EXERCISE 3 Flashcards
Land Preparation And Field Practices For Lowland And Upland Crops (19 cards)
It is the mechanical manipulation of the soil resulting to soil tilth favorable for seed germination and plant growth
Tillage
What is the primary tillage for?
- to break the soil compaction
- resulting to soil clods
- plowing
What is the secondary tillage for?
- reduce soil aggregates
- level the soil surface
- harrowing and furrowing
What secondary tillage practice describes the following?
- Break-up clods (lump of soil)
- Finer finish
- Remove weeds
- Cover seeds after sowing
Harrowing
What secondary tillage practice describes the following?
- Create deep wide furrows at regular spacing
- Create planting spots
Furrowing
CHARACTERISTICS OF A WELL-PREPARED FIELD (GFL)
- Granular, mellow yet compact
- Free of trash/vegetation
- Level with minimum depression
WHAT ARE THE BENEFITS DERIVED FROM LAND PREPARATION? (EWWMI)
- Excellent condition for crop growth
- Weed control/management
- Water and soil conservation
- Modification of the microbial population in the soil
- Incorporation of OM
WHAT ARE THE TWO SYSTEMS OF LAND PREPARATION?
Lowland and Upland
What land preparation are usually grown in bunded fields for water retention?
Lowland
What land preparation use well-aerated soils?
Upland
What direct seeding method is done by evenly spreading seeds on top of the seedbed; can be manual or mechanized?
Broadcasting
What direct seeding method is sowing seeds in a row at a uniform depth in a seedbed using equipment; greater seeding precision?
Drilling
What direct seeding method refers to seeds are sown in more/less uniform distance; no land preparation needed; applicable in hilly areas?
Dibbling
METHODS OF RICE ESTABLISHMENT (DBRT)
Direct Seeding
Broadcasting seeding
Row seeding
Transplanting
What transplanting method facilitate management practices, optimal spacing?
Straight-row method
What transplanting method does this refer to?
Transplanted without a definite distance or space between plants (usually for large areas)
Random method
RICE SEEDLING METHODS (WDDS)
Wet bed
Dry bed
Dapog
Seedling boxes for mechanical transplanting
