Vegetable Seeds

The most common vegetables seeds used include tomatoes, beans, corn, cabbage, carrots, potatoes, pumpkins, cucumbers, and zucchini. Vegetables seeds vary in sizes, shapes, and colors. These seeds become seedlings which are used to produce highly nutritious vegetables or to extract various types of oil for cooking and other purposes. Temperature changes affect the plant growth greatly. The warm season vegetables can be damaged by frost, while the frost tolerant plants should be cultivated just before the winter time. Carrot, onion, radish, and lettuce are typically grown in areas with lower temperatures. Vegetable seeds require right soil temperatures to thrive or else they will not flourish. Vegetable crops depend on various factors such as appropriate temperature, photo period, seasonal length, precipitation amount and distribution.

All the vegetable crops need suitable growing period before harvest time. Some vegetables such as beans, cucumbers, tomatoes, broccoli, cauliflower and others need two months for proper growth till harvest. Crops such as potatoes, corn, eggplant, brussels sprouts, cabbage and onions need over three months before harvest can take place. The geographic region, too, has an effect upon the seed yield and the quality of the oil which is derived from the seeds of vegetables. India is one of the largest producers of vegetables and one of the leading three vegetable seeds producers.

The production of vegetable seeds requires soils with high water holding capacity for ensuring better growth. With appropriate soil preparation for the various vegetables, the yield is found to be better. The plants can be grown on raised or flat surfaces. Soils temperatures can be changed with inputs of organic manure. The seed beds must be uniform as the vegetable seeds require precision planting for best performance and uniform development. Vegetable seeds are propagated through direct drilling or transplantation methods. Planting at the right time is essential for these crops. Hybrids are increasingly preferred as they bring uniformity in characteristics to various plants and increase vigor, but the seeds of these hybrids are more expensive. Various methods of planting are utilized of which the following two

are notable. The "seed-to-seed" method is one which involves planting of the biennial seed and harvesting of the seed crop the next season. carrots and onions re typically grown similarly. The other method is the "root-to-seed" method which involves the planting of the biennial seed and transplanting of the seed crop in the next season.


Row spacings for the vegetable seed production differs from the fresh market production. The factors taken into consideration for growing the plants include provision of sufficient space for flower development, air movement, machinery cultivation and harvest operations. The same nutrient requirements as fresh market crops are recommended for growing vegetable seeds commercially. Among essential nutrients, boron and molybdenum enable the optimum nitrogen fixation for legume seed crops. For plant propagation, fertilizer application at planting and flowering are advised. The plants are vulnerable to the same insect infestations and diseases as the fresh market crops. Market crops such as onion, radish, broccoli and cabbage are harvested prior to the flowering. As a result, they are grown in areas with cooler temperatures and are unsuited to seed crops. Seed crops, essentially, require longer periods and warmer temperatures for maturation.
