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.

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 + Azotobacter 25g/kg + Potassium 30kg/ha, T8: Azospirillum + Azotobacter 25 g/kg + Potassium 40kg/ha, T9: Azospirillum + Azotobacter 25g/kg + Potassium 50kg/ha and T10: Control are used. The application of Azospirillum + Azotobacter 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.

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.
