1. Understand and apply principles of agronomy to various crops

1.2. dentify and Implement Appropriate Crop-Specific Management Practices

Chapter Title: Identify and Implement Appropriate Crop-Specific Management Practices


🎯 Learning Outcomes

By the end of this chapter, the learner should be able to:

  1. Identify management practices specific to different crop types.

  2. Understand the unique growth requirements and challenges of selected crops.

  3. Implement best practices for field management, input application, and harvesting.

  4. Adjust crop practices based on local conditions, crop stages, and climate.


📖 Chapter Notes


🔹 1. Crop-Specific Management Overview

Different crops require different care based on their growth habits, environmental needs, and sensitivity to inputs. A "one-size-fits-all" approach is ineffective.


🔹 2. Key Management Areas by Crop

Crop Specific Management Practices
Maize Timely weeding (2 & 6 weeks), top-dressing with CAN, pest scouting for stalk borer.
Beans Inoculation with Rhizobia, early planting, avoid waterlogging, disease-resistant varieties.
Tomatoes Staking, regular spraying (fungicides/insecticides), mulching, calcium supplements.
Rice Water level control (5–10 cm), puddling, uniform transplanting, rat control.
Cassava Spacing 1m x 1m, remove weeds regularly, harvest on time (9–12 months).

🔹 3. Stage-Based Crop Management

Growth Stage What to Manage
Germination Moisture, seed health, soil temperature
Vegetative Fertilizer topdressing, pest and weed control
Flowering & Fruiting Water stress, nutrient demand, pest scouting
Maturity & Harvest Drying down, proper timing, storage readiness

📝 Summary

Effective crop management is crop-specific and stage-specific. Understanding what each crop needs at each stage—from soil preparation to harvesting—ensures healthy growth and higher yields. Farmers must tailor their actions based on each crop's requirements and growing conditions.
