About PitayaCalc
📱 PitayaCalc - Scientific Calculator for Growing Dragon Fruit
About the App
PitayaCalc is the first specialized agricultural calculator developed exclusively for the cultivation of pitaya (Hylocereus undatus), also known as dragon fruit. Created by Agroaki, the app brings together in one place the main mathematical models and validated scientific equations for this expanding crop in Brazil.
With PitayaCalc, rural producers, agricultural technicians, or agronomy students can perform precise calculations on biomass, mineral nutrition, fertilization, productivity, drying kinetics, and economic viability, all based on academic research published in high-impact scientific journals.
📊 Calculation Modules
🌱 Biomass and Growth
- Estimation of total plant dry mass based on Days After Planting (DAP)
- Identification of the development phase (Growth or Productive)
- Growth curve
🧪 Nutrients and Foliar Analysis
- Evaluation of Nitrogen (N), Phosphorus (P), and Potassium (K) levels in leaves
- Classification: Deficient, Sufficient, or Excess
- Absorption pattern of macro and micronutrients throughout the cycle
🧴 Fertilizer Recommendation
- Calculation of P₂O₅ requirement based on soil phosphorus content
- NPK fertilization response model
- Yield estimate in tons per hectare
📈 Productivity
- Production per plant according to age (1st, 2nd, and 3rd year)
- Adjustment by variety: BRS Âmbar, BRS Granada, BRS Lua, BRS Luz and BRS Minipitaya
- Calculation of total production in tons per cultivated area
- Standard spacing of 3x3m (1,111 plants/ha)
🔥 Drying Kinetics
- Page model for estimating residual moisture
- Factors: drying time (hours) and temperature
- Ideal for post-harvest processing and agro-industry
💰 Economic Analysis
- Payback (return on investment)
- Break-even point (minimum quantity to cover costs)
- Estimated annual profit and ROI (Return on Investment)
- Customizable with real producer data
👨🌾 Who is PitayaCalc for?
- Rural producers who cultivate or wish to start cultivating dragon fruit
- Agricultural engineers and agricultural technicians who provide assistance to producers
- Students of agronomy and related fields seeking practical learning
- Researchers who need agile and reliable calculation tools
- Agro-industries that process dragon fruit for pulp, dehydrated products, or derivatives
🛡️ Privacy and Security
PitayaCalc was developed with a "privacy-first" approach:
- ❌ Does NOT require account creation or login
- ❌ Does NOT collect personal data (name, email, phone number)
- ❌ Does NOT track location via GPS
- ❌ Does NOT send cultivation data to servers
- ✅ All data remains only on your device
- ✅ Works offline for all calculations (only ads require internet)
In compliance with the General Data Protection Law (LGPD), you have complete control over your information. To delete your data, simply uninstall the application or clear the cache.
