. The experiment was laid out in a Randomized Block Design (RBD) with Ten treatments each replicated thrice. Application of 15 kg Zinc with Boron 1.5% as foliar spray recorded highest Plant height (209.16 cm), No. of Leaves/plant (12.83), Plant dry weight (183.65 g/plant), No. of Cobs/plant (2.33), No. of Grains/Cob (523.93), No. of row/cob (14.74), No. of Grains/row (41.53), Test weight (27.5g), Grain yield (6.33 t/ha), Stover yield (14.30 t/ha) Harvest Index (30.7%).

“…Soil application of zinc sulphate @ 37.5 kgha -1 with 0.5% foliar spray at 20 and 40 DAS recorded a higher NAR with an increment of 14.7% and 28.2% between 25 DAS and 45 DAS and between 45 DAS and harvest stages, respectively. The experimental results are in accordance with the findings of Palai et al (2017) who reported that the higher rate of zinc applied as seed priming and foliar spray @ 2% gave maximum NAR.…”

“…It is obvious because of the favourable effect of zinc application on production of higher babycorn and green fodder yield as well as remunerative returns in spite of higher cost of cultivation. Palai et al (2018) found that the highest net return ( �165442 ha -1 ) was observed with soil application of Zn @ 6 kgha -1 along with foliar spray @ 0.05% Zn at 25 DAS with seed treatment @ 0.6% Zn. The B:C ratio was also highest (4.46) in soil application of Zn @ 6 kgha -1 along with foliar spray @ 0.05% Zn at 25 DAS.…”

A field experiment was conducted during late Kharif (September-November) of the year 2018 at Eastern Block Farm, Tamil Nadu Agricultural University, Coimbatore to find out the effect of agronomic bio-fortification with zinc on physiological parameters, nutrient uptake, yield and economics of babycorn under irrigated condition. The field experiment was laid in randomized complete block design with three replications. The treatments comprised of T1: No zinc (control), T2: Zinc Sulphate (ZnSO4) at 25 kgha-1 as soil application, T3: ZnSO4 at 37.5 kgha-1 as soil application, T4: Foliar spray of ZnSO4 at 0.5% on 20 and 40 DAS, T5: Foliar spray of ZnSO4 at 1.0% on 20 and 40 DAS, T6: ZnSO4 at 25 kgha-1 as soil application + foliar spray at 0.5% on 20 and 40 DAS, T7 : ZnSO4 at 25 kgha-1 as soil application + foliar spray at 1.0% on 20 and 40 DAS, T8: ZnSO4 at 37.5 kgha-1 as soil application + foliar spray at 0.5% on 20 and 40 DAS, T9: ZnSO4 at 37.5 kgha-1 as soil application + foliar spray at 1.0% on 20 and 40 DAS. Babycorn hybrid G-5414 was used to experiment with a plant spacing of 45 cm x 25 cm. The results showed that the combined application of zinc sulphate @ 37.5 kgha-1 with 0.5% foliar spray at 20 and 40 DAS recorded significantly higher Crop Growth Rate (CGR) (31.07, 30.83) gcm-2day-1, Relative Growth Rate (RGR) (110.25, 31.67) mgg-1day-1 and Net Assimilation Rate (NAR) (9.65, 4.54) mgcm-2day-1 at 25-45 DAS and 45 DAS - harvest intervals respectively. NPK uptake was recorded higher in (T8) and green cob yield was recorded higher in (T9) at harvest stage. Green fodder yield and higher benefit cost ratio was obtained higher with soil application of zinc sulphate @ 37.5 kgha-1 with 0.5% foliar spray at 20 and 40 DAS.
