Describe the key agronomic practices required for successful cultivation of minor millets such as little millet, foxtail millet, kodo millet, and barnyard millet. How do these practices vary according to agroecological zones?
Successful cultivation of minor millets—little millet, foxtail millet, and kodo millet—requires specific agronomic practices tailored to their unique characteristics and growing requirements. Land preparation involves creating a fine, well-pulverized seedbed through 2-3 ploughings followed by planking to ensure proper seed-soil contact and uniform germination. Sowing should be done at optimal times (kharif season for most varieties) using line sowing or broadcasting methods with appropriate seed rates (3-4 kg/ha for little millet, 8-10 kg/ha for foxtail millet, and 10-12 kg/ha for kodo millet) at shallow depths of 1-2 cm. Nutrient management typically involves applying 40-60 kg N, 20-30 kg P₂O₅, and 20-30 kg K₂O per hectare, with organic matter incorporation to improve soil health and water retention. Water management focuses on providing adequate moisture during germination and grain filling stages, though these crops are generally drought-tolerant and require minimal irrigation compared to major cereals. Weed control is critical in the early stages through timely inter-cultivation operations or selective herbicide applications, as these small-seeded crops are initially slow-growing and vulnerable to weed competition. Integrated pest and disease management involves monitoring for common pests like shoot fly and stem borer, while maintaining proper plant spacing and avoiding excessive nitrogen to prevent lodging and disease incidence, ultimately ensuring healthy crop development and optimal grain yields.
