Seeds are the key to the harvest
For consistently high yields of vegetables, it is critical seed quality, namely, seed... A preliminary assessment of seeds can even be carried out visually: quality seeds must be well executed, filled.
Faintness and wrinkling may indicate that the seeds were harvested unripe. Among the seeds there should be no admixtures of seeds of other crops, litter, as well as ugly, broken or small specimens. Only full-fledged seeds are the key to a future high yield In order to correctly decide which seeds - varietal or hybrid to purchase for sowing, you need to figure out what is their difference
Hybrid seeds are usually denoted with the letter F, and the number next to this letter indicates which generation it is. Such seeds are obtained by crossing two specially selected parental forms, and hybrid plants are superior to their parents in all respects. This superiority in them is not genetically fixed, therefore, seeds from hybrids are not harvested and used. In subsequent generations, traits splitting occurs, and yield, as a rule, drops sharply. Hybrids are usually strictly specialized and require adherence to the necessary agricultural technology. All recommendations for care and feeding must be followed. Without this, hybrids will not be able to fully manifest their benefits.
Varietal seeds imply greater plasticity, plants from them, as a rule, are less whimsical, more resistant to many diseases and put up with other unfavorable factors. But in terms of yield, they can be twice as low as hybrids.
An important criterion for the quality of seeds is their germination. The seeds of those vegetable plants that develop and ripen inside the fruit have the highest germination (80-95%): tomato, cucumber, squash, melon, watermelon, squash, pumpkin, etc. This is due to the fact that when the fruit ripens, the seeds ripen in it at the same time. In the same plants, the seeds of which are in panicles, pods or umbrellas (or in other types of inflorescences), the flowering, which means that the maturation of the seeds is stretched, and by the time of collection the seeds on the late shoots do not have time to ripen. In celery, seed germination ranges from 40-80%, in cruciferous plants - 60-90%, in onions - 50-80%, in dill it is about 60%. Seeds with such germination are classified as class 1.
Therefore, when buying seeds, you should focus on the lower germination rate in order to correctly calculate the required number of seeds for sowing on the prepared area. It should also be borne in mind that long-stored seeds have a reduced germination energy, that is, even with a preserved high germination capacity, seedlings from such seeds are usually delayed and are uneven. (You can get some information about the shelf life and germination of seeds from the table on this page.)
|Culture||Shelf life of seeds,|
|Emergence of seedlings, sowing dry seeds,|
|Minimum germination temperature,|
|Zucchini, squash, pumpkin||6–8||4–8||10–12|
|White cabbage, cauliflower, kohlrabi||4–5||3–6||2–3|
|Black onion, batun, leek||3–4||8–18||2–3|
High, and, most importantly, stable yields can be obtained only when growing zoned vegetable crops. Having been on a variety trial for several years, varieties and hybrids that have shown the best results in a given area will be considered released in that particular area.
Only here, in the soil and climatic conditions familiar to themselves, the zoned varieties and hybrids are able to fully demonstrate their qualities. Now there is such a thing as "author's seeds", usually at the time of sale they are still on trial or registered as an "amateur variety" (if they are not suitable for mechanized cultivation). Among the amateur varieties, there are very interesting and prolific plants with excellent taste. Hobbyists presenting their seeds usually try not to lose face.
In conclusion, it is worth noting that although now the choice of seeds is huge and many new products have appeared, you still should not immediately abandon old, proven varieties and hybrids. It is better to test any novelty first on your site, and then draw conclusions.

First, you need to know that cucumber seeds do not lose their germination for 6 to 8 years. It is preferable to take cucumber seeds for 3-4 years, they have the highest germination and they will form more female flowers. Secondly, cucumber seeds are varietal and hybrid, they are denoted by the letter F1. Hybrid varieties - only for one year, you won't get seeds from them, but buying varietal varieties, you can count on getting your own seeds. Visually good seeds will always be plump, in water they will sink to the bottom, and empty ones will float up. This allows you to immediately sift out empty seeds when planting. For pickling, it is better to take varietal seeds, from which the most crunchy and aromatic cucumbers are obtained.
When choosing seeds, you immediately need to know where you will plant them, in open ground or in a greenhouse. For open ground, it is preferable to take bee-pollinated seeds, it is advisable to take not one variety, but several, or parthenocarpic ones (insects or bees do not need insects or bees to pollinate them independently), so you insure yourself to some extent from weather conditions. For greenhouses, take either different varieties of bee-pollinated ones, or different varieties of parthenocarpic cucumber seeds. It is better not to mix them in a greenhouse. It doesn't matter for open ground.
Your petunia seedlings are interesting, profitable and convenient. Only at first glance it seems that it is difficult to grow it. But if you follow the sowing dates, choose the right varieties, purchase high-quality seeds and observe the necessary conditions for the development of seedlings, you can easily grow high-quality seedlings in an ordinary apartment.
Petunia is a very grateful and responsive flower. And since the selection does not stand still, then in the next season it will surprise us and will certainly delight us all summer.
Petunia blends well with other annuals and perennial flowers.
Petunias have a wide variety of colors: red, white, purple, blue, pink. There are two-color varieties. All the colors are countless!
And the shape of the flower does not lag behind in diversity: there are terry, there are fringed hybrids. I love terry petunias very much - they look very impressive. They can be planted both in a flower bed and in pots. .
Ampel petunias also look good in pots.
It is necessary to pay attention to a number of key characteristics that are indicated by the manufacturer of a particular variety. Issues related to copyright are also important.
It is important to pay attention in particular to the ripening times, growing conditions, the recommended fertilizers and remedies. It should also be absolutely clear who exactly released this or that variety, that is, which organization.
It is important to read about certain varieties and compare information about each with specific climatic conditions.
Of course, it is worth focusing on the average statistical indicators, however, it will clearly not be superfluous to imagine what will happen in the case of certain climatic maximums or minimums.
At the very least, it will be clear what force majeure circumstances can happen and what they can lead to.
Seeds of the most popular varieties and hybrids of melons, popular among professional farmers in Ukraine, giving high-quality fruits and high yields, well adapted to various growing conditions throughout Ukraine: in open ground, greenhouses, film tunnels. The presented melon seeds are the leaders among the varieties that exist today, which are grown throughout Europe. The fruits have excellent taste and marketability, high sugar content, equally good cultivation results, both in the south of Ukraine and in more northern regions. In this section, you can buy melon seeds at competitive wholesale prices.
As a rule, for LED luminaires, this height is about 20-30 cm above the top leaves plants.
Greenhouse phyto-lamps are hung at a height of 20 cm to 1.5 meters from the top sheet.
Supplementing winter greens - parsley with phytolamps.
The seedlings begin to light up after the emergence of seedlings, the first two weeks are given additional lighting, so that daylight hours eventually reach 14-16 hours (the first 2 weeks after the emergence of seedlings), after a couple of weeks, the additional lighting time is reduced to 12-14 hours.
Be sure to maintain the Day / Night mode, do not leave the light on all 24 hours a day.
Supplementary lighting of seedlings and indoor plants with a conventional phytolamp inserted into a home desk lamp.
This can be determined by the light from the lamp), the plants can stand slightly beyond the scope of the lamp, but not much. It is ideal to swap plants periodically so that all parts of the seedlings receive enough light for normal growth and development.
One 10-15 W LED light bulb can illuminate up to 1 sq. M. with a height of about 50 cm.
If you have a mount (the need for it was mentioned above), then another useful device can be an on and off timer. However, in many modern phyto-lamps (especially in desktop phyto lamps it is often found) it is already built-in.
