What is more productive for eating? Take carrots, for example. If I plant giant variety carrot seeds in a 5-gallon pot compared to miniature variety carrot seeds in a 5-gallon pot, and if my goal is only to harvest 5 cm baby carrots, don't I get faster results with the giant variety? When growing onions (giant onion variety) planted on the same day as normal variety of onions, don't I get bigger onions in less days? Let's not talk about compost, fertilizer, or water. Really interested in this question.
Well, this is an interesting question. I don't think it has a "yes or no" answer. It depends so much on the type of vegetable and the variety you're looking at, as well as your personal taste. For instance, you may be quite happy with the taste of a large variety carrot that's pulled up when it's only 5cm, but someone else might not care for it. Why don't you try some experiments on your own, and let us all know what you find.
I find carrot fly a real problem in my garden, which has sandy soil and gets badly infested every year once I start to pull the carrots. I put a barrier up, spray with a garlic solution to try and disguise the carrot smell and grow parsley and spring onions between rows. Do the grubs live in the soil and overwinter? Am trying them in an area of the garden which has never grown root crops before this year but was wondering if you have any tips. Thank you.

Can you grow carrots in the same bed which had parsnips growing from last year's crop? Can I use chicken manure pellets in the soil for the carrots?
Yes, as long as there were no issues with any pests or disease, then it should be fine to grow the carrots there. Chicken pellets are also fine for mixing into the soil. The only issue when using chicken manure is that it's high in nitrogen when fresh, but using aged, composted or pelletized manure is ok.
Am I too late to plant carrot, peas, runners and swede from seed?
When you can plant vegetables is determined by the kind of veggie as well as the variety, and also by the hardiness zone you live in, which tells you the average date for first frost.

I'm growing carrots directly in soil/garden but they are all short stubby carrots, hardly usable.

I wish to make a raised bed for growing carrots and beets. What should my soil mix be? My zone 5.
Use a well-draining mix such as two parts regular garden soil with one part sand or perlite and one part organic material such as well-rotted manure or compost.

Our carrots have been in the grow bag for 7 months. The foliage is splendid but the carrots are pale and tiny at 1" in length and thin. Should I give up on them and throw them on the compost or will they eventually grow into a proper carrot?
Too much nitrogen is what happened. When plants have too much nitrogen, they get very leafy but have little fruit and roots. Give the plant some bone meal or something else containing phosphorous to re-balance the phosphorous and nitrogen in the soil.
