Study Notes
Post-Harvest Management
- After harvesting, proper water management is essential to maintain soil moisture levels and prevent waterlogging.
- Water may be drained from the field to facilitate soil drying and decomposition of crop residues.
- Irrigation scheduling should be adjusted based on weather conditions and the moisture needs of the soil and upcoming crops.
Pest and Disease Management
- Monitoring paddy fields for pest and disease outbreaks is important after harvest to prevent damage to the next crop.
- Integrated pest management (IPM) practices, including cultural, biological, and chemical control methods, should be implemented as needed to manage pest and disease pressure effectively.
Crop Rotation
- Rotating rice with other crops in the cropping system helps break pest and disease cycles, improve soil health, and enhance overall crop productivity.
- Crop rotation options should be considered based on local agro-climatic conditions, market demand, and agronomic practices.
Direct Sowing Cultivation
- Direct sowing cultivation is a method that cultivates rice by sowing seeds directly in paddy fields without transplanting.
- Direct sowing methods include direct sowing in flooding paddy field and that in well-drained paddy field.
- Seeds coated with calcium peroxide (Calper) or iron are used to improve budding.
Sparse Planting
- Sparse planting is a cultivation method that reduces planting density by widening the intrarow spacing set by rice transplanters.
- Widening the interrow spacing from 15 cm to 28 cm can reduce the number of nursery boxes by more than 40%.
Rice for Livestock Feed
- Rice for livestock feed requires drying to reduce moisture content from 20-27% to 14-15% using heated-air.
- Brown rice is prepared by hulling, removing any rice fragments, and then packing in 30 kg rice bags and flexible containers.
Residue Management
- After harvesting, the remaining plant residues should be managed properly by incorporating them back into the soil through plowing or mulching.
- This helps improve soil organic matter content, enhances soil structure, and promotes nutrient recycling.
Weed Control
- Controlling weed growth is essential to prevent competition for resources and ensure the success of the next crop.
- Weed control methods may include manual removal, herbicide application, or mechanical cultivation.
Soil Preparation
- Paddy fields should be prepared for the next planting season by leveling the soil surface, breaking up soil clods, and ensuring proper drainage.
- This may involve plowing, harrowing, or using appropriate machinery to achieve a fine seedbed for planting.
Soil Testing and Fertilization
- Conducting soil tests after harvest helps assess nutrient levels and pH balance in the soil.
- Appropriate fertilization strategies can be implemented based on the nutrient requirements of the upcoming crop and local agronomic recommendations.
