Bomba Rice
Oryza sativa var. bomba
grassBomba is a short-grain, starchy rice variety prized for its ability to absorb liquid while maintaining its individual grain structure. Originally from Spain's Valencia region, it is the traditional choice for authentic paella. The grains are slightly shorter and rounder than standard short-grain rice, with a pearly white appearance.

Germination & Seedling
7-14 daysSeeds germinate in water or moist soil, developing first shoots and roots. Seedlings emerge as thin, blade-like leaves within 7-10 days.
Maintain water temperature above 50°F (10°C) for germination. Keep paddies flooded or soil consistently moist. Protect from birds and pests.
Vegetative
30-50 daysPlant develops multiple tillers (shoots) and an extensive root system. Leaf blades are long, narrow, and green. Height increases rapidly.
Maintain 2-5 inches of standing water. Apply nitrogen fertilizer in split doses at 20-30 and 40-50 days after emergence. Monitor for weeds and pests.
Reproductive/Flowering
15-25 daysPanicles (flowering structures) emerge from leaf sheaths. Small flowers develop within spikelets. Plant reaches maximum height.
Maintain consistent water levels; do not drain paddies. Continue pest monitoring. Apply potassium fertilizer if needed to strengthen stems and improve grain fill.
Grain Filling
20-30 daysFlorets are fertilized and grains begin to swell with starch. Panicles become heavier and may droop. Husks and grains transition to yellow-gold color.
Gradually reduce water levels toward harvest. Ensure adequate potassium and micronutrients. Protect from late-season pests and diseases.
Maturity & Harvest
5-10 days before harvestGrains become hard and fully mature. Grain moisture drops to 20-25%. Panicles are gold to tan colored and fully erect or drooping.
Drain paddies 7-10 days before harvest. Harvest when grain moisture reaches 20-25% (can test with moisture meter). Cut, thresh, and dry grains to 12-14% moisture for storage.

Common Pests
-
Monitor for infested tillers; remove and destroy affected plants. Use pheromone traps. Apply neem oil or spinosad if populations are high. Practice crop rotation.
-
Use resistant varieties. Improve water management and avoid excessive nitrogen. Apply copper fungicides or sulfur if needed. Remove infected plant debris.
-
Monitor leaves for characteristic folding. Hand-remove infested leaves. Use beneficial parasitoids. Apply neem oil or spinosad for severe infestations.
-
Maintain proper water levels (flooding reduces populations). Use yellow sticky traps. Apply spinosad if populations are high.
-
Primarily a storage pest. Store dried grain at moisture levels below 12-14% and cool temperatures. Use diatomaceous earth or neem oil in storage bins.
Uses
Paella & Spanish Rice Dishes
CulinaryBomba rice is the traditional and preferred rice variety for authentic paella and other Spanish rice dishes. Its unique ability to absorb liquid without becoming mushy while maintaining firm, separate grains makes it ideal for these preparations. [source]
Risotto Alternatives
CulinaryThough not traditional risotto rice, Bomba's starch content allows it to create creamy dishes when stirred with broth. It works well in Mediterranean-style rice preparations. [source]
Rice Bowls & Grain Salads
CulinaryThe firm, defined grains of Bomba rice work well in rice bowls and grain-based salads where maintaining texture is important, adding a pleasant bite to composed dishes. [source]
Traditional Food Culture
HouseholdBomba rice carries significant cultural and culinary heritage as the historic rice of the Valencia region in Spain, integral to regional identity and traditional cooking practices. [source]
Paddy Ecosystems
WildlifeRice paddies, especially those with integrated management practices, support diverse aquatic and wetland wildlife including fish, amphibians, and migratory birds. [source]
Harvest Tips
Harvest when grain moisture is 20-25% (typically 120-150 days after planting). Cut panicles with sickles or machine harvesters. Thresh to separate grains from husks. Dry grains to 12-14% moisture content for proper storage. Bomba rice's primary use is paella, where its ability to absorb broth while maintaining grain structure is essential; avoid over-stirring during cooking to preserve individual grain integrity.
Fun Facts
- 🌱 Bomba rice originates from Spain's Valencia region and is considered the only authentic rice for true paella Valenciana; some Spanish purists argue that using any other rice variety disqualifies a dish from being called 'paella.'
- 🌱 Bomba grains can absorb up to 3 times their weight in liquid while remaining firm and separate, compared to 2 times for standard short-grain rice—a characteristic prized by Spanish cooks for centuries.
- 🌱 Rice paddies have been cultivated for over 8,000 years and remain one of the world's most important staple crops, feeding more than half the global population.
