BPVC-104 IGNOU Handwritten Assignment 2026-27

BPVC-104: Comprehensive Handwritten Assignment for Post-Harvest Management of Food Produce

The BPVC-104 course under the Bachelor of Science (Food Safety and Quality Management) program at IGNOU focuses on Post-Harvest Management of Food Produce, a critical discipline within agricultural sciences. This subject bridges the gap between crop harvesting and market delivery, emphasizing food preservation techniques, quality maintenance, and efficient supply chain management. Through a structured curriculum, students explore biological, chemical, and physical principles governing post-harvest losses, while also analyzing storage technologies, transportation logistics, and marketing strategies tailored to perishable commodities. The course is designed to equip learners with practical and theoretical insights essential for reducing food waste, enhancing shelf life, and ensuring nutritional integrity—key objectives aligned with global food security initiatives.

Key Syllabus Units Covered

• Block-2 Post-Harvest Management: This unit delves into harvesting techniques, maturity indices, and immediate post-harvest handling to minimize mechanical damage and microbial contamination. Topics include optimal harvesting times, field cooling methods, and packaging standards for different produce categories.
• Block-3 Storage, Transportation and Marketing: Students examine controlled atmosphere storage (CAS), modified atmosphere packaging (MAP), and refrigeration systems to extend shelf life. The unit also covers transportation protocols—such as temperature regulation and ventilation—to prevent spoilage during transit, alongside market chain dynamics affecting produce quality.
• Block-4 Post-Harvest Management of Fruits and Vegetables: Specialized techniques for fruits (e.g., ethylene regulation in apples, citrus handling) and vegetables (e.g., leafy greens, root crops) are analyzed. Key concepts include respiration management, ethylene inhibitors, and post-harvest diseases like rot and mold.
• Block-6 Post-Harvest Management of Cereals, Pulses and Oilseeds: Focuses on drying, threshing, and storage methods for grains and legumes to prevent insect infestations and mycotoxin contamination. The unit also explores grain quality parameters and post-harvest processing technologies like dehulling and polishing.

Frequently Asked Questions

Q: What is the passing mark for BPVC-104 assignments, and how are they evaluated?
A: Assignments in BPVC-104 carry 20 marks (20% of the total course weight), with a minimum passing score of 40% across all assignments and exams combined. Evaluation criteria include clarity of concepts, application of post-harvest principles, and adherence to academic writing standards as per IGNOU guidelines.

Q: Are practical demonstrations included in BPVC-104, and do they affect assignment scores?
A: While BPVC-104 does not mandate in-person lab sessions, theoretical assignments often require students to apply practical concepts (e.g., calculating storage losses or designing packaging solutions). These are assessed based on logical reasoning and curriculum-aligned problem-solving, not physical experiments.
