Impact of Organic Manures and Foliar Spray of Moringa Leaf Extract (Moringa oleifera L.) on Growth and Yield of Rice Bean [Vigna umbellata (Thunb.) Ohwi and Ohashi]

A field experiment on rice bean was conducted during Kharif, 2021 at SMOF (SHIATS Model Organic Farm), Department of Agronomy, SHUATS, Prayagraj (U.P), India. The soil of the experiment plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.2), low in organic carbon (0.51%), available nitrogen (230 kg/ha), available phosphorus (17.80 kg/ha) and available potassium (245.10 kg/ha). The foliar spray of Moringa oleifera L. extract was applied twice at different concentrations (5.0, 10.0 and 20.0% v/v) with different organic manures (pig manure, goat manure and neem cake) applied at 5 t/ha and control plot with water spray. The experiment was laid out in Randomized Block Design with ten treatments each replicated thrice. As compared to other treatments, the results disclosed that application of neem cake 5t/ha + 20% moringa leaf extract recorded highest plant height (105.78 cm), nodules per plant at 60 DAS (35.64), branches per plant (20.61), plant dry weight (35.01 g/plant), pods per plant (25.85), seeds per pod (7.45), test weight (50.52 g), seed yield (1.66 t/ha), stover yield (3.72 t/ha), harvest index (30.86 %). Therefore, application of neem cake and foliar application of Moringa oleifera L. might be a promising option for yield enhancement of rice bean

Influence of Bio-fertilizers and Potassium Levels on Growth and Yield of Pearl Millet (Pennisetum glaucum L.)

A research study was carried out at Crop Experimental Farm, Department of Agronomy, SHUATS, Prayagraj, for the duration of Kharif 2021 (U.P). The topsoil of the experimental area was sandy clay loam, nearly fair and balanced in soil properties (pH 7.1), low in organic material (0.36 %), obtainable N (171.48 kg/ha), obtainable P (15.2 kg/ha), and obtainable K (232.5 kg/ha). The experiment has been conducted in Randomized Block Design, as well as the 10 treatment options replicated three times over a period of a year. The treatments which are T1: Azospirillum 25g/kg + Potassium 30kg/ha, T2: Azospirillum 25g/kg + Potassium 40 kg/ha, T3: Azospirillum 25g/kg + Potassium 50kg/ha, T4: Azotobacter 25g/kg + Potassium 30kg/ha, T5: Azotobacter 25g/kg + Potassium 40kg/ha, T6: Azotobacter 25g/kg + Potassium 50kg/ha, T7: Azospirillum (12.5g/kg) + Azotobacter (12.5g/kg) 25g/kg + Potassium 30kg/ha, T8: Azospirillum (12.5g/kg) + Azotobacter (12.5g/kg) -25 g/kg + Potassium 40kg/ha, T9: Azospirillum (12.5g/kg) + Azotobacter (12.5g/kg) -25g/kg + Potassium 50kg/ha and T10: Control are used. The application of Azospirillum (12.5g/kg) + Azotobacter (12.5g/kg)- 25 g/kg + Potassium 50 kg/ha resulted in significantly higher plant height (150.25 cm), number of leaves/plant (12.65), plant dry weight (17.19 g/plant), number of ears/hill (2.60), number of grains/ear (2420.73), test weight (9.45 g), grain yield (3.16 t/ha), straw yield (7.57 t/ha). Harvest index (29.40), gross returns(Rs.79,000/ha), net returns(Rs.48,878.20/ha) and benefit cost ratio (1.62) as compared to other treatments

Effect of Nitrogen and Zinc Levels on Growth and Yield of Black Gram (Vigna mungo L.)

To study the retaliation performance of Nitrogen and Zinc on growth, yield and yield attributes of black gram (Vigna mungo L.) During the Zaid season of 2021, a field experiment was carried out at the agricultural research farm of SHUATS, Prayagraj, to analyze the influence of nitrogen and zinc levels on the growth and yield of a Black gram. The experiment was conducted in a randomized block design (RBD) it was carried with Nine treatments, each treatment have three replications and we observed each treatment on the bases of one-year experimentation. In view of this experiment three Nitrogen levels, i.e.N1 - (15 kg/ha), N2 – (20 kg/ha) and N3 – (25 kg/ha) and Zinc levels, i.e., Zn1 – (0.25 %), Zn2 – (0.5 %), Zn3 – (0.75 %) .The results was obtained that the treatment with the application of N 25 kg/ha+ Zn 0.5% was observed significantly maximum plant height (41.50 cm), number of nodules per plant (25.50), number of branches per plant (7.65), plant dry weight (9.61 g/plant), pods per plant (37.55), seeds per pod (6.83), test weight (39.23 g), grain yield (937 kg/ha), stover yield (2418 kg/ha). Maximum net return (Rs42008.92/ha) and B:C ratio (2.22) were recorded with treatment of N 25 kg/ha+ Zn 0.5%.This study concluded that the maximum grain yield (937 kg/ha) was acquired with application N 25 kg/ha+ Zn 0.5%, significantly superior to the rest of the treatments

Potentiality of Biofertilizers and Seaweed Extract on Growth & Yield of Sweet Corn (Zea mays L.)

The study aimed to understand and study the effect of commercial seaweed extract and other biofertilizers on the yield attributes and economics of cultivated sweet corn. The biofertilizers were applied as seed inoculants and seaweed extract was applied as foliar spray. Totally nine combination treatments were evaluated for their performance on the growth and yield of sweet corn and revealed that green cob yield (10.58 t/ha and plant height 145.99 cm at harvest ) was found to be significantly higher in treatment combination Azospirillum @10 gm/kg + PSB @10 gm/kg +5.0% Seaweed extract  and was on par with Azospirillum @20 gm/kg +5.0% Seaweed extract (9.61 t/ha, plant height 143.01 cm). Cobs/plant, grains rows/cob, grains /cob and grains/row were also found highest in the treatment Azospirillum @10 gm/kg + PSB @10 gm/kg +5.0% Seaweed extract. Similarly with respect to stover yield and higher harvest index (34.50%) was noticed in PSB @20 gm/kg +10% Seaweed extract which was followed by Azospirillum @10 gm/kg + PSB @10 gm/kg +5.0% Seaweed extract (34.40%). The benefit cost ratio was highest in the treatment  Azospirillum @10 gm/kg + PSB @10 gm/kg +5.0% (2.77) and lowest B:C ratio (1.2) was obtained in the PSB @20 gm/kg + water spray. These findings indicate that seaweed extract can generally be used as a safe potential multifunctional biofertilizer in the agricultural field. The use of seaweed and biofertilizer could potentially help mitigate the adverse effects of main nutrient deficiencies, diminishing the use of chemical fertilizers
