ABSTRACT
Due to high yielding and short duration hybrid pearl millet got populized in last few years under pearlmillet-mustard/wheat cropping system but its required higher nutrient as compared to composite varieties but farmers apply only N and little amount of P which is responsile for low yield therefore, the present study was carried out during kharif 2021 and 2022 with 12 treatments of different sources which are chemical fertilizers, vermicompost (VC) and bio-fertilizers(Azotobacter and PSB) and application methods (seed treatment, soil and foliar application) of nitrogen and phosphorus in RBD with 3 replications. The resulted indicated that the application of 100% Nitrogen and Phosphorus by chemical fertilizers produced significantly higher yield attributes (length and girth of cobs) and yield parameter (grain and stover yield and harvest index) of pearlmilletas compared to 50 and 75% NP treatments. Maximum grain yield 29.87 q ha-1) was noted with integration of chemical, organic and bio fertilizers (75% NP + Seed treatment by Azoto + PSB + 5 t VCha-1) which was significantly higher over rest of all other treatments. Minimum yield parameters were noted with control (0 % NP). Application of vermicompost @ 5 t ha-1 with 75 per cent of NP and inoculation of Azotobacter and PSB improved test weight and protein content.
ABSTRACT
This study was carried out during March – June 2022 on vegetable research farm Department of Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj. The objective of the experiment was to screen out the best combination of biofertilizer and inorganic manures for growth, yield, and quality of okra and to work out the economics. The design of the experiment was randomized block design (RBD) with three replications. The result shows that T8 75%N + 100%PK + Azotobacter + Azospirillum + PSB was found superior in terms of plant height (9.30cm in 20 days, 30.23cm in 40 days, 43.58cm in 60 days), plant spread (19.94cm2 in 20 days, 34.64 cm2 in 40 days, 60.74 cm2 in 60 days), days to first flowering (33.98 days), days to 50% flowering (42.43days), days to fruit setting (46.95 days), days to first fruit picking (48.68 days), fruit weight (9.83g), length of fruit at marketable stage (13.10cm), girth of fruit (2.02cm), no. of fruit per plant (23.98/plant), no. of seeds per fruit (48.39), fruit yield per plant(g) 235.65g, fruit yield per plot (kg) 7.78kg, fruit yield (t/ha) 19.44, TSS (14.61oBrix), ascorbic acid (21.31 mg/100g). Net economic returns of treatment were highest in T8 (75%N + 100%PK + Azotobacter + Azospirillum + PSB) Rs.472592.83 with highest cost benefit ratio of (4.27).

ABSTRACT
A field experiment was conducted during Zaid 2023 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to determine the “Effect of Different levels of Nitrogen and Seed treatment on growth and yield of finger millet (Eleusine coracana L.)”. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.8), low in organic carbon (0.62%), available nitrogen (225 kg/ha), available phosphorus (38.2 kg/ha) and available potassium (240.7 kg/ha). The treatments consisted of three levels of [Nitrogen 40 kg/ha, 50 kg/ha, 60kg/ha] and three types of Bio-fertilizers [Azospirillum 2 g/kg, Pseudomonas fluorescens 6 g/kg, Azotobacter 3 g/kg] as seed treatment, whose effect is observed in finger millet. The results revealed that the treatment with application of Nitrogen 60 kg/ha + Azospirillum 2 g/kg recorded higher plant height (86.27 cm), number of tillers/plant (8.67/plant), plant dry weight (23.41 g/plant), higher test weight (2.92 g), number of fingers/plant (5.67), number of ear heads/plant (3.32), number of grains/fingers (114.14), grain yield (2,635.65 kg/ha), straw yield (4,883.10 kg/ha) and Harvest index (35.05%).The economics viz., maximum gross returns (1,05,426.00 INR/ha), net returns (67,577.00 INR/ha) and B:C (1.78) was also recorded in treatment 7 [Nitrogen 60 kg/ha + Azospirillum 2 g/kg] as compared to other treatments.
ABSTRACT

India. The experiment was laid out in Randomized Block Design with ten treatments replicated thrice. The treatment combinations are T1:Azotobacter 25g + Zinc 0.1% (30 DAS and 50 DAS) T2:Azotobacter 25g + Zinc 0.3% (30 DAS and 50 DAS) T3: Azotobacter 25g + Zinc 0.5% (30 DAS and 50 DAS) T4:Azospirillum 25g + Zinc 0.1% (30 DAS and 50 DAS) T5:Azospirillum 25g + Zinc 0.3% (30 DAS and 50 DAS) T6:Azospirillum 25g + Zinc 0.5% (30 DAS and 50 DAS) T7:Azotobacter + Azospirillum 25g +Zinc 0.1% (30 DAS and 50DAS). T8:Azotobacter + Azospirillum 25g +Zinc 0.3% (30 DAS and 50 DAS) T9:Azotobacter+ Azospirillum 25g +Zinc 0.5% (30 DAS and 50 DAS), T10: Control (RDF-80-40-40 NPK kg/ha) are used. Results obtained that the higher plant height (205.06 cm), higher plant dry weight (78.17 g/plant), higher crop growth rate (37.6 g/m2 /day), higher ear head length (24.74 cm), higher grains/ear head (2212.69), higher test weight (10.29 gm), higher grain yield (34.16 q/ha) and higher stover yield (69.00 q/ha) were significantly influenced with application of Azotobacter+ Azospirillum 25g +Zinc 0.5% (30 DAS and 50 DAS). Higher gross returns (INR 96553.67/ha), higher net returns (INR 67523.67/ha) and higher B:C ratio (2.03) were also recorded in treatment-9 (Azotobacter+ Azospirillum 25g +Zinc 0.5% (30 DAS and 50 DAS).
ABSTRACT
The present study conducted entitled, “Effect of Integrated use Organic manure and Bio-fertilizers on crop productivity under Rice (Oryza sativa L.) crop". Involved field trial conducted during Kharif season of year 2016-17 followed by laboratory analysis of the plant and soil samples in the Department of Soil science & Agriculture Chemistry, Udai Pratap Autonomous College, Varanasi (U. P). All grasses were removed from the experimental plots and soil samples have been taken from each replication plots at 30 DAT, 60 DAT and at harvesting. The experiment was conducted under randomized block design (RBD) with six treatment combinations. Treatments were replicated thrice making the total number of 18 plots. The effect of various treatments on dry matter production could be arranged in order of T6>T3>T5>T4>T2>T1 and the values were 70.25, 62.15, 59.45, 43.40, 41.25 and 35.59 gm-1 row length, respectively. Application of fertilizers alone or in combination with F.Y.M increased grain and straw yield of rice significantly over control. Further, the yield was significantly superior under the use of organic manure and bio-fertilizers over the sole use of chemical fertilizers. On the basis of data, the superiority of the treatments may be arranged as T6>T3>T5>T4>T2 and T1. Like dry matter yield, rice grain and straw yield was also highest in treatment where 50% NPK was substituted through FYM to rice crop. The integrated use of fertilizers with FYM and bio-fertilizers might have added huge quantity of organic matter in soil that increased grain and straw yield. In general, higher number of tillers (15.25 m-1 row length), plant height (92.50 cm), dry matter at 60 DAT (70.25 gm-1 row length), grain yield (46.25 Qha-1 ) and straw yield (91.25 Qha-1 ) obtained with T6 treatment followed by T3>T5>T4>T2>T1 (control).
