Study Notes
Exam Preparation Tips
- Understand exam format: number of questions, time limit, and guidelines.
- Ensure a reliable internet connection and use an appropriate device (computer, laptop, tablet).
- Choose a quiet, distraction-free environment for taking the exam.
- Gather all necessary materials like pens, pencils, and scratch paper (if allowed).
- Access exam link through the designated platform and log in if required.
- Familiarize with the exam interface, including navigation and answer review options.
- Carefully read each question and review all answer options prior to selection.
Crop Science Knowledge
- Cereal crops include corn and wheat, distinguishing them from fruits like apples and peanuts.
- Monocot example: Zea mays (corn), contrasted with dicots such as Glycine max (soybean).
- Chlorophyll's role: absorbs light energy, essential for photosynthesis.
- Phloem tissue function: transports sugars, as opposed to water or food storage.
- Topsoil is identified as the A horizon in soil profiles.
Agriculture Practices
- Integrated farming systems combine livestock and crop production, enhancing sustainability.
- Aquaponics systems raise fish and plants simultaneously, promoting efficient farming practices.
- Durio zibethenus refers to the durian fruit, whereas Annona squamosa is known as sugar apple.
- Coffee varieties: Coffea arabica is a plantation crop; Coffea robusta is also known as Nescafe coffee.
- Heirloom varieties in tomatoes include Brandywine and Mortgage Lifter, excluding Rome tomato.
Plant Genetics and Growth
- Homozygous refers to having two identical alleles for a specific gene.
- C3, C4, and CAM plants demonstrate varying adaptations to environmental conditions.
- Macronutrients essential for plant growth include nitrogen.
- Leguminous crops are valued for their nitrogen-fixing abilities, improving soil health.
Environmental Factors in Agriculture
- Absolute drought is defined as 15 or more consecutive days without rainfall.
- El Niño years typically result in water stress and reduced growth due to drought.
- Edaphic factors pertain to soil-related conditions affecting plant growth.
- Adaptations in CAM plants include stomata that open at night, reducing water loss.
Plant Reproduction and Breeding
- Sexual reproduction in plants increases genetic diversity compared to asexual methods.
- Grafting techniques include cleft grafting, bud grafting, and whip and tongue grafting.
- Silage is fresh forage that is preserved by fermentation for livestock feed.
- Iron deficiency often manifests as yellowing leaves in plants, indicating potential nutrient shortages.
Crop Cultivation Insights
- Rice seedlings should be transplanted at a depth of 1-2 cm for optimal growth.
- Irrigation method for water conservation: drip irrigation or alternate wetting and drying (AWD).
- Key regions for specific crops: Davao Region is known for Cavendish bananas in the Philippines.
- Best planting material for soybeans (Glycine max) is seeds.
Miscellaneous
- The Secretary of Agriculture for the Philippines was installed on November 3, 2023.
- The most effective desiccant for seeds is silica gel.
- Water suckers, sword suckers, corm suckers, and root suckers are types of suckers in banana cultivation, with sword suckers being ideal for replanting.
