Vegetable seed production under protected conditions can be a commercial practice that offers many advantages over open field production:
Higher seed yield: Seed yield can be 2–4 times higher than open field production.
Better seed quality: Seeds are healthier, virus-free, and genetically pure.
Protection from adverse conditions: Seeds can be produced under adverse climatic conditions, such as unseasonal rains, frost, severe cold, and heavy rains.
Easier management: Training, pruning, and hand pollination are easier to manage under protected conditions.
Reduced isolation distance: The need for isolation distance in cross-pollinated vegetables is minimized.
Protection from biotic and abiotic stress: Protected conditions can help overcome biotic and abiotic stress.
Water, fertilizer, and land conservation: Protected conditions can help conserve water, fertilizer, and land
