Okra (Abelmoschus esculentus) is a nutrient-demanding crop that thrives in well-drained, fertile soils with a pH of 5.8–7.0. Proper organic nutrient management using Microbebio products, combined with effective pest and disease control, ensures optimal vegetative growth, flowering, and pod production. This guide provides a detailed schedule for ap- plying Microbebio organic fertilizers and pest/disease control measures across all growth stages to maximize okra yield (60–70 quintals/acre with proper care). Fertilizer applica- tions should be guided by soil tests to avoid nutrient imbalances, as excessive nitrogen can lead to excessive foliage at the expense of pods, while insufficient phosphorus or potassium can stunt root development and disease resistance.

Microbebio Fertilizer Schedule by Growth Stage

1.     Pre-Planting (Soil Preparation, Before Sowing)

Objective: Build soil fertility and provide a nutrient base for seedling establishment.

Organic Fertilizers:

• Microbebio Nature Vigor: Apply 15 kg/ha to enhance soil microbial activity and nutrient availability.
• Microbebio Rhizo Activator: Apply 75 kg/ha to promote root development and nutrient uptak
• Farmyard Manure (FYM) or Compost: Apply 8–10 tons/acre, well-rotted, 3– 4 weeks before planting to improve soil structure and provide slow-release nutrien

Application Method: Broadcast and incorporate into the soil 6–8 inches deep or apply in a band 2–3 inches below and to the side of the seed row to avoid root burn.

2.     Seedling Stage (0–3 Weeks After Planting)

Objective:  Support early growth and root establishment.

Organic Fertilizers:

• Formula AA: Mix 500 g Microbebio X1, X3, X5 + 8 L Hydro Activator + 15 kg Nature Vigor, diluted in 500 L non-chlorinated water/ha. Apply as a foliar spray every 8 weeks to boost nitrogen, micronutrients, and pest/disease

Application Method: Use foliar sprays for Formula AA to ensure rapid nutrient deliv- ery.

3.     Vegetative Growth (3–6 Weeks After Planting)

Objective: Promote strong vegetative growth and root development.

Organic Fertilizers:

• Formula AA: Continue 500 g Microbebio X1, X3, X5 + 8 L Hydro Activator + 15 kg Nature Vigor, diluted in 500 L non-chlorinated water/ha, every 8 weeks as a foliar spray.

4.     Flowering and Fruit Set (6–8 Weeks After Planting)

Objective: Enhance flower formation and pod development.

Organic Fertilizers:

• Formula AA: Continue 500 g Microbebio X1, X3, X5 + 8 L Hydro Activator + 15 kg Nature Vigor, diluted in 500 L non-chlorinated water/ha, every 8 weeks as a foliar spray.

Application Method: Foliar sprays for Formula AA ensure sustained nutrient delivery.

6.     Ratooning (Mid-Season for Extended Harvest, Optional)

Objective: Stimulate new growth and a second crop by cutting back plants.

Organic Fertilizers:

• Microbebio Rhizo Activator: Apply 75 kg/ha after cutting to replenish soil nutrien
• Compost or FYM: Apply 1–2 tons/ha post-cutting to support new gro

Application  Method:   Side-dress  Rhizo  Activator  and  compost/FYM  after  cutting plants to 6–12 inches, followed by irrigation.

General Notes on Fertilizer Application

• Soil Testing: Conduct soil tests every 2–3 years to determine nutrient deficiencies and adjust application
• Irrigation: Water after fertilizing to ensure nutrient uptake, especially for granular Use drip irrigation for precise delivery and to reduce foliar diseases.
• Organic Matter: Regular additions of compost or FYM, alongside Microbebio products, improve soil structure and long-term fertility, reducing nutrient deficien-
• Micronutrients: Ensure adequate calcium, magnesium, iron, manganese, and zinc to prevent deficiencies (e.g., yellowing leaves for nitrogen, purplish leaves for phosphorus, scorched leaf edges for potassium).

Pests, Fungi, Viruses, and Diseases by Growth Stage
